Ultimate glossary of crypto currency terms, acronyms and abbreviations
Aryacoin is a new cryptocurrency, which allows for decentralized, peer to peer transactions of electronic cash. It is like Bitcoin and Litecoin, but the trading of the coin occurs on sales platforms that have no restriction to use. Further, it was created with the goal of addressing the double spend issues of Bitcoin and does so using a timestamp server to verify transactions. It works by taking the hash of a block of items to be timestamped and widely publishing the hash. The timestamp proves that the data must have existed at the time in order to get the hash. Each timestamp then includes the previous timestamp in its hash, forming a chain. The Aryacoin team is continuously developing new use cases for the coin, including exchanges where users can exchange the coins without any fees or restrictions, and offline options where the coins can be bought and sold for cash. The coins can also be used on the company’s other platform, mrdigicoin.io. Along with the coin, there is a digital wallet that can be created and controlled by the user entirely, with no control being retained by the Aryacoin team.
The concept of Blockchain first came to fame in October 2008, as part of a proposal for Bitcoin, with the aim to create P2P money without banks. Bitcoin introduced a novel solution to the age-old human problem of trust. The underlying blockchain technology allows us to trust the outputs of the system without trusting any actor within it. People and institutions who do not know or trust each other, reside in different countries, are subject to different jurisdictions, and who have no legally binding agreements with each other, can now interact over the Internet without the need for trusted third parties like banks, Internet platforms, or other types of clearing institutions. When bitcoin was launched it was revolutionary allowing people to transfer money to anytime and anywhere with very low transaction fees . It was decentralized and their is no third party involved in the transaction , only the sender and receiver were involved. This paper provide a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions.The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes. Bitcoin was made so that it would not be controlled or regulated but now exchanges and governments are regulating bitcoin and other cryptocurrencies at every step. Aryacoin was developed to overcome these restrictions on a free currency. Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community.
1.1 OVERVIEW ABOUT ARYACOIN
Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community. Aryacoin is a blockchain based project that allows users to access their wallet on the web and mobile browsers, using their login details. Aryacoin can be mined; it also can be exchanged by other digital currencies in several world-famous exchanges such as Hitbtc, CoinEx, P2pb2b, WhiteBit, Changelly and is also listed in reputable wallets such as Coinomi and Guarda. Aryacoin is a coin, which can be used by anyone looking to use cryptocurrency which allows them to keep their privacy even when buying/selling the coin along with while using the coin during transactions. Proof of work and cryptographic hashes allows transactions to verified. Stable Fee Per AYA is a unique feature of Aryacoin, so by increasing the amount or volume of the transaction, there is no change in the fee within the network, which means that the fee for sending an amount less than 1 AYA is equal to several hundred million AYA. Another unique feature of Aryacoin is the undetectability of transactions in Explorer, such as the DASH and Monero, of course, this operation is unique to Aryacoin. Using Aryacoin digital currency, like other currencies, international transactions can be done very quickly and there are no limitations in this area as the creators claim. Aryacoin aims to allow users to access the Aryacoin wallet via the web and mobile browsers using their login details. Aryacoin is a peer-to-peer electronic cash system that enables users to send and receive payments directly from one party to another, and allow them to transfer funds across borders with no restriction or third party involvement. The blockchain-based system embraces the digital signature, which prevents double spending and low transfer fees, which enables users to transfer huge amounts with very low fees. The proof-of-work consensus mechanism allows each transaction to be verified and confirmed, while anonymity enables users to use the coin anywhere at any time. According to the website of the operation, each wallet is divided into 2 or more AYA wallet addresses for each transaction, and depending on the volume of the transaction block, the origin, and destination of transactions in the network can not be traced and displayed to the public. In fact, each wallet in Aryacoin consists of a total of several wallets. The number of these wallets increases per transaction to increase both security and privacy. Aryacoin also uses the dPoW protocol. In the dPoW protocol, a second layer is added to the network to verify transactions, which makes “51% attack” impossible even with more than half of the network hash, and blocks whose Blockchain uses this second layer of security never run the risk of 51% attacks. AYA has been listed on a number of crypto exchanges, unlike other main cryptocurrencies, it cannot be directly purchased with fiats money. However, You can still easily buy this coin by first buying Bitcoin from any large exchanges and then transfer to the exchange that offers to trade this coin.
1.1.1 ARYACOIN HISTORY
Aryacoin (AYA) is a new cryptocurrency, which has been created by a group of Iranian developers, is an altcoin which allows for decentralised, peer to peer transactions of electronic cash without any fees whatsoever. Along with the coin, there is a digital wallet that can be created and managed by the user entirely, with no control being retained by the Aryacoin team. Aryacoin’s founder, Kiumars Parsa, has been a fan of alternative currencies and particularly Bitcoin. “We see people from all around the world using Blockchain technology and the great benefits that came with it and it then that I decided to solve this puzzle for find a way of bringing the last missing piece to the jigsaw. The idea for Aryacoin was born.” Parsa said. Parsa and his team of Iranian ex-pats not only persevered but expedited the project and just a year later, in the summer of 2019, the first version of Aryacoin was released. In 2020, Aryacoin is the first and only Iranian coin listed on CMC. Parsa goes on to state that it is now the strength of the community that has invested in the coin that will ultimately drive its success, alongside its robust technology and appealing 0% network fees. “We have thousands of voices behind Aryacoin. People for the people make this coin. It is a massive shout out for democracy. This had made us base the whole team strategy on the benefits for both our users and our traders.” “One key example is that the network fee on AYA Blockchain is 0%. Yes, absolutely nothing, which which differentiates us from other networks. What also differentiates us from other coins is that we have AYAPAY which is the first cryptocurrency Gateway in the world which does not save funds on third party storage with all funds being forwarded directly to any wallet address that the Gateway owner requests”. “So for the first time ever, and unlike other gateways, incoming funds will be saved on the users account with submitted withdrawal requests then made on the Gateway host website. In AYAPAY which has also been developed by the Aryacoin team, all funds without extra fees or extra costs will directly forwarded to users wallets. We have named this technology as CloudWithdrawal.” “We are continuously challenging ourselves as it is a crowded marketplace. We are striving to have a safer Blockchain against 51% attacks, faster confirmations speeds of transactions, cheaper network fee, growing the market by cooperation with Top tier Exchangers.”
1.1.2 ARYACOIN’S MAIN GOAL

1.1.3 PROBLEM ARYACOIN SEEKS TO SOLVE
Aryacoin aims to provide a long-term solution to the problem of double spending, which is still common in the crypto market. The developers of the system have created a peer-to-peer distributed timestamp server that generates computational proof of the transactions as they occur. Besides, the system remains secure provided honest nodes control more CPU power than any cooperating group of attacker nodes. While Bitcoin was designed not to be regulated or controlled, many exchanges and governments have put regulatory measures on the pioneer cryptocurrency at every step. Aryacoin aims to overcome these restrictions as a free digital currency.

Offline Exchanges They are also working with different offline vendors which would enable them to buy and sell the coins directly to our users on a fixed/variable price this would allow easy buy/sell directly using cash . This would allow the coins to be accessible to users without any restrictions which most of the online exchanges have, also increase the value and number of users along with new ways to spend the coin. This would increase anonymity level of the coin. In addition, introduce new users into the cryptomarket and technology. Creating a revolution, which educates people about crypto and introduce them to the crypto world, which introduces a completely new group of people into crypto and a move towards a Decentralized future! 4. Transactions When it comes to transactions, Aryacoin embraces a chain of digital signatures, where each owner simply transfers the coin to the next person by digitally signing a hash of the previous transaction and the public key of the next owner. The recipient can then verify the signatures to confirm the chain of ownership. Importantly, Aryacoin comes with a trusted central authority that checks every transaction for double spending. 5. Business Partner with Simplex Aryacoin is the first and only Iranian digital currency that managed to obtain a trading license in other countries. In collaboration with the foundation and financial giant Simplex, a major cryptocurrency company that has large companies such as Binance, P2P, Changelly, etc. Aryacoin has been licensed to enter the world’s major exchanges, as well as the possibility of purchasing AYA through Credit Cards, which will begin in the second half of 2020. Also, the possibility of purchasing Aryacoin through Visa and MasterCard credit cards will be activated simultaneously inside the Aryacoin site. plus, in less than a year, AYA will be placed next to big names such as CoinCapMarket, Coinomi, P2P, Coinpayments and many other world-class brands today.

The injection of $ 1 million a day in liquidity by the WhiteBite exchange to maintain and support the price of Tether and eliminate the Tether fluctuations with Bitcoin instabilities used by profiteers to become a matter of course.
1.1.8 HOW DOES ARYACOIN WORK?
Aryacoin (AYA) tries to ensure a high level of security and privacy. The team has made sure to eliminate any trading restrictions for the network users: no verification is required to carry out transactions on AYA, making the project truly anonymous, decentralized, and giving it a real use in day-to-day life. The Delayed-Proof-of-Work (dPoW) algorithm makes the Aryacoin blockchain immune to any attempts of a 51% attack. AYA defines a coin as a chain of digital signatures — each owner transfers the coin to the next owner by digitally signing the hash of the previous transaction and the public key of the next owner, and the receiver verifies the signatures and the chain of ownership.
2. ARYACOIN TECHNOLOGY
They use a proof-of-work system similar to Adam Back’s Hashcash to implement a distributed timestamp server on a peer-to-peer basis, rather than newspaper or Usenet publications. The proof-of-work involves scanning for a value that when hashed, such as with SHA-256, the hash begins with a number of zero bits. The average work required is exponential in the number of zero bits required and can be verified by executing a single hash. For their timestamp network, they implement the proof-of-work by incrementing a nonce in the block until a value is found that gives the block’s hash the required zero bits. Once the CPU effort has been expended to make it satisfy the proof-of-work, the block cannot be changed without redoing the work. As later blocks are chained after it, the work to change the block would include redoing all the blocks after it. The proof-of-work also solves the problem of determining representation in majority decision making. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone able to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote. The majority decision is represented by the longest chain, which has the greatest proof-of-work effort invested in it. If honest nodes control a majority of CPU power, the honest chain will grow the fastest and outpace any competing chains. To modify a past block, an attacker would have to redo the proof-of-work of the block and all blocks after it, then catch up with, and surpass the work of the honest nodes.
The steps to run the network are as follows:
New transactions are broadcast to all nodes.
Each node collects new transactions into a block.
Each node works on finding a difficult proof-of-work for its block.
When a node finds a proof-of-work, it broadcasts the block to all nodes.
Nodes accept the block only if all transactions in it are valid and not already spent.
This is a very simple system that makes the network fast and scalable, while also providing a decent level of anonymity for all users. Users can send their transactions to any of the public nodes to be broadcast, and the private key of the sender’s address should sign any transaction sent to the nodes. This way, all transaction info remains strictly confidential. It also allows users to send transactions directly to the node from any place at any time and allows the transferring of huge amounts with very low fees.
2.3 AYAPAY PAYMENT SERVICES GATEWAY:
According to creators Aryacoin, the development team has succeeded in inventing a new blockchain technology for the first time in the world, which is undoubtedly a big step and great news for all digital currency enthusiasts around the world. This new technology has been implemented on the Aryacoin AYAPAY platform and was unveiled on October 2. AYAPAY payment platform is the only payment gateway in the world that does not save money in users’ accounts and transfers incoming coins directly to any wallet address requested by the gateway owner without any additional transaction or fee. In other similar systems or even systems such as PayPal, money is stored in the user account.
2.4 CONSENSUS ALGORITHM IN ARYACOIN
The devs introduced the Delayed-Proof-of-Work (dPoW) algorithm, which represents a hybrid consensus method that allows one blockchain to take advantage of the security provided by the hashing power of another blockchain. The AYA blockchain works on dPoW and can use such consensus methods as Proof-of-Work (PoW) or Proof-of-Stake (PoS) and join to any desired PoW blockchain. The main purpose of this is to allow the blockchain to continue operating without notary nodes on the basis of its original consensus method. In this situation, additional security will no longer be provided through the attached blockchain, but this is not a particularly significant problem. dPoW can improve the security level and reduce energy consumption for any blockchain.
2.5 DOUBLE-SPEND PROBLEM AND SOLUTION
One of the main problems in the blockchain world is that a receiver is unable to verify whether or not one of the senders did not double-spend. Aryacoin provides the solution, and has established a trusted central authority, or mint, that checks every transaction for double-spending. Only the mint can issue a new coin and all the coins issued directly from the mint are trusted and cannot be double-spent. However, such a system cannot therefore be fully decentralized because it depends on the company running the mint, similar to a bank. Aryacoin implements a scheme where the receiver knows that the previous owners did not sign any earlier transactions. The mint is aware of all transactions including which of them arrived first. The developers used an interesting solution called the Timestamp Server, which works by taking a hash of a block of items to be ‘timestamped’ and publishing the hash. Each timestamp includes the previous timestamp in its hash, forming a chain. To modify a block, an attacker would have to redo the proof-of-work of all previous blocks, then catch up with, and surpass the work of the honest nodes. This is almost impossible, and makes the network processes more secure. The proof-of-work difficulty varies according to circumstances. Such an approach ensures reliability and high throughput.
3. ARYACOIN ROADMAP

Binance Support Number (+𝟏) 445*𝟗𝟎0*1𝟒𝟐𝟓 ♚ USA Help Phone
These days, the overall economy is just moving towards an all out cutting edge eco-system and subsequently everything starting from money move to theory are going paperless. Also, the cryptographic cash is the latest similarly as the most capable development to the field of electronic portion. The cryptographic cash is basically an exchange medium like the standard money related structures like USD, yet it is essentially planned for exchanging progressed information. Besides, here are a segment of the reasons why computerized BinanceSupport has gotten so celebrated in the continuous past. Asset moves: The budgetary specialists every now and again portray computerized cash as the technique that on a particular level can be used to actualize and execute two-party contracts on the things like land and vehicles. In addition, the advanced cash condition is similarly used to encourage some master BinanceSupport methods. Binance Supports: In the normal techniques for proficient connections, legitimate representatives, experts, and mediators can incorporate some unprecedented cost and enough unpredictability to even the immediate BinanceSupport. Moreover, there are operational expense, commissions, regulatory work and some other unprecedented conditions that may apply too. Of course, the cryptographic cash Binance Supports are adjusted issues that essentially happen on some common structure of frameworks organization. This thing achieves better clearness in setting up audit trails, more important obligation and less confusion over creation portions. BinanceSupport charges: Transaction costs normally trim down the advantages of an individual, fundamentally if the individual performs stores of cash related Binance Supports every month. Nonetheless, as the data excavators do figuring that generally makes different sorts of cryptographic types of cash get the compensation from the framework being referred to and hence here the BinanceSupport costs never apply. Nevertheless, one may need to pay a particular proportion of outside costs for associating with the organizations of any untouchable organization organizations to keep up the computerized BinanceSupport wallet. More mystery methodology for BinanceSupport: Under the credit/cash structures, the all out BinanceSupport history can transform into a reference report for the credit association or bank included, come what may while making BinanceSupport. At the most clear level, this may recall a check for the record acclimates to guarantee the openness of good resources. Regardless, by virtue of cryptographic cash, every BinanceSupport made between two social events is considered as a stand-out exchange where the terms can be agreed and organized. Additionally, here the information exchange is performed on a "push" premise where one can definitely send what he/she seizes the opportunity to send to the recipient. This thing thoroughly guarantees the security of the money related history similarly as the threat of character or record theft. Less complex trading system all around: Although advanced monetary forms are commonly seen as the real tenders on the open levels, these are not dependent upon the advance costs, exchange rates, BinanceSupport charges or whatever different costs that are constrained by a particular country. Likewise, by using the appropriated procedure for the blockchain advancement, Binance Supports, and cross-periphery Binance Supports can be performed without any snares. More conspicuous induction to the credits: The Internet and the serious data move are the media that ease advanced cash exchanges. Thusly, these organizations are open to people with data on the cryptographic cash masterminds, a helpful data affiliation and snappy action to the relevant passages and locales. The advanced BinanceSupport organic framework is prepared for making BinanceSupport taking care of and asset move open to all the wiling people after the fundamental establishment is accessible set up. Strong security: After favoring the computerized BinanceSupport move, this can't be exchanged like the "charge-back" Binance Supports of different Visa associations. This can be a help against the deception that necessities to choose explicit understandings among vendors and buyers about limits of the appearance technique or a blunder in the BinanceSupport. Adaptability: There are around 1200 sorts of altcoins or cryptographic types of cash present in the current world. A bit of these are a bit of transient, anyway an adequate degree is used for express cases, which depict the versatility of this marvel. Blockchains, sidechains, mining - wordings in the incognito universe of cryptographic cash continue aggregating by minutes. Notwithstanding the way that it sounds ludicrous to introduce new fiscal terms in a successfully astounding universe of store, advanced types of cash offer a really vital response for most likely the best burden in the current BinanceSupport market - security of BinanceSupport in an automated world. Advanced cash is a describing and irksome improvement in the snappy moving universe of parity tech, a proper response to the necessity for a protected vehicle of exchange the hours of virtual BinanceSupport. In when game plans are simply digits and numbers, cryptographic cash proposes to do unequivocally that! In the most basic kind of the term, advanced cash is a proof-of-thought for elective virtual money that ensures ensured about, obscure Binance Supports through shared online work sorting out. The misnomer is considerably more a property rather than veritable money. Rather than standard money, cryptographic cash models work without a central influence, as a decentralized progressed instrument. In a scattered advanced BinanceSupport instrument, the money is given, directed and grasped by the total system peer compose - the tireless activity of which is known as mining on a buddy's machine. Successful diggers get coins too in vitality about their time and resources utilized. At the point when used, the BinanceSupport information is conveyed to a blockchain in the framework under an open key, shielding each coin from being spent twice from a comparable customer. The blockchain can be thought of as the agent's register. Coins are ensured about behind a mystery word made sure about cutting edge wallet addressing the customer. Effortlessly of coins in the serious money world is pre-picked, freed from control, by any individual, affiliations, government components and cash related foundations. The cryptographic cash structure is known for its speed, as BinanceSupport practices over the modernized wallets can rise resources immediately, diverged from the customary budgetary system. It is moreover by and large irreversible by arrangement, further strengthening the chance of mystery and shedding any further chances of following the money back to its special owner. Tragically, the eminent features - speed, security, and anonymity - have moreover made crypto-coins the strategy for BinanceSupport for different unlawful Binance Supports. Much equivalent to the BinanceSupport market in actuality, money rates shift in the serious coin condition. Inferable from the restricted proportion of coins, as enthusiasm for money grows, coins swell in regard. Bitcoin is the greatest and best advanced cash as of recently, with a market head of $15.3 Billion, getting 37.6% of the market and at present assessed at $8,997.31. Bitcoin hit the currency market in December, 2017 by being Binance Supportd at $19,783.21 per coin, before standing up to the startling make a plunge 2018. The fall is generally a result of rising of alternative electronic coins, for instance, Ethereum, NPCcoin, Ripple, EOS, Litecoin and MintChip. On account of hard-coded limits on their deftly, computerized types of cash are considered to keep comparative principles of money related issues as gold - cost is constrained by the confined effortlessly and the progressions of premium. With the steady instabilities in the exchange rates, their reasonability regardless of everything isn't yet clear. Consequently, the enthusiasm for virtual financial structures is more speculation right now than a standard BinanceSupport market. In the wake of present day change, this electronic money is a key bit of imaginative aggravation. From the reason for a nice onlooker, this climb may look empowering, subverting and perplexing simultaneously. While some monetary expert remain far fetched, others believe it to be a lightning change of financial industry. Moderately, the serious coins will oust for the most part quarter of open financial principles in the made countries by 2030. This has recently made another favorable position class near to the customary overall economy and another game plan of theory vehicle will start from cryptofinance in the next years. Starting late, Bitcoin may have ventured out to offer spotlight to various cryptographic types of cash. Nevertheless, this doesn't signal any crash of the cryptographic cash itself. While some cash related advisors highlight over governments' activity in separating the secret world to coordinate the central organization part, others request continuing with the current free-stream. The more standard cryptographic types of cash are, the more examination and rule they attract - an ordinary problem that bewilders the serious note and deteriorates the basic objective of its world. Regardless, the nonattendance of go-betweens and oversight is making it incredibly engaging the examiners and making each day business change https://www.fundamentally.com . To be sure, even the International Monetary Fund (IMF) fears that cryptographic types of cash will remove public banks and overall banking soon. After 2030, common business will be controlled by crypto nimbly chain.
White Paper, Miner, Pizza … | "Old Objects" in the Cryptocurrency Museum
https://preview.redd.it/giu1ssilga151.jpg?width=900&format=pjpg&auto=webp&s=41510785ccdc0d99544ec74229f62427d1c0ce3e Museum has played the role of a time recorder. Talking about bitcoin, more than ten years has passed since the creation of it. Although it is uncomparable to the stock market with a hundred years of history, during the ten years, in the different stages of the development of bitcoin and blockchain have continuously poured in geeks, miners, speculators, newbies, leaving keywords such as sudden rich, myth, scam, belief, revolution, etc. There are also many “old objects” with stories in the “Museum” of the cryptocurrency realm. On Museum Day, let ’s review the stories brought by these “old objects”. The First Digital Currency White Paper — Bitcoin White Paper On Oct. 31, 2008, Satoshi Nakamoto released the Bitcoin white paper — A Peer-to-Peer Electronic Cash System in the cryptographic mail group where he belongs, and Bitcoin was born since then. A white paper is a document that explains the purpose and technology used in cryptocurrency. Usually a cryptocurrency uses the white paper to help people understand what it provides, and it is also an important information channel for investors to understand a project. Therefore, the level of the white paper affects people’s confidence towards the coin. In a word, in the cryptocurrency and blockchain industry, the value of a white paper is equivalent to that of a standard financing speech. The white paper plays a vital role in this emerging market. The First Public Bitcoin-Physical Transaction — Pizza Since Satoshi Nakamoto mined the Bitcoin genesis block on January 3, 2009, Bitcoin has only been spread among the small crowd and has not realized its value. Not until May 22, 2010, Bitcoin enthusiast “Laszlo Hanyecz” bought a pizza coupon worth $25 with 10,000 bitcoins. This is the first public bitcoin-physical transaction. Bitcoin has its price with 0.3 cents per bitcoin. This day has also become the famous “Bitcoin Pizza Day” in Bitcoin history. Bitcoin as the imagination of the financial system has more practical significance. The tenth anniversary is coming. How will you commemorate it? Will you buy a pizza? The First Digital Asset Exchange — Bitcoinmarket.com After the birth of Bitcoin, in addition to mining, the only way to get Bitcoin in the early days was to conduct transactions on forums or IRC (commonly known as Internet Relay Chat). However, this method involves both long transaction time and great security risk. In March 2010, the first digital asset exchange — Bitcoinmarket.com launched. However, due to lack of liquidity and transaction depth, it disappeared soon after its establishment, but Bitcoinmarket.com opened the era of the operation of the cryptocurrency realm exchange 1.0. On June 9, 2011, China’s first Bitcoin exchange — Bitcoin China (BTCChina) launched. Its founder, Yang Linke, translated Bitcoin into Chinese “比特币” for the first time. In 2013, China’s bitcoin trading entered the golden age, and exchanges sprung up. China monopolized more than 90% of the world’s bitcoin transactions. Now, if the top three exchanges Binance, Huobi Global, OKEx are the Exchange 2.0, then the index exchange represented by 58COIN called the 3.0 version, leading the trend. The First Generation of High-Performance Miner — ASIC Miner When Satoshi Nakamoto created Bitcoin, the only way to get it is to use computers (including home computers) to mine, mainly relying on the CPU to calculate. However, as the value of digital currencies such as Bitcoin has become higher and higher, mining has become an industry with the competition is getting fiercer, accompanied by increasing difficulty of mining. Therefore, hardware performance competition starts. In July 2012, the genius Jiang Xinyu (Internet nickname is “Friedcat”) from the junior class of the University of Science and Technology declared at the forum that he could make ASIC miners (chips). As far as mining computing power is concerned, ASICs can be tens of thousands or more higher than the same-generation CPUs and GPUs. At the beginning of 2013, Zhang Nanqian (Pumpkin Zhang), a suspended doctoral student from the Beijing University of Aeronautics and Astronautics, developed the ASIC miner and named it “Avalon”. In June 2013, the Friedcat’s miner USB was finally released, and it maintained 20% of the computing power of the entire network. At the end of 2013, Wu Jihan, used the tens of millions yuan earned from Friedcat through investment, worked together with Jenke group, to develop the Antminer S1. Since then, the miner manufacturer Bitmain began to enter the stage of history. It is no exaggeration to say that Friedcat and Zhang Nangeng have opened the domestic “mining” era. The Birthplace of China’s Bitcoin — Garage Coffee It is not only the “old objects” that record history, but also a place that everyone in the cryptocurrency realm aspires to. Guo Hongcai once said, “Without no The Garage Café, there will be no cryptocurrency realm today. Since it is a very mysterious place that all waves of people from the café joint together to create today’s digital asset industry. ▲ In March 2013, American student Jake Smith successfully purchased a cup of coffee at The Garage Café with 0.131 bitcoins. This move attracted the attention of CCTV, and it conducted an interview. Indeed, The Garage Café is the world ’s first entrepreneurial-themed coffee shop. It has been legendary since its establishment in 2011. The Garage Cafét is not only the core coordinate on China’s Bitcoin map, but also the birthplace of the Chinese cryptocurrency circle, where digital asset realm tycoons including Guo Hongcai, Zhao Dong, Li Xiaolai, Li Lin have made their ways. The development of digital currency is only 11 years old. Through these “old objects”, we review the various stories of this wave of technology together, hoping to help you understand the development process of the digital currency field. Meanwhile, I also remind all practitioners to use history as a mirror and forge ahead.

Bitcoin (BTC) is a peer-to-peer cryptocurrency that aims to function as a means of exchange that is independent of any central authority. BTC can be transferred electronically in a secure, verifiable, and immutable way.
Launched in 2009, BTC is the first virtual currency to solve the double-spending issue by timestamping transactions before broadcasting them to all of the nodes in the Bitcoin network. The Bitcoin Protocol offered a solution to the Byzantine Generals’ Problem with ablockchainnetwork structure, a notion first created byStuart Haber and W. Scott Stornetta in 1991.
Bitcoin’s whitepaper was published pseudonymously in 2008 by an individual, or a group, with the pseudonym “Satoshi Nakamoto”, whose underlying identity has still not been verified.
The Bitcoin protocol uses an SHA-256d-based Proof-of-Work (PoW) algorithm to reach network consensus. Its network has a target block time of 10 minutes and a maximum supply of 21 million tokens, with a decaying token emission rate. To prevent fluctuation of the block time, the network’s block difficulty is re-adjusted through an algorithm based on the past 2016 block times.
With a block size limit capped at 1 megabyte, the Bitcoin Protocol has supported both the Lightning Network, a second-layer infrastructure for payment channels, and Segregated Witness, a soft-fork to increase the number of transactions on a block, as solutions to network scalability.
Bitcoin is a peer-to-peer cryptocurrency that aims to function as a means of exchange and is independent of any central authority. Bitcoins are transferred electronically in a secure, verifiable, and immutable way.
Network validators, whom are often referred to as miners, participate in the SHA-256d-based Proof-of-Work consensus mechanism to determine the next global state of the blockchain.
The Bitcoin protocol has a target block time of 10 minutes, and a maximum supply of 21 million tokens. The only way new bitcoins can be produced is when a block producer generates a new valid block.
The protocol has a token emission rate that halves every 210,000 blocks, or approximately every 4 years.
Unlike public blockchain infrastructures supporting the development of decentralized applications (Ethereum), the Bitcoin protocol is primarily used only for payments, and has only very limited support for smart contract-like functionalities (Bitcoin “Script” is mostly used to create certain conditions before bitcoins are used to be spent).
In the Bitcoin network, anyone can join the network and become a bookkeeping service provider i.e., a validator. All validators are allowed in the race to become the block producer for the next block, yet only the first to complete a computationally heavy task will win. This feature is called Proof of Work (PoW). The probability of any single validator to finish the task first is equal to the percentage of the total network computation power, or hash power, the validator has. For instance, a validator with 5% of the total network computation power will have a 5% chance of completing the task first, and therefore becoming the next block producer. Since anyone can join the race, competition is prone to increase. In the early days, Bitcoin mining was mostly done by personal computer CPUs. As of today, Bitcoin validators, or miners, have opted for dedicated and more powerful devices such as machines based on Application-Specific Integrated Circuit (“ASIC”). Proof of Work secures the network as block producers must have spent resources external to the network (i.e., money to pay electricity), and can provide proof to other participants that they did so. With various miners competing for block rewards, it becomes difficult for one single malicious party to gain network majority (defined as more than 51% of the network’s hash power in the Nakamoto consensus mechanism). The ability to rearrange transactions via 51% attacks indicates another feature of the Nakamoto consensus: the finality of transactions is only probabilistic. Once a block is produced, it is then propagated by the block producer to all other validators to check on the validity of all transactions in that block. The block producer will receive rewards in the network’s native currency (i.e., bitcoin) as all validators approve the block and update their ledgers.
The Bitcoin protocol utilizes the Merkle tree data structure in order to organize hashes of numerous individual transactions into each block. This concept is named after Ralph Merkle, who patented it in 1979. With the use of a Merkle tree, though each block might contain thousands of transactions, it will have the ability to combine all of their hashes and condense them into one, allowing efficient and secure verification of this group of transactions. This single hash called is a Merkle root, which is stored in the Block Header of a block. The Block Header also stores other meta information of a block, such as a hash of the previous Block Header, which enables blocks to be associated in a chain-like structure (hence the name “blockchain”). An illustration of block production in the Bitcoin Protocol is demonstrated below. https://preview.redd.it/m6texxicf3151.png?width=1591&format=png&auto=webp&s=f4253304912ed8370948b9c524e08fef28f1c78d
Block time and mining difficulty
Block time is the period required to create the next block in a network. As mentioned above, the node who solves the computationally intensive task will be allowed to produce the next block. Therefore, block time is directly correlated to the amount of time it takes for a node to find a solution to the task. The Bitcoin protocol sets a target block time of 10 minutes, and attempts to achieve this by introducing a variable named mining difficulty. Mining difficulty refers to how difficult it is for the node to solve the computationally intensive task. If the network sets a high difficulty for the task, while miners have low computational power, which is often referred to as “hashrate”, it would statistically take longer for the nodes to get an answer for the task. If the difficulty is low, but miners have rather strong computational power, statistically, some nodes will be able to solve the task quickly. Therefore, the 10 minute target block time is achieved by constantly and automatically adjusting the mining difficulty according to how much computational power there is amongst the nodes. The average block time of the network is evaluated after a certain number of blocks, and if it is greater than the expected block time, the difficulty level will decrease; if it is less than the expected block time, the difficulty level will increase.
What are orphan blocks?
In a PoW blockchain network, if the block time is too low, it would increase the likelihood of nodes producingorphan blocks, for which they would receive no reward. Orphan blocks are produced by nodes who solved the task but did not broadcast their results to the whole network the quickest due to network latency. It takes time for a message to travel through a network, and it is entirely possible for 2 nodes to complete the task and start to broadcast their results to the network at roughly the same time, while one’s messages are received by all other nodes earlier as the node has low latency. Imagine there is a network latency of 1 minute and a target block time of 2 minutes. A node could solve the task in around 1 minute but his message would take 1 minute to reach the rest of the nodes that are still working on the solution. While his message travels through the network, all the work done by all other nodes during that 1 minute, even if these nodes also complete the task, would go to waste. In this case, 50% of the computational power contributed to the network is wasted. The percentage of wasted computational power would proportionally decrease if the mining difficulty were higher, as it would statistically take longer for miners to complete the task. In other words, if the mining difficulty, and therefore targeted block time is low, miners with powerful and often centralized mining facilities would get a higher chance of becoming the block producer, while the participation of weaker miners would become in vain. This introduces possible centralization and weakens the overall security of the network. However, given a limited amount of transactions that can be stored in a block, making the block time too longwould decrease the number of transactions the network can process per second, negatively affecting network scalability.
3. Bitcoin’s additional features
Segregated Witness (SegWit)
Segregated Witness, often abbreviated as SegWit, is a protocol upgrade proposal that went live in August 2017. SegWit separates witness signatures from transaction-related data. Witness signatures in legacy Bitcoin blocks often take more than 50% of the block size. By removing witness signatures from the transaction block, this protocol upgrade effectively increases the number of transactions that can be stored in a single block, enabling the network to handle more transactions per second. As a result, SegWit increases the scalability of Nakamoto consensus-based blockchain networks like Bitcoin and Litecoin. SegWit also makes transactions cheaper. Since transaction fees are derived from how much data is being processed by the block producer, the more transactions that can be stored in a 1MB block, the cheaper individual transactions become. https://preview.redd.it/depya70mf3151.png?width=1601&format=png&auto=webp&s=a6499aa2131fbf347f8ffd812930b2f7d66be48e The legacy Bitcoin block has a block size limit of 1 megabyte, and any change on the block size would require a network hard-fork. On August 1st 2017, the first hard-fork occurred, leading to the creation of Bitcoin Cash (“BCH”), which introduced an 8 megabyte block size limit. Conversely, Segregated Witness was a soft-fork: it never changed the transaction block size limit of the network. Instead, it added an extended block with an upper limit of 3 megabytes, which contains solely witness signatures, to the 1 megabyte block that contains only transaction data. This new block type can be processed even by nodes that have not completed the SegWit protocol upgrade. Furthermore, the separation of witness signatures from transaction data solves the malleability issue with the original Bitcoin protocol. Without Segregated Witness, these signatures could be altered before the block is validated by miners. Indeed, alterations can be done in such a way that if the system does a mathematical check, the signature would still be valid. However, since the values in the signature are changed, the two signatures would create vastly different hash values. For instance, if a witness signature states “6,” it has a mathematical value of 6, and would create a hash value of 12345. However, if the witness signature were changed to “06”, it would maintain a mathematical value of 6 while creating a (faulty) hash value of 67890. Since the mathematical values are the same, the altered signature remains a valid signature. This would create a bookkeeping issue, as transactions in Nakamoto consensus-based blockchain networks are documented with these hash values, or transaction IDs. Effectively, one can alter a transaction ID to a new one, and the new ID can still be valid. This can create many issues, as illustrated in the below example:
Alice sends Bob 1 BTC, and Bob sends Merchant Carol this 1 BTC for some goods.
Bob sends Carols this 1 BTC, while the transaction from Alice to Bob is not yet validated. Carol sees this incoming transaction of 1 BTC to him, and immediately ships goods to B.
At the moment, the transaction from Alice to Bob is still not confirmed by the network, and Bob can change the witness signature, therefore changing this transaction ID from 12345 to 67890.
Now Carol will not receive his 1 BTC, as the network looks for transaction 12345 to ensure that Bob’s wallet balance is valid.
As this particular transaction ID changed from 12345 to 67890, the transaction from Bob to Carol will fail, and Bob will get his goods while still holding his BTC.
With the Segregated Witness upgrade, such instances can not happen again. This is because the witness signatures are moved outside of the transaction block into an extended block, and altering the witness signature won’t affect the transaction ID. Since the transaction malleability issue is fixed, Segregated Witness also enables the proper functioning of second-layer scalability solutions on the Bitcoin protocol, such as the Lightning Network.
Lightning Network is a second-layer micropayment solution for scalability. Specifically, Lightning Network aims to enable near-instant and low-cost payments between merchants and customers that wish to use bitcoins. Lightning Network was conceptualized in a whitepaper by Joseph Poon and Thaddeus Dryja in 2015. Since then, it has been implemented by multiple companies. The most prominent of them include Blockstream, Lightning Labs, and ACINQ. A list of curated resources relevant to Lightning Network can be found here. In the Lightning Network, if a customer wishes to transact with a merchant, both of them need to open a payment channel, which operates off the Bitcoin blockchain (i.e., off-chain vs. on-chain). None of the transaction details from this payment channel are recorded on the blockchain, and only when the channel is closed will the end result of both party’s wallet balances be updated to the blockchain. The blockchain only serves as a settlement layer for Lightning transactions. Since all transactions done via the payment channel are conducted independently of the Nakamoto consensus, both parties involved in transactions do not need to wait for network confirmation on transactions. Instead, transacting parties would pay transaction fees to Bitcoin miners only when they decide to close the channel. https://preview.redd.it/cy56icarf3151.png?width=1601&format=png&auto=webp&s=b239a63c6a87ec6cc1b18ce2cbd0355f8831c3a8 One limitation to the Lightning Network is that it requires a person to be online to receive transactions attributing towards him. Another limitation in user experience could be that one needs to lock up some funds every time he wishes to open a payment channel, and is only able to use that fund within the channel. However, this does not mean he needs to create new channels every time he wishes to transact with a different person on the Lightning Network. If Alice wants to send money to Carol, but they do not have a payment channel open, they can ask Bob, who has payment channels open to both Alice and Carol, to help make that transaction. Alice will be able to send funds to Bob, and Bob to Carol. Hence, the number of “payment hubs” (i.e., Bob in the previous example) correlates with both the convenience and the usability of the Lightning Network for real-world applications.
Schnorr Signature upgrade proposal
Elliptic Curve Digital Signature Algorithm (“ECDSA”) signatures are used to sign transactions on the Bitcoin blockchain. https://preview.redd.it/hjeqe4l7g3151.png?width=1601&format=png&auto=webp&s=8014fb08fe62ac4d91645499bc0c7e1c04c5d7c4 However, many developers now advocate for replacing ECDSA with Schnorr Signature. Once Schnorr Signatures are implemented, multiple parties can collaborate in producing a signature that is valid for the sum of their public keys. This would primarily be beneficial for network scalability. When multiple addresses were to conduct transactions to a single address, each transaction would require their own signature. With Schnorr Signature, all these signatures would be combined into one. As a result, the network would be able to store more transactions in a single block. https://preview.redd.it/axg3wayag3151.png?width=1601&format=png&auto=webp&s=93d958fa6b0e623caa82ca71fe457b4daa88c71e The reduced size in signatures implies a reduced cost on transaction fees. The group of senders can split the transaction fees for that one group signature, instead of paying for one personal signature individually. Schnorr Signature also improves network privacy and token fungibility. A third-party observer will not be able to detect if a user is sending a multi-signature transaction, since the signature will be in the same format as a single-signature transaction.
4. Economics and supply distribution
The Bitcoin protocol utilizes the Nakamoto consensus, and nodes validate blocks via Proof-of-Work mining. The bitcoin token was not pre-mined, and has a maximum supply of 21 million. The initial reward for a block was 50 BTC per block. Block mining rewards halve every 210,000 blocks. Since the average time for block production on the blockchain is 10 minutes, it implies that the block reward halving events will approximately take place every 4 years. As of May 12th 2020, the block mining rewards are 6.25 BTC per block. Transaction fees also represent a minor revenue stream for miners.
Bitcoin is a decentralized peer-to-peer electronic cash system that does not rely on any central authority like a government or financial institution.

A Beginners Guide to Bitcoin, Blockchain & Cryptocurrency
As cryptocurrency, and blockchain technology become more abundant throughout our society, it’s important to understand the inner workings of this technology, especially if you plan to use cryptocurrency as an investment vehicle. If you’re new to the crypto-sphere, learning about Bitcoin makes it much easier to understand other cryptocurrencies as many other altcoins' technologies are borrowed directly from Bitcoin. Bitcoin is one of those things that you look into only to discover you have more questions than answers, and right as you’re starting to wrap your head around the technology; you discover the fact that Bitcoin has six other variants (forks), the amount of politics at hand, or that there are over a thousand different cryptocurrencies just as complex if not even more complex than Bitcoin. We are currently in the infancy of blockchain technology and the effects of this technology will be as profound as the internet. This isn’t something that’s just going to fade away into history as you may have been led to believe. I believe this is something that will become an integral part of our society, eventually embedded within our technology. If you’re a crypto-newbie, be glad that you're relatively early to the industry. I hope this post will put you on the fast-track to understanding Bitcoin, blockchain, and how a large percentage of cryptocurrencies work.
Altcoin: Short for alternative coin. There are over 1,000 different cryptocurrencies. You’re probably most familiar with Bitcoin. Anything that isn’t Bitcoin is generally referred to as an altcoin. HODL: Misspelling of hold. Dank meme accidentally started by this dude. Hodlers are much more interested in long term gains rather than playing the risky game of trying to time the market. TO THE MOON: When a cryptocurrency’s price rapidly increases. A major price spike of over 1,000% can look like it’s blasting off to the moon. Just be sure you’re wearing your seatbelt when it comes crashing down. FUD: Fear. Uncertainty. Doubt. FOMO: Fear of missing out. Bull Run: Financial term used to describe a rising market. Bear Run: Financial term used to describe a falling market.
What Is Bitcoin?
Bitcoin (BTC) is a decentralized digital currency that uses cryptography to secure and ensure validity of transactions within the network. Hence the term crypto-currency. Decentralization is a key aspect of Bitcoin. There is no CEO of Bitcoin or central authoritative government in control of the currency. The currency is ran and operated by the people, for the people. One of the main development teams behind Bitcoin is blockstream. Bitcoin is a product of blockchain technology. Blockchain is what allows for the security and decentralization of Bitcoin. To understand Bitcoin and other cryptocurrencies, you must understand to some degree, blockchain. This can get extremely technical the further down the rabbit hole you go, and because this is technically a beginners guide, I’m going to try and simplify to the best of my ability and provide resources for further technical reading.
A Brief History
Bitcoin was created by Satoshi Nakamoto. The identity of Nakamoto is unknown. The idea of Bitcoin was first introduced in 2008 when Nakamoto released the Bitcoin white paper - Bitcoin: A Peer-to-Peer Electronic Cash System. Later, in January 2009, Nakamoto announced the Bitcoin software and the Bitcoin network officially began. I should also mention that the smallest unit of a Bitcoin is called a Satoshi. 1 BTC = 100,000,000 Satoshis. When purchasing Bitcoin, you don’t actually need to purchase an entire coin. Bitcoin is divisible, so you can purchase any amount greater than 1 Satoshi (0.00000001 BTC).
What Is Blockchain?
Blockchain is a distributed ledger, a distributed collection of accounts. What is being accounted for depends on the use-case of the blockchain itself. In the case of Bitcoin, what is being accounted for is financial transactions. The first block in a blockchain is referred to as the genesis block. A block is an aggregate of data. Blocks are also discovered through a process known as mining (more on this later). Each block is cryptographically signed by the previous block in the chain and visualizing this would look something akin to a chain of blocks, hence the term, blockchain. For more information regarding blockchain I’ve provided more resouces below:
Bitcoin mining is one solution to the double spend problem. Bitcoin mining is how transactions are placed into blocks and added onto the blockchain. This is done to ensure proof of work, where computational power is staked in order to solve what is essentially a puzzle. If you solve the puzzle correctly, you are rewarded Bitcoin in the form of transaction fees, and the predetermined block reward. The Bitcoin given during a block reward is also the only way new Bitcoin can be introduced into the economy. With a halving event occurring roughly every 4 years, it is estimated that the last Bitcoin block will be mined in the year 2,140. (See What is Block Reward below for more info). Mining is one of those aspects of Bitcoin that can get extremely technical and more complicated the further down the rabbit hole you go. An entire website could be created (and many have) dedicated solely to information regarding Bitcoin mining. The small paragraph above is meant to briefly expose you to the function of mining and the role it plays within the ecosystem. It doesn’t even scratch the surface regarding the topic.
How do you Purchase Bitcoin?
The most popular way to purchase Bitcoin through is through an online exchange where you trade fiat (your national currency) for Bitcoin. Popular exchanges include:
There’s tons of different exchanges. Just make sure you find one that supports your national currency.
Bitcoin and cryptocurrencies are EXTREMELY volatile. Swings of 30% or more within a few days is not unheard of. Understand that there is always inherent risks with any investment. Cryptocurrencies especially. Only invest what you’re willing to lose.
Transaction & Network Fees
Transacting on the Bitcoin network is not free. Every purchase or transfer of Bitcoin will cost X amount of BTC depending on how congested the network is. These fees are given to miners as apart of the block reward. Late 2017 when Bitcoin got up to $20,000USD, the average network fee was ~$50. Currently, at the time of writing this, the average network fee is $1.46. This data is available in real-time on BitInfoCharts.
In this new era of money, there is no central bank or government you can go to in need of assistance. This means the responsibility of your money falls 100% into your hands. That being said, the security regarding your cryptocurrency should be impeccable. The anonymity provided by cryptocurrencies alone makes you a valuable target to hackers and scammers. Below I’ve detailed out best practices regarding securing your cryptocurrency.
Two-Factor Authentication (2FA)
Two-factor authentication is a second way of authenticating your identity upon signing in to an account. Most cryptocurrency related software/websites will offer or require some form of 2FA. Upon creation of any crypto-related account find the Security section and enable 2FA.
The most basic form of 2FA which you are probably most familiar with. This form of authentication sends a text message to your smartphone with a special code that will allow access to your account upon entry. Note that this is not the safest form of 2FA as you may still be vulnerable to what is known as a SIM swap attack. SIM swapping is a social engineering method in which an attacker will call up your phone carrier, impersonating you, in attempt to re-activate your SIM card on his/her device. Once the attacker has access to your SIM card he/she now has access to your text messages which can then be used to access your online accounts. You can prevent this by using an authenticator such as Google Authenticator.
The use of an authenticator is the safest form of 2FA. An authenticator is installed on a seperate device and enabling it requires you input an ever changing six digit code in order to access your account. I recommend using Google Authenticator. If a website has the option to enable an authenticator, it will give you a QR code and secret key. Use Google Authenticator to scan the QR code. The secret key consists of a random string of numbers and letters. Write this down on a seperate sheet of paper and do not store it on a digital device. Once Google Authenticator has been enabled, every time you sign into your account, you will have to input a six-digit code that looks similar to this. If you happen to lose or damage the device you have Google Authenticator installed on, you will be locked out of your account UNLESS you have access to the secret key (which you should have written down).
A wallet is what you store Bitcoin and cryptocurrency on. I’ll provide resources on the different type of wallets later but I want to emphasize the use of a hardware wallet (aka cold storage). Hardware wallets are the safest way of storing cryptocurrency because it allows for your crypto to be kept offline in a physical device. After purchasing crypto via an exchange, I recommend transferring it to cold storage. The most popular hardware wallets include the Ledger Nano S, and Trezor. Hardware wallets come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key as well as any other sensitive information in a safety deposit box. I know this all may seem a bit manic, but it is important you take the necessary security precautions in order to ensure the safety & longevity of your cryptocurrency.
Technical Aspects of Bitcoin
Address: What you send Bitcoin to.
Wallet: Where you store your Bitcoin
Max Supply: 21 million
Block Time: ~10 minutes
Block Size: 1-2 MB
Block Reward: BTC reward received from mining.
What is a Bitcoin Address?
A Bitcoin address is what you send Bitcoin to. If you want to receive Bitcoin you’d give someone your Bitcoin address. Think of a Bitcoin address as an email address for money.
What is a Bitcoin Wallet?
As the title implies, a Bitcoin wallet is anything that can store Bitcoin. There are many different types of wallets including paper wallets, software wallets and hardware wallets. It is generally advised NOT to keep cryptocurrency on an exchange, as exchanges are prone to hacks (see Mt. Gox hack). My preferred method of storing cryptocurrency is using a hardware wallet such as the Ledger Nano S or Trezor. These allow you to keep your crypto offline in physical form and as a result, much more safe from hacks. Paper wallets also allow for this but have less functionality in my opinion. After I make crypto purchases, I transfer it to my Ledger Nano S and keep that in a safe at home. Hardware wallets also come with a special key so that if it gets lost or damaged, you can recover your crypto. I recommend keeping your recovery key in a safety deposit box.
What is Bitcoins Max Supply?
The max supply of Bitcoin is 21 million. The only way new Bitcoins can be introduced into the economy are through block rewards which are given after successfully mining a block (more on this later).
What is Bitcoins Block Time?
The average time in which blocks are created is called block time. For Bitcoin, the block time is ~10 minutes, meaning, 10 minutes is the minimum amount of time it will take for a Bitcoin transaction to be processed. Note that transactions on the Bitcoin network can take much longer depending on how congested the network is. Having to wait a few hours or even a few days in some instances for a transaction to clear is not unheard of. Other cryptocurrencies will have different block times. For example, Ethereum has a block time of ~15 seconds. For more information on how block time works, Prabath Siriwardena has a good block post on this subject which can be found here.
What is Bitcoins Block Size?
There is a limit to how large blocks can be. In the early days of Bitcoin, the block size was 36MB, but in 2010 this was reduced to 1 MB in order to prevent distributed denial of service attacks (DDoS), spam, and other malicious use on the blockchain. Nowadays, blocks are routinely in excess of 1MB, with the largest to date being somewhere around 2.1 MB. There is much debate amongst the community on whether or not to increase Bitcoin’s block size limit to account for ever-increasing network demand. A larger block size would allow for more transactions to be processed. The con argument to this is that decentralization would be at risk as mining would become more centralized. As a result of this debate, on August 1, 2017, Bitcoin underwent a hard-fork and Bitcoin Cash was created which has a block size limit of 8 MB. Note that these are two completely different blockchains and sending Bitcoin to a Bitcoin Cash wallet (or vice versa) will result in a failed transaction. Update: As of May 15th, 2018 Bitcoin Cash underwent another hard fork and the block size has increased to 32 MB. On the topic of Bitcoin vs Bitcoin Cash and which cryptocurrency is better, I’ll let you do your own research and make that decision for yourself. It is good to know that this is a debated topic within the community and example of the politics that manifest within the space. Now if you see community members arguing about this topic, you’ll at least have a bit of background to the issue.
What is Block Reward?
Block reward is the BTC you receive after discovering a block. Blocks are discovered through a process called mining. The only way new BTC can be added to the economy is through block rewards and the block reward is halved every 210,000 blocks (approximately every 4 years). Halving events are done to limit the supply of Bitcoin. At the inception of Bitcoin, the block reward was 50BTC. At the time of writing this, the block reward is 12.5BTC. Halving events will continue to occur until the amount of new Bitcoin introduced into the economy becomes less than 1 Satoshi. This is expected to happen around the year 2,140. All 21 million Bitcoins will have been mined. Once all Bitcoins have been mined, the block reward will only consist of transaction fees.
Any computer that connects to the Bitcoin network is called a node. Nodes that fully verify all of the rules of Bitcoin are called full nodes.
In other words, full nodes are what verify the Bitcoin blockchain and they play a crucial role in maintaining the decentralized network. Full nodes store the entirety of the blockchain and validate transactions. Anyone can participate in the Bitcoin network and run a full node. Bitcoin.org has information on how to set up a full node. Running a full node also gives you wallet capabilities and the ability to query the blockchain. For more information on Bitcoin nodes, see Andreas Antonopoulos’s Q&A on the role of nodes.
What is a Fork?
A fork is a divergence in a blockchain. Since Bitcoin is a peer-to-peer network, there’s an overall set of rules (protocol) in which participants within the network must abide by. These rules are put in place to form network consensus. Forks occur when implementations must be made to the blockchain or if there is disagreement amongst the network on how consensus should be achieved.
Soft Fork vs Hard Fork
The difference between soft and hard forks lies in compatibility. Soft forks are backwards compatible, hard forks are not. Think of soft forks as software upgrades to the blockchain, whereas hard forks are a software upgrade that warrant a completely new blockchain. During a soft fork, miners and nodes upgrade their software to support new consensus rules. Nodes that do not upgrade will still accept the new blockchain. Examples of Bitcoin soft forks include:
A hard fork can be thought of as the creation of a new blockchain that X percentage of the community decides to migrate too. During a hard fork, miners and nodes upgrade their software to support new consensus rules, Nodes that do not upgrade are invalid and cannot accept the new blockchain. Examples of Bitcoin hard forks include:
Note that these are completely different blockchains and independent from the Bitcoin blockchain. If you try to send Bitcoin to one of these blockchains, the transaction will fail.
A Case For Bitcoin in a World of Centralization
Our current financial system is centralized, which means the ledger(s) that operate within this centralized system are subjugated to control, manipulation, fraud, and many other negative aspects that come with this system. There are also pros that come with a centralized system, such as the ability to swiftly make decisions. However, at some point, the cons outweigh the pros, and change is needed. What makes Bitcoin so special as opposed to our current financial system is that Bitcoin allows for the decentralized transfer of money. Not one person owns the Bitcoin network, everybody does. Not one person controls Bitcoin, everybody does. A decentralized system in theory removes much of the baggage that comes with a centralized system. Not to say the Bitcoin network doesn’t have its problems (wink wink it does), and there’s much debate amongst the community as to how to go about solving these issues. But even tiny steps are significant steps in the world of blockchain, and I believe Bitcoin will ultimately help to democratize our financial system, whether or not you believe it is here to stay for good.
Well that was a lot of words… Anyways I hope this guide was beneficial, especially to you crypto newbies out there. You may have come into this realm not expecting there to be an abundance of information to learn about. I know I didn’t. Bitcoin is only the tip of the iceberg, but now that you have a fundamental understanding of Bitcoin, learning about other cryptocurrencies such as Litecoin, and Ethereum will come more naturally. Feel free to ask questions below! I’m sure either the community or myself would be happy to answer your questions. Thanks for reading!
Dear NEO Health Community: Firstly, I would like to thank everyone for your support since we opened the PeerAtlas Telegram last November. We are all in this together. I will provide a brief history of PeerAtlas and NEO Health. 2011: The PeerAtlas project begins with the goal of launching a completely free library for high-quality medical information, and ultimately launch a live rolling clinical trial to collect outcome data on patients, which would prove or disprove the claims of pharmaceutical companies, becoming the most valuable medical database in the world. 2011-2016: PeerAtlas founder Brad Mattson codes an alpha version of a wiki-based medical algorithm encyclopedia while in medical school and training to become a radiologist. Development and marketing of the project is difficult during this time because the majority of Brad's time is consumed by the notoriously brutal schedule of a doctor in training…but the project continues. For those who don't know, doctors enjoy working longer hours than most for reasons that are unknown. November 2016: Brad buys his first Bitcoin, watches the price of Bitcoin increase, and instantly becomes a crypto degenerate (AKA true believer) like several others before him. Brad watches all of his personal holdings get tied up in crypto over the next several months, and considers selling his house. In retrospect, I should have sold the house. April 2017: Brad moves all of his crypto investments into Antshares because he reads on Reddit that Antshares has the best community and he enjoys supporting a Chinese project because his wife is Chinese. This really was all the research I did, but most people would recommend reading the whitepaper before making moves like this. June 2017: Brad hopes to launch PeerAtlas on the platform of the future, and like any self-respecting crypto degenerate (AKA true believer), he believes the future of everything must be blockchain. Having so much respect for the strength of the Antshares community, Brad asks his wife and PeerAtlas co-founder, Ling Wu, to email Antshares founder, Da Hongfei. Da replies and talks to launch an ICO on Antshares begin. July 2017: Antshares rebrands to NEO. PeerAtlas co-founder Colin Closser completes the first draft of the PeerAtlas whitepaper. Early November 2017: The PeerAtlas team (Brad Mattson, Ling Wu, and Colin Closser) visits NEO headquarters in Shanghai and plans the launch of the PeerAtlas ICO. Mid November 2017: The PeerAtlas Telegram is opened. Late November 2017: Cryptocurrency markets and altcoins begin their climb to new all-time highs. December 2017: The PeerAtlas project is presented at the NEO meetup in New York City. Cryptocurrency markets are out of control. The PeerAtlas Telegram begins daily quizzes with gas awards for first 10 winners. The quizzes take place for almost 5 months, with special thanks to Vivek, Raj, Melicio and several other members of the community for making this possible. PeerAtlas co-founder Ling Wu with NEO founder Da Hongfei at the NEO meetup in New York City Early January 2018: The PeerAtlas ICO page goes live. Cryptocurrency markets remain out of control. The SEC sets a date for early February to discuss ICOs, security tokens, and utility tokens. Obviously this means bad news for US-based ICOs. Late January 2018: The PeerAtlas project is presented at the first-ever NEO DevCon in San Francisco. February 2018: The SEC declares that all utility tokens are in fact security tokens. The PeerAtlas team consults dozens of lawyers for advice regarding the launch of a US-based ICO, and we get a different answer from every lawyer because nobody has any idea what's going on. PeerAtlas suspends plans to launch an ICO from the US against the advice of several lawyers who claim the SEC doesn't have the resources to investigate every single ICO. As it turns out, the SEC does have the resources to do this, and we watched several projects get shut down by the SEC. March 2018: Cryptocurrency markets are not looking so great. The PeerAtlas team researches launching the project from a crypto-friendly country outside of the US. Research leads to Gibraltar, Liechtenstein, Malta, and Switzerland as possible options. April 2018: Cryptocurrency markets are looking worse. The word on the streets is that Binance, the world's largest exchange, will be moving to Malta and the PeerAtlas team decides that wherever Binance is going is probably also where we should go. Legal negotiations begin in Malta and PeerAtlas officially becomes a Malta-based company. Late April 2018: Cryptocurrency markets are still taking a dive, but PeerAtlas moves forward with plans to launch the token sale in May. Early May 2018: Cryptocurrency markets still look terrible but are beginning to become more stable. PeerAtlas launches the presale on May 1st. Three days after the presale is launched Brad is contacted by iScientia (www.iscientia.com) founders Koen Vanneste and Laurent David to form a partnership. Brad recognizes that iScientia is a European leader in medical information and clinical decision support for almost 20 years with endorsements from the most well-respected medical journals and libraries, and accepts the partnership. Mid May 2018: The PeerAtlas token sale is suspended while the goals of the project are updated after the partnership with iScientia. The project takes on a new direction with a drastically more ambitious scope. June 2018: PeerAtlas and iScientia merge to form NEO Health, and begin building a completely web-based electronic medical record to integrate with the iScientia clinical decision support tool and digital health library which is currently operating in several European countries. July 2018: Brad suspends his career as a radiologist and moves to Belgium to work on the project full time with iScientia. Recent Events: In what will go down as one of the most interesting experiences of my life, I traveled to Milan, Italy with iScientia co-founders Koen Vanneste and Laurent David where we had arranged a meeting with “investors”. We were asked to meet the “investors” in a coffee shop/bookstore outside of Milan. We waited in the bookstore for around 45 minutes before the “investors” finally showed up, one dressed normally and the other dressed in a full Giorgio Armani suit. The one dressed normally was carrying a large black bag. They treated us to a cup of coffee and discussed investing into our presale. They suggested that we take 2 million euro in cash from them and put it in the trunk of a rented car and drive it across several country borders back to Belgium, and then call it their investment in our project LOL. They asked if we could meet again the next day in an undisclosed location to finalize the deal, and asked us to bring a money counter with us the next time we meet. Does it look like I just fly in from New York and I'm carrying a money counter in my backpack? If I ever need to use a money counter for anything I'm going to get one of those green banker visors to go with it. The next day the location of the meeting changed five times before we finally agreed to meet at a very shady restaurant like something you would see in a Martin Scorsese film. At this point I figured this must be someone's idea of a practical joke. They bought us a pretty nice dinner which was definitely appreciated, but we did not have a money counter and no money exchanged hands. I explained that we were thankful for their offer, but we simply cannot accept 2 million euro in cash, put it in the trunk of a rented car, and drive it back to Belgium LOL. The story actually gets more crazy, but to protect people's privacy and make sure we don't end up getting shot, I'm not going to go into more detail. For the record, NO CASH WAS ACCEPTED FROM ANYONE. Over the past two weeks we have been quite busy beginning development of a completely web-based electronic medical record which we will integrate with the digital health library and clinical decision support tool from iScientia to provide doctors with clinical decision support at the point of care through the NEO Health EMR. We are also finishing the new whitepaper and building an ICO page. NEO Health headquarters in Belgium, at the European Center for Implementation of Evidence-Based Guidelines In addition, we met with Nigerian government officials and are hoping to deploy our software in Nigeria if we can come to an agreement. Nigeria would be an ideal place to launch NEO Health because there is less barrier to entry than in the United States or Europe where there are endless healthcare regulations and patient privacy laws. We feel the quality and access to healthcare in Nigeria would improve tremendously if doctors were using a modern electronic medical record system as opposed to paper charting which is currently the most common form of charting in Nigeria. We will also speak with select hospitals in China which will serve as test sites for NEO Health, before expanding further into China. Thank you sincerely to the NEO Health community for your support! I will keep you updated with a weekly, or at most a bi-weekly newsletter. Best Regards, Brad Mattson MD Founder of NEO Health https://preview.redd.it/atfit1r3cqf11.png?width=133&format=png&auto=webp&s=b1077898e618e4dabd9efcf6cb02510b9c4f98d8
Cryptopia CEO Alan Booth on the Cryptocurrency Exchange Realm (Full Article No Link)
Alan Booth is the CEO of one of Cryptopia, an exchange regarded as having one of the widest selection of tokens. Founded in 2014, Cryptopia is one of a handful of blockchain-focused companies in New Zealand. The Cryptopia team is often tasked with researching hundreds of projects to determine their efficacy before any other major exchange has touched them. The exchange lists many projects in their early stages and post-ICO. As an entrepreneur and business consultant for over 50 years, Alan Booth’s story is fairly atypical of that of many entrepreneurs in the cryptocurrency world. His perspective on the cryptocurrency is grounded in decades of business development experience, and he views the cryptocurrency exchange realm as one of the most exciting opportunities yet. In the following interview, we dive into everything from cryptocurrency psychology, the coin listing process, and blockchain entrepreneurship. How did you get introduced into the crypto world? That’s interesting. I was consulting for Cryptopia or consulting to assist them in their development path for several months when it became obvious that they needed some senior leadership to move them from where they are, which was basically a reactive technical focus to a more business global focus on how we develop their business model. We are very conscious of the fact that you need a higher level of thinking. You need a global perspective, particularly from New Zealand because there’s not a lot of us down here. That probably predicates why we’re a global business grown out of such a small population. We’d known each other for a while, certainly six months or so, and when the opportunity came up, why wouldn’t I move from a very safe, comfortable, fun job that I had previously, which was the chief executive of an international flying school. Nothing really scary goes on there. I am at the latter end of my working life, somewhat semi-retired and all my colleagues went, “You’re going to do what? Are you kidding?” Of course, the blood pressure went up and I said, “yeah, I’m going to have a go at this.” So, it’s really about the opportunity when you’ve learned so much over 40 or 50 years of developing business models and floating companies and taking them to the world, which is primarily what I’ve done. To find something that’s new and a full of excitement and fear and trepidation and where is all this going? Then it’s an opportunity you can’t afford to pass up. So, it’s just the daredevil saying let’s go. The risk and the general fervor for the industry have gotten a lot of people very excited. What are the top concerns for exchanges moving forward from your perspective? They are many fold and they are variable based on feedback from the community and somewhat driven by legislation, driven by corporate requirements. The FinTech world, we’ve got to look at that as well as the coin world. If we want to grow and deliver a product that the average consumer can consume, then we have to deliver all the things that they would typically expect. So, if you went into a retail store to buy a heater, you expect to have a warranty. You expect to be safe, you expect to be treated well with clarity. And typically, the coin industry to date has not been very good at that because it’s been evolving and mostly evolving from a technical perspective with probably less weight put on the public consumption of the coin. It’s being technically driven as a technical product when you look at it. When you go to the exchange, some of them take a fair bit of thinking about before you can operate. So, for us, the first thing is trust. If people can’t trust your brand, and that means every part of it, you’re not going to succeed. So, we are very proactive here in New Zealand, talking to legislators, government agencies in and out of New Zealand. KYC, AML, CML, all of that stuff. We are drafting our own internal rules and then most cases they exceed the requirements of our banking partners. So, they look at us and they go, wow, you’re way ahead of where we thought it would be. So, developing a trust relationship with our consumers and business partners is vital. The next thing is developing a stable and functional platform. I don’t just mean the coin exchange itself, but all of the underlying technology. Will we be up? Do we have latency? Are we speedy? Have we purchased the right partnership relationships for our equipment and how do we continue to be able to scale at will and not risk failing to deliver a result? That means helping people get an exchange done, their coins on and off. I suspect it’s the same as every other exchange. Only thing is, down here, we have really focused on three things to move us very quickly forward. One is the public-facing components. That’s the help desk if you get stuck. We want to be able to respond very quickly. And like the other exchanges, we headed enormous influx in the early part of the year and that was debilitating. Nobody was ready for it. We employed teams of people to come in and train as support operators. We’ve since then spent a huge amount of money on a new ticketing system, which actually went live yesterday. So, this morning when I come in, there’s smiley faces trying to get their head around it going, wow, this is amazing. So, we triage all the tickets on the inbound route now and puts it in a good space for our response team to reply as quickly as possible, I want. At the moment, we’re not there. Instead of being 40 or 50 hours and all these horrible delays, I want people to have a response from us immediately and I mean within seconds saying we’ve got your ticket. I can’t answer it right now, but we’re on you. Then, within hours, get back to those customers and fix their problem. They don’t deserve to wait 24 hours or 48 hours. People are anxious. Ticketing, we’ve done something about it. Highly trained staff, we’re employing all the time. We’ve developed foreign offices to beat the time zone thing. We now have a support office in the UK that we have had for some time, actually. The next thing is just the stabilizing of our software and hardware. When you start these things, the enthusiasm and the inexperience of the development team may not know what’s here to them and now we’ve bought in bigger, stronger, international teams. So, that’s great what you’ve got, but let’s do this. So, that’s the phase we’re on now. We’re spending all of our money. In fact, every penny that we generate in this business goes straight back into furthering and developing the products. Nobody’s racing home in Lamborghinis or flying their jets around. They’re just piling into it. So, that’s how I am in terms of producing a high-quality product. It’s not a decision we just made. It’s always been there, but we are now articulating it internally, that we want to be in the top five of crypto exchanges and digital asset exchanges of some form within the next two years. In the top five, bar none, in every respect. Would you say the number one component of being thought of as one of the top five would be trading volume? Is that the primary metric? I absolutely agree with you, but you can’t have trading volume unless you provide the other things first, like security, safety, a good trading platform. If you want trading volume, I have to have a reason for you to trust me, which has to be if I have a failure, will my ticket, be answered? If you do those things, you will get trading volume. I don’t believe you look at it the other way and say, hey, let’s create trading volume because if that comes at you hard and sharp, how are you going to cope with it when something breaks? It’s technology, things will break. It’s how you address things that go wrong that made you successful, not what you put in place to drive that business in. That will happen if you’re good. The word gets out saying this is a great exchange. They fixed my tickets, they’re fast, they’re responsive, it’s safe. That will create trading volume. Trading volume for us is income and of course, we want it. We have actually slowed down on coin listings. We’ve slowed down on taking new customers and we’ve slowed down on developing relationships with partners simply to get our platform in better shape so that we can become the most reliable, trusted partner you can have. That will create trading volume, no doubt about it. Although trading volume does bring in a sizable amount of revenue, there comes a point where it just becomes a vanity metric where people are using an exchange simply because there just aren’t any better alternatives out there.. So, if there is an exchange that can offer all the features that you’re talking about and a premium level of service, then the trading volume will trickle down. There’s no real loyalty for exchanges other than preferences. Absolutely. We wouldn’t ask for that. Why would you say to somebody, hey, you got to be loyal to us? That’s just silly. You will be loyal to us if I offer you a great experience. That means volume of coins, a huge range to trade through. Ease of trading. One click, two clicks. How about some trading tools just like you see in a modern foreign exchange opportunity? Some arbitrage tools, some tools for measurement, some nice desktop tools. We want to introduce other things. It just means that you’ve got control over your own reporting and your own desktop environment. It can become a very powerful tool to use as long as we listen to the customers and say, hey guys, we can develop that. Give us a couple of months, let’s put it in front of you. What is the coin listing process for you guys? What’s the process for someone who wants to get their coin listed on Cryptopia? We’re just reviewing that and we’re being very focused on changing the way we list coins and who we list. We’re very conscious to gain trust. We are actually your first port of call for particularly those people who don’t know much about coin, so they have to trust their exchange partner. Therefore, we have to make sure that if we list a coin, it’s a viable trusted, honest coin that’s going to give value. Not just to us as an exchange but it’s not a scam coin. It’s not something just to raise money, pump and dump thing. We have coin listing teams who are very tough. I have introduced people as the CEO to my coin listing team and I can’t get it through them. I’ve said, but these are great guys and I have a great story and I met them in Vancouver and boy, they’ve convinced me. My coin listing technical team does all the due diligence. Everything from GitHub, Facebook pages, normal stuff like that. If it doesn’t look like a viable product to us on many levels, then it doesn’t get listed. That’s the end of it. If [the coin] gets past that, we do further due diligence. We’ll actually interview the company. We’ll ask why do you want to list? Why do you want to list with Cryptopia? What’s your plan for the coin? What do you want us to tell customers because they’re going to be relying on us? So, we’d like to do more than just have a coin called 21 Million sitting on the exchange. How about if we had a link to that with some of the criteria we use to judge whether that was a good opportunity. Whether it was a good coin. We might have a 10-point plan and we might say, hey, this coin passed at 9.7. This coin is in, but it only got in at 2.4. Whereas the negative coins, the coins that have gotten negative plans, negative equity in our mindset, they just don’t get on the exchange. We have a very large number of coins at the moment. We want to remain in that space, be the leader. That means that clearly, we’re not going to get it right all the time because we make mistakes and actually, so do the some of the honest and reliable coin generators. Their plans might not just happen, so they get the benefit of the doubt for a while. As long as we see that they’re not doing something deliberately to disrupt the market or just to take money, then we’ll support them until they get their business model right. But we’re very focused on a coin listing to us is actually a business partnership. We’re not just going to throw coins up there. I think 2018 is the year of reckoning, wherein 2017, pretty much anything got listed anywhere. It didn’t really matter how functional the coin was or whether it was legitimate or not. So, it’s really cool to see the trend in exchanges making a stance against that because if the ax falls, it doesn’t fall on the anonymous coin team that could be in Switzerland and Ethiopia. It’s falling on the CEOs and the exchange teams that are allowing access. People come to us and they say, hey, I haven’t got my money. You’re the exchange. I go, well actually, the coin that we listed, I’m afraid the wallet’s faulty or they didn’t do this, or they ran away. People don’t care. They’re relying on us. That’s why Cryptopia has to be a business partner with each and every user, not just a provider of some coin listings. That would be unethical. Absolutely, and it’s good to hear. Speaking of regulations, how do you think that’s going to evolve for exchanges, especially being out of New Zealand? I welcome a regulatory intervention for many reasons. The primary one is that as soon as the regulators start imposing their will and taking notice, it means that it’s a genuine opportunity. They don’t waste their time on something that’s not going to affect global economies or our economy. For example, the New Zealand regulators, we’re working and we’re working with them because they recognize that somebody has got to work with them to tell them what’s going on. The other side of the fence, that’s us. We have to work with them to say, you can’t do that because it won’t work in this environment. So, working with regulators is critical, in my opinion, and we’re doing that very well. Regulation has to come. It was just announced in New Zealand a few days ago that we’re going to start, this is unrelated to coins, collecting GST, which is our equivalent of your local taxes, on online purchases. So, typically anything up to $400 that you buy online from Amazon, for example, in New Zealand, you wouldn’t pay tax on and they’re changing that. They’re taking the same view with coins. So, the government is saying, how do we tax revenue? When do we tax revenue? What should it look like? How do we make it fair for you, the exchange and how do we make it fair and manageable by the consumers who may have to declare a capital gain if they’re going, for instance, as an equity or a property as pure speculative fun like betting? And if that’s the case, when should we do this? Should we backdate all that stuff? Every country is going through this and some have jumped in and made decisions that they’ve had to backpedal on. They were a little bit hasty. In New Zealand, in particular, we have a great relationship with the regulators and all the powers that be, right down to the banks, and are all looking at the space saying, you know what? We don’t quite know what to do, but let’s start doing something and I welcome it. And the more understanding and control we have on these things at this early stage these next few years, the neater and cleaner will be over the next few years. Just as banking has become very stabilized through regulations, so will this crypto business, whatever it ends up looking like. New Zealand has its advantages because a smaller population could make building direct relationships with regulating authorities easier. Tim Draper, for example, is investing in Papua New Guinea to try and make this whole digital citizenship country. The Binance guys just moved over to Malta. The global landscape just opened up, and governments will have to start offering distinct advantages to attract companies that could hypothetically set up virtually anywhere. That’s great because that’s exactly what online trading is about. It’s online and it’s global. We have to join the global party, but we better start from a position of understanding and strength in our own environment. Make sure we have our own stuff together before we start yelling about what someone else should do. Yeah, absolutely. Shifting gears a little bit, what do you think about decentralized exchanges and how they’re going to affect the whole exchange thing? The quick and easy answer to that is it will definitely affect the global exchange market. It will definitely affect FinTech because if people who are regular investors and that’s people with mom and pops with a few dollars, right up to institutional investors, if they can see a way of generating revenue and it’s safe, they’re going to move there. They’re not going to discard their other investment opportunities and they’re not going to discard regular exchange-traded equities or working on the stock exchange. But there’s a space here that we haven’t quite worked out who that’s going to work for or how, but the more we regulate, the more we make the tools visible. The stronger we look to the market and the more professional we look. That doesn’t necessarily mean just wearing a suit into a meeting, but the more gravitas we have behind those discussions demonstrating that we’ve done on the work and that we’ve got smart people here and the technology’s good. We’re ready to come and meet and talk equitably to investors and traditional investment houses. Then there will be a way that they join up. There’s no doubt about it. I mean, it can’t be helped. How about the lightning network and atomic swaps where you could pretty much exchange peer to peer. You could trade Litecoin for Ethereum directly in one single transaction without an exchange. Centralized exchanges have their benefits, like for example, there’s someone you can knock on their door and say where’d my money go? I need customer support. So, there are advantages there, but then the advantages of a decentralized exchange are just the efficiency. I’m wondering how is that viewed for the centralized exchange world? I don’t want people to take away my income opportunity. We’re building a business. We would argue, and I think it could be demonstrated to date until the blockchain comes up with some technical solutions. We’re building a trust environment and we are taking on, at considerable cost, the responsibility for providing the trust. First, it’s a coin that we like and here are the reasons. We’ve done the due diligence on your behalf. We allow the transactions to take place and here’s how we regulate, manage and deliver that transaction and manage the wallet relationships. Cryptopia’s Coin Information display That’s a role we take on. So, if you trade with a centralized exchange, you’ve got a whole lot of advantages that you don’t have by trading peer to peer. It’s fairly obvious what a peer to peer relationship looks like. If that’s on a personal level, that risk is much greater. If it’s on a more corporate structured level, I don’t know what that looks like yet, but I think we’ve got a long way to go before we could move from centralized exchanges to peer to peer simply because there’s going to have to be some regulation around it. How would the regulators engage in that space? Who are they engaging with? Every single person who wants to trade? At the moment, they can deal with an exchange that has potentially 2,000,000 to 10,000,000 customers. That’s not easy for a regulator or a tax authority. So, there’s the regular regulatory component. That’s got to be there. Then there’s the trust management and then there are just a few more technical issues that I think have yet to evolve. It all comes down to running a business. It takes money and capital to get all these users you want to get. If the technology works, that’s great, but onboarding users take resources. How do these projects plan on doing that? It’s just a missing component of every single white paper that tries to go after that who isn’t trying to build a centralized business to oversee it. I think philanthropy is wonderful and when people are talking about decentralization. It’s a great idea and it’s philanthropic and it would be wonderful if the world could work like that. But there’s never been a business model that has worked without generating revenue. There isn’t one. Everyone’s tried, but you can’t name one that doesn’t have to generate revenue at some point or another. Even if that revenue is simply generated to make the action happen, the hardware, the software, the bandwidth, someone’s got to pay. So, if you’re decentralizing, how do you get paid? How do you police it? How do you manage it? Why not stick to a model that works? And it’s not just about centralized coin exchanges. It’s not just about front-end institutions. This is a model that’s worked since the first inhabitants of Earth swapped a bean for a stick or can I give you my dinosaur to cook while I bring you a giraffe? I don’t know, but you can’t have a society without an exchange happening of some value in exchange. Even if I go to a coffee bar with you, here’s the simplest thing. I would say, hey, I’ll meet you for coffee, on me I might pay for the coffee, but guess what? We’ve sat down and exchanged information. I’ve gotten something out of it. How do you do stuff without exchanging value? It’s push and pull between advancing technology and proving the model works but then what’s the incentive to run it and popularize it because you’ve got that whole chicken and egg problem. We need a bunch of users for this to work efficiently, but we’re not going to make any money doing it. Hopefully, we’ll see how things play out in the next couple of months or years or decades. I’m down for decades and a lot of failures. We’ll be there watching them saying we’ll help you if we can and hey, go and play guys, but come back here when it doesn’t work because we are going to be here. What are your thoughts on Bitcoin dominance in general compared to all the other coins out in 2018? So, what does a cryptocurrency landscape look like if Bitcoin happens to fall down to, let’s say, 15\% or 10\% of the market? Does Bitcoin really dominate or is it just big? If you look at the exchanges and watch the traffic, can you see as much traffic taking place and as much interest in the CoinCash or 21 Million or Kenya or any of these things? They’re all there and people are trading them for various reasons. Mom and pops are going to be doing this to buy a new car. Someone else purely looking as a store of wealth and other people are looking to dominate a market. So, I’m not sure that you could say Bitcoin dominates. It might be the largest store of wealth at the moment. Does it dominate people’s thinking? I’m not sure about that. If you’re a coin developer, it’s your coin that’s dominant in your mind and you’ll go after a particular vertical, even a geographic market. So, you have the potential to develop your store or your story within that business scope. Why does Bitcoin dominate? Simply because it was seen as an opportunity? Is it dominated because the people who trade in Bitcoin put so much faith in it being a store of wealth or an opportunity for capital gain? But a lot of those people have run away. That’s why it’s not $20,000 at the moment. It’s just trading between 8,000 and 10,000 in there. So, it stabilized. So, what if it fell over? Some people will lose money. It’s not going to change the blockchain, it’s not going to change our thinking about cryptocurrencies. It’s not going to change Cryptopia’s approach to the market. It might dominate in volume. I’m not sure it’s the dominant force supporting cryptocurrencies. I see what you’re saying. It might just be a dominance of user acquisition because there’s a larger chance they heard of Bitcoin instead of Ethereum if they have heard of cryptocurrency at all. So, it’s like the gateway crypto. Take care that people aren’t saying Bitcoin just like a Hoover, the vacuum cleaner. Every vacuum cleaner for 20 years was called a Hoover. That was the dominant brand. Hey, I’m going to Hoover the floor. What they meant was I’m going to get my vacuum cleaner of which there are 80,000 different makes out there now and they’re going to vacuum the floor, but they just called it a Hoover. So, I trade in Bitcoin. I’ll bet you someone who says, yeah, I trade Bitcoin, he’s only saying bitcoin because he knows or she knows that people understand that you’re referring to a cryptocurrency. If you say to someone I trade in Clearpoll or CoinMedic3, they have no clue what you’re talking about. They go what is that? Oh, it’s Bitcoin. Oh, I get it. If you went home to your mom and dad and they asked what are you doing? You’d say, oh yeah, I’m trading cryptocurrency. They’d go, oh? What’s what? You’d go, Bitcoin. They go, oh, that thing. Bitcoin Cash is competing to be known as the Bitcoin for a reason. In the next four or five years, there are millions of people that haven’t even heard of crypto that would probably receive a lot of benefits from being onboarded into the cryptocurrency world. I’m not really sure how what they get onboarded to first matters immediately, but I know it plays a substantial role for a lot of people. It’s an initiator. It’s a keyword that attracts them to the space that we’re in. It’s simply because it’s got brand dominance in the public persona. If you say a Bitcoin, most people know you’re talking about that strange online thing that no one understands and there are a few other coins, but we don’t know what their name is. As soon as they hit an exchange, if they really want to try it, they’re going to look at the next one down and say oh, I didn’t know that existed. They’ll make their way right to the bottom of the 2,000 list. So, I really don’t think we should worry too much about dominance or anything that’s measured in that way in the space because the variables that change our value perception on any of these products is a mystery to everyone. A rumor can cause change overnight and things like that have happened. Guess what? They also happen in traditional exchanges. Go to the London stock exchange and you’ll see a piece in the paper tomorrow that prices rocketed or have fallen over the next day because the public is there. The public is there late, remember. If you see it in the news, it has already happened. That’s the same thing for this. So, what are your favorite projects out right now? It has to be blockchain focused. I mean, coins seem to be a tool that are being used to raise capital, raise awareness, create hysteria over or some fun. Some of them, and I believe it’s very few of them, I wouldn’t like to statistically put a number on that, but I think it’s very, very few have actually got a basis of a typical good investment. Is company strong behind it? Do they have good ethics? Why are they doing this? What’s it for? Or is it just to raise money? When they’ve got money they can go, oh, look how much money we’ve got. Let’s do something. That’s not the way to grow a business. Somebody has to have a good story that’s technically supported. It has to have social value these days. And that means is it good for mankind? Is it going to save the planet? Will it do something? Create manufacturing? Whatever it is. Hey, I’m not a philanthropist. I’m not saying you’ve got to do something to save the planet. But the youth of today are much more conscious about anything we/they do is about social conscience and social values and responsibility. So, for me, any of those projects, whether they be blockchain based or coin based that do something more than just making money for a bunch of guys, so they can go buy a Lamborghini, gets more of a look and support from us than the others. There are ways of going and creating wealth for yourself than preying on opportunities that exist simply because exchanges listed them. So, we’re very careful about that. So, I wouldn’t like to say at this stage, we have anyone in particular. We do have some businesses we’re looking at, but they all are very well rounded in terms of their sales pitch. It’s ethical, it’s got a good background. They have strong management, a history. They’re well-funded already. They’re not just grabbing money to then decide what they’ll do with it. Well said. The one point you made about how these projects need to be ethical and how that impacts those business models because again, you tap into to the same vein of projects that are looking to substantially change industries that had been stifled by inefficiencies or corruption. It stretches a long way. If you find a solution that bugs business and usually if it bugs a business, it bugs and effects people, consumers, in some way. That might just be, where it’s blockchain related, securities and tracking things to make this whole trust environment that we live in. The point is we say we can trust but we can’t trust. Everything we do is about trust. We get lawyers to look after our trust issues and we shake hands and we still wonder whether it’s a deal. So, solving trust issues globally is probably one of the biggest benefits to mankind because once we solve the trust issue, you can then be positive or confident that something that you want to happen and agreed to happen is actually going to happen. If it doesn’t happen, it’s not just about the broken trust. It’s then about the finances involved before you got there. That’s all gone. The future has all gone around that business model. So, trust management in blockchain and around coins and around exchanges, decentralized exchanges, is probably the biggest thing we have to deal with. Which takes me back to my core development program right now, which is developing a trustworthy exchange. Make it clear, unambiguous. Make it reliable, deliver what we said we were going to do. What does a day in the life of Alan Booth look like? What do you do for fun when you’re not doing exchange type things? If there’s even time for fun. If you’re running an exchange, it’s 26 hours a day to run an exchange. If you can squeeze another hour in, you might find some fun. This is probably my last employment opportunity. I’m in my 60’s. I’ve spent 50 years being an entrepreneur and an arm waver. Wave your arms and see who’s taking notice and make something happen. So, fun for me is actually the exploitation of a business opportunity. I go to bed hoping that I wake up in the night with an idea to scribble on the pad. I come to work a very early. I’m up at 5 am. I get here at 7 am if I can with the work already done. I don’t want to arrive at work and look at emails. If you’re looking at email and other stuff, it’s other people’s requests on your time. I’m going to arrive here being creative. I want to arrive every day going, I’ve got nothing to do except be creative and compel all of my employees and partners to support that creativity and bring their own creativity to it. So, you couldn’t have more fun than that, could you? What else is there? Just to make stuff and see people get excited and give them the opportunity. But when I’m outside of this, hey, I liked to fly light aircrafts. I ride fast motorbikes. I do guy stuff, and when I’m not doing guy stuff, I’m at home helping my wife in the garden. Just an ordinary guy. Most of my daylight waking hours is about being that global entrepreneur with regard to this huge global opportunity which is let’s change the world. It’s like moving from coal to steam, steam to mechanization, mechanization to electronics, and now we move into the digital age and we’re in it. What a fantastic place to be. So, how exactly do you do that? Do you just wake up earlier and just get everything done at 5:00 AM? There’s never enough time in the day. What it is, it’s being super critical about what’s actually important. If you open your email when you get to work, I will guarantee that you will sit there procrastinating and jump between emails. Most people don’t work from the top to the bottom or the bottom to the top. You’re a little bit selective, so already you failed to do what people expect you to. Email and inbound inquiry are other people’s expectations of how to use your time. They’re imposing their requirements on you. So, you’ve already allowed yourself to be managed by outside rules. You’ve got to arrive at your office with nothing that interferes with the creative process of why am I at this office? Why did I come here? I came here to understand what we’ve got. So, that’s a constant job. To work with the clever people that you have employed. I have a major role in employment and myself. Only employ smarter people than yourself, only. Because if you’re employing people that aren’t smarter than you, you’re going to have to tell them what to do and you don’t have time for that. Now, employing people smarter than yourself, for me, that sets the bar quite low, that’s easy, so I get really good pickings. But, generally speaking, you need to employ the best people and get them going and then you’ll be so busy running around trying to keep up with him, not them keeping up with you, that you actually have no time for all that outside noise. You’ve got to impose on the world what you want, not the world imposing on you what they want. Turn it around. Every time I have a conversation with somebody, it’s about what I want, in the nicest possible way. We will listen to inbounds but we already have a path to follow. If you start following other people’s paths, you’re not going to get where you want to go. Here’s the thing. I’ve been a business mentor for probably 20 years. Mentoring basically new CEOs. New CEOs, it’s the loneliest job in the world because it might be your first CEO job, so you can’t talk down because those people below you expect you to be the boss, so you can’t ask them. You can’t talk up because you’re the CEO. It’s no good asking the board, they’re looking down at you. You can’t talk sideways because they’re your competitors. So, the first year or two as a new CEO is the loneliest place on the planet. So, what you have to do is be entirely focused on what you need to get done and that is by changing what you used to do before you became a CEO or a boss. What you used to do is respond to every bit of noise that came at you and it filled your day up until you went nutty. Thank you! Cryptopia CEO Alan Booth on the Cryptocurrency Exchange Realm
