So much has happened this week! We saw a capitulation point of bitcoin before bears took over and we saw the selling pressure push Bitcoin down toward the $9000USD mark then move back up above $9100USD So far it has been a stable hold, however we may see some more action within the coming weeks.
Widespread scamming within the Twitter-sphere, Youtube and other platforms as Bitcoin and other cryptocurrencies may seem like fair game. Cryptocurrencies providing big payouts for scammers without the ability for reversals of accounts. Remember if something seems too good to be true, do some research or just plain do not respond/believe it. Stay safe and careful with your funds!
On the brightside, there has been even more adoption of cryptocurrencies as rumours of Paypal utilising cryptocurrency has been confirmed as they are developing crypto capabilities. In addition to this we received exciting news at the start of this week about Binance partnering with Swipe (SXP) and offering a debit card to spend BNB, SXP, BTC and BUSD. ( I will be keeping a swift eye on BNB and Swipe as its utilisation as tokens has just increased 43 fold).
Positive news for the Bitcoin network as its hashrate reaches all time high which helps to secure the network further even though mining profits have dropped by 50% from the recent halving. If you didn't know already the last Bitcoin will be expected to be mined in 2140 with its difficulty ever increasing and each time securing the network further. Processing units will have to become faster, stronger and most importantly more cost effective to continue to entice miners for the block rewards and further renewable energy practices.
Furthermore we can see Central banks and countries discussing and developing Central Bank Digital Currencies (CBDC). Read more about it here https://www.investopedia.com/terms/c/central-bank-digital-currency-cbdc.asp and check out some of the developments in the world above. This shows the popularity and strong nature of cryptocurrencies. As the saying goes "If you cant beat them, JOIN them".
Overall, very solid week full of adoption, animation and anticipation. Another post next week for a weekly round up! See you then but in the mean time join us at our Gravychain Discord.

The attempted come back of CoinEx, China's forked-Bitcoin exchange

The attempted come back of CoinEx, China's forked-Bitcoin exchange
Written by Shuyao Kong
Published by decrypt.co
An interview with Haipo Yang, a crypto OG who’s trying to reposition his Bitcoin Cash-based CoinEx exchange. And more, in this week’s da bing.
https://preview.redd.it/h5f3i3lldv051.jpg?width=3200&format=pjpg&auto=webp&s=09b8696303ae5c6170753cc438929ebe520d4605
Haipo Yang, founder of ViaBTC, one of the largest mining pools in the world, and CoinEx, a crypto exchange known for its focus on Bitcoin Cash-based trading, is a well-known but relatively quiet character in China’s crypto circle. Typically, Yang doesn’t talk that much about his journey launching the mining pool, nor about CoinEx, which launched in December 2017.
And he almost never speaks about his fervent support for BCH, a hard fork of Bitcoin, and his now even more enthusiastic belief in BSV.
Yet that’s changing of late. Yang has been more active in recent months, participating in interviews about CoinEx and tweeting more frequently on Weibo, China’s Twitter. He’s been making controversial statements predicting the death of BTC, while supporting BCH and BSV on social media.
Recently, Yang told me that as a developer rather than a business person, he’s never been comfortable speaking in public. However he’s making an effort now to help publicize his renovation of CoinEx. So, for this week’s da bing, I decided to chat with him and get a peek into the mind of a veteran crypto entrepreneur who’s trying to make a personal, as well as a platform, comeback.

CoinEx’s golden opportunity

The first hard fork of Bitcoin occurred in August, 2017 and created a new cryptocurrency called Bitcoin Cash. The fork was prompted by partisans, including Yang, who wanted bigger block sizes on the blockchain — the basic idea was that bigger blocks would enable more transactions per second and make Bitcoin Cash something people would actually use to buy things, rather than Bitcoin’s more commonly perceived use as a store of value.
Yang added a tremendous amount of value to the mining scene in China. As a technical founder with has years of experience in big tech firms such as Tencent, Yang is proud of his #buidl skills. He developed most of the code in the early days of VicBTC, which became one of the biggest mining pools to this day.
Not satisfied with owning just a mining pool,Yang conceived of CoinEx, which was born in December of that year, specifically to carry on the mission of the newly forked Bitcoin Cash blockchain. As he got swept up in Bitcoin Cash enthusiasm, he even said that “BCH is bitcoin.”
CoinEx’s strategy was BCH-focused from day one; BCH was its base currency, meaning you could use it to buy and sell other currencies, such as Ethereum and Litecoin.
Interestingly, Jihan Wu, the co-founder of Bitcoin Exchange — himself a famous BCH supporter — was a big investor in the exchange. That made me wonder why he, Yang, and many other OG crypto miners, were so passionate about BCH. Was it just about bigger block sizes?
“Bigger block size means more users and use cases,” Yang explained. The move to bigger block sizes was attractive to miners because they would facilitate more transactions. Miners make money on transaction fees, as well as mining blocks. Likewise, the network would arguably be more useful to people, who were looking for digital cash for every day use.
That especially resonated with many early hardcore Bitcoiners. Said Yang: “We really believe that Bitcoin should be a P2P cash vehicle rather than a store of value.”
This view probably sounds outdated to people who believe that Bitcoin’s value as cash is long gone, with solutions such as Lightning Network fulfilling that role. Instead, the new narrative for Bitcoin resides in its value, rather than utility. Yet Yang believed that the forked network would create far more opportunity
“We could invite influential companies to establish nodes and contribute to the network. This cannot be done with the original Bitcoin architecture,” he said.

CoinEx pivots

But from its inception, CoinEx struggled with adoption and was dwarfed by the bigger exchanges. Part of that had to do with the fact that BCH and “Bitcoin Satoshi’s Vision,” another Bitcoin hard fork, were both controversial. Critics pointed out that these networks are centralized in a few big mining pools, and 51% attacks are not out of the question.
So over time, though Yang’s exchange still maintains strong support for BCH and BSV, it began to add support for all the major currencies.
Finally, in January of this year, it announced a major upgrade, of… well, just about everything. It started to offer futures trading, leveraged trading, options trading, and over 100 token projects available to traders. It even rolled out its own blockchain, “CoinEx Chain” to support a new DEX, “CoinEx DEX.”
https://preview.redd.it/3okoy5mudv051.png?width=1432&format=png&auto=webp&s=7099249da4a95db873d268f2dfc95d8db93a368e
The seemingly sudden publicity of CoinEx should not come as a surprise, then. As BCH/BSV was being marginalized, Yang shifted his focus. He’s now trying to ride the wave of building a bigger, more dynamic exchange.
“Crypto exchanges are where value is discovered,” Yang told me.

CoinEx: TNG

Building an exchange isn’t done overnight, nor is re-building one. CoinEx is still competing with the giants such as Binance.
However Yang thinks his exchange will thrive by zigging when his competitors zag. As usual, CoinEx is taking a slightly different route, he told me.
Like what? “We will be listing 小币种,” he said, using the expression for “small token projects.” I cannot help but wonder if these “small token projects” are simply shitcoins, the trading of which is certainly not new.
Indeed, Yang said that he’s banking on the success of his new, public blockchain. “We are building a CoinEx Chain, a layer one protocol for DEX alone. Using our public blockchain, anyone can issue any token, at any time,” he said. He described the blockchain as “a real decentralized, token-issuance and transaction platform.”
This is the core of Yang’s plan and vision. He believes that centralized exchanges will be a bottleneck for crypto adoption because it contradicts crypto’s nature as a completely free and open infrastructure. Essentially anyone should be able to launch a token and trade it with anyone. Only by building DEXes can we achieve full decentralization, he says.

The Religious nature of Bitcoin, and forked Bitcoin

It’s his belief that Bitcoin should adhere to Satoshi’s original vision that led Yang to send yet another controversial tweet last week, which I will translate: “The early days of Bitcoin expansion are similar to religion. The religious fervor brings prosperity to the industry.”
By extension, Yang believes that the next generation of Bitcoin should provoke a similar “religious” fervor. That’s why he has slowly become more of a BSV advocate than a fan of Bitcoin Cash. Yang believes that “BSV has more religious connotations, despite its negative image.” (As most crypto people know, the controversial Craig Wright, who claims to be Satoshi Nakamoto, led the hard fork which created BSV. Consequently it is often met with skepticism and derision.)
“The early days of Bitcoin expansion are similar to religion,” said Yang. “The religious fervor brings prosperity to the industry.”
Crypto is famous for its tribalism. Many people choose one camp over another not for practical reasons but because of simple faith. Talking to Yang and reading his tweet brings a historic texture to the Bitcoin narrative. But crypto cannot survive on religion alone. One has to build. Hash might have been worshipped in the old days but now the crypto religion is all about the size of the congregation.

MiniSwap -- A New Hybrid Incentive Model in DeFi

Cryptocurrency exchanges process over $20 billion in trade volume per day. Most of the transactions are going through centralized exchanges, where the users need to fully trust them for managing their assests and transactions. However, the risk of trusting these centralized exchanges has also been seen. For example, QuadrigaCX, which was the largest cryptocurrency exchange in Canada, lost $19 million of their customers' assets [1].
Decentralized Exchanges (DEXes) have been introduced to address this problem -- they allow traders to purchase and sell cryptocurrencies in a peer-to-peer manner, so no involvement of any trusted party is required. Atomic Swap is one of the promising technology for implementing a DEX. While it enables pure peer to peer trading, it also introduces problems such as unfairness and long confirmation latency. While existing work [2] has provided a solution towards a fair atomic swap protocol, the issue of long confirmation latency is inherent.
Another promising direction is leveraging liquidity pools. With liquidity pools, pairs of assets are reserved for trading. For any pair of assets supported by the liquidity pool, traders can exchange their assets without any third party. As traders can only perform the transactions if there are reserved assets, one core problem is how to attract liquidity providers to provide liquidity by reserving assets. It is not difficult to see that incentive [3,4], which has been a key component of all permissionless blockchains, can be equipped to incentivize liqudity providers. However, flawed incentive designs will lead to attacks and other concerns [5-13].
There are two main types of incentive designs, namely "trans-fee mining" and "liquidity mining". They are different from the Proof-of-X mining in blockchains for reaching consensus (a detailed analysis can be found in the survey [14]). Rather, they are used to incentivise users to join the ecosystem.
"Trans-fee mining" was proposed by FCoin in 2018 [15]. With FCoin, each time a transaction is created, 100% of its transaction fee will be returned in FCoin token to the payer as a reward. This is one incentive design to encourage traders to join the system. However, as FCoin may have no value to the trader, FCoin also introduces extra reward to all coin holders -- 80% of the transaction fee in its native currency (such as ETH) will be distributed to all coin holders. So, traders are incentivized to join the system, becoming a holder of FCoin token, and obtaining a share of the transaction fee of every transaction in the FCoin ecosystem.
While this had successful attracted traders, it is not sustainable. Rather than charging a trader to perform transactions, FCoin rewards traders. Profit-driven traders will create transactions at full speed to earn FCoin token and the share as a token holder. Indeed, the trading volume of FCoin was the top one among all exchange services, and the daily reward can be as high as 6000 BTC [16]. However, once all coins are minted, then the system would lose liveness as there is not enough supply to be distributed.
"Liquidity mining" aims at giving reward to the liquidity providers rather than the traders. There are different ways to implement liquidity mining. Compound [17] is a famous example of protocols deploying liquidity mining. With Compound, users become a liquidity provider by supply assets to a pool and obtain interests for its contribution (similar to depositing money into a bank). Liquidity providers first reserve some assets in the pool and obtain "cToken" of Compound which entitles the owner to an increasing quantity of the underlying asset. Users can use their "cToken" to borrow different assets available on the Compound and pay some interests to Compund. The borrowers may have some quick gains through the financial games [18]. Both borrowers and liquidity providers can withdraw their asset by trading them back with "cToken". Oners of "cToken" can also manage the business direction and decisions of Compound through weighted voting. The potential concern here is that rich users might be able to take over the control of the system.
Uniswap [19] is another popular DEX deploying liquidity mining. Uniswap incentivizes liquidity providers by giving them a share of the earned transaction fees. In particular, Uniswap changes each transaction a 0.3% fee, where 0.25% will be distributed to the liquidity providers, and 0.05% will go to the Uniswap account. One issue is how to incentivize traders. With Uniswap, traders are incentivized by the potential profit it can gain through the price difference between Uniswap and other exchanges. Uniswap price oracle is based on a constant function market makers [20,21], where the product of the number of reserved tokens is a constant. For example, if Uniswap has a pair of X token A and Y token B, then when a user using X' token A to buy Y' token B, the product of the reserved number of tokens should remain the same, i.e., XY = (X+X')(Y-Y'). The price of Uniswap (V1) is also defined in this way. This allows traders to speculate in the exchange market as the asset price on Uniswap is changed dynamically and is different from other exchanges. This, on the other hand, may have a security risk as the price can be easily manipulated. Uniswap (V2) fixed this problem by taking an accumulated price over a period of time [22]. However, as speculation/manipulation becomes harder, the trading volume may decrease.
MiniSwap [23] introduces a hybrid model (a mixture of "trans-fee mining" and "liquidity mining") to address the above issues. MiniSwap provides three types of rewards. For each trade with transaction fee f ETH in MiniSwap, a number of MiniSwap tokens (called MINI) worth 2f ETH will be minted. A (parameterized) portion of the tokens are given to the trader, and the rest are distribued to the liqudity providers. The transaction fee (f ETH) is used to exchange MINI in the liquidity pool. 50% of the obtained MINI will be distributed to all MINI holders, and the other 50% will be destroyed. In this way, both traders and liquidity providers are incentivized to join the ecosystem.
Recall that with FCoin, there is a problem when all coins are minted. MiniSwap has an upper bound (of 500,000 tokens) on the number of tokens can be created every day, and this limit reduces every month until a point where the limit (18,000 tokens) remains unchanged. This guarantees the sustainability of the system as the mining process can last for 100 years. The parameterized ratio of tokens as the reward to the trader and liquidity provider can also strengthen sustainability. It enables the system to dynamically balance the incentive of different parties in the system to make it more sustainable.
Overall, the MiniSwap hybrid model has taken the benefit of both "trans-fee mining" model and "liquidity mining" model, while eliminated the potential concerns. Formally defining and analyzing these models, e.g. through the game-theoretic approach [24], would be an interesting direction.

I get a lot of questions about bitcoin from friends and family members. I wrote this up and to the best of my knowledge covers everything a NOOB should know about bitcoin. That being said I probably made some mistakes and welcome any feedback from the community I could get on cleaning up the verbiage. Thanks in advance!
Bitcoin For NOOBS Peer to peer digital currency that is scares. It is digitally secure through cryptography and decentralized through open protocol mining principals.
Peer to peer: USD: paper dollars can be exchanged peer to peer but any other form of USD exchange requires your banks permission to use your own money. In fact if you try to pull out too much paper USD your bank may question you.
BTC: Can be exchanged with no middle man. No bank or government permissions needed for any amount and can be exchanged across the global at any time.
Scarsity USD: Print more money just write an IOU to the banks no big deal. Inflationary.
BTC: The number of BTCs that will ever exists is a fixed number it will never change. Deflationary.
Cryptography: USD: With USD the “keys” to your wallet lie with your identity. If I can gain access to your identity I can gain access to your funds. BTC: Your identity does not travel with the coin ledger. Stealing your identity does not mean your funds can be accessed.
Decentralization USD: The federal reserve banks are owned by unknown individuals. Make no mistake the illuminate exists. When the fed prints money the write those unknown individuals and IOU. Out of thin air wealth is created to individuals not the government. You don’t know who they are and never will. BTC: Anyone can mine bitcoin. You dedicate your hardware to mining aka processing transactions. It costs you money to run that hardware. Your reward for your hardware costs is bitcoin. The mathematical principals behind bitcoin do a check for how many mining machines decided if a transaction is real or not. 51% wins. The more bitcoin is used and the more people that dedicate hardware to mining the more digitally secure it becomes.
Bitcoins case for calling it gold 2.0: Currently bitcoin is not acting like the USD but instead acting more like gold a store of value. Long ago before the dollar gold was the standard. The government attempted to issue greenbacks however no one wanted them since gold was the tradition and was scares in supply. The government decided to back the dollar with federal gold reserves. Federal reserves no longer exist as they once have in fact if you invest in gold via the stock market there is a slim chance it is backed by any type of gold reserve it’s really just all digital money for the most part now a days. While bitcoin is truly limited in supply and scares not only is it a great store of value but it has even more use than gold. It can be exchanged electronically peer to peer across the globe and used via smart contracts etc. A quick google search say that the total value of gold in the world is at roughly 7.5trillon dollars. Gold does has more use than just a store of value via jewlery electronics etc but let’s compare the numbers side by side.
Gold 7.5 trillion BTC market cap 170.5 billion
If you agree BTC is a better store of value or at least a decent store of value since it’s truly limited in supply with more usability then it’s easy to see how much upside potential is left on the table. As the fed continues to put out more money during these economic hard times they are causing inflation while BTC has just undergone a halving aka it’s harder for miners to produce a bitcoin reward meaning deflation. Bitcoin is the perfect place for you to store that big fat government stimulus check if you don’t need the money for awhile.
Edit: added these sections based on feedback from friends.
Dollars and cents: USD: One dollar can be broken down into .01 dollars or 1 cent. This is the smallest unit of measure in USD. BTC: 1 Bitcoin can be broken down into .00000001 bitcoins or 1 sats which is short for Satoshi’s. 1 sat is the smallest unit of measure in terms of BTC.
Owning Bitcoin: You can own bitcoin a few different ways but we will talk about two methods in general. Owning coins through a 3rd party such as Coinbase or Robinhood vs owning your coins via your own hardware wallet. 3rd Party: The platform you use can hold some control over you and limit your funds etc just like a bank. They will take additional fees for each transaction you place etc. This really isn’t what bitcoin was intended for but it’s how most people use it currently. Hardware wallet: You own the currency on a hardware wallet like a Ledger wallet etc. there is no middle man. You own the coin and the “keys”

If every US citizen that receives a stimulus check wanted to buy 0.1 BTC... it wouldn't be possible. There isn't enough

And that is being overly generous. There could likely only be less than 0.04 btc per person to go around... if no one else in the world buys any before them. Someone check my math if I'm off, but thought this would be interesting to theorize.
I am not saying that this would happen (as it definitely wouldn't.) Just wondering what is even possible if the demand increased that much.
So here we go: Of the $2.2 trillion stimulus package, approx $300 billion is going out as $1,200 stimulus checks. Which would be divided up for 250 million citizens.
Current supply of bitcoin is around 18 million coins mined. However it is estimated that 3-4 million are lost forever. So let's say that our actual supply available to trade is 15 million (conservative guess).
If the current total supply mined is 18 million, approx 11 million coins (60% of the total supply) haven't moved from their wallet in 2 years. If we subtract the estimated 3 million lost... That leaves 8 million unlost coins have been held for at least 2 years.
For arguments sake, let's say that 3 million of those holds will sell if the price increased and the other 5 million will continue to hold. That would leave 3 million that would go from hold to circulation plus the 7 million that are newly minted or already circulating.
= my estimate of 10 million coins available for market demand
Divide the 10 million coins by the 250,000,000 citizens with a stimulus check and you get 0.04 BTC per person...
Now could someone figure out a theoretical price point if demand reached that high? My guess would be to get an average rate of increase vs supply and volume during the 2017 bull run to see the rate of price increase as supply diminishes.
Again, this is no prediction. Just wanted a better picture in my head of how rare having 1 full BTC is going to be.

PoW or PoS: The Difference Between Mined and Non-Mined Crypto

PoW or PoS: The Difference Between Mined and Non-Mined Crypto
The whole crypto world discusses how Ethereum will switch from Proof of Work to Proof of Stake now. This change can significantly affect the cryptocurrency market. What are the positive and negative sides of PoW and PoS?
Cryptocurrencies can be divided into two types: those that can be mined (Bitcoin, Litecoin, Monero) and pre-mined ones (Ripple, Stellar, Cardano, EOS, NEO).

What is the big difference?

Although they differ in the method of generation, the basis of both types of crypto is the same: verification. Every transaction processed by the network must be verified by someone to ensure that virtual money has not been spent twice. Here we are talking about the difference in the verification process. Transaction groups are combined into a block; after verification, the block joins other previously confirmed blocks, and create a chain of transactions, or blockchain.

PoW: Mined Crypto

Mining is a process in which individuals, groups, or companies solve complex mathematical equations to verify transaction blocks using powerful computers. These math problems are part of the encryption process that protects transactions from cybercriminals and third party access.
The first who solves the problem and signs a block of transactions receives a reward. The miner, who confirmed the block of transactions e.g. in the Bitcoin network, receives a reward in BTC.

Disadvantages of Mined Crypto

  • Mining can be very expensive due to the large amounts of electricity consumed. In mined crypto with less capitalization, competition is usually lower than in BTC.
  • BTC mining requires special ASIC chips, that are combined into huge farms. Electricity is one of the main expenses for these projects. That is why China, where electricity is relatively cheap, has become a home to four of the five largest Bitcoin mining companies in the world.
  • Mining farms have to spend significant money funds on new equipment, which becomes out of date very fast.
  • Large projects need additional cooling, as servers and graphics cards heat up to high temperatures during operations.
  • The Proof-of-Work model is potentially vulnerable to a 51% attack (when a group of people with 51% of the computing power gains control of the network and its participants). For popular cryptocurrencies such as Bitcoin (BTC), Litecoin (LTC), and Monero (XMR) this is not a problem due to their large capitalization. However, minor cryptocurrencies with long block processing times and low daily volumes are risking a lot.

PoS: Non-Mined Crypto

At the other end of the spectrum are pre-mined cryptocurrencies such as Ripple (XRP), Stellar, Cardano, EOS, and NEO.
In the PoS model, super-powered computers are not needed, and participants do not compete for the right to sign the next block. Thus, the costs of this approach are significantly lower. Transaction verification is carried out by cryptocurrency owners. The more cryptocurrencies you have, the longer you own it, the higher the probability that you will be selected to check the transaction block.
Certain mechanisms are built into the system that prevents the dominance of large cryptocurrency holders over the verification process. There are many random ways to select owners who get the right to sign a transaction block. This ensures that small holders have a chance to participate in the process.

Disadvantages of Non-Mined Crypto

Despite the fact that the costs of the Proof-of-Stake method are lower, PoS has its drawbacks.
  • Such cryptocurrencies are not threatened by an attack of 51%, however, another trouble replaces it — a person who posses 51% of all tokens in circulation can gain control of the network and its participants. Of course, in the case of cryptocurrencies with high capitalization, the possibility of this scenario is low, but small partners may suffer from this vulnerability.
  • The Proof-of-Stake model also gives major owners additional votes in determining the future development of the network. Most NEO tokens) belong to several founders, for instance. This helps increase transaction speed and reduces consensus-building time, but also makes cryptocurrency too centralized. In other words, in the PoS model, large players gain significant power, which is theoretically impossible with the PoW model.

Which method is better?

Both methods have their pros and cons. Nevertheless, sooner or later, some of the largest mined currencies (e.g. BTC) will reach their token limit. At this point, they will have to switch to Proof-of-Stake. Since it significantly reduces power consumption and doesn't require powerful computers, gradually all crypto including BTC will switch to a non-mined model just like Ether did.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.

Bitcoin (BTC)A Peer-to-Peer Electronic Cash System.
  • 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 a blockchain network structure, a notion first created by Stuart 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.

1. What is Bitcoin (BTC)?

  • 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).

2. Bitcoin’s core features

For a more beginner’s introduction to Bitcoin, please visit Binance Academy’s guide to Bitcoin.

Unspent Transaction Output (UTXO) model

A UTXO transaction works like cash payment between two parties: Alice gives money to Bob and receives change (i.e., unspent amount). In comparison, blockchains like Ethereum rely on the account model.
https://preview.redd.it/t1j6anf8f3151.png?width=1601&format=png&auto=webp&s=33bd141d8f2136a6f32739c8cdc7aae2e04cbc47

Nakamoto consensus

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 blockchain

Block production

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:
  1. Alice sends Bob 1 BTC, and Bob sends Merchant Carol this 1 BTC for some goods.
  2. 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.
  3. 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.
  4. Now Carol will not receive his 1 BTC, as the network looks for transaction 12345 to ensure that Bob’s wallet balance is valid.
  5. 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

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.

I support Bitcoin ABC and the IFP

I, maff1989, in support of the miners' intent to fund their software infrastructure to grow Bitcoin Cash to be the most competitive peer-to-peer electronic cash for the world, pledge to pay a minimum of $0.10 in fees for each economic (i.e. value-exchange) transaction I make using the Bitcoin Cash network during the period of May 15th 2020 to November 15th 2020.
Assuming a current BCH price of ~$338, we take the 5% block reward reduction from the IFP and a 6.25 BCH base block reward (May 15 IFP = post-halvening). To offset the 5% block reward reduction completely, it would only take ~1060 transactions per block, each paying a $0.10 transaction fee.
6.25 BCH * 5% = 0.3125 BCH (reduction per block reward)
0.3125 * $338/BCH = $105.63 (paid to dev address)
~$106 / $0.10/tx = 1,060 tx/block
Over time, as the price of BCH rises in contrast to BTC (and with the right marketing and timing, it will), and/or the amount of economic activity increases on the BCH network, the number of transactions required by each user to pay the $0.10 fees will reduce, since the decreased BCH/BTC ratio and/or increased activity will offset the 5% block reward reduction even further - or completely - as miners switch to mining BCH due to increased consistent profitability vs BTC. :)
And even if the BCH price goes down in the interim, then paying a minimum $0.10 per transaction will only further incentivize hashrate to mine BCH vs BTC.
After all, BCH needs hashrate for security.
The halvening is upon us. The confidence is gone. Ask yourselves this: would you be confident in the value of a chain where the miners and developers weren't working together in an attempt to bolster functionality and infrastructure; to proceed more hastily down an already-established roadmap; especially at the current time in history?
Wouldn't you feel more inclined to support a movement like that with your transaction fees?
I mean, let's think about it for a second: motherfuckers paid $0.50 per transaction to feed chickens across the Internet. Motherfuckers like me did it, too. It was fun!
Why can't the IFP be fun, too? It's an attempt to mature the ecosystem; to truly test Nakamoto Consensus between each equal component within: devs, miners, and especially users. I wanna take part in that test of time, and I'm putting my money where my mouth is. I hope more people feel the same.
