Bitcoin cash split candy
The capacity of a block in bitcoin is 1m (megabytes). A transaction is between 250 and 500 bytes
according to this algorithm, a block contains about 4194.3 transactions
the confirmation time of a block in bitcoin is 10 minutes, so the seven transactions that a block can process per second may sometimes be less than seven
What are the consequences The bifurcations of 
bitcoin are divided into hard bifurcations and soft bifurcations
hard fork means that when the block format or transaction format of bitcoin changes, the UN upgraded nodes refuse to verify the blocks proced by the upgraded nodes
the upgraded nodes can verify the blocks proced by the non upgraded nodes, and they continue the chain they think is correct, so they are divided into two chains
What is soft bifurcationsoft bifurcation means that when the data structure of bitcoin transaction changes,
UN upgraded nodes can verify the blocks proced by upgraded nodes,
and upgraded nodes can also verify the blocks proced by UN upgraded nodes
BCC does not meet the definition of bitcoin network bifurcation. BTC and BCC are two completely different chains in two days. As like as two peas, the whole network as like as two peas, which can not be synchronized in one chain, has two pieces of block chain network with identical bitcoins. Two networks have a large number of miners digging, and transactions on two different networks can not be synchronized. This leads to two even the same difficulty of two parallel chains, which is called forking.
BCC has also been identified by bitcoin international Roundtable forum as a competitive currency that replicates bitcoin blockchain and modifies some codes. Therefore, it is a wrong interpretation that BCC is the network fork of bitcoin.
bitcoin cash is affected by the tightening of domestic policies, and its price will continue to be low, especially the two sessions and G20 summit in March, which will have a huge impact on bitcoin cash. If the policies are good, bitcoin cash will return to the high point, if the policies are bad, it will continue to shake the market.
The concept of bitcoin was first proposed by Nakamoto on November 1, 2008, and was officially born on January 3, 2009. According to the idea of Nakamoto, the open source software is designed and released, and the P2P network on it is constructed. Bitcoin is a virtual encrypted digital currency in the form of P2P. Point to point transmission means a decentralized payment system
bitcoin (BTC) is the most popular digital currency in the world. The spread occurred on August 1, 2017. In a "hard fork" event, a new digital currency called bitcoin cash (BCH) was born
e to version switching, bitcoin blockchain is bifurcated into two independent blockchains. Everyone who owns bitcoin before the fork is entitled to the same amount of "bitcoin cash" tokens, similar to a dividend in a stock
bitcoin cash (BCH) is a new version of bitcoin with different configurations launched by a small number of bitcoin developers. It is a new type of blockchain asset. On August 1, 2017, the mining of bitcoin cash will begin, and each bitcoin investor will have the same amount of bitcoin cash (BCH) in his account

currency features
Decentralization: bitcoin is the first distributed virtual currency, and the whole network is composed of users without a central bank. Decentralization is the guarantee of bitcoin's security and freedom
Global Circulation: bitcoin can be managed on any computer connected to the Internet. No matter where you are, anyone can dig, buy, sell or collect bitcoin
exclusive ownership: private key is required to manipulate bitcoin, which can be stored in any storage medium in isolation. No one can get it except the user himself
low transaction cost: bitcoin can be remitted free of charge, but a transaction fee of about 1 bitfen will be charged for each transaction to ensure faster transaction execution
no hidden cost: as a means of payment from a to B, bitcoin has no cumbersome quota and proceres. If you know the other party's bitcoin address, you can pay
cross platform Mining: users can explore the computing power of different hardware on many platforms

1. They hype themselves and pave the way for their bifurcating bitcoin. For example, Liao Xiang, who once strongly opposed big blocks, paid big money, and they all bifurcated bitcoin
2. Misled by the core development team, the melon eaters regard the miners as a group of criminals
3. The core development group's opposition to BCH is not only a divergence of development roadmap, but also a dispute of interests. The lightning network promoted by the core development group can make the gold owners behind it profit through the lightning network.
of course, bitcoin cash has been forked once. The forked currency can be traded on microbit, and the price has plummeted a lot, which is basically negligible. This is also the case with most of the forked currencies
bitcoin cash has removed isolation verification, and currently supports 8m, which has great advantages in stability and handling charges.
section one: why do you split up when you don't say a word
the concept of bifurcation originated from bitcoin
as we know, bitcoin trading is based on bitcoin blockchain network (one block by one forms a chain of front and back Association, forming a bitcoin blockchain network). Since a block is a block, it must have capacity (let's fill in the block, it is nothing more than a collection of codes), The size of the block capacity will limit the efficiency of the transaction. If the block capacity is too small, the smaller the number of transactions will be. Once the transaction volume is too large, it will cause congestion
the capacity of bitcoin block is only 1m, and it can hold only 5-7 transactions. In the past, there were relatively few users for bitcoin transactions, so this capacity is no problem. However, with the rise of bitcoin price, more and more users swarmed in, and the bitcoin block could not accommodate so many transactions, resulting in congestion
bitcoin is anxious: slow down, brother Dei, I can't keep up with your trading speed. Hello! Users are also anxious: brother, can you hurry up
this is a big problem, not only because we have limited patience, but also because bitcoin's positioning is currency. As a currency, you should pay and collect money quickly, accurately and ruthlessly. If you are always so slow, when can you realize the currency attribute? So, this is a big problem
of course, the bitcoin community knows the importance of this problem. As for how to solve this problem, the bitcoin community is divided on whether to expand the capacity of bitcoin blocks (as we have just said, it is too little capacity of bitcoin blocks that leads to slow transaction speed and congestion)
the controversy is mainly divided into two camps:
the original development team of bitcoin, led by core, believes that bitcoin is an electronic gold of value storage, which will destroy its core once it is expanded
however, the mining team led by Wu Jihan believes that bitcoin should be a kind of currency with rapid circulation in the future, and it needs to be expanded to solve the problem of transaction congestion. Because of the decentralized nature of the blockchain, no indivial or organization can decide how to "expand" the bitcoin system. Everyone has their own opinions, and their opinions are divided. No one is willing to give in. Therefore, everyone goes their own way. The bitcoin chain has split into BTC and BCH chains, and over time it has evolved into the so-called "bifurcation"
this is the origin of bifurcation
what happens after the second section bifurcates
for blockchain, bifurcation is the change of blockchain protocol, which is similar to upgrading the blockchain to make up for the shortcomings of the system. This is just like our current mobile phone software often prompts you to upgrade
however, we know that blockchain is decentralized. Unlike your mobile software, developers can upgrade when they say so. In the world of blockchain, any modification needs the consensus of all members. No one can decide when to change or how to change the underlying agreement of blockchain
therefore, when the original development team of bitcoin and the miner team have differences, the system will be divided into two parts, and two new systems based on the original blockchain will appear. Everyone has their own problems, and no one can intervene. In this way, the bitcoin system is divided into two chains: BTC and BCH, which are called "bifurcations", and BCH is called bifurcated currency (the bifurcated currency of bitcoin)
in fact, not only BCH, but also bitcoin has many bifurcated coins. Why is BCH the first thing to think of when it comes to bifurcated currencies? This is because BCH is a successful bifurcated currency. When its market value is the highest, it ranks the fourth in the list of cryptocurrencies, next only to bitcoin, Ethereum and EOS
section 3 hard fork and soft fork
let's make a metaphor: if bitcoin system is the trunk of a big tree, then BCH and other fork coins are the branches of the tree. However, bifurcation is not as simple as this metaphor. It can be divided into hard bifurcation and soft bifurcation
first, hard bifurcation: goodbye, never see again
the BCH we mentioned above belongs to hard bifurcation. Hard bifurcation means that nodes using old software can no longer verify blocks proced with new software nodes. If you want to verify, you can only upgrade. After upgrading, it is equivalent to changing the track and running on another new system. Just like BCH to BTC, BCH is a brand new track (a brand new chain), and the coin on this chain is BCH (bitcoin cash). Then, nodes using BCH system can no longer go to BTC network for transaction verification. Hard bifurcations, generally speaking, mean going their own way. There is no intersection any more< Second, soft bifurcation: getting better to meet again
soft bifurcation is opposite to hard bifurcation. Soft bifurcation means that nodes using the old version can verify the blocks proced by nodes using the new version, and nodes using the new version can also verify the blocks proced by nodes using the old version. The two versions are compatible
the way bitcoin upgraded its isolation witness in 2017 is soft bifurcation. In the whole process, it doesn't matter whether we use the old version or the new version, because they are compatible. The new version only solves some problems better. In essence, we are still running on the bitcoin chain, and there is no new coin
to sum up, the difference between soft fork and hard fork is whether nodes using old software can be compatible with nodes using new software. Compatibility is soft fork, while incompatibility is hard fork.
bitcoin cash is the proct of the three-year battle for bitcoin expansion. The main supporters and promoters of bitcoin cash are supporters and developers of large blocks
bitcoin cash is not a kind of bifurcated currency, and bitcoin cash does not meet the definition of bifurcated currency. Bitcoin cash and bitcoin are two different blockchains.
