In the discussion of blockchain, bitcoin and other digital currencies, we often hear the word "bifurcation". So what is bifurcation? What is the effect of bifurcation
blockchain
before talking about bifurcation, popularize a little knowledge of blockchain, so as to help us understand what bifurcation is more easily (if you don't have any concept of blockchain, please read my previous articles, which are all popular words to help you understand what blockchain is)
blockchain, as the name suggests, is a chain composed of blocks. Of course, this kind of chain is just a figurative metaphor. To put it bluntly, data blocks are connected orderly. In bitcoin, the transaction records of bitcoin are stored in the block. The size of the block and the space occupied by the transaction records determine how many transactions can be stored in a block. These transaction records are packaged into blocks, and then the blocks are connected one by one to form a blockchain
We know that bitcoin software, like other software, needs to be updated and modified regularly in order to make it better. So a new version will appear, but not everyone will download the new version, so one miner will run the old version, and some will run the new version. If the old and new versions are not compatible, the blockchain will bifurcate. Because there may be differences between the version blocks and the old version blocks, they cannot be connected to the same blockchain, so there will be two or even more chains, which is called bifurcation
soft forking
soft forking refers to that when the new consensus rules are released, nodes that have not been upgraded will proce illegal blocks because they do not know the new consensus rules, resulting in temporary forking. This kind of bifurcation will be graally repaired with the upgrading of nodes
hard fork
hard fork refers to the permanent divergence of the blockchain. After the release of the new consensus rules, some nodes that have not been upgraded cannot verify the blocks proced by the upgraded nodes, and usually hard fork occurs. Therefore, in the field of digital currency, hard bifurcation often leads to the emergence of new currencies. For example, the hard bifurcation of Ethereum led to the emergence of eth
What is bifurcation? What is bitcoin bifurcationunlike most currencies, bitcoin does not rely on specific currency institutions. It is generated by a large number of calculations based on specific algorithms. Bitcoin economy uses a distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses cryptography design to ensure the security of all aspects of currency circulation. The decentralized nature and algorithm of P2P can ensure that it is impossible to artificially manipulate the value of bitcoin through mass proction. The design based on cryptography can make bitcoin only be transferred or paid by the real owner. This also ensures the anonymity of money ownership and circulation transactions. The biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to 21 million.
bitcoin is actually an e-coin data coin proced by P2P batch software, which belongs to a network virtual asset so bitcoin is also called bitcoin. It is generated by a set of cipher codes through complex algorithms. This rule is not interfered by any person or organization. Anyone can download, run or participate in the manufacture of bitcoin. One of the biggest characteristics of bitcoin is that it cannot be forged< you can make money in the bitcoin market by investing time and money 
when you spend time on websites, you can visit these websites every few minutes to get a small amount of bitcoin. Therefore, we can do this if we have time. If you want to earn more, you should invest money in the early stage. Bitcoin also has a special casino, so you can earn more by luck
