Bitcoin users at this time, of course the term Hardfork Bitcoin is no stranger heard. What exactly is Bitcoin's Hardfork? Simply put, Hardfork is defined as a fairly extreme change that must be done on bitcoin cores. whereas in general, Hardfork is done when the node in the Bitcoin network becomes unable to validate a valid new block because there is a difference between nodes that have not updated the Bitcoin core device with nodes that have adopted a new protocol consensus.
this situation occurs when there is a different view between Bitcoin Unlimited with Bitcoin Core. The Bitcoin Core node still recognizes a valid new block size of less than 1 mb, while the Bitcoin Unlimited node recognizes valid blocks of more than 1 mb. Usually the condition of different views about the new block consensus that is considered valid if it occurs repeatedly then it does not make any difference as Malicious Attacker to the bitcoin consensus. This means that if in one chain (blockchain network) there are two different consensus, then the different views will become permanent.
this will culminate in the valid validation of new block validation process. While the new blocks of bitcoin in it there are hundreds to thousands of transactions that must be validated first by the miners. The only way to go when it can not produce a consensus decision-making is through the Hardfork road. On the other hand, Bitcoin Core also tries to retain the main character of the decentralized bitcoin. While Bitcoin Unlimited is trying to meet its needs so that block bitcoin limit can grow larger.
after that, maybe you will ask, then what will happen next? Most likely if Hardfork Bitcoin happens there will be a bitboxin network split. Each Bitcoin Unlimited and Bitcoin Core will eventually run on two different networks. If this happens, then the next stage is Bitcoin Unlimited unchanged as the new Altcoin. while Bitcoin Core will remain as usual.
the separation between Bitcoin Core and Bitcoin Unlimited will each run on different blockchains. Position, Bitcoin Core will remain at the longest chain block consensus. While Bitcoin Unlimited will be a new bada chain different from Bitcoin Core.
of course the Hardfork event will occur when the developer team of a cryptocurrency agrees to apply the new features and changes to the programming system of the coin. Usually this will be done to secure the cryptocurrency network as well as adapt to the growing number of coin users. Hardfork can cause a mismatch between the old version and the new version, so all the cryptocurrency users should be willing to update all applications associated with this coin in order to keep trading properly.
