For users of Bitcoin currently, certainly the term Hardfork Bitcoin is already no stranger to be heard. What the heck is actually Hardfork Bitcoin it? Simply put, Hardfork is defined as extreme enough change to be made on core bitcoin. In General, Hardfork is done when nodes in a network of Bitcoin be could not validate a new valid block because there is a difference between a node that has yet to update its core hardware node with the Bitcoin has sported a consensus the new Protocol.
This condition occurs when there is a difference of views between the Bitcoin Unlimited with Bitcoin Core. Bitcoin nodes Core still recognizes a new valid block size less than 1 mb, while the Bitcoin nodes Unlimited recognizes valid block size is more than 1 mb. Usually the condition difference of views about the new block consensus are deemed valid if there are repeated then it makes no difference as Malicious Attacker against consensus bitcoin. This means when on one chain (blockchain network) there are two different consensus, then the difference in this view will become permanent.
This would culminate implies a new block in the validation process. While the block-block the bitcoin new inside there are hundreds to thousands of transactions that must be validated in advance by the miners. The only way that must be taken at the time could not produce consensus was more decision-making is through the Hardfork. On the other hand, Bitcoin Core also tried to maintain the main character of the bitcoin decentralization. While the Bitcoin Unlimited did try to meet their needs so that the limit of the bitcoin can block gets larger.
Maybe after that, you will ask, then what will happen next? Most likely when Hardfork Bitcoin happen is there will be a split network of bitcoin. On each of the Bitcoin Unlimited and Bitcoin Core will eventually run on two different networks. If this happens, then the next stage is Bitcoin Unlimited does not change as new Altcoin. While the Bitcoin Core will remain as usual.
Split or separation done between Bitcoin Core with this Unlimited Bitcoin each will run on different blockchain. Bitcoin Core position, will remain on the block the longest. chains forming While the Bitcoin Unlimited will be bada new chains with different Bitcoin Core.
It could be inferred that the possibility of the occurrence of Hardfork is a sequence of the bitcoin scalability perbedatan which heat up on some time ago. On the limit of the bitcoin block debate there is indeed some great proposals to increase the size limit of a block, i.e. Bitcoin Unlimited and SegWit. Both have the same difference resulted in the possibility to do Hardfork.
The actual implementation of SegWit is not yet secure enough when it must be reached by the road Hardfork. Vice versa with Bitcoin Unlimited. But there is a difference between the two options. When feature SegWit is enabled, then it will be considered as a door opener from some other innovations that allow do bitcoin. Arguably such innovations as the application of Lightning Network, or also with Sidechain can expand the capabilities of the bitcoin.
Hardfork event will occur when a developer team cryptocurrency agreeing to implement new features or changes to system programming of coin. Typically this would be done to secure the cryptocurrency network as well as the number of users of adapting to an increasingly large coin. Hardfork can cause incompatibility between the old version with the new version, so that all users of the cryptocurrency indeed should be willing to update all applications associated with this coin in order to keep trade with either.
