128. The fork is resolved when subsequent block(s) are added and one of the chains becomes longer than the alternative(s). Citation needed See also edit Alternatively, this situation is called a blockchain split 2 or a blockchain divergence. With neither side of the contentious debate leading up to the hard fork willing to come to a compromise, two competing implementations of the protocol have now been activated. Accidental fork happens when two or more miners find a block at nearly the same time. For example, Ethereum has hard-forked to "make whole" the investors in The DAO, which had been hacked by exploiting a vulnerability in its code. As of press time, m which is supporting Bitcoin ABC had mined a new block, signifying that the two chains have divided into two, according to data from. In case of a hard fork, all nodes meant to work in accordance with the new rules need to upgrade their software. To recap, the implementation put out by leading bitcoin cash developer group.
Simply put, a so-called hard fork is a change of the Bitcoin protocol that is not backwards-compatible;.e., older client versions would not accept blocks created by the updated client, considering them invalid. In 2014 the Nxt community was asked to consider a hard fork that would have led to a rollback of the blockchain records to mitigate the effects of a theft of 50 million NXT from a major cryptocurrency exchange. The last common block among bitcoin cash miners was #556,766, mined by SVPool. Ethereum and, ethereum Classic. In this case, the fork resulted in a split creating Ethereum and Ethereum Classic chains.
With several platforms closely tracking the outcome of events still to come, the future of the bitcoin cash community remains to be determined. Bitcoin ABC introduces a series of technical upgrades to the network, such as a reordering of transactions to increase block capacity as well as additional code to support greater interoperability between cryptocurrencies. Intentional forks that modify the rules of a blockchain can be classified as follows: Hard fork edit, a hard fork is a rule change such that the software validating according to the old rules will see the blocks produced according to the new rules. If permanent, it is also referred to as a cryptocurrency split. References edit Antonopoulos, Andreas (2017).

If one group of nodes continues to use the old software while the other nodes use the new software, a split can occur. USA: O' Reilly media, inc. Road image via Shutterstock. Notably, blockchain forks have been widely discussed in the context of the bitcoin scalability problem. Though refuted by Bitcoin ABC supporters as unlikely, data three days prior to hard fork activation revealed that bitcoin cash mining pools supporting Bitcoin SV actually consolidated a majority of the networks total hash power, suggesting strong capability to follow through on the threat. However, its unclear at this juncture which of the two will become the dominant software of the BCH network or if two distinct chains will continue to co-exist in the long-term. "Bitcoin Has Split Into Two Cryptocurrencies. Forks (in the sense of protocol changes) have been used in order to add new features to a blockchain, to reverse the effects of hacking or catastrophic bugs on a blockchain as was the case with the bitcoin fork on or the fork between.

On approximately November 18th, when block 494,784 is mined, a hard fork enabling the bitcoin network to carry 2MB blocks is expected to occur.
A blockchain split occurs during a hard fork which in turn branches the chain into two parts.
If this happens, there is nothing a bitcoin holder has to do but wait and watch the fork unfold.
