What is Hard Fork

A hard fork is a substantial change to the protocol of a blockchain that is not backward-compatible. Hard forks are the creation of blockchain systems that diverge from the original chains. Nodes must "decide" whether to join the new protocol or not. This procedure generates two incompatible parallel chains, each with a duplicate record of the previous chain, including data about all users' assets. Hard forks often trigger one of two responses from miners. In one scenario, nodes upgrade their software willingly to adhere to the new protocol of a scheduled hard fork. Occasionally, though, community disagreement occurs, resulting in a blockchain split. Nodes that agree with the changes join the new forked-off chain, resulting in the creation of a new version of the currency, whereas nodes that disagree do disagree remain on the original chain. Bitcoin hard forks have created alternative Bitcoin currencies such as Bitcoin Private and Bitcoin Cash. The price of a blockchain’s native currency may become volatile during a hard fork.
