Blockchain fork refers to the splitting of a blockchain into two or more branches due to inconsistent consensus rules. A hard fork is an incompatible upgrade that leads to a permanent divergence of the chain. In contrast, a soft fork is a compatible upgrade, and the chain can be merged back together.
