A contentious hard fork refers to a situation in a blockchain network where there is a significant disagreement among participants regarding proposed protocol changes or upgrades. It arises when a portion of the community supports and adopts a set of modifications to the blockchain's rules, while another faction opposes it. This disagreement leads to the creation of a new and separate blockchain diverging from the original one. Unlike a planned hard fork, a contentious hard fork often results in a permanent split, creating two distinct and incompatible blockchains. It can cause a divide in the community, resulting in competing chains and potentially different cryptocurrencies.
