What is a fork in crypto? A#Forkrefers to a significant change or divergence in the protocol of a blockchain network. It is a term used to describe the splitting of a#blockchaininto two separate paths, each following its own set of rules. There are two main types of forks: hard forks and soft forks.#HardFork: A hard fork involves a significant change to the protocol that is not#backwardcompatible. It creates a permanent#divergencein the blockchain, resulting in two separate chains.#Nodesor participants that have not upgraded to the new protocol will continue to use the old chain, while those that accept the changes will use the new chain. Hard forks often result in the creation of new#cryptocurrencieswith their own separate blockchains.#SoftFork: A soft fork, on the other hand, is a backwards-compatible upgrade to the #protocol. It introduces changes that are compatible with the#existingrules, allowing nodes that have not yet#upgradedto continue validating transactions on the updated blockchain. In a soft fork, the blockchain remains a unified #chain, but the upgraded nodes will enforce additional rules.
