A fork in software refers to a change in the protocol or code of a blockchain. This change can lead to a split, resulting in two separate versions of the blockchain.There are two main types of forks: soft forks and hard forks. A soft fork is a backward-compatible change, meaning the updated and non-updated versions can still interact. This type typically involves minor adjustments to rules or features.A hard fork, on the other hand, introduces changes that are not backward-compatible. When a hard fork occurs, the blockchain splits into two distinct versions, each with its own history. This can happen for various reasons, including disagreements among developers or community members about the future direction of the project.Forks can result in new cryptocurrencies or enhance a project’s features. They often reflect differing philosophies and visions within a community, leading to innovation or division. Examples include Bitcoin Cash, born from a Bitcoin hard fork, showcasing how forks can create substantial changes in the landscape of digital assets.
