In blockchain, a fork is defined variously as: "what happens when a blockchain diverges into two potential paths forward" "a change in protocol", or; a situation that "occurs when two or more blocks have the same block height": glossary Forks are related to the fact that different parties need to use common rules to maintain the history of the blockchain. Blockchain technology solves these problems by creating a network of computers (called nodes) which each store a copy of the database, and a set of rules (called the consensus protocol) which define the order in which nodes may take turns adding new changes to the database.
