Fork
When developers make changes to a blockchain, such as adding new blockchain functionality, correcting security issues, creating entirely new coins, or even changing the consensus protocol that governs how blocks are created and validated on a blockchain
Example
“In 2017, Bitcoin underwent a hard fork that created Bitcoin Cash (BCH), giving every BTC holder an equal amount of the new coin as the blockchain split into two separate chains with different block size rules.”
