A blockchain fork is a divergence in the blockchain into two potential paths forward. It can occur in any crypto-technology platform- not only Bitcoin. There are two types of forks: soft fork and hard fork.

1. Soft Fork: A soft fork is a change to the software protocol where only previously valid blocks/transactions are made invalid. Since old nodes will recognize the new blocks as valid, a soft fork is backward-compatible. This kind of fork requires only a majority of the miners upgrading to enforce the new rules.

2. Hard Fork: A hard fork is a radical change to the protocol that makes previously invalid blocks/transactions valid (or vice-versa). This requires all nodes or users to upgrade to the latest version of the protocol software. Thus, a hard fork is not backward-compatible. When a hard fork is implemented, the old version nodes would consider the new transactions invalid. So to continue to mine valid blocks, all of the nodes in the network need to upgrade to the new rules.

Forks are a common phenomenon in computing software and represent a way for developers to update and alter a blockchain's protocol. However, they can also be a divisive issue within the blockchain community, as they often represent a divergence in vision and goals.
