What is the Term for a Blockchain Upgrade that is Backward-compatible and Does Not Result in a Split of the Blockchain? In blockchain technology, a soft fork is a change to the software protocol where only previously valid transaction blocks are made invalid. Because old nodes will recognize the new blocks as valid, a soft fork is backwards-compatible.

This kind of fork requires only a majority of the miners upgrading to enforce the new rules, as opposed to a hard fork that requires all nodes to upgrade and agree on the new version.

New transaction types can often be added as soft forks, requiring only that the participants (e.g. sender and receiver) and miners understand the new transaction type.

This is done by having the new transaction appear to older clients as a “pay-to-anybody” transaction (of a special form) and getting the miners to agree to reject blocks including these transactions unless the transaction validates under the new rules. This is how pay-to-script hash (P2SH) was added to bitcoin.
