Soft Fork

Action

A soft fork represents a protocol change in a blockchain network that remains backward-compatible, meaning nodes that have not upgraded can still process transactions and blocks, though they may not fully validate the new rules. This contrasts with a hard fork, which necessitates all nodes to upgrade to maintain consensus. Implementation typically involves a majority of the network adopting the new rules, effectively creating a new set of consensus rules without disrupting the existing chain’s functionality, and influencing derivative contract specifications. The success of a soft fork relies on economic incentives for node operators to upgrade, and its impact on market microstructure is often observed through changes in transaction fees and block propagation times.
