The percentage of Bitcoin nodes supporting BIP-110 has risen to 2.38%

According to Cointelegraph, the number of Bitcoin nodes supporting Bitcoin Improvement Proposal 110 (BIP-110) has risen to 2.38%. This proposal is a temporary soft fork that limits the amount of data per transaction at the consensus level.

According to data from The Bitcoin Portal, out of 24,481 nodes, 583 are running BIP-110, with the main node software implementation for this soft fork proposal being Bitcoin Knots. BIP-110 limits the size of transaction outputs to 34 bytes and sets the OP_RETURN data limit to 83 bytes. According to the proposal's description on its GitHub page, this temporary soft fork will be deployed for 1 year, after which it may be extended or modified. OP_RETURN is a script code that allows users to embed arbitrary data.

Since the release of the latest version of the most widely used Bitcoin node software—Bitcoin Core 30—this feature has been a focal point of intense debate within the Bitcoin community. The OP_RETURN data limit was originally set to 83 bytes, but Bitcoin Core developers unilaterally removed this restriction in the Bitcoin Core 30 version. This change stemmed from a controversial code merge request first proposed in April 2025, which was widely opposed by the Bitcoin community.
