The proportion of Bitcoin nodes supporting BIP-110 has increased to 2.38%

On January 25th, the number of Bitcoin nodes supporting Bitcoin Improvement Proposal 110 (BIP-110) has risen to 2.38%. According to The Bitcoin Portal data, out of 24481 nodes, 583 are running BIP-110, with the main node software implemented as Bitcoin Knots. BIP-110 limits the transaction output size to 34 bytes and sets the upper limit of OP-RETURN data to 83 bytes, which may be extended or modified after 1 year of deployment. OP-RETURN allows embedding of arbitrary data, and since the release of Bitcoin Core 30, this feature has sparked heated discussions in the community. The developers of Bitcoin Core once removed the OP-RETURN data cap in Bitcoin Core 30. This change was due to a code merge request made in April 2025, which was widely opposed by the community.
