Since Bitcoin Core builders started proposing a controversial enhance to the information storage capability of a Bitcoin script operation code, the variety of node operators protesting that change has hit an all-time excessive.
Web-connected full nodes propagating Knots-tagged blocks that reject the proposed elevated knowledge restrict have doubled for the reason that OP_RETURN warfare started final month.
On April 17, Chaincode Labs’ Antoine Poinsot reintroduced Peter Todd’s pull request (PR) 28130 that requested Core contributors to carry the roughly 80-byte restriction on the datacarrier restrict OP_RETURN outputs.
As Core contributors indicated their willingness to proceed with the change, software program downloads of an alternate full node consumer, Knots, skyrocketed.
As disagreements divided the Bitcoin group, Peter Todd finally formalized the request as PR 32359. Regardless of dozens of reviewers voting “NACK” — shorthand for “negative acknowledgement” — Blockstream engineer and Core contributor Greg Sanders wrote that Core was planning to implement PR 32359 inside a number of days.
Knots’ default mempool is not going to carry the datacarrier restrict of OP_RETURN, it doesn’t matter what Core decides. Due to this fact, the expansion of reachable Knots nodes — which reached an all-time excessive of 6.5% yesterday, in accordance with tracker Coin.dance — is a proxy for measuring the resistance motion.
Company pursuits versus Bitcoin’s preeminence
For the bigger knowledge restrict camp, growing OP_RETURN’s datacarrier merely normalizes its on-chain knowledge storage limits with different methods to retailer arbitrary knowledge in bitcoin transactions, corresponding to witness outputs.
Eradicating OP_RETURN’s 80-byte cap is an easy, unremarkable improve, in accordance with their rhetoric.
For the smaller knowledge restrict camp, a lot of whom run Knots, the proposal is proof that Bitcoin Core builders are succumbing to company and enterprise capital pursuits in utilizing Bitcoin’s largest mempool as a distributed database.
Permitting simpler proliferation and validation of pictures, music, video games, contracts, and non-transactional knowledge is a slippery slope that undermines bitcoin’s major goal of displacing fiat.

Choice time for Bitcoin’s 2025 OP_RETURN warfare
A serious convention of Bitcoin builders is beginning in the present day in Austin. The primary subject of debate will likely be PR 32359 and mempool coverage, with a remaining resolution on the proposal anticipated momentarily.
New feedback are arriving by the hour on the Bitcoin-Dev mailing record, GitHub, StackerNews, and X.
Bitcoin full node operators might select any software program consumer they want to validate and propagate transactions. Core is by far the dominant model with 19,662 reachable nodes as of publication time, whereas Knots is the second-most widespread consumer at 1,464.
Different purchasers embody btcd, Bitcore, and UASF.
Though there are tons of of 1000’s of full node operators on this planet, it’s unimaginable to quantify what number of full nodes truly exist. Bitcoin is purpose-built to accommodate nodes with intermittent web entry, and nodes are free to hitch and depart the community at any second.
Reachable node trackers like Coin.dance, Bitnodes, or Clark Moody use varied sorts of web monitoring instruments to estimate the variety of nodes which are reachable at any given second.
