On July 25, 2026, PlanB criticized the Bitcoin BIP-110 fork proposal, arguing that its supporters lack a clear understanding of node decentralization. The proposal introduces seven consensus rule changes over the course of a year, targeting on-chain data such as inscriptions and runes. It aims to reduce spam and node load by limiting script public key lengths and disabling certain Taproot paths. However, miner support stands at only 1%, far below the 55% threshold required. A final decision is expected after the signaling window opens around August 7–8.

BlockBeats news, on July 25, renowned analyst PlanB spoke out against the Bitcoin BIP-110 proposal: I oppose the BIP-110 fork. In my view, supporters of the fork do not truly understand three points: Bitcoin is a decentralized bearer asset; Bitcoin enthusiasts hate spam more than they do; and why the previous BCH fork failed.


BIP-110 is a temporary soft fork proposal that plans to introduce seven consensus restrictions over a one-year validity period, including limits on the length of new script public keys, partial push data and witness item sizes, and disabling certain Taproot extension paths, to significantly reduce the amount of arbitrary non-payment data—such as inscriptions and runes—that can be embedded in transactions, thereby lowering node burden, deterring spam data, and helping Bitcoin focus more on its role as money.


BIP-110 currently has only about 1% miner support, far below the 55% required for adoption, making its passage highly unlikely and nearly impossible to become an official rule on the Bitcoin mainchain. The final outcome will be determined after the mandatory signaling window opens around August 7–8.
