Bitcoin Developer Prepares Emergency Code as BIP-110 Faces Miner Resistance

As the Bitcoin network debates the fate of BIP-110, a proposal designed to limit non-monetary data on the blockchain, developer Chris Guida has prepared a contingency plan. According to Bitcoin News, Guida has reworked the 2017 proof-of-work (PoW) change code so it is compatible with the latest version of Bitcoin Knots, a full-node implementation. The code is intended as a fallback if major mining pools do not support the soft fork, allowing the network to enforce the proposed rules even without miner cooperation.

Background on BIP-110

BIP-110, or Bitcoin Improvement Proposal 110, seeks to reduce the amount of data that can be stored in Bitcoin transactions. The proposal specifically targets non-monetary transactions, including those associated with Ordinals, a protocol that lets users inscribe data onto satoshis and effectively create NFTs on the Bitcoin blockchain.

Supporters of the proposal argue that such transactions add unnecessary strain to the blockchain and move Bitcoin away from its intended role as a peer-to-peer electronic cash system. The proposal has drawn debate across the community, with some miners and node operators raising concerns about its implications for network scalability and user freedom.

Emergency PoW Change as a Backup Plan

Guida’s work centers on updating code for a proof-of-work change, which would alter the mining algorithm and, in effect, replace the existing mining network if major mining pools refuse to support BIP-110. The idea is not new. It was previously discussed in 2017 as a possible mechanism for enforcing user-activated soft forks (UASF).

Luke Dashjr, a prominent Bitcoin Core contributor, said he hopes the measure will never be necessary, but stressed the importance of preparation. In verbatim English, he said: “만약의 사태에 대비해 미리 준비해 두는 것이 좋다” (It’s good to prepare in advance for contingencies).

Supporters, including a developer known as Mechanic, have backed the preparation of such code. They argue that a credible PoW change threat is needed to ensure miners fulfill their responsibilities to node operators rather than unilaterally determining Bitcoin’s rules.

Why the Debate Matters

The dispute highlights a core tension in Bitcoin governance: the balance of power between miners, who secure the network, and node operators, who validate transactions.

If miners reject BIP-110, the contingency code could trigger a chain split, creating two competing versions of Bitcoin. For users, that could mean uncertainty, possible replay attacks, and market volatility. Supporters of the PoW change argue that it would provide a necessary check on miner power and help keep the network aligned with the consensus of node operators and users, rather than only the interests of mining pools. That makes the current debate less about a single proposal than about how Bitcoin changes are ultimately enforced when parts of the network disagree.

Community Reaction

Reaction to Guida’s announcement has been mixed. Some community members see it as a practical step to protect the network’s integrity, while others worry that it could deepen divisions within the Bitcoin ecosystem.

The debate over BIP-110 and the contingency plan reflects a broader philosophical split within Bitcoin over its future direction. As the network evolves, the outcome could influence how protocol changes are enforced and could have lasting effects on Bitcoin’s scalability and usability.

Conclusion

Chris Guida’s preparation of PoW change code for Bitcoin Knots underscores that Bitcoin governance is not only technical but also political. Even if the contingency is never used, its existence signals that some developers are prepared to take drastic measures to defend their vision for Bitcoin.

For now, the community is waiting for miners to decide the fate of BIP-110, with the result potentially shaping the network for years to come.
