BIP-110 Fork Stalls After Two Blocks: Where Is Bitcoin's "Junk Data" Debate Headed?

§ 01 Executive Snapshot

• What: BIP-110, a proposed Bitcoin upgrade, stalls after producing only two blocks, failing to gain miner support.
• Who: Key players include Dathon Ohm, Luke Dashjr, Michael Saylor, Adam Back, and the mining pool OCEAN.
• Why it matters: The failure of BIP-110 highlights ongoing debates about Bitcoin's governance and the future of on-chain data usage, potentially impacting Bitcoin’s consensus rules and market stability.

§ 02 Key Developments

• As of August 9, 2026, the mandatory signaling period for BIP-110 began, but only two blocks were produced before the branch stalled.
• During the difficulty adjustment period prior to signaling, only 51 blocks (2.53%) signaled support for BIP-110, falling short of the 55% threshold needed for voluntary early lock-in.
• The proposal includes seven consensus restrictions aimed at limiting the amount and type of data inscribed on the Bitcoin blockchain, particularly targeting the usage of Ordinals inscriptions.

§ 03 Strategic Context

• BIP-110's introduction follows the release of Bitcoin Core 30.0 in October 2025, which relaxed the OP_RETURN relay limit, igniting debates about data usage on the Bitcoin blockchain.
• The failure of BIP-110 reflects broader tensions within the Bitcoin community regarding how to manage on-chain data and uphold Bitcoin's decentralized ethos, especially in light of competing proposals like DOG Mode.

§ 04 Strategic Implications

• The immediate consequence of BIP-110's failure is a likely reaffirmation of the status quo regarding on-chain data, as the main Bitcoin chain retains overwhelming miner support.
• Long-term, the debate may lead to new proposals addressing on-chain data management, requiring significant coordination among stakeholders to gain acceptance.

§ 05 Risks & Constraints

• A major risk is the lack of built-in replay protection in the minority chain, which could lead to unintended transactions on the main Bitcoin chain.
• Competition among proposed solutions, such as DOG Mode, may fragment the community further and complicate consensus on future upgrades.

§ 06 Watchlist / Forward Signals

• Future developments will be signaled by any new proposals aimed at modifying Bitcoin's consensus rules regarding on-chain data, particularly if they gain broader support across the community.
• Monitoring the reactions of major mining pools and stakeholders will indicate the viability of alternative proposals and the potential for future consensus changes.
