Bitcoin is approaching a critical block height that could trigger one of the most contentious governance disputes in years, as debate intensifies around a proposed protocol change known as BIP-110.
The network is closing in on block 961,632, expected in early August 2026, where the proposal is designed to activate automatically if conditions are met. The measure would restrict non-financial data embedded in transactions, a move supporters say would reduce congestion but critics warn could fracture the network.
Proposal risks sparking network split
BIP-110 requires a 55% miner approval threshold and includes a node enforcement mechanism, raising concerns that it could split Bitcoin into competing chains. While backers argue the change would restore Bitcoin’s role as a settlement network by limiting data-heavy use cases like Ordinals and Runes, opponents say it threatens interoperability and could disrupt wallets and infrastructure.
Blockstream chief executive Adam Back called the proposal technically unsound, warning that pushing rule changes without broad economic consensus risks creating a minor, unsupported fork. He noted that unlike past upgrades such as SegWit in 2017, this effort lacks coordination across developers, miners, and major ecosystem players.
Developers warn of wallet disruption
Developer Jameson Lopp has also voiced strong opposition, highlighting the risk that nodes enforcing BIP-110 could reject certain transactions. That scenario could effectively freeze assets tied to specific wallets and introduce operational hazards across the network.
Critics further argue that filtering “undesirable” data opens the door to future restrictions, potentially targeting privacy tools or politically sensitive transactions, undermining Bitcoin’s neutrality. Supporters counter that the proposal is temporary, set to expire after one year, and narrowly focused on excessive data usage.
Support remains weak ahead of activation
Despite the heated debate, current data shows minimal adoption momentum. Miner signaling has been recorded at roughly 0.75%, far below the required 55% threshold, while node adoption has hovered in the single digits. These figures suggest that a sustained chain split remains unlikely.
Analysts say the episode is more likely to act as a governance stress test than a breaking point. Still, the approach of the activation block could drive short-term volatility as derivative markets adjust and infrastructure providers prepare contingency measures.
Platforms may pause services as precaution
If a minority of nodes moves forward with enforcement, exchanges and custodians may temporarily halt deposits and withdrawals to prevent replay attacks and protect funds. Such precautions are standard during contentious upgrades.
Past precedent indicates that liquidity and network activity typically consolidate around the dominant chain. The 2017 Bitcoin Cash split demonstrated how economic backing quickly determines the primary network, a dynamic now reinforced by the influence of ETFs and institutional flows.
While BIP-110 is unlikely to trigger broad operational disruption without wider support, its approach has reignited fundamental questions about how Bitcoin governs itself, and how far participants are willing to go to enforce changes to the protocol.
