Foundry's BIP-110 Vote Tests Miner Consensus

Foundry USA, the world’s largest Bitcoin mining pool by hashrate, has opened a hashrate-weighted vote on whether to signal support for BIP-110, a proposal to temporarily restrict non-financial data in Bitcoin transactions and potentially curb Ordinals. The voting window runs through early August 2026 and signals are counted such that non-responses count as No, with Foundry only switching to a “Yes” signal if supporters exceed 51% of participating hashrate. Currently, miner support is very low, with signaling under 1%, meaning activation remains unlikely in the near term despite Foundry controlling roughly a third of global hashrate. Proponents argue BIP-110 could improve block-space dynamics by limiting non-payment data, while critics, including Blockstream’s Adam Back and MicroStrategy’s Michael Saylor, warn the measure could have unintended consequences or invalidate ordinary transactions. The outcome of Foundry’s vote could influence the broader mining and development community, given its substantial share of hashrate and the data-cap debate’s implications for fees and block usage. Foundry’s initiative also highlights how miner economics and fee markets intersect with governance, as Ordinals and related protocols have crowded Bitcoin’s block space and intensified calls for data-control measures.
