Foundry USA, the largest Bitcoin mining pool, asks clients to vote on BIP-110, a proposal to limit transaction data and curb Ordinals inscriptions. Vote closes at block 961,632.
Foundry USA, the largest Bitcoin mining pool by hashrate, asked its clients to vote on how the pool should signal support for Bitcoin Improvement Proposal 110. The proposal is a soft fork that would cap the amount of data a single Bitcoin transaction can carry, a move aimed squarely at Ordinals inscriptions and other non-financial uses of the network.
Foundry distributed educational materials alongside the vote request. The voting window closes at Bitcoin block 961,632, expected in early August. Pool clients received a link via email to cast their ballots.
BIP-110 is one of the most contentious proposals in the Bitcoin ecosystem right now. Adam Back, CEO of Blockstream and a prominent figure in Bitcoin's development, came out strongly against it. He warned the proposal could be used to freeze user funds. Michael Saylor, executive chairman of Strategy, also criticized BIP-110, noting it could invalidate ordinary transactions on the network.
The opposition from figures with historical and technical weight shows how deep the debate runs. The question is not just about technical limits but about whether the protocol should judge the intent of transactions.
Foundry controls roughly 23.8% of total Bitcoin network hashrate, according to Hashrate Index. That makes its stance on BIP-110 a big factor in the outcome of the vote. If Foundry signals support, the proposal gains a critical mass of mining power. If it opposes, BIP-110 likely stalls.
The debate is also playing out across the broader crypto market. Crypto derivatives volume has dwarfed spot volume 4.4x, according to a recent Cboe report, highlighting how the market's center of gravity is shifting toward institutional trading tools. BIP-110's outcome could affect how those tools interact with the Bitcoin base layer.
For miners, the decision is practical. Capping data per transaction reduces block space competition from Ordinals, which could lower fee revenue but also stabilize transaction costs. For institutional investors, the proposal raises questions about Bitcoin's fungibility and the precedent of protocol-level content restrictions.
The vote closes at block 961,632. No date for a final decision has been set beyond that.
