Foundry USA, one of the largest Bitcoin mining pools, has asked its customers to signal whether they support BIP-110 — a proposal that would reduce the amount of data that can be stored in a Bitcoin transaction. The request, sent to miners this week, is an early test of appetite for a change that could reshape how the network is used.
What BIP-110 would change
BIP-110 targets the data payload that can be attached to a Bitcoin transaction. Right now, there's no hard limit on how much extra data you can stuff into a transaction — think images, text, or other files. The proposal would cap that, effectively limiting the blockchain's use as a storage layer for non-financial content. That's a direct hit at the kind of data-heavy inscriptions that have clogged blocks in recent years.
Foundry's role and the signal
Foundry isn't making a decision on its own. It's asking the miners who point their hashpower at the pool to signal their stance. This isn't a binding vote — more like a temperature check. But given Foundry's share of the network's hashrate, the results will carry weight. If a majority of its customers say yes, it could push the proposal toward broader adoption. If they say no, BIP-110 might stall.
Why now
The timing isn't random. Bitcoin's block space has been a battleground for years, with some arguing that non-transactional data degrades the network's primary function as a payment system. Others see it as a feature, not a bug. Foundry's move suggests the debate is heating up again. The pool is effectively asking miners to pick a side.
What happens next
Miners have been given a window to submit their signals. Foundry hasn't announced a hard deadline, but the results are expected to be tallied in the coming weeks. If BIP-110 gains enough support, it could move to a formal BIP process and eventually a network upgrade. If not, the proposal likely fades. Either way, the signal will show where the mining community stands — and that alone could shift the conversation.
