Bitcoin’s Big Data Fight: Why a Proposal Almost No Miner Wants Still Matters
BIP-110 wants to cap non-money data on Bitcoin. Almost no miners back it, but Saylor and Back warn the fight itself is risky.
A proposal that would temporarily choke off non-financial data on the Bitcoin blockchain is barreling toward an early August deadline — and almost nobody who actually runs the network wants it. Known as BIP-110, the plan has drawn public opposition from two of Bitcoin’s biggest names, Strategy founder Michael Saylor and Blockstream co-founder Adam Back, even as support from miners sits below 1%.
What BIP-110 actually does
Every Bitcoin transaction can carry more than just money. A feature called OP_RETURN acts like a small note field, letting people attach a bit of extra data to a transaction. There’s also a separate route where users can stuff larger chunks of raw data into the transaction’s script or witness sections — this is how things like Ordinals, “inscriptions,” and some token projects put images, text, or metadata directly on the Bitcoin blockchain.
BIP-110, officially called the Reduced Data Temporary Soft Fork, would dial that back for one year. It would shrink OP_RETURN to its old, smaller size, block most data chunks larger than 256 bytes, and restrict certain script formats that are mainly used to store data rather than move money. Supporters argue this keeps Bitcoin’s limited block space focused on payments and eases the load on the computers (“nodes”) that keep the network running.
Critics see it differently. To them, capping this kind of data turns what should be a simple technical housekeeping decision into a rule baked into Bitcoin’s consensus — the shared set of rules every participant must follow — effectively telling users which fee-paying transactions are “acceptable” and which aren’t.
Two Bitcoin heavyweights say no
Michael Saylor, whose company Strategy holds one of the largest corporate Bitcoin stockpiles in the world, publicly criticized the plan over the weekend, arguing it would convert a debate about spam into a consensus change that invalidates transactions that are currently perfectly valid and already paying fees. He posted that “there are 110 things more dangerous to Bitcoin,” a jab at the proposal’s number.
Adam Back, the Blockstream co-founder and inventor of the Hashcash system that inspired Bitcoin’s mining design, went further, warning that BIP-110 amounts to policing other people’s transactions. He cautioned that pushing the proposal forward could split the Bitcoin community and, in the worst case, fracture the network into a fork — two separate chains running under different rules.
Why the numbers matter more than the noise
Despite the intense online argument the proposal has generated, the actual support behind it tells a quieter story: both miner and node adoption remain stuck in the low single digits, with reported miner backing under 1%. In Bitcoin, changes like this only take effect network-wide if the overwhelming majority of miners and nodes adopt them. With support this thin, BIP-110 looks set to create, at most, a small minority chain running its own rules rather than a change that affects the entire Bitcoin network most people use.
That distinction matters for everyday holders. A true network-wide fork could, in theory, mean confusion over which chain is “real” Bitcoin, split balances, or exchange listing headaches. A minority fork with near-zero miner support, by contrast, is far less likely to disrupt the Bitcoin that’s actually priced on exchanges and held in wallets — it would simply exist as a niche offshoot most people never interact with.
What this means for your coins
For anyone holding Bitcoin, the direct impact right now is minimal — no funds are at risk simply because this proposal exists, and with adoption this low, a network-splitting event looks unlikely. The bigger takeaway is what the fight reveals: even a proposal framed as a simple anti-spam fix can turn into a heated argument over who gets to decide what Bitcoin is for, and how much control any single group — miners, developers, or big holders — should have over the rules everyone follows.
Bitcoin’s strength has always rested on the idea that no single company or person can unilaterally change its rules. BIP-110’s stalled support is, in a way, that system working as designed — but the debate is a useful reminder for holders to keep an eye on governance fights like this one, since they shape how flexible, contentious, or predictable Bitcoin’s future rules will be.
