Michael Saylor, one of Bitcoin's most vocal advocates, has publicly opposed the proposed BIP-110. The plan would temporarily block what its backers call 'spam' data from the Bitcoin blockchain. Saylor argues the move would undermine the network's neutrality and set a dangerous precedent for censorship.
What BIP-110 would do
The proposal aims to filter out certain transactions deemed spammy — think tiny amounts or repetitive data blobs. Supporters say it would reduce congestion and lower fees. But critics, including Saylor, see it as a slippery slope. Once you start picking which data is allowed, where do you stop?
Saylor's argument
Saylor didn't mince words. He said BIP-110 would break the core promise of Bitcoin: that no one gets to decide what's valid beyond the consensus rules. In his view, even a temporary filter creates a mechanism that could be abused. The network's strength is its permissionless nature. Tinker with that, and you risk turning Bitcoin into something else entirely.
The timing
The debate comes as Bitcoin's blockspace has gotten more expensive. Some users are frustrated by spam-like transactions. But Saylor's stance is a reminder that short-term fixes can have long-term costs. The proposal hasn't been adopted yet, but it's being discussed in developer circles. Saylor's opposition adds weight to the anti-censorship side.
BIP-110 is still a proposal. It needs community consensus to move forward. Saylor's public opposition doesn't kill it, but it forces a harder conversation. The Bitcoin community now has to decide: is a cleaner mempool worth the risk of a less neutral network?
