Today in Crypto: Saylor Rejects BIP 110, Warns Softfork Threatens Bitcoin’s Neutral Rules

Across major exchanges, strategy founder Michael Saylor published a lengthy essay Saturday rejecting BIP 110, a proposed Bitcoin softfork that would temporarily restrict several types of transactions carrying non-payment data.

Saylor’s essay lists 100 numbered arguments against the proposal, which he says amounts to using Bitcoin’s consensus rules to discourage a disputed but currently valid category of transactions.

He frames the piece as a critique of the proposal, not the developers behind it, and says he shares their underlying goals of affordable node operation and cheap payments.

BIP 110, titled the “Reduced Data Temporary Softfork,” reached Complete status on June 25, 2026, according to its Github listing.

That status means the authors have finished their planned work and recommend adoption.

It does not mean Bitcoin developers or node operators have agreed to activate it, and the BIPs repository itself states that publication does not establish community consensus.

The proposal would run for roughly one year and add seven new consensus restrictions.

These include an 83-byte limit on OP_RETURN outputs, a 256-byte cap on many pushed payloads and witness items, a ban on spending undefined witness and Tapleaf versions, a prohibition on the Taproot annex, a 257-byte cap on Taproot control blocks, and a rejection of certain Tapscript opcodes and branches.
