Woofun AI reports that Adam Back and Michael Saylor have publicly opposed the BIP 110 proposal. Back argued that using consensus mechanisms to restrict behavior violates Bitcoin's core principles of decentralization and permissionlessness, noting that the existing technical consensus acts as an efficient immune system against unvalidated changes. Saylor added that the proposal risks rendering currently valid transactions invalid, transforming a spam dispute into a dangerous consensus precedent. BIP 110 aims to modify default relay strategies to filter on-chain data like OP_RETURN outputs to curb spam.
