The first Bitcoin block to support BIP-110 has appeared, sparking controversy over restrictions on the use of on-chain data.

The Bitcoin community is once again embroiled in controversy over a proposal to limit on-chain non-financial data, with the mining pool Ocean having mined the first block marked as supporting BIP-110. This proposal, which has been in development for about a year, aims to tighten restrictions on transaction output size and arbitrary data fields through a temporary soft fork, in order to reduce the block space occupied by non-financial data such as inscriptions and OP_RETURN. Supporters argue that this will help maintain Bitcoin's position as a monetary infrastructure and reduce the burden on nodes; opponents warn that intervention at the consensus layer could compromise network neutrality and increase the risk of forks.
