You’re correct that Core v30 didn’t change the OP_RETURN limit itself, only the default relay policy. However, as a node operator, I’m free to enforce stricter policies locally, and I intend to. I don’t want to relay or store larger OP_RETURN transactions because: 1. Legal risk: Hosting or relaying arbitrary on-chain data (especially CASM content) is illegal under EU law when it includes copyrighted or illicit material. As a node operator in the EU, I have a legal obligation to minimize exposure to such data. 2. Network efficiency: Larger OP_RETURN payloads bloat the UTXO set and mempool bandwidth without contributing to Bitcoin’s core purpose, financial settlement. 3. Principle of minimalism: Bitcoin’s design goal is censorship resistance for money, not a general-purpose data storage system. Keeping relay policies tight preserves the network’s scalability and neutrality. So while Bitcoin Core’s position is about maintaining realistic relay behavior, my stance as an operator is simple: my node, my policy. I will not relay or store CASM or any non-financial payloads. Don’t care if it’s Core or Ocean propaganda, try to apply common sense.
