Michael Saylor's recent promotion of Bitcoin Knots has sparked renewed debate over the OP_RETURN data limit change in Bitcoin Core v30. The clip, which included a call to 'Run Knots,' has intensified discussions among Bitcoin Core developers, node operators, and Bitcoin Knots supporters about the implications of increasing the OP_RETURN limit from 80 bytes to 100,000 bytes. The debate centers on potential impacts on network performance, storage requirements, and client choice. Critics warn of possible network congestion and misuse, while proponents argue for new on-chain use cases. Node operators are encouraged to test the changes and assess resource impacts before deciding on upgrades.
