Bitcoin Core v30 has significantly increased the OP_RETURN data limit from 80 bytes to 100,000 bytes per output, allowing for larger on-chain data payloads. This update, which also permits multiple OP_RETURN outputs per transaction, has sparked a debate within the crypto community. Critics argue that the change could facilitate layer-1 metaprotocols and potentially increase transaction costs. However, supporters claim it modernizes data handling without affecting Bitcoin's monetary integrity. Analysts like Knut Svanholm have raised concerns about possible network abuse, while developers such as Jimmy Song view the change as a necessary technical advancement.
