The upcoming release of Bitcoin Core v30 will remove the 80-byte limit on the OP_RETURN function, which is used for storing non-financial data on the blockchain. This change has reignited a debate that began in 2010 when Satoshi Nakamoto introduced data storage restrictions. Critics argue that this move contradicts Bitcoin's original purpose, while proponents believe it could enhance the development of second-layer networks. The discussion has gained momentum in 2024 as corporate interest in on-chain data capabilities grows.
