Bitcoin Core 30 Update to Raise Limit on Controversial OP_RETURN
- Bitcoin Core developers announced in May 2025 that version 30, releasing on October 30, will remove the 80-byte OP_RETURN data limit.
- This change follows years of debate between progressive developers advocating for increased data capacity and conservatives opposing non-monetary data storage.
- The update will raise the OP_RETURN limit to nearly 4MB per output, allowing significantly more arbitrary data to be embedded in Bitcoin transactions.
- Supporters argue the change reduces harmful off-chain data storage and censorship, while critics warn it risks blockchain bloat and deviates from Bitcoin's economic purpose.
- The update marks a major shift that likely expands Bitcoin's functionality but intensifies tensions over preserving its original design and decentralization.
