Bitcoin Core may remove OP_RETURN 80-byte limit in next upgrade

2025-05-07 05:24

Odaily News According to a developer statement, the next version of Bitcoin Core may remove the 80-byte limit on OP_RETURN outputs.
It stated that the 80-byte upper limit of OP_RETURN is no longer suitable for current needs, and many private mining accelerators no longer enforce these restrictions, which will also form a distorted incentive mechanism.
