Bitcoin Core developers have confirmed that the next software release will lift the 80-byte limit on OP_RETURN transaction outputs, leading to discussion among users.
Definition of OP_RETURN
OP_RETURN is a type of Bitcoin transaction output that allows for small amounts of data to be stored on the blockchain. These outputs are unspendable and do not contribute to unspent transaction outputs (UTXOs). Developers believe the original 80-byte limit served as a signal that block space should be used judiciously, but this rationale has since diminished.
Community Doubts
The announcement has prompted debates in the crypto community. Some members, such as Luke Dashjr, described the removal as 'utter insanity'. Others, including Samson Mow, pointed out that users can refuse to upgrade and continue using earlier software versions.
Developers' Perspective
Developers, particularly Gregory Sanders, emphasized that removing the restriction does not weaken Bitcoin's security. He noted that the case for this change was broadly supported by the discussion participants. Sanders pointed out that some deceitful data handling methods already disregard the limit, and lifting it could lead to more efficient network management.
The decision to remove the OP_RETURN limit represents a significant move for Bitcoin Core, raising many questions about the blockchain's future and its evolution. Discussions within the community continue.
