Bitcoin Core developers have confirmed that the next version of the software will lift the long -standing restriction of 80 bytes on the transaction outputs OP_return.
The decision was concerned about cryptographic space, users, users have dissatisfied with the decision.
Op_return survived his goal
The information was relayed in a Github May 5 announcement By the Bitcoin developer, Gregory Sanders, who was reading:
“The next version of Bitcoin Core by Bitcoin Core will be, by default, relay and mine transactions whose OP_Turn outputs exceed 80 bytes and allow any number of these outings.”
Sanders explained that the limit of 80 bytes was originally a “soft signal according to which the block space should be used sparingly for the proof of non-payment of publication data”, but that it has now survived its usefulness.
Op_return is a type of Bitcoin transaction output which allows you to store small amounts of data on the blockchain. Unlike regular outings, they are essential and therefore do not contribute to the unat -spent transaction outputs (UTXO).
The developers have noted that many private mining accelerators already ignore the limit and that users often find bypass. Instead of stopping improper use, they started to integrate data in a more complex way, such as the manufacture of false public keys or the use of spending scripts to hide the data. This makes the network more difficult to manage and less effective.
Some have proposed to introduce black lists to stop these tips, but the developers rejected this idea. They argued that the black lists are not reliable, difficult to maintain and could even lead to innocent people to lose funds.
Sanders also said that the removal of the restriction does not weaken Bitcoin safety. Rules such as the unit blocking limit of 4 million weights and other guarantees remain in place. However, change brings some improvements, such as a cleaner UTXO set and more coherent behavior on the network.
He explained that the developers considered three options before making a decision: keeping the ceiling, raising it or completely withdrawing it. According to him, the third option received “broad, but not unanimous support”.
Community debate
The announcement began a debate in the cryptographic community. The Bitcoin nodes maintaining Luke Dashjr described withdrawal as a “total madness”. Bitcoiner Samson Mow said On X on May 5, users “can refuse to upgrade and stay on 29.0 or execute another implementation”, referring to the nodes.
Critics too supported that the proposal was introduced without an appropriate decision -making process. “I think that a thing is clear enough: there is no consensus at the moment on this number OP_Preturn,” said Marty Bent Marty Bent Marty Bent.
Meanwhile, Sanders defended the withdrawal of the ceiling as being aligned with the Bitcoin ethics of “minimum and transparent rules”.
Despite these insurances, the community still does not agree. “This marks a fundamental change in the direction of Bitcoin,” said a commentator on Github. “This is the biggest error that the nucleus can make at this stage,” added another.
