Bitcoin Core, the custodian of the Bitcoin main node client, has released version 30 of the protocol. According to the release notes, the update “includes new features, various bug fixes, performance improvements, and updated translations.”
Bitcoin Core v30 was a much-anticipated but controversial improvement because, in the opinion of many users and a significant number of developers, it gave them “permission” to run indefinite spam on the network.
“With the release of this new major version, versions 27. – About a week and a half after writing this memo, the admin Uncovers potential moderate and severe software vulnerabilities Follow a responsible disclosure process.
Bitcoin Core v30 introduces changes to the transaction sending policy in the peer-to-peer (P2P) communication system between nodes, new command line instructions, an experimental interface for Bitcoin mining in Stratum V2, and changes to software installation directories and legacy wallets (heritage) Bitcoin.
The most important changes occur at the transaction policy level. As reported by CriptoNoticias, Bitcoin Core has long been planning to increase the taxable data limit for the OP_RETURN field. The amount of data that can be embedded in a transaction increases to 100,000 bytes.
–data carrier size (opcode that sets the storage limit) is increased to 100,000 by default and the limit is removed (as the maximum transaction size is reached first). – Can be overridden with .Data carrier size=83 Reverts to restrictions that were in place in previous versions.

CriptoNoticias also notes that Bitcoin Core -datacarriersize=83. Nevertheless, The protocol maintainers turned back. This decision was made in the last days of Bitcoin Core v30 preparation.
Weeks and months ago, Bitcoin Core v30 caused, and continues to cause, concern among the most “purist” Bitcoiners who see Bitcoin as exclusively a financial network and a threat that is spam.
Thanks to this transaction policy update, these Bitcoiners will be able to send unhelpful and even pornographic images (perhaps May pose legal risks to node brokers), which diverts Bitcoin from its core purpose as a monetary system.
However, according to BitMex researchers, there may be a technical reason for lifting the OP_RETURN restriction. This measure helps keep the blocks compact (compact block), a suggestion introduced by developer Matt Corrallo, It’s working effectively.
“If you want compact blocks to work, you need a good model for what miners mine, so you may need to increase the OP_Return limit locally,” they conclude from BitMex.
