Odaily News The debate over Bitcoin's OP_RETURN has intensified as developers of Bitcoin Core, the most popular node software, said they plan to completely remove OP_RETURN in the next version. Core contributor Greg Sanders said on GitHub that the current 80-byte limit has failed to effectively prevent data abuse, but instead forced data to be embedded in transactions in a more covert way, increasing the burden on the network. He believes that removing the limit can simplify the UTXO set, improve system consistency, and allow the fee market to naturally adjust demand. Opponents such as developer Luke Dashjr criticized the move as "completely crazy", believing that it would encourage the spread of spam and deviate from Bitcoin's financial positioning. The adoption rate of the Bitcoin Knots node maintained by it has risen to 5%, and some opinion leaders have called on users to resist upgrades or switch to this version. Supporters emphasize that the simplification of rules is in line with the spirit of Bitcoin, but opponents warn that this is a "fundamental change in direction." The differences between the two sides highlight the deep contradiction between Bitcoin's functionality and decentralized vision, and consensus may be difficult to reach in the short term. (CoinDesk)
