According to Mars Finance, on May 6, Bitcoin Core developers have decided to remove restrictions on transaction data in the next network upgrade, allowing for more data to be included in a more efficient manner. Bitcoin developer Greg Sanders announced on GitHub on May 5: "The next version of Bitcoin Core will default to relaying and mining OP_RETURN outputs larger than 80 bytes, and will allow for an arbitrary number of outputs." In response, critics have stated that the proposal was made without proper consensus procedures. Ten31 Fund managing partner Marty Bent said: "Currently, there is no consensus on the OP_RETURN issue." It is reported that OP_RETURN allows transaction outputs that store a small amount of data on the blockchain, which became popular during the Bitcoin ordinal craze in early 2024. Unlike conventional transaction outputs, OP_RETURN outputs are unspendable and do not increase unspent transaction outputs (UTXO). (Cointelegraph)
