Bitcoin Core developers have decided to remove the limitations on transaction data in the next network upgrade, allowing for more data to be included. This change has sparked controversy, with some believing the proposal did not undergo the proper Consensus process. OP_RETURN allows for the storage of a small amount of data in transaction outputs and became popular during the Bitcoin ordinal craze.

On May 6, Bitcoin Core developers decided to remove the limit on transaction data in the next network upgrade, allowing for a more efficient way to include more data. 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 for transactions over 80 bytes and will allow for any number of outputs.” Critics have responded that the proposal was made without proper consensus procedures. Marty Bent, managing partner at Ten31 Fund, stated: “There is currently no consensus on the OP_RETURN issue.” It has been reported that OP_RETURN allows for transaction outputs that store a small amount of data on the blockchain, gaining popularity during the Bitcoin ordinal craze in early 2024. Unlike regular transaction outputs, OP_RETURN outputs are unspendable and do not increase the Unspent Transaction Output (UTXO). (Cointelegraph)
