PANews reported on June 10 that according to Protos, the Bitcoin Core Development Team announced that it will modify the default settings of OP_RETURN in the Core 30 version released in October, raising the upper limit of data carriers from 80 bytes to nearly 4MB. This decision marks a phased victory for the reformists led by Antoine Poinsot in the long-term dispute with conservatives such as Luke Dashjr.

Although the new version still allows node operators to manually restore the smaller data limit, analysis shows that most nodes will keep the default settings. Conservatives criticized this move for violating the original design of Bitcoin as a value transfer network and may reduce the blockchain to a data storage platform. Reformists believe that moderate expansion will help expand Bitcoin's functions and have made compromises to allow parameter adjustments. The change is expected to affect the on-chain data storage ecosystem, but will not change Bitcoin's basic transaction verification mechanism.
