The upcoming technical update from the Bitcoin Core team has sparked debates within the community regarding its core value of decentralization and future direction. The Bitcoin Core 30 update, scheduled to go live on October 30, 2025, includes a significant adjustment to the OP_RETURN functionality data storage limit, which aims to greatly enhance the capacity for non-financial data on the blockchain. This has raised deep concerns among conservatives about potential inflation of the blockchain and the positioning of Bitcoin as a 'sound currency'.

The crux of the issue lies in the planned removal of the current 80 bits character limit for the OP_RETURN functionality in the Bitcoin Core 30 update (expected to be released on October 30, 2025), which will allow up to 4MB of character data per transaction input.

This decision stems from the support of 31 Bitcoin Core developers who signed Merge Pull Request MPR #32406. The developers emphasized that this is an adjustment to the relay policy, not a change to consensus rules. In simple terms, it is an optional feature, and miners and node operators can independently decide whether to process such transactions.
