Bitcoin Core 30 to raise default limit for non-financial data

Bitcoin Core version 30, scheduled for release in October, will raise the default limit for non-financial data in transactions to nearly 4MB, up from the 80-byte OP_RETURN cap, according to Protos. While node operators can still adjust this manually, the change is intended to support broader use cases for Bitcoin. Some developers, including Luke Dashjr and BitcoinMechanic, have expressed concerns that it could increase network strain and shift Bitcoin’s focus away from its original design.
