A significant dispute among Bitcoin developers regarding the OP_RETURN function could potentially lead to a hard fork. The conflict arises from differing views on whether to limit the embedding of arbitrary data in Bitcoin transactions. Concerns have been raised that such data could transform the network into a storage layer for harmful content. The recent increase in the OP_RETURN limit from 80 to 100,000 bytes in Bitcoin Core v30 has sparked controversy. Developer Dathon Ohm has proposed BIP-444, which seeks to temporarily restrict data storage at the consensus level to mitigate legal risks for node operators. However, critics argue that this proposal could compromise Bitcoin's censorship-resistant principles. Prominent developers caution that a lack of consensus on this issue could lead to a network split.
