A new Bitcoin fork proposal, potentially becoming BIP 444, aims to restrict on-chain data storage unrelated to Bitcoin transactions. Pseudonymous developer 'Dathon Ohm' has revived BIP 2017 to address concerns over Bitcoin Core v30's relaxed rules on OP_RETURN data. The proposal includes proactive and reactive activation methods, with the latter allowing miners to block illegal content immediately. The proposal has sparked debate within the community, with critics warning that the reactive method could lead to legal pressure on miners. Some have attributed the proposal to Core developer Luke Dashjr, although he has denied any involvement.
