I'm going to look into revising and completing it soon, and would welcome any suggestions for doing so. This hardfork BIP aims to accomplish a few important things: - Finally deploying proper merge-mining as Satoshi suggested before he left. - Expanding the nonce space miners can scan in-chip, avoiding expensive calculations on the host controller as blocks get larger. - Provide a way to safely deploy hardforks without risking leaving old nodes vulnerable to attack. https://github.com/luke-jr/bips/blob/bip-mmhf/bip-mmhf.mediawiki Luke
