Also, note how from a practical point of view, we'll need to add a new type of tx that's only valid in a specific block, or other miners will just reorg those anyone-can-spend outputs to steal them. It's not all that trivial to actually do that... you'd have to have a signature that commits to the non-segwit part of the coinbase outputs. Ugh. -- https://petertodd.org 'peter'[:-1]@petertodd.org
