Keeping the PoW rule and moving the signature would mean DoS attacks would be trivial as anyone could mine blocks without a signature in them, unless you ramped up the difficulty, which would mean it's just another testnet. It's a test network, admittedly, but I think it would kind of defeat the purpose. > A previous idea regarding reorgs (that I believe Greg came up with) is to > allow multiple keys to sign blocks, with one signing no reorgs and one > signing a reorg every few blocks, allowing users to choose the behavior they > want. Not sure how this would work in practice. The idea with signet is to have an actual network that is occasionally reorged, i.e. it's a global network (for those participating) that everyone agrees on. Not sure how you would have choices there. _______________________________________________ bitcoin-dev mailing list bitcoin-dev@lists.linuxfoundation.org https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
