This means SPV clients (assuming they only connec= +t to honest/trusted nodes) work as-is. + +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 sig= +ning a reorg every few blocks, allowing users to choose the behavior they w= +ant. + +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. + |
