There is effectively no risk to a non-upgrade accidentally mining a new invalid block itself, the only risk is that a non-upgraded miner could itself mine on top of an invalid block. You would have to intentionally modify the code to mine an invalid block which is not something that would be likely to happen accidentally. > > Kind of obvious, when you think about it. > > -- > Tom Zander > Blog: https://zander.github.io > Vlog: https://vimeo.com/channels/tomscryptochannel > _______________________________________________ > bitcoin-dev mailing list > bitcoin-dev@lists.linuxfoundation.org > https://lists.linuxfoundation.org/mailman/listinfo/bitcoin-dev
