This would then lead to a chain-fork as the SW miners reject it and the non- SW miners continue to mine on 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
