Naturally, I fully agree. It seems I choose the wrong words, let me rephrase; You can't roll the SegWit back a week after people are allowed to send segwit transactions (lock-in + fallow period). All transactions that were made in the mean time turn into everyone-can- spent transactions. Because the network as a whole and any implementation is unable to roll back in an environment where SegWit is a contriversial soft-fork, it is super important to make sure that it is properly supported by all miners. This takes time and the risk you take by pushing this is that actual real people loose actual real money because of the issue I outlined inthe previous paragraph. > Having 2 months or 2 weeks of grace period > makes totally no difference in this regard.

I hope the above explains the actual security issue better. -- 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
