From jlspc at protonmail.com Mon Dec 26 19:18:38 2022 From: jlspc at protonmail.com (jlspc) Date: Mon, 26 Dec 2022 19:18:38 +0000 Subject: [Lightning-dev] Factory-Optimized Protocols For Lightning In-Reply-To: References: Message-ID: I'd like to make two corrections to this post: 1) The link for reference [8] should be: https://lists.linuxfoundation.org/pipermail/lightning-dev/2022-February/003479.html (thanks to David A. Harding for this correction). 2) An extension of the FFO protocol was described in which the parties in a channel could continue to operate the channel after one party put their State transaction on-chain by having the first output of that State transaction play the role of the same party's Individiual transaction's output. This doesn't work, because that party would have to reveal the per-commitment key to invalidate the previous channel state, and once revealed the other party could then spend that output. This problem can be fixed by having the party that put their State transaction on-chain put a new Individual transaction on-chain that spends the first output of their State transaction.
