Quick correction: > Thus, the cost to perform the attack would be many orders of > magnitude greater than the cost to back up one channel. This was written assuming the attacker was trying to upload multiple encrypted blobs for the same txid, which seems like an unlikely attack vector if the

Re: [Lightning-dev] Trustless Watchtowers

Hi ZmnSCPxj, I haven't yet gotten around to writing up everything documenting in the working watchtower design. However, I think we are nearing that phase where things seem mostly solidified and would welcome feedback before attempting to formalize it. Expect some follow up posts on the ML :) >

[Lightning-dev] Trustless WatchTowers?

Hi all, Nicolas Dorier was requesting additional hooks in c-lightning for a simple WatchTower system: https://github.com/ElementsProject/lightning/issues/1353 Unfortunately I was only able to provide an interface which requires a *trusted* WatchTower. Trust is of course a five-letter word and
