Okay, so the second worry i have about ecash over Liquid (has nothing to do with the code of either, just the real-world implementation) I'm worried the (location of) people who make up the federation of the the fedimint multisig aren't going to picked adversarially enough.
Obi (from Fedi) said (On Bitcoin Takeover Podcast) he pictured Fedimint custodians as trusted leaders of towns and villages. Soooo, all in the same jurisdiction? Huge risk from nation-states.
Compare this with Liquid having established businesses with skin in the game spread across the globe in multiple jurisdictions.
So best case, Fedimint custodians are spread out like Liquid's blocksigners
worse case,
they are literally neighbors in a small village.
