As Yakko and Wakko used to say: Helloooooo Knots!
So far so good.
Though I must note that neither the bitcoind nor bitcoind-knots Nix packages (in Nixpkgs) have any kind of signature verification process. The Electrum package has verification in their updater script, and the Bisq 2 and Sparrow packages have build-time verification. I may need to roll up my sleeves and do something about this.
