best/latest FEDIMINT re-summary. THANKYOU! proof-of-punch. like it. layer? i vote it's layer 1.5 .. why? 'cause lightning (layer 2) is not really auditable, where-as the possibiity of 'periodic attestation' with fedi (etc) is even closer to on chain [proof of reserverves]. as for key/mint epoch's ... you little beauty ... you've done it. BRAVO!

Awesome work! Have already seen someone asking for a Cashu mint in the Baltic Honeybadger 2023 Telegram group. Would love to see ecash in action and actually use it at a conference
