Instead of creating a hodl invoice, we can use a regular invoice from a user's configured federation. A lightning gateway for that federation will be running 24/7 to settle the payment instantly and in an atomic way. Our LNURL Address server, called Blinded-Hermes, will create an ecash contract that spends to a pubkey-locked ecash note. We use the user's registered pubkey for this. Once the lightning gateway processes the payment, the federation will complete the contract and provide the user with the new ecash.
That's correct. It also helps with the receiver offline issue in general, so we prioritize that. You can always swap to your lightning channel at any time after receiving payments.
It's a nostr based discovery protocol for mints. You can independently view / list mints on https://bitcoinmints.com/ and it's interoperable with how Mutiny is pulling them in too.
As always Mutiny team keeps on knocking it out of the park. Great Job
Title doesn't mention it but also federations to helping with lightning address is in the article.
