Okay i didn’t realise your sketch didn’t require changes to the mint software. I was thinking about it more like UTXOs where each spend is a UTXO and the service provider can redeem these UTXOs. But it’s similar to what you guys have proposed.
This would be great for Routstr by the way. We will be able to perform 100s of requests without being rate limited by the mints.
One advantage the UTXO design would have is that the service provider wouldn’t need to interact with the mint to verify that the channel is opened (cuz mint’s pubkey signs the message) but i guess we can do this by adding it to the spec you guys have proposed.
