Nearly complete draft of Indra Protocols:

https://github.com/indra-labs/indra/blob/9-architecture-of-relay-engine/docs/protocols.md

Posting to share the state of this part of the work that I am engaged in at the moment.

The lack of diagramming tooling in Github means that you see the rubbish PNG version of the diagrams, which the boxes have opaque, overlaying backgrounds, but the PNG generator doesn't render the damn things.

I will look for a better solution for diagrams but I just wanted this document to be semi-decent for people to see. I have dropped the link on the Lightning Network mailing list because I think it might help them create a fully receiver side anonymity protocol.

I am always paranoid about building my work to be brittle, but it seems to me that the Lightning Network Protocol is a little less formalised than it appears or might be expected to be. Similar also Nostr.

For sure, the most widely used LN implementation, LND... yeah... holy crap what a bug festival. Try messing around with the configuration system to discover how many things don't actually work.

Anyhow, step 1 and 2 of the hidden service protocol can equally enable a mechanism for proxied inbound payments on Lightning Network. Just switch a few labels around and it's the same thing.
