i've been working on indra for a year now. we have proof of concept in the implementation of the basic cryptographic protocols for source obfuscated routing as well as bidirectional (hidden service) routing, and the protocol comes built in with the ability to do paywalling on a time/bytes basis.

we have approached spiral about this, geyser gave us a 500eur grant about a year ago that helped me relocate to cambridge where i spent my time developing the base implementation and refining the spec.

have no idea how to get this thing to move forward any further at this point, it's hard to get a word in edgewise between all the metoo nostr client development, even a real utility, a git hosting system built on nostr is still without any funding, i'm working on some parts of the cryptography for that at the moment.

i'd be most grateful if people would have a look at what i've done (and the sponsor himself also did some work on the CLI parts of it, though they haven't been wired together. to be honest, it's got a bit of a problem we need to solve with using UDP and making it connectionless, because the network can easily get way too large for a source routing scheme.
