As promised, I've published the code for the Nostr-Stealth. This protocol promises complete metadata privacy by utilizing a sort of mixer/channel for messages.

Currently, Nostr apps are rolling out an enhancement through NIP-24 (which has vanished from the repository, idkw). That standard doesn’t fully encrypt metadata so the relay can notify the recipient. This has been a topic of extensive discussion among the devs, and it was decided that this functionality is essential for them.

In the model I'm proposing, users don't monitor their addresses. Instead, they would monitor a channel, which could either be exclusively for them or used by others. An interesting point here: the more people in a channel, the greater the privacy level, described as P=1/n.

I developed this just over a ~month ago and was working on the client before publishing everything. Since time became a constraint, I'm now sharing the protocol. This is precisely as I described in Morning Crypto ##(?) (If anyone recalls the episode number, please share it here). 🤘
