Introducing Nostringer - unlinkable ring signatures (SAG) for Nostr pubkeys.
Instead of doing some Ghibli stuff I implemented a prototype of unlinkable ring signatures for Nostr.
It's using Monero style Spontaneous Anonymous Group signatures (SAG).
What does it enable ?
Ring signatures allow multiple members of a group to sign a message without revealing which member actually signed it.
I explored this after chatting with nostr:nprofile1qqsydl97xpj74udw0qg5vkfyujyjxd3l706jd0t0w0turp93d0vvungpzpmhxue69uhkummnw3ezumt0d5hszythwden5te0dehhxarj9emkjmn99ujcnqad who wants to use this concept for WalletScrutiny. Basically his idea would be to let users write reviews as accredited wallet developers. Because of the competition between wallets it's better to not disclose who posted a review.
It would be sufficient to know that it was posted from someone belonging to a group of accredited developers.

Cool!
I have a draft ring signature NIP — I’d be curious to hear your thoughts Abdel and Leo whether this NIP would be useful with Nostringer. If so I’ll submit it as a PR for discussion.
Just submitted this as a PR as NIP-97: Ring Signatures
Bookmarked!
Yes I believe so
