1. Bifrost - Threshold Signing & Secure Messaging for Nostr - New Developer tool

Bifrost is a core library and SDK for implementing the FROSTR protocol, a threshold signing and secure messaging system for nostr. It provides a BifrostNode that communicates over nostr, enabling nodes to collaborate in signing messages and exchanging ECDH secrets. Bifrost supports standalone deployment or integration into existing nostr clients, offering methods for creating, distributing, and managing FROST based threshold signing shares. This enhances security and decentralization by ensuring no single party controls the signing process.

2. Nostringer – Unlinkable Ring Signatures for Nostr - New Developer tool

Nostringer is an easy-to-use Javascript/Typescript library providing unlinkable ring signatures (SAG) for Nostr pubkeys. It allows a signer to prove membership in a group of Nostr accounts without revealing which specific account produced the signature.

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 Leo Wandersleb (nprofile…nqad) 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.
