Dfns ships Givre, an optimized FROST threshold signature library for distributed cryptographic systems. The open-source implementation outperforms existing Rust threshold EdDSA implementations and supports Bitcoin BIP340, Stellar, Soroban, Solana, and Tezos. Now maintained by Lockness under the Linux Foundation Decentralized Trust.
Dfns released Givre, an optimized implementation of the FROST protocol for threshold Schnorr signatures. The library provides distributed key generation, manual and interactive signing modes, and trusted dealer support with secret key reconstruction. Performance benchmarks show it outperforms prior Rust implementations, excelling in ed25519 and secp256k1. Givre supports Bitcoin BIP340 signatures, integrates with BIP32 standards, and is compatible across Stellar, Soroban, Solana, Tezos, and other blockchains. Dfns open-sourced the project and transferred governance to Lockness, a Linux Foundation Decentralized Trust initiative, to encourage community involvement and support FROST standardization at NIST.
