It walks through trusted-dealer key generation, Round 1 nonce commitments, Round 2 signature shares, and final aggregation into a standard Ed25519 signature. The protocol solves single-key concentration risk by requiring any threshold subset of participants to sign without reconstructing one private key. This is an asymmetric threshold-signature security model.\n\n## When to Use It\n- Use this when one account or service key should require multi-party approval, because threshold signing removes single-custodian control.\n- Use this for distributed key custody in teams, because FROST allows any t-of-n subset to produce one normal verifier-facing Ed25519 signature.\n- Use this when you need signer availability under partial outages, because signatures can still be generated if enough participants are online.\n- Do not use this when one signer must act instantly without coordination, because FROST signing requires participant interaction across rounds.\n\n## Live Demo\nOpen the live demo at https://systemslibrarian.github.io/crypto-lab-frost-threshold/.\nYou can set participant count n and threshold t, generate shares, run Round 1 and Round 2, and aggregate the signature for verification. The interface also includes message input and a simulate-failure control to demonstrate invalid aggregation when insufficient shares are provided.\n\n## How to Run Locally\n```bash\ngit clone https://github.com/systemslibrarian/crypto-lab-frost-threshold.git\ncd crypto-lab-frost-threshold\nnpm install\nnpm run dev\n```\n\nNo environment variables are required for local development.\n\n## Part of the Crypto-Lab Suite\nThis project is part of the broader crypto-lab collection at https://systemslibrarian.github.io/crypto-lab/.\n\nSo whether you eat or drink or whatever you do, do it all for the glory of God. - 1 Corinthians 10:31\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsystemslibrarian%2Fcrypto-lab-frost-threshold","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fsystemslibrarian%2Fcrypto-lab-frost-threshold","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fsystemslibrarian%2Fcrypto-lab-frost-threshold/lists"}
