BLS Signatures Playground
BLS (Boneh–Lynn–Shacham) signatures are short, secure digital signatures that support aggregation. Used in Ethereum 2.0 (validators), threshold cryptography, and zero-knowledge systems.
How BLS Signatures Work
- Generate a key pair (private and public).
- Sign a message using the private key.
- Anyone can verify the signature with the message and public key.
Ethereum uses BLS to allow validators to sign blocks with lightweight, aggregatable proofs.
Why BLS is special
- Signature aggregation: many signatures → 1 compact proof
- Used in proof-of-stake consensus (Ethereum Beacon Chain)
- Great for zero-knowledge and multi-party cryptography
