bls12-381 is pairing-friendly Barreto-Lynn-Scott elliptic curve construction allowing to:
- Construct zk-SNARKs at the ~120-bit security, as per Barbulescu-Duquesne 2017
- Efficiently verify N aggregate signatures with 1 pairing and N ec additions: the Boneh-Lynn-Shacham signature scheme is orders of magnitude more efficient than Schnorr
BLS can mean 2 different things:
