Hal Finney's explanation of secp256k1 "efficiently computable endomorphism" parameters used secp256k1 libraries, archived from source.

The same optimization could be applied to any Koblitz curve (e.g. Short Weistrass curve with a=0).

---

I implemented an optimized ECDSA verify for the secp256k1 curve, based on pages 125-129 of the Guide to Elliptic Curve Cryptography, by Hankerson, Menezes and Vanstone. I own the book but I also found a PDF on a Russian site which is more convenient.

secp256k1 uses the following prime for its x and y coordinates:

BLS Signature for Busy People

Summary

• BLS stands for

  • Barreto-Lynn-Scott: BLS12, a Pairing Friendly Elliptic Curve.
  • Boneh-Lynn-Shacham: A Signature Scheme.

• Signature Aggregation

• It is possible to verify n aggregate signatures on the same message with just 2 pairings instead of n+1.
