GUIDE TO ELLIPTIC CURVE PAIRINGS

Summary from the TLDR Crypto newsletter

Elliptic curve bilinear pairings allow for advanced cryptography by mapping points from two elliptic curves to a scalar value while preserving specific mathematical properties. This article explains how the pairings are constructed, with a particular focus on the curves using interesting optimization techniques, like BLS12-381 and BN254. While traditionally considered complex “moon math,” the outcome is efficient signature aggregation, multi-party key exchanges, and zk-SNARK polynomial commitments.
