BLS12-381: Simplex at playground!
BLS12-381: One Curve for Consensus and Privacy ⚠️ Disclaimer: I’m learning math behind modern validator engines. Math shared here has been copied from the respective sources, and it takes an Eon to truly grok it. BLS12-381 is a pairing-friendly elliptic curve. It appears in Eth2 validator signatures, Filecoin storage proofs, Zcash shielded transactions, and - closer to the subject of this essay - in Commonware’s cryptographic toolkit for BFT consensus. The same algebraic structure that makes BLS threshold signatures possible also underpins several families of zero-knowledge proofs. ...
