AETHERIS Day 8: Groth16 On-Chain Verifier — Component #16/730

Building AETHERIS in Public — Day 8

Phase 4: The ZK Privacy Layer
Hiding strategy from MEV bots while proving validity to the chain. The Ghost Layer.


Component: Groth16 On-Chain Verifier

The Groth16 On-Chain Verifier achieves a significant reduction in gas costs, decreasing from 500k to 200k gas by leveraging optimized BN254 assembly for Groth16 ZK-proof verification. This optimization of BN254 pairing checks results in a 300k gas savings, making zero-knowledge verification more viable for users by reducing costs from prohibitively expensive to manageable.

Why This is Production-Grade

ZK verification costs 500k gas naively. Optimized BN254 pairing checks bring this to 200k — the difference between viable and too expensive for users.

Assembly Optimization

BN254 elliptic curve pairing operations in raw assembly — the most complex Yul possible

The AETHERIS Vision

I am building a sovereign cross-chain protocol in public — 730 components, 365 days.

Every component serves the larger architecture. Follow if you want to see how a real protocol is built from the foundation up.
