Today is my last day at @taikoxyz as zkEng lead / Head of proof systems / Chief Scientist.

Between optimizing our own zkEVM, pivoting to zkVMs, adding ZK and SGX multi-proofs, the rise of based sequencing and based preconfirmations, it was a wild ride.

Oh and a mainnet baby!

Releasing Constantine v0.1.0, the fastest backend for Ethereum cryptography.
BLS signatures, EVM crypto-precompiles, KZG polynomial commitments for blobs (EIP-4844). All accelerated, with multithreading support. And the fastest MSM for elliptic curves.

Finished implement EIP-2537 (BLS12-381 precompiles) with full benches.
I think we can bring down gas cost by 2.5x to up to 15x compared to current.

Benchmarks done with laptop CPUs from 9 years ago to today and Raspberry Pi 4.
