Excited about the #beamchain proposal by @drakefjustin! At @lita_xyz we want to make this a reality. We'll test compiling Nim and Rust clients state transition in Valida at first (as we have initial C/Rust support).

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. https://ethresear.ch/t/releasing-constantine-v0-1-0-a-modular-cryptography-stack-for-ethereum/19990

I accelerate Rust code with Nim following ZAL ;), the Zk Accel Layer: https://github.com/mratsim/constantine/pull/308 Compared to Rust frameworks I'm 1.8x to 4.5x faster (Arkworks, Bellman, Halo2, see https://github.com/mratsim/constantine/pull/226 )
