4/ On a MacBook, CPU-only Lattice Jolt proves well over 2 million 64-bit RISC-V cycles/sec (curve-based Jolt was ~1 million).
Our new Apple Metal GPU backend takes that to over 10 million — a ~10x jump in a single release, with plenty more to squeeze.

1/ Today we're releasing Lattice Jolt: a post-quantum version of the Jolt zkVM, built on lattices instead of elliptic curves. It's _faster_ than curve-based Jolt and has the shortest proofs of any post-quantum zkVM — under 100 KB.

In March I laid out performance stages for zkVMs. By the end of 2026, we should hit “Stage 2”: 10,000x prover overhead relative to native execution. And that's when things get interesting for applications beyond blockchains.
