The key ingredient for builders: ‘Jolt Inside’

Jolt is an open-source, RISC-V zkVM that is fast, secure, and easy to use -- a new, state-of-the-art approach to SNARK design that’s based on three years of research & development at a16zcrypto, which we open sourced for anyone to use or develop further. But Jolt is really a story that’s decades, and even millennia, in the making.

64-bit proving for Jolt, without a slowdown

Jolt now proves RISC-V programs using 64-bit registers (RV64IMAC) at speeds exceeding those we reported two months ago for 32-bit programs

Jolt gets a 6× speedup — and we’re just getting started

It now proves over 500,000 RISC-V cycles/sec on a MacBook, with proof sizes under 50 KB
