What it is

A zkVM built on a lookup-centric, sumcheck-based design over multilinear commitments rather than FRI over AIRs, with memory-checking arguments enabling a streaming prover intended to prove arbitrarily long executions in bounded memory without recursion. In September 2026 the maintainers announced a lattice-based variant that replaces the elliptic-curve commitment, claiming post-quantum security and a faster prover.

Strengths and tradeoffs

Strengths
  • Architecturally distinct from the FRI/AIR mainstream, giving the ecosystem genuine proof-system diversity
  • The streaming, low-memory prover profile it targets is a qualitatively different design point
  • Transparent — no trusted setup
Tradeoffs
  • The project states plainly that it is in alpha and not suitable for production, with an explicit not-audited disclaimer — take this at face value
  • Critical findings have already been disclosed and fixed, including a verifier soundness bug
  • Small ecosystem and correspondingly thin auditor coverage
