About Stoffel
Stoffel is a secure multi-party computation toolchain for developers, maintained by Stoffel Labs, which separates MPC programs from the cryptography underneath. Applications are written in StoffelLang, compiled to .stflb bytecode and executed by a register-based Stoffel VM across parties, with QUIC on the network layer. Building MPC by hand means handling secret sharing, preprocessing triples and Byzantine fault tolerance, and teams often fall back to a single key holder; Stoffel ships two asynchronous backends, HoneyBadgerMPC for field arithmetic and AVSS for committed scalar shares, with a topology requiring at least 4t+1 parties, and a local test network launched through stoffel run, with a Solidity SDK handling on-chain input collection and output distribution, and project settings held in Stoffel.toml covering backend, parties and threshold.
The toolchain supports BLS12-381, BN254, Curve25519, Ed25519, secp256k1 and P-256, and covers distributed key generation, threshold signing and a Solidity SDK for on-chain coordination. Version 0.1.1 shipped on 6 July 2026 with the full crate set and the stoffel-run runner; the mpc-protocols component was audited by Zellic, and an outside developer used the stack for a genomics aggregate study with 100 participating clients.
As a Web3 data analyst, here are Stoffel's key developments from 2026-03-01 to 2026-09-01:
Core Release & Technical Progress Stoffel officially launched v0.1.0 (2026-06-22), its full MPC runtime stack. The follow-up v0.1.1 (2026-07-06) focused on developer experience: bundling stoffel-run with the CLI, enabling Rust SDK to locate the runner via PATH, and strengthening compiler support for AES/CTR/CBC-style MPC programs. Runtime fixes included per-compile optimizer budgets, safe flattening of nested Share.batch_mul operands, AVSS preprocessing improvements, and preserving client-store counts across VM clones.
Roadmap & Future Focus Official priorities include: (1) completing MPC protocol integration with full preprocessing and computation coordination, (2) building distributed deployment helpers for multi-machine MPC, and (3) adding protocols beyond HoneyBadger. A coordinator service for preprocessing orchestration (Linear STO-245) and direct client input access in programs are pending items.
Ecosystem Signal An independent developer built a private genomic study prototype on Stoffel, indicating early external adoption beyond the core team.
Mikerah Quintyne-Collins — Founder & CEO; raised a $1.6M pre-seed in 2025 and shipped the production-grade MPC runtime Stoffel 0.1.0.
