Deterministic Execution for
Scientific Workflows.
Project Helio is a deterministic execution kernel built in Rust. It solves the reproducibility crisis in stochastic processes by enforcing zero-divergence, instruction-level determinism natively via strict Wasmtime and WASI environment shimming.
Powered By Industry-Leading Technology
Built for Reproducibility and Security
High-assurance computing isolation to verify and cryptographically sign execution payloads without divergence.
Instruction-Level Determinism
Safely overrides and stubs environmental non-determinism (like getrandom or clock_gettime) from guest Wasm payloads.
Capability-based Security
Enforces safe multi-tenant capability-based isolation directly down to hardware limits (i.e., strict memory allocation).
Cryptographic Provenance
Uses a heavily robust Merkle-DAG state engine to map out payload programmatic graphs locally to trace all inputs, contexts, and outputs using Canonical JSON (RFC 8785) and SHA-256.
Signature Authentication
Cryptographically signs over all execution output files natively using Ed25519 standard proofs. Verify artifacts instantly.
