Verifiable Provenance of Software Artifacts with Zero-Knowledge Compilation

Paper

https://arxiv.org/abs/2602.11887

Javier Ron zkVM RISC Zero

Javier Ron and Martin Monperrus propose a zkVM-based approach for software provenance verification in their paper, generating compiled outputs and proofs to ensure secure and verifiable compilation.

Notes

Traditional reproducible builds require matching toolchains and environments, making implementation difficult.
zkVM compilation executes compilers within zkVMs to produce outputs and cryptographic proofs.
Proofs verify compilation was performed on claimed source code with claimed compiler.
Proof-of-concept implemented using RISC Zero zkVM and ChibiCC C compiler.
Evaluated on 200 synthetic programs and real-world software like OpenSSL and libsodium.
Successfully blocks adversarial tests including compiler substitution, source tampering, output manipulation, and replay attacks.

Why are reproducible builds insufficient to fully solve provenance?

Reproducible builds require re-executing the build in an identical toolchain and environment. Achieving perfect environment matching is complex and fragile, making verification difficult.

What is the core advantage of running compilation inside a zkVM?

A zkVM generates a cryptographic proof alongside compilation, attesting that the output was produced from the specified source and compiler. Verifiers can validate the execution without re-running the build.

What potential impact does this approach have on software supply chain security?

It enables cryptographically verifiable binaries, potentially transforming open-source distribution and package management by allowing users to verify artifact provenance without trusting the builder.
