Notes on commit-reveal schemes, zero-knowledge proofs, and Python cryptography from the commit-reveal maintainers.https://commit-reveal.cryptuon.com/en-ushttps://commit-reveal.cryptuon.com/blog/commit-reveal-vs-vrf-when-each-is-right/https://commit-reveal.cryptuon.com/blog/commit-reveal-vs-vrf-when-each-is-right/Both produce unmanipulable hidden values that get revealed later, but the trust model, interaction pattern, and failure mode are different. A short guide for protocol engineers picking between them.Tue, 12 May 2026 00:00:00 GMThttps://commit-reveal.cryptuon.com/blog/zero-dependencies-as-a-security-property/https://commit-reveal.cryptuon.com/blog/zero-dependencies-as-a-security-property/Supply chain attacks are now the dominant compromise vector for Python packages. A library whose pyproject.toml lists only the language version itself is structurally immune to a class of attacks that depend on installing something. Here is the longer argument.Mon, 04 May 2026 00:00:00 GMThttps://commit-reveal.cryptuon.com/blog/sealed-bid-auction-walkthrough/https://commit-reveal.cryptuon.com/blog/sealed-bid-auction-walkthrough/A worked example: the two-phase auction pattern with this library, using commitments to bind bids, optional Schnorr ZKPs to prove bidder identity, and explicit handling of bidders who refuse to reveal.
