- Oct 19, 2026 Hash Trees and the Root of Trust in a Checksummed Filesystem Why per-block checksums need a chain to a single trusted value, how Merkle trees make tampering localisable, and what the root itself has to be protected against. filesystems
- Mar 30, 2026 Domain Separation in Merkle Tree Hashing How a leaf node and an internal node can hash to the same value, why the standard repair costs one bit of digest, and which schemes still get the distinction wrong. cryptography
- Dec 21, 2025 Merkle Trees as a Signature Scheme: One Key, Many One-Time Keys A hash-based signature is a one-time object, and a binary authentication tree is what turns a finite collection of them into a long-lived public key with logarithmic signatures. cryptography
- Jul 24, 2025 Merkle Trees, Range Digests, and Finding Divergence Without Reading Everything How a tree of hashes narrows a comparison between two replicas to the differing leaves, what it costs to maintain under writes, and why the leaves must align. filesystems
- Jan 24, 2023 Keyless Signing and Transparency Logs for Build Artifacts Short-lived certificates bound to an OIDC identity remove long-lived keys from the signing path, and an append-only log makes a signature public evidence rather than a private promise. security
- Feb 9, 2022 Content-Addressed Artifact Identity and the Cost of Mutable Tags Why a digest derived from bytes is the only stable name for a build output, how Merkle chunking makes large artifacts hashable, and what a mutable tag hides between resolution and pull. devops
