Simplifies comparing photos of tamper-evident seals and patterns using your eyes

Scalable and practical Byzantine fault detection middleware for transactional database systems

The scalable, auditable and high-performance tamper-evident log project

Self-hosted tamper-evident evidence database for files, audit events, and data handoffs with portable offline verification

Laravel audit log & change history with real actor attribution (user / job / command / scheduler), cross-model change traces, time machine, tamper-evident hash chain, GDPR reports, anomaly detection, Slack/webhook alerts, multi-tenancy and an optional dashboard.

Tamper-evident runtime evidence for AI agents: hash-chained Runtime Records, dependency-free, verifiable by anyone.

Tamper-evident evidence and verification layer for AI agents. Verify any agent's session offline with just openssl. No cloud, no lock-in.

Tamper-evident evidence infrastructure for AI agents. Capture, seal, verify, and audit AI decisions in a single portable .epi file.

Open-source governance infrastructure for AI-assisted legal work

A police department for your Claude Code agents — a logging-only hook + CLI that audits the main agent and every subagent and reports rule offenses (permission bypass, out-of-scope & credential access, self-permissioning, disallowed tools, redundant, off-task) with quoted evidence. Catch-and-report, never blocks.

Deterministic authorization + tamper-evident audit for AI agents, humans, and workloads — one principal type, safety invariants machine-checked by an SMT solver (cvc5), every decision independently verifiable offline. Pure Rust.

The open protocol for cryptographically sealed audit records of autonomous AI operations. SHA3-256 + Ed25519 + hash chain. Spec, conformance suite, and reference implementations in Python and TypeScript.

ARI — Artificial Reasoning Intelligence. Personal AI operating system with 7-layer architecture, three-pillar cognition (LOGOS/ETHOS/PATHOS), constitutional governance, and tamper-evident SHA-256 audit trails. Local-first. Multi-agent. TypeScript.

Rootsign is an open-source tamper-evident decision and action provenance logging library for AI agents

Open protocol for signed, verifiable machine decisions. Ed25519 receipts, hash-chained audit trails, in-toto predicate type. 3 IETF Internet-Drafts. Apache-2.0.

Tamper-evident cryptographic receipts for AI outputs - offline-verifiable (SHA-256 + Ed25519). Supports EU AI Act Article 12 record-keeping. Prototype of Signet.

Give any data cryptographic proof of integrity. Records → Merkle trees → anchored on Hyperledger Fabric. REST API, Go & Python SDKs.
