hash-chain

Immutable, scalable, and easy to use ledger service.

Public append-only ledger microservice built with Slim Framework

Audit AI agent tool-call transcripts: hash-chain sealing, deterministic replay, and scope overreach checks. Dependency-free Python CLI.

Chronicle - Verifiable Audit Logging and Append-Only Audit Trails for Laravel.

Prior direction, kept rather than deleted. Signed, offline-verifiable receipts for AI agent actions, and a reference implementation of the OWASP Agentic Skills Top 10 AST09 receipt pattern. Nobulex is now the independent reliability registry for agent tools: github.com/arian-gogani/nobulex-registry

Local, tamper-evident ledger for coding agents — decisions that survive sessions, coordination that survives agents. Works with Claude Code, Cursor, Codex, OpenClaw, and any MCP client.

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.

AI compliance platform that uses RAG to automatically match AI systems to state regulations, generate grounded disclosure documents, and maintain a cryptographically-signed tamper-evident audit trail.

Privacy-first browser attestation framework for anti-bot and anti-AI scraping. Stateless, cryptographic, and Unix-native. Uses Ed25519 heartbeat chains, WASM attestation, and behavioral continuity validation without tracking users, storing IPs, or collecting telemetry.

Tamper-evident audit log for Go: an append-only, hash-chained, optionally Ed25519-signed log/slog handler, with offline logx verify. Built on the standard library, zero third-party dependencies. Also a full slog toolkit (colored output, JSON, rotation, fan-out, CLI).

Tamper-evident audit trail for Linux process execution. eBPF captures execve, events are SHA-256 hash-chained, shipped to a separate collector, and independently verifiable by anyone holding the file. Educational proof of concept — detection, not prevention.

Cryptographically verifiable audit trail for AI systems — Ed25519 signed, hash-chained Decision Receipts with ISO 42001 / NIST AI RMF compliance. No blockchain, no SaaS.

Inviolate FileMaker logs that live outside the file they audit. Append-only, hash-chained, with a daily AI scan that learns your normal and flags what is not.

Learn COBOL through a live banking system — 18 programs, 6-node settlement network, real-time simulation, Python read/write bridge, SHA-256 tamper detection, AI tutor (Ollama + Claude), static analysis with orthogonal call graphs, and a glass morphism web console. 800 tests.

Local-first governance framework for AI agents. Tamper-evident audit logs, pre-execution gatekeeping, kill switches. No tokens.

AIE Audit-Chain: Ed25519 + O(log n) Merkle audit-trail for KMU consulting (EU AI Act Art. 12). Part of the AIE audit-stack.

RIO Receipt Protocol — Cryptographic proof for AI actions. Open standard for tamper-evident receipts, hash-chained ledgers, and independent verification.

Independent, dependency-free verifier for shim audit evidence bundles

Off-chain append-only, hash-chained, tamper-evident audit layer for AI agents

Capture, preserve, and organize web evidence with cryptographic integrity
