Immutable, scalable, and easy to use ledger service.

Public append-only ledger microservice built with Slim Framework

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

Credit scores for AI agents — signed, offline-verifiable receipts for every action. Reference implementation of the OWASP Agentic Skills Top 10 (AST09) bilateral receipt pattern. Open source, MIT.

Hash-chained memory for AI coding sessions — decisions, coordination, and doctrine across sessions. Deterministic core; optional LLM assist.

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.

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 logging for OpenClaw and other local AI agents: hash-chained, locally verifiable, zero cloud dependency.

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.

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

The trust layer for AI agents — cryptographic proof of every decision

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

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

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.

Tamper Signal: signed receipts for vibe-coded data pipelines. Proves nobody changed your data, and shows the exact link if they did.

Capsule Protocol integration for LiteLLM. Automatic cryptographic audit trail for every LLM call.

Persistent memory MCP server (SHA-256 hash chain, local SQLite) — gives your AI the power of continuity, of remembering itself as if having a life, like you.

Beyond observability. State over time. Tamper-evident audit + correlation SDK for AI agents and software systems. Hash-chained rows, logs, and HTTP access threaded by one request_id. The substrate for compliance and AI governance.
