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. Every action builds a verifiable track record. The accountability primitive for AI agents.

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.

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

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.

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

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

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.

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

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

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.
