Openclaw Ledger

Tamper-evident audit trail for agent sessions. Hash-chained logs of workspace changes with cryptographic verification. Know exactly what changed, when, and detect if anyone altered the record. Free alert layer — upgrade to openclaw-ledger-pro for freeze, forensics, and chain restoration.

Tamper-evident audit trail for agent workspaces. Every workspace change is recorded in a hash-chained log — if anyone alters an entry, the chain breaks and you know.

The Problem

Agents modify files, execute commands, install skills — and leave no verifiable record. If something goes wrong, you can't trace what happened. If logs exist, nothing proves they haven't been altered after the fact.

Commands

Initialize

Create the ledger and snapshot current workspace state.

python3 {baseDir}/scripts/ledger.py init --workspace /path/to/workspace

Record Changes

Snapshot current state and log all changes since last record.

python3 {baseDir}/scripts/ledger.py record --workspace /path/to/workspace
python3 {baseDir}/scripts/ledger.py record -m "Installed new skill" --workspace /path/to/workspace

Verify Chain

Verify the hash chain is intact — no entries tampered with.

python3 {baseDir}/scripts/ledger.py verify --workspace /path/to/workspace

View Log

Show recent ledger entries.

python3 {baseDir}/scripts/ledger.py log --workspace /path/to/workspace
python3 {baseDir}/scripts/ledger.py log -n 20 --workspace /path/to/workspace

Quick Status

python3 {baseDir}/scripts/ledger.py status --workspace /path/to/workspace

How It Works

Each entry contains:

• Timestamp
• SHA-256 hash of the previous entry
• Event type and data (file changes, snapshots)

If any entry is modified, inserted, or deleted, the hash chain breaks and verify detects it.

Exit Codes

• 0 — Clean / chain intact
• 1 — No ledger or minor issues
• 2 — Chain tampered / corrupt entries

No External Dependencies

Python standard library only. No pip install. No network calls. Everything runs locally.

Cross-Platform

Works with OpenClaw, Claude Code, Cursor, and any tool using the Agent Skills specification.
