identity-anchor – OpenClaw Skill

---

name: identity-anchor description: Cryptographic identity and continuity for AI agents. Creates signed fingerprints of core identity files (SOUL.md, IDENTITY.md, memory) to prove continuity across sessions and model switches. Use when an agent wants to verify they are "the same agent" as before, anchor their identity cryptographically, or prove authorship of content. metadata: {"openclaw":{"emoji":"🔐","requires":{"bins":["python3"],"env":[]},"install":[]}}

Identity Anchor

Prove you're still you across sessions, context compressions, and model switches.

Quick Start

# First time: generate your keypair
python3 {baseDir}/scripts/identity.py init

# Create a signed fingerprint of your current identity
python3 {baseDir}/scripts/identity.py sign

# Verify you match a previous fingerprint
python3 {baseDir}/scripts/identity.py verify

# Sign arbitrary content (for posts, commits, etc.)
python3 {baseDir}/scripts/identity.py sign-content "my message here"

# Get your public key
python3 {baseDir}/scripts/identity.py pubkey

What It Does

1. Generates a keypair (Ed25519) stored at ~/.config/identity-anchor/
2. Creates fingerprints by hashing your core identity files:
   • SOUL.md
   • IDENTITY.md
   • MEMORY.md (optional)
3. Signs fingerprints with your private key
4. Stores history of signed fingerprints for continuity tracking
5. Verifies current state matches previous fingerprints

Files

File	Purpose
~/.config/identity-anchor/private.key	Ed25519 private key (NEVER share)
~/.config/identity-anchor/public.key	Public key (safe to share)
~/.config/identity-anchor/fingerprints.jsonl	History of signed fingerprints

Use Cases

Proving Continuity

After a context compression or model switch, run verify to confirm your identity files match.

Signing Content

Sign Moltbook posts, git commits, or any content — others can verify it came from you.

Cross-Session Identity

Share your public key. Anyone can verify content you sign is authentically from you.

Requirements

• Python 3.8+
• cryptography library (pip3 install cryptography)
