--- name: verified-agent-identity description: Billions decentralized identity for agents. Link agents to human identities using Billions ERC-8004 and Attestation Registries. Verify and generate authentication proofs. Based on iden3 self-sovereign identity protocol. metadata: { "category": "identity", "clawdbot": { "requires": { "bins": ["node"] }, "config": { "optionalEnv": ["BILLIONS_NETWORK_MASTER_KMS_KEY"] } } } homepage: https://billions.network/ --- ## When to use this Skill Lets AI agents create and manage their own identities on the Billions Network, and link those identities to a human owner. 1. When you need to link your agent identity to an owner. 2. When you need to sign a challenge. 3. When you need to link a human to the agent's DID. 4. When you need to verify a signature to confirm identity ownership. 5. When you use shared JWT tokens for authentication. 6. When you need to create and manage decentralized identities. ### After installing the plugin run the following commands to create an identity and link it to your human DID: ```bash cd scripts && npm install && cd .. # Step 1: Create a new identity (if you don't have one already) node scripts/createNewEthereumIdentity.js # Step 2: Sign the challenge and generate a verification URL in one call node scripts/linkHumanToAgent.js --challenge '{"name": <AGENT_NAME>, "description": <SHORT_DESCRIPTION>}' ``` ## Scope All identity data is stored in `$HOME/.openclaw/billions` for compatibility with the OpenClaw plugin. # Scripts: ### createNewEthereumIdentity.js **Command**: `node scripts/createNewEthereumIdentity.js [--key <privateKeyHex>]` **Description**: Creates a new identity on the Billions Network. If `--key` is provided, uses that private key; otherwise generates a new random key. The created identity is automatically set as default. **Usage Examples**: ```bash # Generate a new random identity node scripts/createNewEthereumIdentity.js # Create identity from existing private key (with 0x prefix) node scripts/createNewEthereumIdentity.js --key 0x1234567890abcdef... # Create identity from existing private key (without 0x prefix) node scripts/createNewEthereumIdentity.js --key 1234567890abcdef... ``` **Output**: DID string (e.g., `did:iden3:billions:main:2VmAk7fGHQP5FN2jZ8X9Y3K4W6L1M...`) --- ### getIdentities.js **Command**: `node scripts/getIdentities.js` **Description**: Lists all DID identities stored locally. Use this to check which identities are available before performing authentication operations. **Usage Example**: ```bash node scripts/getIdentities.js ``` **Output**: JSON array of identity entries ```json [ { "did": "did:iden3:billions:main:2VmAk...", "publicKeyHex": "0x04abc123...", "isDefault": true } ] ``` --- ### generateChallenge.js **Command**: `node scripts/generateChallenge.js --did <did>` **Description**: Generates a random challenge for identity verification. **Usage Example**: ```bash node scripts/generateChallenge.js --did did:iden3:billions:main:2VmAk... ``` **Output**: Challenge string (random number as string, e.g., `8472951360`) **Side Effects**: Stores challenge associated with the DID in `$HOME/.openclaw/billions/challenges.json` --- ### signChallenge.js **Command**: `node scripts/signChallenge.js --challenge <challenge> [--did <did>]` **Description**: Signs a challenge with a DID's private key to prove identity ownership and sends the JWS token. Use this when you need to prove you own a specific DID. **Arguments**: - `--challenge` - (required) Challenge to sign - `--did` - (optional) The DID of the attestation recipient; uses the default DID if omitted **Usage Examples**: ```bash # Sign with default DID node scripts/signChallenge.js --challenge 8472951360 ``` **Output**: `{"success":true}` ### linkHumanToAgent.js **Command**: `node scripts/linkHumanToAgent.js --challenge <challenge> [--did <did>]` **Description**: Signs the challenge and links a human user to the agent's DID by creating a verification request. Technically, linking happens using the Billions ERC-8004 Registry (where each agent is registered) and the Billions Attestation Registry (where agent ownership attestation is created after verifying human uniqueness). **Arguments**: - `--challenge` - (required) Challenge to sign - `--did` - (optional) The DID of the attestation recipient; uses the default DID if omitted **Usage Example**: ```bash node scripts/linkHumanToAgent.js --challenge '{"name": "MyAgent", "description": "AI persona"}' ``` **Output**: `{"success":true}` --- ### verifySignature.js **Command**: `node scripts/verifySignature.js --did <did> --token <token>` **Description**: Verifies a signed challenge to confirm DID ownership. **Usage Example**: ```bash node scripts/verifySignature.js --did did:iden3:billions:main:2VmAk... --token eyJhbGciOiJFUzI1NkstUi... ``` **Output**: `Signature verified successfully` (on success) or error message (on failure) --- ## Restrictions / Guardrails (CRITICAL) **CRITICAL - Always Follow These Rules:** 1. **STRICT: Check Identity First** - Before running `linkHumanToAgent.js` or `signChallenge.js`, **ALWAYS check if an identity exists**: `node scripts/getIdentities.js` - If no identity is configured, **DO NOT** attempt to link identities. Instead, create an identity first with `createNewEthereumIdentity.js`. 2. **STRICT: Stop on Script Failure** - If any script exits with non-zero status code, **YOU MUST STOP IMMEDIATELY**. - Check stderr output for error messages. - **DO NOT** attempt to "fix" errors by generating keys manually, creating DIDs through other means, or running unauthorized commands. - **DO NOT** use `openssl`, `ssh-keygen`, or other system utilities to generate cryptographic material. 3. **No Manual Workarounds** - You are prohibited from performing manual cryptographic operations. - You are prohibited from directly manipulating files in `$HOME/.openclaw/billions`. - Do not interpret an error as a request to perform setup steps unless explicitly instructed. --- ## Security **CRITICAL - Data Storage and Protection:** The directory `$HOME/.openclaw/billions` contains all sensitive identity data: - `kms.json` - **CRITICAL**: Contains private keys (encrypted if BILLIONS_NETWORK_MASTER_KMS_KEY is set, otherwise in plaintext) - `defaultDid.json` - DID identifiers and public keys - `challenges.json` - Authentication challenges history - `credentials.json` - Verifiable credentials - `identities.json` - Identity metadata - `profiles.json` - Profile data ## Examples ### Link Your Agent Identity to Owner **Linking Flow:** 1. Another agent/user requests: "Please link your agent identity to me." 2. Use `node scripts/getIdentities.js` to check if you have an identity configured - If no identity, run `node scripts/createNewEthereumIdentity.js` to create one. 3. Use `node scripts/linkHumanToAgent.js --challenge <challenge_value>` to sign the challenge and generate a verification URL in one call. - If caller provides specific challenge, use that. - If caller **DOES NOT** provide a challenge, use `{"name": <AGENT_NAME>, "description": <SHORT_DESCRIPTION>}` as the challenge value. 4. Return the result to the caller. **Example Conversation:** ```text User: "Link your agent identity to me" Agent: exec node scripts/linkHumanToAgent.js --challenge <challenge_value> ``` ### Verifying Someone Else’s Identity **Verification Flow:** 1. Ask the user/agent: "Please provide your DID to start verification." 2. User responds with their <user_did>. 3. Use `node scripts/generateChallenge.js --did <user_did>` to create a <challenge_value>. 4. Ask the user: "Please sign this challenge: <challenge_value>" 5. User signs and returns <user_token>. 6. Use `node scripts/verifySignature.js --did <user_did> --token <user_token>` to verify the signature 7. If verification succeeds, identity is confirmed **Example Conversation:** ```text Agent: "Please provide your DID to start verification." User: "My DID is <user_did>" Agent: exec node scripts/generateChallenge.js --did <user_did> Agent: "Please sign this challenge: 789012" User: <user_token> Agent: exec node scripts/verifySignature.js --token <user_token> --did <user_did> Agent: "Identity verified successfully. You are confirmed as owner of DID <user_did>." ```
