verified-agent-identity

You can create a decentralized agent identity by running the createNewEthereumIdentity.js script, which generates an Ethereum-based DID and stores it locally. This establishes a cryptographically secure identity on the Billions Network for your AI agent.

Linking a human to an agent involves generating verifiable attestations using the ERC-8004 standard. You execute the signChallenge.js and linkHumanToAgent.js scripts to cryptographically bind the human's identity to the agent's decentralized identifier.

Cryptographic proof generation works by having the agent sign a unique challenge string using its KMS-backed keys. The system then validates this signature against the remote DID resolution result to authenticate the agent's identity.

Yes, you need a Node.js runtime environment to execute the identity management scripts. The system also relies on local JSON storage for saving identities and challenges, and requires a KMS-backed key store for secure key management.

Yes, the skill integrates the @0xpolygonid/js-sdk and ethers libraries to handle decentralized identity operations. It also uses @iden3/js-iden3-auth and @iden3/js-iden3-core to validate identities and generate cryptographic proofs on the Billions Network.

Local JSON storage restricts identity and challenge data to a single machine, limiting multi-instance agent deployments. While it supports optional at-rest encryption, it does not provide distributed database redundancy or remote synchronization for decentralized identifiers.
