Identity

The FHE-powered Decentralised Identity Stack is a sophisticated and privacy-centric identity solution that addresses one of the biggest challenges in decentralised systems: secure, verifiable, and private identity management over the Shib Ecosystem.

Key Features of the FHE-Powered Identity Stack​

  • Fully Homomorphic Encryption (FHE):

    Data Privacy: FHE enables data to be encrypted yet fully functional. This means that user data, such as verifiable credentials, can be checked without ever needing to decrypt it, keeping personal information secure at all times.

  • On-chain Comprehensive Decentralised Identity Stack:

    Unified Digital Identity: With an on-chain Decentralised Identity solution, Shibizens have a single, consistent digital identity across the entire ecosystem. This eliminates redundancy and reduces friction when interacting with different services across the Shib Ecosystem, from governance and financial applications to social platforms. The solution is compliant with W3C’s DID Spec.

  • Verifiable Credentials:

    Secure, Trustworthy Credentials: The identity stack supports credentials verified through FHE, meaning these credentials can be trusted without compromising user privacy. Verifiable credentials provide Shibizens with proof of identity, reputation, or access rights while remaining secure and private. The solution is compliant with W3C’s Verifiable Credential Spec.

  • Verifiable Credentials Schemas:

    Credential Schemas: The credentials support Data schema that the issuers can choose from while issuing credentials. Schemas support both encrypted and plaintext Identity Claims.

  • Privacy in Verification:

    Privacy across KYC: This feature allows identity verification (e.g., Know Your Customer, or KYC) without exposing sensitive information. This is invaluable for users/organisations/institutions who prioritise privacy and want to retain control over their data or user data within the network state. The KYC process is conducted once, and then users can apply these credentials to various services within the ecosystem, streamlining access and ensuring consistent compliance without requiring repeated identity checks.

  • Interoperability:

    This stack is designed to work seamlessly with various on-chain applications, allowing Shibizens to engage in activities within the network state with a single, verified identity that is trusted across all services.

  • Data Control and Ownership:

    Users retain control over their identity data, which is stored securely on the blockchain, with permissions for sharing with verifiers (merchants, authorities) only when necessary. Only the user have control over their encrypted data. This supports self-sovereign identity principles, a cornerstone of decentralized and Web3-oriented communities.

  • Potential Applications

    • KYC: Privacy-preserving KYC can be performed over blockchain using Shib Identity.
    • Reputation System: DID can be used in Reputation Engines like Karma Points.
    • On-chain Credentials: On-chain credentials can be used across DAOs and NFTs.
    • IoT and Sensor Data: Enables privacy-preserving storage and sharing of data generated by IoT devices while providing an identity to the device under Industry 4.0

  • SDK for Integration:

    The Identity SDK can be used for integrating dapp Frontends to the corresponding DID, VC and Schema Registries Contracts on-chain and to the FHEVM KMS off-chain. Learn how to use this tool on the next page.
