Hyperledger Indy is an open-source blockchain framework built for decentralized identity management. It provides tools, libraries, and protocols for creating and managing self-sovereign identities.
What is self-sovereign identity?
Self-sovereign identity refers to the concept of individuals having full control and ownership over their personal identity information. It allows individuals to securely manage and share their identity attributes without relying on centralized authorities.
What are the key features of Hyperledger Indy?
The key features of Hyperledger Indy include:
- Decentralized identity management.
- Privacy and security of personal data.
- Selective disclosure of identity attributes.
- Verifiable credentials.
- Interoperability with other identity systems.
How does Hyperledger Indy address privacy concerns in identity management?
Hyperledger Indy uses zero-knowledge proofs to allow individuals to prove certain facts about themselves without revealing unnecessary personal information. This ensures privacy and minimizes the disclosure of sensitive data.
What are verifiable credentials in Hyperledger Indy?
Verifiable credentials in Hyperledger Indy are digital representations of identity information that are cryptographically signed by issuers. They allow individuals to prove their identity attributes without revealing the underlying data.
How does Hyperledger Indy handle identity revocation?
Hyperledger Indy employs a revocation mechanism based on cryptographic accumulators. Revocation is done by adding revoked credentials to the accumulator, and verifiers can check if a credential has been revoked without accessing a revocation authority.
What is the role of a steward in Hyperledger Indy?
Stewards are trusted entities in the Hyperledger Indy network. They have the ability to write schema and credential definitions to the ledger, ensuring the integrity of the identity ecosystem.
How does Hyperledger Indy ensure interoperability with other identity systems?
Hyperledger Indy adopts a set of open standards, including the W3C Verifiable Credentials and DID specifications. These standards enable interoperability and seamless integration with other identity systems.
What is a decentralized identifier (DID)?
A decentralized identifier (DID) is a unique identifier for an entity in the Hyperledger Indy network. DIDs provide a way to reference and interact with entities without relying on a centralized authority.
How does Hyperledger Indy handle scalability?
Hyperledger Indy can achieve scalability through the use of decentralized networks and the distribution of identity-related operations across multiple nodes. It allows for the growth of the network while maintaining performance and reliability.
