Overview

The Cloud Agent is a scaleable, easy-to-use, robust, and W3C standards-based agent that provides self-sovereign identity (SSI) services to build products and solutions based on it. The Cloud Agent exposes REST API for integration with any programming language.

The Cloud Agent provides all the required capabilities to leverage the power of decentralized identity through the support of W3C standards, DIDComm, and the Hyperledger Aries protocols, solutions based on the Cloud Agent are interoperable with the SSI ecosystem. The Cloud Agent includes the following high-level features:

  • Use the Cloud Agent API to develop controllers that implement specific business logic according to use case requirements.
  • Develop controllers in any programming language and remove the requirement for developers to interact or learn the nuts and bolts of the various standards.
  • The Cloud Agent is written in Scala, supports the did:prism method, interacts with the PRISM Node over gRPC protocol, and uses it as the Verifiable Data Registry.
  • The PRISM Node interacts with a distributed ledger, providing high security, scalability, and availability.
  • The Cloud Agent is a cloud agent accessible from anywhere.
  • Highly scalable and flexible, making it well-suited for a wide range of use cases and applications.
