NDID Simplified with a Scenario

This section gives you a quick overview of the digital identity platform, illustrated through a simple scenario.

Let's consider a use case where you're applying for a Visa at an embassy. They need your identity and bank statement. Without a digital identity platform, this would require a lot of paperwork.

With a digital identity platform, this process is much simpler. First, we define these participants:

• User, in this example, the applicant.
• Relying Party (RP) relies on the NDID platform to provide service to users. In this example, the embassy.
• Identity Provider (IdP) holds the identity of the user, and is able to prove the identity the user.
• Authoritative Source (AS) holds the user’s information, such as bank statement. In this example, the bank.
• The NDID platform
  • A decentralized app with nodes running on each RP, IdP, and AS, connecting them together.
  • Exposing an HTTP-based API to enable integration with each party.
  • Transaction logs (without ID or private information, but contains zero-knowledge proof to verify the transaction) are recorded on the blockchain (Tendermint).
  • Private information (ID information, data from AS) is communicated between nodes securely through ZMQ.(https://zeromq.org/)

Some parts of data related to each identity is stored privately by each participating party, while others are on the blockchain.
