Components

The NDID platform node mainly consists of 3 components:

• Distributed Ledger Technology (DLT)

  A system for replicate, share, and synchronize public data across multiple nodes in the network. A type of DLT used is blockchain. Tendermint has been chosen as a blockchain layer of the platform since it can support required throughput. The logic that utilizes blockchain or smart contract or as Tendermint calls it ABCI app is implemented in Go.

  Repository: smart-contract

• API

  A set of programmable interface for external applications to utilize the platform. It is also the part that coordinates between other components. The implementation is in JavaScript (Node.js).

  Repository: api (main-server)

• P2P Communication Channel

  Peer-to-peer communication channel for private data exchange between platform nodes. The technology used is ZeroMQ.
