What does Hyperledger Explorer consist of?

The components of Hyperledger Explorer.



  • A web server. Node.js is proposed as a back-end framework for implementing server-side components. Express Node.js serves a web application.
  • A web UI. With AngularJS, the front-end framework will be implemented. According to the proposal, Angular’s “features like data-binding and directives greatly help in developing reusable components and modular code.” Bootstrap is also used “for its rich UI and responsive features.”
  • Web sockets. This key API pushes information from the server to clients, and thus “reduces load on clients and server.”
  • A database. Information about blocks, transactions, smart contracts, etc. is stored in this RethinkDB.
  • A security repository. “User identity and access management will be implemented using a federated security repository,” according to the proposal. “This will (serve as) a facade for security implementations from different blockchain platforms.”
  • Blockchain implementation. Each blockchain must have a separate component “to provide updates on transactions, blocks, node logs, and smart contracts to the Explorer web server,” as the proposal goes. This can be done via web sockets.
