Keyhole Fabric API Gateway
This tool is used to provide access to Hyperledger Fabric (HLF) blockchain networks and its data via an API gateway implementation.
APIs are defined query channel configuration information and execute chaincode. The gateway is implemented with Node.js and uses the Express framework to provide RESTful HTTP-based endpoints that access HLF network peers.
Useful for executing Chaincode and Smart Contracts.
Useful for querying the blockchain by client applications.
Authentication logic and validation can be performed here.
Implements a web socket to listen for new blocks being added to the blockchain.
