Blocktrace, a decentralized identity management system

Files

• /hyperledger contains the Hyperledger blockchain logic, smart contracts and authentication cards
• /KYCBackendServer contains the backend server, which interfaces with the blockchain and handles cryptography
• /kyc-admin-app contains the application used by the service to obtain and verify new customer requests

Installation and Development

• Always develop on Composer Playground (in the demo, at http://173.193.98:31080). When done, export as .bna
• Extract the .bna: Using 7z or equivalent, run 7z e -o./hyperledger devtest.bna or equivalent.
• Extract the contents of blocktrace/hyperledger with the extracted .bna, and re-run generate_jsdoc.bat.
• Finally, git add/commit/push.

Description

• Development repository for Blocktrace, a Hyperledger Fabric blockchain back-end supporting remote and decentralized identity verification for businesses to securely onboard customers with no hassle
• Deployed on IBM Cloud using Kubernetes
• REST server and RESTful API at https://173.193.102.98:31090/explorer

About

Blocktrace Hyperledger Model

• User Participants, an abstraction of real-world identity holders (people), contain encrypted UserData objects, which can be modified or accessed through the RESTful API or the smart contract API. The API is only accessible by a back-end server with the correct authentication token, or the requesting business that has been given authorization by the holder of the identity.

Smart Contract Documentation

• The smart contract API provides functionality not provided through the RESTful API. This includes actions that modify the blockchain registries.
• Ensure jsdoc is installed. If not, npm install -g jsdoc.
• Run generate_jsdoc.bat to generate the HTML documentation.
