Architect a Blockchain Supply Chain Solution - Part B. Udacity Project, April 2019
This DAPP is for a decentralized approach for certifcation schemes, issuance and verification. Any party can become a Certifier and assign a suitable Authority that can delegate authority of certification

| Library | Version | Why used |
|---|---|---|
| Truffle | 5.0.15 | Compile/deploy/test contracts, Ganache for running local test node, Drizzle for React Provider |
| Solidity | 0.5.8 | Compile contracts |
| Node | 10.15.3 | Build React UI |
| Web3 | 1.0.0 (beta 37) | Connect UI to EVM |
| React | 16.8.6 | User interface |
| Transaction ID | Contract address |
|---|---|
| 0xc36f12497b0d7b51f4351303b17b166c83ec71243dbe56e8d8189d83e9f00381 | 0xC4c62eE5bcb488ec2069Ee465f77D7B110328622 |
Here are 3 examples to illustrate how this could work:
| Authority | Certifier | Recipient | Inspector |
|---|---|---|---|
| Specialty Coffee Association | London School Of Coffee | Trainee Barista | Starbucks Manager |
| Driver and Vehicle Licensing Agency | Pymans Garage | Car Owner | Insurance company |
| Oracle Corporation | Oracle Certified Professional | Database Admin | Deutsche Bank HR |
A Certifier would probably have a single Authority per Certificate. Many certificates can be awarded from a scheme and potentially many "Inspectors" could request access to view one or more awarded certificates of a recipient
