This is an initial project created from scratch to begin learning about how to develop Ethereum smart contracts using Solidity.
| Tool | Description |
|---|---|
| Ganache | Provides a local blockchain to deploy the contract to |
| Microsoft VSCode | Excellent integrated development environment |
| solidity extension | The de-facto solidity plugin for VSCode |
| Truffle Suite | A command-line suite of tools that provide compilation, testing and deploying smart contracts to development and production blockchains |
| Remix Extension | Excellent way to test contract code using VSCode |
| Infura (optional) | For deploying a contract to test networks like ropsten |
| Metamask (optional) | Web browser extension to manage wallets |
The design is simple, as the intent of the project is to gain experience deeveloping a solidity app from scratch.
| ID | Step | Description |
|---|---|---|
| 1 | Create participant(s) | Assigns new participants their own internal ID. A participant can be a supplier or a consumer. |
| 2 | Create product(s) | These are the items that will be assigned to participants. A supplier makes a product and a consumer then purchases/owns a product. |
| 3 | Assign ownership | Once participants and products are created they can be assigned |
There are also test created in the tests.js file, which I would run to validate functionality and identify problems.
Once set up, the following are the steps I took to test changes. Using the VS code terminal:
truffle test
This compiles the code then deploys it to Ganache, the tests the contract methods.
This project will be updated over time to improve how a supply chain is emulated, working towards a more real world and practical application.
