CampusLedger: Blockchain for Fair Canteen and Shop Operations

CampusLedger, a blockchain system for fair canteen and shop operations on campus.

CampusLedger, a blockchain system for fair canteen and shop operations on campus. This reference project walks through the whole job, from the problem and the design to the build and the evaluation, so that a developer can study how it works, run it and extend it.

It suits learners who want to build decentralised applications: designing smart contracts, testing them, connecting a front end through a wallet and reasoning about security and cost.

The main parts are smart contracts for the core rules, a front end connected through a wallet, tamper-evident records on the chain, and automated contract tests. The reference build uses Solidity, Ethereum, Hardhat, and Web3.js, with a clear project structure, setup instructions and sample data so that it can be run and extended.
