Decentralized Freelancing Platform Using Blockchain Smart Contracts

A decentralised freelancing platform that uses blockchain smart contracts.

A decentralised freelancing platform that uses blockchain smart contracts. It is offered as a reference project: a complete, worked example of how a system like this is designed, built and evaluated, so that a developer can study it, run it and learn from 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.
