WorkBounty: A blockchain based Web3 platform for freelancing ecosystems

The gig economy faces significant challenges with centralized platforms like Upwork and Fiverr, including high service fees (10–20%), opaque algorithms, unreliable reviews, and frequent payment disputes. To address these issues, this work proposes Work Bounty, a decentralized freelancing marketplace powered by Web3 and blockchain technologies. Built on the Ethereum blockchain, the platform utilizes smart contracts to automate critical processes such as job creation, bidding, work delivery, and escrow-based payments, thereby eliminating intermediaries and enhancing trust. Authentication is streamlined using MetaMask wallets, enabling secure, passwordless access tied to unique cryptographic addresses. Job details and deliverables are stored on the InterPlanetary File System (IPFS) to ensure immutable and tamper-resistant data storage, while a blockchain-based reputation system provides transparent, unalterable user ratings. Experimental evaluation on the Ethereum test network demonstrates that the system achieves a 100% success rate in smart contract executions and reduces overall transaction costs to 2–3% equivalent gas fees, compared to the 10–20% fees on centralized platforms. MetaMask authentication achieved a 98.7% success rate, and beta testing with freelancers and clients revealed 92% user satisfaction with the platform&s;s ease of use and trustworthiness. These results highlight the system&s;s potential to provide a secure, transparent, and cost-effective alternative to traditional freelancing platforms, fostering a more equitable and globally accessible gig economy aligned with Web3 principles.
