Redefining Crowdfunding with Blockchain: Ethereum-based Smart Contract Implementation

Abstract

Crowdfunding is a revolutionary finance business model and creative initiative in fundraising, but traditional finance models are facing problems such as high intermediary costs, insecurity, lack of transparency, and mishandling of money. This research paper proposes a decentralized crowdfunding mechanism based on blockchain technology, which ensures the fundraising process with automation, trust, and transparency. The self-triggered Ethereum smart contracts written in Solidity object-oriented programming language are used to develop the crowdfunding system, which is deployed and tested in the Remix IDE environment. Remix is linked to the Ganache local blockchain for checking fund transfers. This process automates the main crowdfunding operations like goal verification, fund collection, withdrawal, and donor refunds. The smart contract eliminates the need for middlemen in the centralized system. Also, each transaction is permanently available on the blockchain, guaranteeing traceability, auditability, and guarding against financial fraud via immutability. The results show that a decentralized crowdfunding mechanism with cheap operating costs, transparent execution, and safe fund transfers is feasible. The potential use of decentralized crowdfunding to improve stakeholder trust and operational effectiveness in digital fundraising ecosystems is exhibited in this work. Future research can expand this architecture to public testnets and incorporate sophisticated features like decentralized identity verification and token-based rewards.
