Crowdfunding has emerged as a powerful mechanism for raising funds for startups, social initiatives, and creative projects. However, traditional crowdfunding platforms are centralized, relying on intermediaries to manage funds and transactions, which often leads to issues such as lack of transparency, high service fees, delayed fund release, and potential fraud. To address these limitations, this paper proposes a decentralized crowdfunding system using blockchain technology. By leveraging smart contracts, the proposed system enables trustless, transparent, and secure fund management without the need for a central authority. All transactions are recorded on an immutable distributed ledger, ensuring accountability and real-time tracking of funds. Smart contracts automatically enforce campaign rules, including funding targets, deadlines, and refund mechanisms, thereby reducing human intervention and operational costs. The decentralized approach enhances security, prevents fund misuse, and builds greater trust between project creators and contributors. This system demonstrates how blockchain can revolutionize crowdfunding by creating a transparent, efficient, and reliable funding ecosystem.
