Abstract

Crowdfunding allows individuals and organizations to collect resources for specific goals, but traditional third-party platforms suffer from issues such as a lack of transparency, high management fees, and low efficiency. Meanwhile, the blockchain can make the circulation of assets transparent and allows users to cooperate without a centralized organization, and smart contracts can provide a collaborative environment that users can trust. This paper suggests that Decentralized Application, enabled by blockchain technology and smart contracts, can be a potential solution for building a better crowdfunding platform. This paper aims to build a blockchain-based decentralized crowdfunding platform, providing more control to investors and easier fundraising for fundraisers. A decentralized application (D-App) is proposed to build this platform, which consists of two layers: a blockchain layer and a frontend layer. The blockchain layer is developed using Web3 technologies that allow integration of traditional web applications to utilize the potential of the blockchain technology. The frontend layer is a React web page based on Web3.js. The frontend can interact with the blockchain layer and provide a unique identity with the use of a wallet provider such as MetaMask and display campaign information to users. Web3 is the next generation of the internet built on blockchain technology, which aims to establish a decentralized ecosystem that allows users to transact, collaborate, and communicate without the need for centralized institutions or platforms.
