It discusses how blockchain could address issues with existing crowdfunding platforms like high fees and scams by providing a decentralized, transparent, and secure system. Blockchain allows every transaction to be recorded in a distributed ledger and uses smart contracts to automate funding. The document reviews several research papers analyzing the benefits of blockchain crowdfunding systems like ICOs and IEOs over traditional models as well as potential challenges around performance, lack of standards, and unrecoverable bugs. It proposes a decentralized crowdfunding application on the Ethereum blockchain to provide investor protection without a centralized intermediary.
