NFTs can serve as transparent on-chain funding vouchers for公益 projects. By minting NFTs to represent donations or funding contributions, projects can leverage blockchain's immutability to publicly record transactions. Each NFT can embed details like donor info, amount, and purpose, ensuring traceability. Smart contracts can automate fund allocation, enhancing accountability. Donors receive NFTs as proof of contribution, fostering trust and engagement. Public ledgers allow stakeholders to verify fund usage, reducing mismanagement risks. However, high minting costs and energy concerns may limit scalability, requiring eco-friendly blockchains. Overall, NFTs offer a novel, transparent solution for公益 funding.
