Zheng Lei, director of the Digital Economic Research Center of the Hong Kong International New Economic Research Institute, said that blockchain technology can open up the front-end, middle-end and back-end data, and make the donation data and distribution data public. There is a time for donation or allocation, allocation and use Stamp records, and each fund can be quickly matched for verification. The blockchain uses a distributed technology and consensus algorithm to reconstruct a trust mechanism. The data stored on the chain is reliable and cannot be tampered with.

The data on the blockchain not only technically protects the authenticity of public welfare data, but also helps public welfare projects save information disclosure costs, which fully reflects the value of blockchain public welfare.
