The head of the digital finance department of China Everbright Bank said: "The application of 5G, Internet of Things and blockchain technology is particularly important for the banking industry, especially to build a strong, reliable and socially trusted technology platform. Blockchain technology relies on it. The characteristics of centralization, transparency and non-tampering can better solve the problem of credit.” Everbright Bank said that it will actively use the blockchain technology to participate in social welfare undertakings. The “decentralization”, anonymity, and non-destructive modification of blockchain can effectively enhance the credibility of public welfare undertakings while ensuring the security of user information, and make public welfare donations traceable in real time. At present, China Everbright Bank has completed the POC test of the “Mother Water Margin” charity donation project based on the blockchain.
