Chen Weixing: Only currency and digital assets are sufficient to use a secure database such as blockchain

Fancheng Capital Weiwei Chen said that the blockchain is an encrypted ledger. Through asymmetric encryption, for each transaction, a block composed of several transactions, a chain composed of several blocks following the Merkle tree, and decentralization. Consensus performs cryptographic signatures at four levels to ensure that each piece of data is almost absolutely secure. It's like a house with a 1-kilometer-thick wall, using the most advanced materials and security. Only the most valuable numbers should be stored in such a database that ignores efficiency in the blockchain, just like only the most valuable items are placed in this secure house. So only currency and digital assets are enough to use this kind of secure database.
