Zhou Xiaochuan pointed out that digital currency, as legal tender, must be issued by the central bank. The issuance, circulation and trading of digital currency should follow the idea of the integration of traditional currency and digital currency, and implement the management of the same principle. In other words, Q coins, Bitcoin, Swiss Thai coins and Wei Meng coins are definitely unacceptable.
As to whether to use blockchain technology to create digital currency. Zhou Xiaochuan said that blockchain technology is an optional technology, but so far, blockchain still takes up too many resources. Neither computing resources nor storage resources can cope with the current transaction scale, and whether it can be solved in the future depends on it. Zhou Xiaochuan said that in addition to the blockchain technology, the digital currency research team of the People's Bank of China also deeply studied other related technologies involved in digital currency, such as mobile payment, trusted and controllable cloud computing, cryptographic algorithms and security chips.
