This article will comprehensively analyze the mysteries of digital currency for you from the aspects of definition, classification, technical principles and recent hot topics.
1. Definition of digital currency
Digital currency is a virtual currency based on cryptography technology. It does not rely on physical forms, but exists in electronic form. The core features of digital currencies are decentralization, anonymity and security. Unlike traditional currencies, the issuance and transaction of digital currencies does not rely on central banks or financial institutions, but is implemented through distributed ledger technology (such as blockchain).

| Central Bank Digital Currency (CBDC) | Issued by the central bank, a digital form of legal currency | Digital RMB (e-CNY), digital euro |
3. Technical principles of digital currency
The core technology of digital currency is blockchain, which is a distributed ledger technology. Blockchain records transaction data through a decentralized node network to ensure that the data is tampered with, transparent and traceable. The following are the key features of blockchain:
| Features | illustrate |
|---|---|
| Decentralization | No central organization control, and is maintained by the entire network nodes. |
| Can't be tampered with | Once written to the blockchain, data cannot be modified or deleted. |
| Transparency | All transaction records are publicly verified, but the user's identity is anonymous |
