The difference and connection between blockchain and digital currency

① Difference between the two: Blockchain is an integral project composed of multiple sectors, and digital currency is the largest sector in this project. Blockchain is a technology. Unlike digital currency, it belongs to a virtual currency. Although digital currency is a part of blockchain, some digital currency may not be suitable for blockchain technology.

② Relationship between them: digital currency and blockchain are organically combined, closely linked and have the same technical characteristics. The most successful practice of blockchain is innovation in the currency field, which is the theoretical basis of digital currency. Digital currency needs the support of blockchain technology, which is the most successful application of blockchain technology.

What is the role of blockchain?

Blockchain can reduce the cost of trading activities, the time, money and manpower invested by the unit, and improve efficiency. Improving efficiency means saving, which can save a lot of costs. Blockchain participants are not mandatory. It is conceivable that people can realize their own needs through various forms of blockchain, which means forming a new social operation system.
