From digital currency to non-financial field, blockchain technology, as a universal technology, will accelerate the penetration from digital currency to other fields and innovate and integrate. In the future, the application of blockchain will be promoted by two camps: it camp and cryptocurrency camp. The IT camp starts with information sharing, focuses on low-cost credit establishment, and gradually covers digital assets and other fields. Starting from currency, the cryptocurrency camp has gradually promoted to the fields of asset side management and certificate deposit, and spread to credit investigation and general information sharing applications.
