From a technical point of view, blockchain is a safe, reliable and decentralized database technology with the characteristics of data being difficult to tamper with, transparent and efficient. It makes the data stored in the distributed network through cryptography and knowledge mechanism, thus improving the security and credibility of the data. At the same time, blockchain technology can automatically execute smart contracts, realize untrusted transactions and cooperation, and reduce transaction costs and risks.
Although blockchain has many advantages and application prospects, there are also some problems and challenges. For example: security issues, privacy protection issues, technology maturity issues and regulatory issues. Therefore, we should actively explore and study the application and development trend of blockchain technology, and at the same time pay attention to preventing and solving related problems and challenges to promote the healthy development of blockchain technology.
