On February 11, the BBC's official website published an article entitled "Blockchain: A Revolution That Hasn't Fully Happened". It is mentioned in the article that blockchain technology has existed for more than ten years, and some large enterprises have incorporated blockchain technology into their operations, and the impact of blockchain will certainly continue. Shipping giant Maersk uses blockchain technology in TradeLens, which can be used to track customs documents for international shipments. Professor Gilbert Fridgen, an expert on financial services at the University of Luxembourg, recommends a distributed ledger system that tracks the certificates and degrees awarded by the university. Proponents believe that it may be a better alternative to traditional databases.
