On October 31, Hebei News Network published an article "The blockchain is not just "bitcoin"." The article pointed out that in the past few years, the blockchain industry has been sought after from everyone to slow down, which is not unrelated to the following phenomena. First, the chain currency does not separate. Earlier, due to the demonstration effect of Bitcoin, the latecomers of the blockchain said that they must be called coins. In the public's impression, these two concepts have always been tied together. As the central bank explicitly banned the ICO (the first token issue), the blockchain currency disappeared completely in the country, and this also affected the pool fish. The blockchain was once considered "not reliable" by the outside world. Second, the hard blockchain chain. With the blockbuster heat, there have been many companies that clearly do not need blockchain technology, but have claimed to apply blockchain technology. Such products and applications are not only meaningless, but also greatly seize the resources of real blockchain enterprises. Third, the public chain syndrome. Early blockchain developers, one mind to do the public chain. The development of public chain investment is high and the effect is slow. This is why the outside world feels that many blockchain companies have not made any breakthroughs in development for many years. It can be said that the existence of the above phenomenon has caused some people to have some ambiguity about the development direction of the blockchain industry. Fortunately, the direction is now clear – to play the role of blockchain in promoting data sharing, optimizing business processes, reducing operational costs, improving synergy efficiency, and building credible systems.
