Economist Song Qinghui recently issued a statement saying that the blockchain fever in the capital market is on the decline, and funds based on short-term speculation have begun to “sell”. Investors must circumvent blockchain stocks with only conceptual support, away from stocks that rely solely on the concept of speculative currency. In the medium and long term, due to the increasing emphasis on the blockchain industry at the national level, the future of the core technology has the long-term investment value. Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm, etc. It can effectively solve the problem of decentralization and trust between people. The construction and application of blockchain will be able to solve various fields such as agricultural industry development and business environment construction, and make the city a better place. At present, China has a supportive and encouraging attitude towards the blockchain. In particular, it has invested a lot of resources in system construction and technology research and development. In the future, it will inevitably have a positive and wide-ranging impact. The blockchain will become more popular in the future. It is likely to become another "Internet +".
