Recently, Gartner released the 2019 blockchain technology technology maturity curve (Hype Cycle for Blockchain Technologies) shows that the blockchain has entered the bubble burst period. With the advancement of technology and the continued popularity of the blockchain's unique practical applications, the market will be out of this stage in 2021. Avivah Litan, Gartner Distinguished Analyst and Research Vice President, said: "The blockchain technology has not yet reached a mature stage. Most of the blockchain projects of enterprises are still in the experimental mode. The blockchain is still unable to realize the digital business of each business ecosystem. Change, and this can't be done at least until 2028. Gartner predicts that by 2028, blockchain technology and operations will be fully expanded."
