In the morning of December 6th, in the SheKnows community live broadcast on the theme of “Getting out of the truth, where is the application of the public chain?” IOST co-founder Terry said that the current blockchain technology is far from mature, leaving applications There is still distance from landing. In addition, the industry is very eager for quick success and profit, and generally expects too high a blockchain. In 1965, MIT gave birth to the earliest form of email on the CTSS operating system. By 1990, 1% of the world's population had only used email. The blockchain is still too early, and everything has not started yet. The public chain wants to break through and needs to make products on the public chain that really popularize C-side / B-side users and are used extensively. He also pointed out that as a disruptive technology, the application scenarios of blockchain involve all aspects, each field is important and worth exploring. The alliance chain is still a public chain or a private chain. As a technology, it is not necessary to talk about good or bad.
