As far as the current state accepts the technology of blockchain, I am very skeptical about the development of the blockchain, so I think no matter which country it is, if the blockchain is really used in the international conference, then the development of the blockchain There is more than one layer of protection.
National governments have different attitudes toward blockchains, but they are absolutely impossible to reject. They are only looking for the right time to introduce them. Blockchain technology has helped many industries and reduced many costs. They will not give up these opportunities.
