Apps say that only people in first-tier cities know about this technology, but it is not widely understood, let alone other first-tier cities. Banks are also preparing to apply blockchain technology but have not really applied it. The financial industry also needs to apply it, but it is not known when. To be precise, blockchain is only in the initial trial stage in China.
The current industry in China where blockchain has been applied is network mutual aid. As far as I know, the network mutual aid platform Tongxinhuzhu is the first real blockchain application in China. Through blockchain and Big data technology eliminates the shortcomings of the traditional network mutual aid model and establishes an open and transparent new network mutual aid platform.
You can download their blockchain client to experience it.
