Pan Weicheng Chen Weixing issued a microblog that the current currency circle, opaque and unregulated, is basically a layer of liar. Too many entrepreneurs who are responsible and responsible. Blockchain is a transparent, programmable, non-tamperable database designed to design algorithms that address the fairness and transparency of the benefits of collaboration between people. In the industry, 99.9% of companies and projects do not design algorithms on any blockchain at all, just sending coins and speculating coins. Therefore, this liar does not blame the blockchain database, but only the liar uses the name of the blockchain.
