According to Babbitt news, on November 8, the 2019 World Blockchain Conference officially opened at the Wuzhen Internet International Convention and Exhibition Center. In this afternoon's "Digital Assets: Birth, Deduction and Evolution" theme forum, Zhang Li, vice president of Jianan Zhizhi, said that POW can be compared to four words: distribution according to work. POS is somewhat similar to the allocation of resources. I don't think POW is the best, POS is not good, but from a philosophical or socioeconomic point of view, the social result of resource allocation in general is stratification, any slave society and feudal society you see. All societies will be subverted after the class solidifies. I can see the future, I don’t think POS is good, but going down for a long time is the result, this will happen. I don't think that POW is the ultimate choice of the world. Everyone has only ten years of history in the blockchain industry. We have seen many new technical directions. I think the future is not just POW+POS, there are many new ways of consensus.
