Online Review: Throughout human history, flow has been the core force of human transformation. From the earliest times, the flow of slaves in the primitive era, the flow of peasants, the flow of workers, the revolutionary blood flow, the shedding of blood, to the cultural flow of recorded written information on paper, the flow of ideas, the flow of knowledge, to the flow of information in the internet age, to the flow of value, money, and capital in the era of the blockchain value network... In summary, flow is the core; only the forms of flow are beginning to change. In short, as we move away from blood flow, civilization does not need to shed blood; shedding blood is not civilization.
