On April 21, the General Research Institute published a blockchain weekly report. According to the report, the centralization of computing power clearly violates the original intention of BTC creation, and the security risks brought by this are also difficult to ignore. In addition to the problem of centralized power management, the huge resource consumption and efficiency problems caused by PoW mining have also caused the calculation of mining power to be criticized. In response to these problems, new consensus mechanisms have begun to emerge. While these new consensus mechanisms have solved some of the problems in the PoW consensus, they often introduce new problems, and the exploration of the consensus mechanism is far from over.
