Unlike Bitcoin’s proof of work system, which provides for robust decentralization and individual security
Bitcoin's proof of work system does not provide for robust decentralisation, because it has no mechanism with which to enforce said requirement. Absent such a mechanism, regular market forces cause Bitcoin to become centralised wherever has the greatest competitive advantage, which is why 2/3rds to 3/4ths of all Bitcoin mining capacity was allowed to fall under the physical control of a single totalitarian regime until said regime kicked them out.
