Abstract:We have been developing permissioned blockchains (BC) since 2015 and encountered numerous issues. Some of these issues are well known, but some are unknown before. This paper summarizes these lessons learned including communication and consensus protocols. Even though communications protocols and consensus protocols have been under development and experimentation for over forty years, we still encountered issues not addressed before. These issues require innovative solutions to ensure that dependable BC will be operating at a high speed.
