We explain how the CAP (Consistency, Availability, Partition tolerance) theorem known for databases influenced the DCS (Decentralization, Consistency, Scalability) theorem for the blockchain systems. ...
By using an analogous relaxation approach as it was used for the proof of the CAP theorem, we postulate a "DCS-satisfiability conjecture." ...
In more details, CAP theorem identifies the three specific system properties for any distributed/decentralized system. ...

There has been recent interest in using these Energy Storage Devices (ESDs) for demand-response (DR) to either shift peak demand away from high tariff periods, or to shave demand allowing aggressive under-provisioning ...
With a few exceptions, we find that our power demands fall into seven different clusters, and we present the ESD configuration for each cluster. ...
