Steve Wozniak launches Efforce, a blockchain-based energy-saving platform
> The data that each smart meter will transmit will be validated and certified by the blockchain, so as to be able to unequivocally guarantee the savings obtained at a
certain point in time<p>Block chain doesn't validate things happening in the real world (energy saved, KWh consumed) only auditors/inspectors can do that.  The data from the smart meter can always be faked before it goes to the blockchain network.<p>Have I missed something? I'd be inclined to give Woz the benefit of the doubt on most things but I don't get what blockchain gives here apart from marketing BS - for which its a year or two behind the times?
