Abstract
A power metering apparatus, a power metering server, and a power metering method based on a blockchain are disclosed. Particularly, in order to simultaneously assure integrity and transparency of power metering data based on a blockchain, power metering data generated by measuring an amount of power generated by an energy source and a unique key are stored in a database linked to a power metering server, and a digitally signed hash value of the power metering data is stored in a blockchain node. Accordingly, disclosed are blockchain-based power metering system and method for preventing forgery and tampering of power metering data, solving a problem associated with a blockchain storage capacity that may occur when storing the power metering data, and protecting sensitive information on the power metering data.
