POWER METERING APPARATUS POWER METERING SERVER AND POWER METERING METHOD BASE ON BLOCK CHAIN

摘要

The present invention relates to a power metering device, a power metering server, and a block chain-based power metering method. Specifically, to ensure the integrity and transparency of power metering data based on a block chain, The power metering data and unique key are stored in a database that works with the power metering server, and the electronically signed hash value of the power metering data is stored in a separately configured block chain node. Accordingly, the present invention is a blockchain-based power metering system for preventing forgery and falsification of power metering data and at the same time solving a block chain storage capacity problem that may occur when storing power metering data, and protecting sensitive information of power metering data and methods thereof.
