Power transaction method, device and system based on blockchain technology

Abstract

One or more embodiments of the present specification provide a power transaction method based on blockchain technology, which combines a power grid blockchain and an edge computing network with each other and uses an edge server as part of blockchain nodes to reduce the deployment cost of the network, and at the same time, as the power grid has abundant power resources, which can be used as exchange resources for resource exchange with the nodes of an edge server so that maintenance cost of a blockchain network can be further reduced. Besides, the transaction chaining process is divided into three stages of transaction endorsement, sorting and verification, and different nodes serve as different roles, so that parallel processing of power transactions can be realized, and the transaction speed of the power transactions is increased. In addition, only authorized nodes in the blockchain network can join in the network and modify the data, so that the privacy of the data can be guaranteed. Therefore, the invention can reduce the cost of the blockchain network on the premise of ensuring the privacy and transaction speed of the data.

Description

technical field [0001] One or more embodiments of this specification relate to the technical field of the Internet of Things, and in particular to a power trading method, device and system based on blockchain technology. Background technique [0002] With the development of science and technology, smart grid, as an inevitable trend of future grid development, is integrated by highly robust information and communication technology (ICT), aiming to minimize cost, resource waste and environmental impact. Guarantee the electricity demand of consumers. The blockchain is an underlying information technology of a distributed system that cannot be tampered with. It has strong internal consistency with the construction of smart grids based on marketization, distributed energy and energy Internet. They all emphasize decentralization, autonomy, Marketization and intelligence. In the smart grid, if the blockchain can be effectively used, it can solve many practical problems, such as: ...

AI Technical Summary

Problems solved by technology

[0003] Some existing power grid blockchain research is mostly based on existing consensus mechanisms and public chains, such as Bitcoin and Ethereum. The data on the chain is completely open, and the confirmation time of a single transaction is relatively long, which is not satisfied with the power data. Requirements for Privacy and Transientity of Transactions

The decentralization, safe and stable operation of the public chain requires the deployment of a large number of distributed devices supported by sufficient computing power and storage units. For grid operators and users, huge costs need to be borne
