Blockchain-based energy terminal data effective interaction method in microgrid system

The invention discloses a blockchain-based energy terminal data effective interaction method in a microgrid system. The method is characterized in that each energy terminal in the microgrid system performs data interaction based on a blockchain; the block ring chain comprises a creation block and a ring network formed by a plurality of historical blocks and new blocks, wherein historical blocks and new blocks are used for initiating transactions by energy terminals. Hash pointers are adopted among creation block, historical blocks and new blocks to directly point to and/or indirectly point tothe creation block, the historical blocks and the new blocks; and the new block of the new transaction initiated by the energy terminal performs consensus confirmation in the block ring chain networkby adopting an asynchronous communication consensus mechanism. The block chain technology is applied to the microgrid, each energy terminal node finally backs up all data in the system, point-to-pointdata security interaction
