Abstract

A blockchain system for power trading includes a transaction server running a transaction platform, and a server unit. When the server unit receives a charging request generated by a charging terminal, the server unit writes the charging demand into a distributed ledger. When the server unit receives from the trading platform a request for selling electricity including a sell content, the server unit determines whether there is a matched purchase content that matches the sell content among all the pending buy content announced on the trading platform. When it is determined that the matched purchase content exists, the server unit generates a first transaction pairing result and writes it into the distributed ledger based on the matched purchase content and the sell content.
