Abstract: Carbon emission permit（hereinafter referred to as carbon）trading is a market and policy tool to promote the
practice of low-carbon emission and energy conservation in China. In order to stimulate the market circulation of carbon
trading，guide market players to respond proactively，control greenhouse gas emissions，and actively respond to national
strategies，a "many to many" carbon trading application was proposed based on consortium blockchain technology. Firstly，
the application process and architecture of carbon trading system were designed according to the technical characteristics of
consortium blockchain. Secondly，the application and mechanism of carbon trading were designed，and the execution logic
of carbon trading based on consortium blockchain was proposed. Then，the mathematical model of carbon trading was
proposed，and the trading matching method was pointed out.Finally，the carbon trading mechanism and model designed
were verified by an example. Through the example，it can be seen that the carbon trading mechanism proposed has
advantage in marketing compared with the traditional wholesale marketing，which can improve the interests of market
players in the carbon trading and provide a reference for the construction of carbon market.
