【Abstract】In the current supervision mode of cross-border products, the government supervises insufficiently due to incomplete and untrustworthy risk data, non-autonomous and human intervened risk evaluation models. A smart contract-based risk warning blockchain symbiotic system is proposed to reform the issues of the current system. The system is a new third-party system that provides risk warning data services for the government. A permissioned blockchain ecosystem has been developed to provide open, equal, and credible services for the government and enterprises. A risk warning model is implemented by smart contracts to provide a non-intervention evaluation for cross-border products. The autonomy of the system is realized through smart contracts such as enterprise access audit, risk data acquisition, risk assessment and feedback. The system effectively improves the science and intelligence of supervision, cut down the customs clearance time and sampling proportion, and has been verified in the Administration of Inspection and Quarantine in Shanghai Airport.
