The invention relates to a multi-party cross-chain system based on a relay chain, which comprises a service chain, a relay chain and a cross-chain gateway, and is characterized in that a cross-chain request execution sequence is firstly determined, and then the cross-chain gateway monitors update of a cross-chain trigger condition from the relay chain and starts to monitor a chain transaction; a cross-chain gateway sends an application chain transaction meeting a cross-chain triggering condition to a relay chain to generate a cross-chain request, a cross-chain management contract of the relay chain firstly performs related verification, after the cross-chain request is established, the cross-chain management contract on the relay chain controls execution of the cross-chain request, and the cross-chain management contract manages storage of to-be-executed chain calling information. And the cross-chain gateway monitors whether related chain calling exists in the storage or not, if yes, the cross-chain triggerin
