13. The blockchain system of claim 12, wherein the blockchain service differentiation unit further includes a second resource service type determination module, the second resource service type determination module is configured to determine whether the resource service type related to the intelligent contract relates to an attribute of an object or information, and when it is determined that the resource service type related to the intelligent contract relates to the attribute of the object or information, mark the resource service type related to the intelligent contract as the non-exclusive resource service.
14. The blockchain system of claim 11, wherein the blockchain network node selection unit includes a compute node selection module configured to select any at least one credit node from the blockchain network as a compute node.
15. The blockchain system of claim 14, wherein the blockchain network node selecting unit further includes a block-out node selecting module, and the block-out node selecting module is configured to select any at least one of the computing nodes as a block-out node.
16. The blockchain system of claim 15, wherein the blockchain network node selection unit further comprises a master node selection module, and the master node selection module is configured to select any at least one out-of-block node or any at least one credit node as the master node.
17. The blockchain system of claim 16, further comprising a double-flower processing unit, wherein the double-flower processing unit is configured to determine a main chain block depth of the main nodes when at least two main nodes process the exclusive resource traffic, and then take a processing result of the main node with the largest main chain block depth as a valid result.
18. The blockchain system of claim 16, further comprising a synchronization unit configured to enable the deblocking node to synchronize the non-exclusive resource service according to a characteristic of the non-exclusive resource service, wherein the characteristic of the non-exclusive resource service includes at least one of a geographic characteristic, a trade alliance characteristic, an industry characteristic, a processing node credit rating characteristic, and a service money-related scale characteristic, so that the deblocking node facilitates the synchronization according to the at least one of the geographic characteristic, the trade alliance characteristic, the industry characteristic, the processing node credit rating characteristic, and the service money-related scale characteristic.
