Problems solved by technology
[0004] It can be seen that in the business processing process of the existing blockchain, before the blockchain nodes compete for bookkeeping rights, each blockchain node in the blockchain network can process business requests, and the business processing nodes are not limited but , in some application scenarios, for example, for a transaction task, the user may wish to only submit it to nodes that meet certain conditions to complete the processing, so the existing blockchain business processing methods cannot meet the needs of directional designated business processing nodes Business scenarios, expanding the choice of blockchain

Embodiment Construction
[0053] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0054] The embodiment of the present invention provides a business processing method based on blockchain, which can be applied to figure 1 In the network framework shown. The network framework includes clients, business nodes and consensus nodes, both of which are located in the blockchain. figure 1 It is just a schematic illustration, and the number of business nodes and consensus nodes is not limited here. The service node in the embodiment of the present invention can be used only as a service node, or can be used as a service node and a consensus node at the same time. Consensus nodes can be used only as consensus nodes, or as business nodes and consensus nodes at the same time. The business node is connected to any device that ...

The invention discloses a service processing method and a system based on a block chain, wherein, the method comprises the following steps: a service node receives a service request sent by a client end, and the service request comprises an acceptance condition; determining whether the service attribute information of the service node includes content matching with the acceptance condition; if yes, processing the service request to generate service data. The service node sends a preprocessing block including the service data to the consensus node. The consensus node performs consensus verification on the preprocessing block; if the preprocessing block passes consensus verification, the service node stores the preprocessing block into a block chain. The invention directionally designates aservice node for processing the service request by stipulating the acceptance condition of the service request, so that the service to be processed in the block chain can be executed within the scopeof the qualified service node according to the expectation of the requesting party, and the service node for processing the service request in the block chain is avoided from being constrained by therequesting party.
Description
technical field [0001] The present invention relates to the technical field of blockchain, in particular to a business processing method and system based on blockchain. Background technique [0002] As an emerging technology, blockchain technology has become a technology that people focus on due to its advantages such as openness, non-tampering, and decentralization. [0003] In the business processing process of the existing blockchain, the business request generated by the client can be broadcast on the entire network through P2P technology, and each blockchain node in the blockchain network can receive the business request and make a request for the business Requests are processed to generate business data. Each blockchain node broadcasts the business data generated by itself to other blockchain nodes, and then all blockchain nodes compete for bookkeeping rights through a consensus mechanism, and the blockchain nodes that compete for bookkeeping rights can share the busi...
