Fig. 2 is a schematic flowchart of a service processing method based on a block chain according to an embodiment of the present application, and is applied to a block chain gateway, as shown in fig. 2, the method includes:
s101: and receiving a block chain service request sent by the client during the received service operation input by the user.
The block chain service request comprises the following steps: identification of the target business object.
For example, in some possible embodiments, after receiving the blockchain service request, the blockchain gateway needs to analyze the received blockchain service request, and determine the identifier of the target service object according to an analysis result; the identifier of the target service object may be, for example, an Identity Document (ID) of the target service object, a timestamp corresponding to the target service when the target service is established, and the like, which may uniquely indicate the identifier information of the target service object.
S102: and determining a target block chain from a plurality of block chains of the block chain network according to the identification of the target service object.

S103: and sending a block chain service request to any block chain link point on the target block chain.
And the block chain service request is used for enabling any block chain node point to determine a service execution result of the block chain service request through a preset intelligent contract according to the identification of the target service object, and returning the service execution result to the client.
In an embodiment of the present application, the preset intelligent contracts are pre-deployed on block chains, each block chain has a corresponding preset intelligent contract, at least one block chain link point belonging to the same block chain corresponds to the same preset intelligent contract, and each preset intelligent contract is about a service parameter of a service object corresponding to the block chain link point.
By adopting the block chain-based service processing method provided by the application, after receiving the block chain service request, the block chain gateway determines a target block chain from a plurality of block chains in the block chain network according to the identification of a target service object in the block chain service request, and sends a service request to any block chain node on the target block chain, so that the block chain node receiving the service request can determine the service execution result of the block chain service request according to the identification of the target service object and a preset intelligent contract, and feeds back the service execution result to the client; in the processing method, the blockchain network is a decentralized network, so that the service execution results of the preset intelligent contract and the service request can not be changed by any third party, the accuracy and the irreplaceability of the preset intelligent contract and the service execution results are ensured, the multi-chain setting of the blockchain network can improve the throughput and the performance in the service processing process, and the effects of high concurrency and high throughput are achieved.
Optionally, on the basis of the foregoing embodiment, an embodiment of the present application may further provide a service processing method based on a block chain, and an implementation process of determining a target block chain in the foregoing method is described as follows with reference to the accompanying drawings. Fig. 3 is a flowchart illustrating a service processing method based on a block chain according to another embodiment of the present application, and as shown in fig. 3, S102 may include:
s104: and determining at least one block chain supporting the target business object from the plurality of block chains according to the identification of the target business object.
In some possible embodiments, at least one block chain is determined from the plurality of block chains according to the identifier of the target service object and the corresponding relationship between the target service object and the block chain address, where the number of the at least one block chain may be represented by goodsChainCount.
For example, in some possible embodiments, the correspondence between the target service object and the blockchain address may be, for example, a correspondence between an object and a blockchain address of each service, which is specified in advance and deployed on the blockchain gateway, and may be configured in advance for the operation and maintenance staff, for example, the blockchain a may robustly purchase the second-killing service 1, and the number of the second-killing services is 100; the block chain B can carry out the first-time purchase second-time killing of the business 1, and the number of the business is 100; the block chain C can carry out the first-time purchase second-time killing of the business 2, and the number of the business is 100; and the blockchain D can be used for killing the business 2 in seconds, and the quantity is 100.
The block chain gateway stores the corresponding relation between each service object and the block chain address in advance, the corresponding relation exists between each service object and at least one block chain address, and each block chain can only execute the block chain service request corresponding to the service object which has the corresponding relation with the block chain.
In another embodiment of the present application, for example, a goodsChainList may be further stored in the block chain gateway, where the goodsChainList is used to represent a correspondence between block chain addresses and preset intelligent contracts, for example, the correspondence may be stored in a state where each block chain has at least one corresponding preset intelligent contract, the preset intelligent contract is pre-deployed on each block chain, and at this time, the content recorded in the block chain gateway may be, for example: service 1: (chain a-preset intelligent contract 1, chain B-preset intelligent contract 2); service 2: (chain C-Preset Intelligent contract 3, chain D-Preset Intelligent contract 4).
Taking the second killing service as an example, the corresponding relationship between the block chain address recorded in the block chain gateway in the initialization stage and the preset intelligent contract is exemplified, because the second killing service only provides a preset number of second killing service objects on each block chain of the preset intelligent contract, that is, on the block chain deployed with the preset intelligent contract, only the preset number of second killing service objects can be subjected to service processing, at this time, the content recorded in the block chain gateway may be, for example: second killing service 1: (chain a-number 100-preset intelligent contract 1, chain B-number 100-preset intelligent contract 2); the second killing service 1 is represented to only provide 100 second killing service 1 service objects on the chain A and the chain B respectively, namely the chain A and the chain B can only perform service processing on the 100 second killing service 1 service objects; second killing service 2: (chain C-number 100-preset intelligent contracts 3, chain D-number 100-preset intelligent contracts 4); the second killing service 2 only provides 100 second killing service 2 service objects on the chain C and the chain D respectively, namely the chain C and the chain D can only perform service processing on the 100 second killing service 2 service objects; the determination of the target blockchain will be performed according to the recorded content, it should be understood that the above embodiment is merely an example, and the content and the recording form recorded in the specific blockchain gateway can be flexibly adjusted according to the user's needs, and are not limited to the above embodiment.
S105: a target blockchain is determined from the at least one blockchain.
For example, in an embodiment of the present application, the determining at least one blockchain of the target business object may be, for example, performing remainder calculation on an identifier of the target business object, and determining the target blockchain from the at least one blockchain according to a calculation result; in addition, the block chain service request further comprises: the identity information of the user, namely the mode of determining at least one block chain of the target business object, can also be used for carrying out remainder calculation on the identity information of the user, and determining the target block chain from the at least one block chain according to the calculation result; it should be understood that the above embodiments are only exemplary, and specifically determine the manner of the target block chain of the target business object.
In some possible embodiments, for example, a hash value corresponding to the identifier of the target service object may be determined according to the identifier of the target service object, and then the hash value is subjected to remainder calculation, and a target block chain is determined from at least one block chain according to a calculation result; the remainder calculation method may be, for example, (hash% goodsChainCount of the target service object), so as to obtain the designated fragment fragNum, that is, the target block chain, and then query the service block chain list goodsChainList according to the target service object, so as to know that the block chain service request corresponding to the target service object needs to be sent to the block chain at the fragNum position at this time, and any block chain node in the block chain assigned to the fragNum position executes the block chain service request, and determines the service execution result corresponding to the block chain service request.
Illustratively, after determining the target blockchain, the blockchain gateway sends a blockchain service request to any blockchain link point on the target blockchain, so that each blockchain link point receiving the blockchain service request executes the blockchain service request according to eckillGoods (address _ address), and determines an execution result of the blockchain service request.
By adopting the block chain-based service processing method provided by the application, the block chain network manager determines the target block chain from the plurality of block chains in the block chain network according to the identification of the target service object in the block chain service request, and sends the block chain service request to any block chain link point on the target block chain, so that the plurality of block chains in the block chain network can execute each block chain service request in parallel according to the plurality of block chain service requests sent by the block chain gateway, thereby playing a role in improving throughput and performance.
Optionally, on the basis of the foregoing embodiment, an embodiment of the present application may further provide a service processing method based on a block chain, and an implementation process of the foregoing method is described as follows with reference to the accompanying drawings. Fig. 4 is a schematic flowchart of a service processing method based on a blockchain according to another embodiment of the present application, which is applied to any blockchain node on a target blockchain in a blockchain network, where the blockchain network includes: a plurality of block chains; as shown in fig. 4, the method may include:

For example, in an embodiment of the present application, for example, a preset intelligent contract may be deployed on each block chain by using an initialization call method, where the initialization call method may be, for example, a parameter included in each preset intelligent contract of goodseckill (string _ goodsName, int32 _ goodsumber, string _ goodsDetail, int32 _ goodsCount), and may be, for example: the service name, the identification of the service object and the service details; if the service is a second killing service, the preset intelligent contract further comprises the residual second killing quantity of the second killing service.
In one embodiment of the present application, the service parameters may include, for example: parameters such as service name, service identifier, service details, etc., it should be understood that the above implementation is only an exemplary illustration, and the content included in the specific service parameter is not limited to the content given in the above embodiment.
