1. The block chain (Blockchain) is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism, an encryption algorithm and the like. The blockchain is essentially a decentralized database, which is a string of blocks associated by using cryptography, and transaction data of a batch of network transactions is recorded in each block for verifying the validity (anti-counterfeiting) of the transaction data and generating the next block. Referring to fig. 1, an optional schematic diagram of a block structure (blockastructure) in the present application is shown, where each block includes a hash value of a transaction record stored in the block (hash value of the block) and a hash value of a previous block, and the blocks are connected by the hash values to form a block chain. The block may include information such as a time stamp at the time of block generation.
In practical applications, the blockchain may include a blockchain underlying platform, a platform product service layer, and an application service layer. Wherein:

The platform product service layer provides basic capability and an implementation framework of typical application, and developers can complete block chain implementation of business logic based on the basic capability and the characteristics of the superposed business.
The application service layer provides the application service based on the block chain scheme for the business participants to use.
In practical application, the blockchain can be divided into three categories, namely a public chain, a private chain and a alliance chain, according to different access rights and management rights. Wherein:
the public chain is a block chain which can be read by all people, can initiate transactions by any person, can obtain effective confirmation of the transactions, and can be used for accounting and consensus processes by any person;
the private chain is a block chain which uses a block chain technology as a bottom layer accounting technology, and accounting nodes are private or private mechanisms and are not open to the outside;
the alliance chain is a block chain which is used by a specific group and limited third parties, a plurality of preselected nodes are designated as accounting nodes inside the block chain, the generation of each block is determined by all the preselected nodes, and the alliance chain has certain requirements on configuration and network environment of the consensus or verification nodes.
2. The blockchain system is a distributed system formed by connecting a client node and a plurality of service end nodes in a network communication mode. Referring To fig. 2A, in the blockchain system, a Peer-To-Peer (P2P) network is formed between the service end nodes, and the P2P Protocol is an application layer Protocol operating on top of a Transmission Control Protocol (TCP). Wherein:
the client node is an Application program (App) or Software Development Kit (SDK) which can support user registration of the blockchain service and can initiate a service request to the blockchain network according to a user operation.
The server node, which is a computing device running on the server side and can provide blockchain services for the client node, may be, but is not limited to: server, user terminal, etc. in practical applications, any computing device, such as server, user terminal, etc. may join the blockchain network to become a server node.
Referring to fig. 2B, the blockchain system may include different functional service end nodes, such as: the endorsement node is mainly responsible for checking and endorsement of transaction data such as transaction proposals and the like sent by the client node, and returning endorsement results and endorsement signatures to the client node; the sequencing node is mainly responsible for carrying out global sequencing and block packing on transaction data such as transaction results with endorsement results and endorsement signatures and the like sent by the client node and broadcasting the generated blocks to the endorsement node and the accounting node; the accounting node is mainly responsible for verifying the blocks broadcast by the sequencing node (including but not limited to endorsement policy verification, read-write set verification and the like), submitting the verified blocks into a block chain, updating a database, and maintaining state data and copies of an account book.
3. An intelligent contract, which is a computerized protocol, can execute the terms of a certain contract, is realized by codes which are deployed on a shared account and are used for executing when certain conditions are met, and is used for completing automated transactions according to actual business demand codes, such as inquiring the logistics state of goods purchased by a buyer and transferring the electronic money of the buyer to the address of a merchant after the buyer signs the goods; of course, smart contracts are not limited to executing contracts for trading, but may also execute contracts that process received information.
4. In the present application, in order to configure the priority for the intelligent contract corresponding to the service according to the importance degree of the service, negotiation determination may be performed by each user in the blockchain system, and the contract priority of the intelligent contract may be configured and stored in association when the user uploads, installs, and instantiates the intelligent contract.
In the application, different contract priorities can correspond to different transaction data processing queues and transaction processing speed limit information, wherein the transaction data processing queues are used for storing transaction data of each service under the corresponding contract priority; the transaction processing speed limit information is configured for the corresponding contract priority according to the maximum load capacity of the service end node, and is used for limiting the processing speed of the transaction data of each service under the contract priority, and may include but is not limited to: and in practical application, the sum of the transaction processing amount upper limits corresponding to the contract priorities in the speed limit period does not exceed the maximum load capacity of the service end node.
For example: referring to fig. 3, when a user uploads, installs, and instantiates an intelligent contract, the contract priority of the intelligent contract may be configured, and the contract priority may include, but is not limited to: high priority, normal priority and low priority, in practical application, the high priority, normal priority and low priority may respectively correspond to a transaction data processing queue, and may be a high priority processing queue, a normal priority processing queue and a low priority processing queue in turn, and the high priority, the normal priority and the low priority respectively correspond to one transaction processing speed limit information, assuming that the maximum load capacity of each service end node is the same, the transaction processing speed limit information corresponding to the high priority, the normal priority and the low priority can be 600 transaction data processed at the highest, 300 transaction data processed at the highest and 100 transaction data processed at the highest within 1 second of the speed limit period in turn, thus, the service end node can process the speed limit information according to the transaction corresponding to each contract priority, and processing the transaction data in the transaction data processing queue corresponding to the corresponding contract priority.
5. In the present application, the content of the transaction data is different according to different functions of the service end node, and specifically, if the service end node is an endorsement node, the transaction data may include, but is not limited to: a transaction proposal in a transaction endorsement request sent by a client; if the server-side node is a sequencing node, the transaction data may include, but is not limited to: and the transaction result, the endorsement signature and the like in the transaction sequencing request sent by the client.
After introducing the technical terms related to the present application, the following briefly introduces the application scenarios and design ideas of the embodiments of the present application.
At present, in a blockchain system, a transaction data uplink process is usually completed by calling an intelligent contract, the intelligent contracts of all services are equal, for a public chain, if the transaction data of an important service is expected to be rapidly uplink, the possibility of rapidly uplink of the transaction data of the important service can be accelerated in a manner of increasing transaction commission, and for an alliance chain, the problem of rapidly uplink of the transaction data of the important service cannot be effectively solved in a manner of increasing the transaction commission. Therefore, a transaction data processing method is proposed in the prior art, that is, a new service end node is added in a blockchain system, and transaction data of important services are processed by using the new service end node, for the whole blockchain system, the improvement effect of the processing efficiency of the transaction data of the important services is limited, and the operation and maintenance difficulty and cost of the blockchain system are improved along with the increase of the number of the new service end nodes.
Therefore, in order to solve the above problems, an embodiment of the present application provides a method for processing transaction data, and specifically, according to an importance degree of a service, a contract priority is configured for a corresponding intelligent contract, and corresponding transaction processing speed limit information is configured for different contract priorities, when a service end node processes transaction data, according to a contract identifier of an intelligent contract corresponding to the transaction data, the contract priority of the intelligent contract is determined to be a target contract priority, the transaction data is stored in a transaction data processing queue corresponding to the target contract priority, and the transaction processing speed limit information corresponding to the target contract priority is obtained, and transaction data in the transaction data processing queue is processed according to the transaction processing speed limit information. Therefore, by configuring contract priorities for different intelligent contracts, transaction data of services with different priorities can be processed, so that the problem that the processing efficiency of the transaction data of important services is low in the method for processing the transaction data according to the time sequence is solved on the premise of not increasing new service end nodes, and the problems of resource waste, operation and maintenance cost and difficulty improvement caused by adding new service end nodes are avoided. Moreover, the corresponding transaction processing speed limit information is configured for different contract priorities, so that the transaction data of services with different priorities can be processed at different processing speeds, the processing efficiency of the transaction data of important services is guaranteed, and the flexibility of transaction data processing in the blockchain system is improved.
The following describes a transaction data processing method applied to a service end node in a blockchain system according to an embodiment of the present application. Referring to fig. 4, a flow of the transaction data processing method according to the embodiment of the present application is as follows:
step 401: acquiring to-be-processed transaction data and contract identification of an intelligent contract corresponding to the transaction data.
In practical application, if the service end node is an endorsement node, the transaction data to be processed and the contract identifier of the intelligent contract corresponding to the transaction data can be obtained from the received transaction endorsement request; if the service end node is a sequencing node, the transaction data to be processed and the contract identifier of the intelligent contract corresponding to the transaction data can be obtained from the received transaction sequencing request.
Step 402: and determining the contract priority of the intelligent contract as the target contract priority according to the contract identification of the intelligent contract.
In practical application, when a user uploads, installs and instantiates an intelligent contract, after the contract priority of the intelligent contract is configured according to the priority result negotiated by each user in a block chain system based on the importance degree of a service, the contract identifier and the contract priority of the intelligent contract can be stored in an associated manner, so that after the service end node obtains the contract identifier of the intelligent contract corresponding to transaction data, the service end node can obtain the contract priority of the intelligent contract according to the association relationship between the contract identifier and the contract priority and determine the contract priority as a target contract priority.
Step 403: and storing the transaction data to a transaction data processing queue corresponding to the target contract priority.
In practical application, in order to quickly process transaction data of each service corresponding to different priorities and improve the processing efficiency of the transaction data, the service end node acquires the transaction data to be processed, and after determining the contract priority of the intelligent contract corresponding to the transaction data as the target contract priority, the service end node can store the transaction data into the transaction data processing queue corresponding to the target contract priority.
Step 404: and acquiring the transaction processing speed limit information corresponding to the target contract priority, wherein the transaction processing speed limit information comprises the upper limit of the transaction processing amount in the speed limit period.
In order to improve the resource utilization rate, in this embodiment of the application, transaction data of a service with a lower contract priority may be processed in an idle time, specifically, before the service end node acquires transaction processing speed limit information corresponding to a target contract priority, it may also be checked whether the target contract priority is not lower than a priority threshold, if it is determined that the target contract priority is not lower than the priority threshold, the transaction processing speed limit information corresponding to the target contract priority may be directly acquired, and transaction data in a transaction data processing queue corresponding to the target contract priority is processed according to the transaction processing speed limit information, so that real-time processing of the transaction data of a high-priority service is ensured, and processing efficiency of the transaction data of the high-priority service is improved.
It is worth mentioning that, if the service end node determines that the target contract priority is lower than the priority threshold, the service end node may further detect whether the transaction data processing queues corresponding to the contract priorities not lower than the priority threshold are all empty, if so, the transaction data in the transaction data processing queues corresponding to the target contract priority may be directly processed, if not, the transaction data in the transaction data processing queues corresponding to the target contract priority may not be processed, and the transaction data processing queues corresponding to the contract priorities not lower than the priority threshold are monitored in real time, and when it is monitored that the transaction data processing queues corresponding to the contract priorities not lower than the priority threshold are all empty, the transaction data in the transaction data processing queues corresponding to the target contract priority is processed, so as to implement the function of processing the transaction data of the low-priority service in idle time, processing resources of the service end node are saved.
Further, when the service end node processes the transaction data in the transaction data processing queue with the low contract priority in idle time, if it is monitored that the transaction data processing queue corresponding to any contract priority not lower than the priority threshold is not empty, the processing of the transaction data in the transaction data processing queue with the low contract priority can be suspended, and the transaction data in the transaction data processing queue corresponding to any contract priority can be processed according to the transaction processing speed limit information corresponding to any contract priority, so that the real-time processing of the transaction data of the high-priority service is further ensured, and the processing efficiency of the transaction data of the high-priority service is improved.
