Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
With the coming of the scientific and technological era and the development of the mobile internet, the pace of network revolution is getting faster and faster, the information fusion of the same field or multiple fields is realized, and the process of providing an all-dimensional informatization scheme for customers also faces new challenges of improving the system structure, supporting gravity center transfer and the like. Therefore, the blockchain technology, as a specific implementation of the distributed ledger, is gradually becoming the preferred way to store data and transaction data in various fields by virtue of its natural advantages of storing and managing data.
The block chain network shown in fig. 1 is described as an example. As shown in fig. 1, the node devices in the block chain network may include banks, insurance companies, government buildings, shops, schools, hospitals, and the like. Banks, insurance companies, government buildings, shops, schools and hospitals all participate in the management and processing of the same blockchain network, and can also participate in monitoring the legality of transactions so as to achieve the fairness of processing or storing transaction data by the blockchain network. Meanwhile, the bank, the insurance company, the government building, the shop, the school and the hospital belong to different fields, and the quality and the efficiency of social work can be better improved through information fusion and interaction in the different fields. Any node device in the blockchain network may check the acquired transaction data, and when the obtained check result is that the check is successful, a block (such as the block shown in fig. 1) may be generated based on the transaction data and issued to the blockchain, so that each other node device in the blockchain network may perform distributed storage on the block. For example, as shown in fig. 1, the node devices in the block chain network may include banks, insurance companies, government buildings, shops, schools, and hospitals, and the banks, insurance companies, government buildings, shops, schools, and hospitals may store the identity information of the same user a in a distributed manner, so that the user a may query the identity information of any organization.
As shown in fig. 2, a data processing system provided for the embodiment of the present invention may be a distributed system formed by a client, a plurality of node devices (any form of computing devices in an access network, such as servers and user terminals) connected through a network communication form. The client may also be a node device in the blockchain network. The distributed system may be a blockchain system, and referring to fig. 2, fig. 2 is an alternative architecture diagram of the data processing system applied to the blockchain system (or blockchain network) according to the embodiment of the present invention, and the data processing system is formed by a client and a plurality of node devices. A point-To-point (P2P, Peer To Peer) network is formed among the node devices, and the P2P Protocol is an application layer Protocol operating on a Transmission Control Protocol (TCP). In a distributed system, any machine, such as a server or a terminal, can join to become a node, and the node comprises a hardware layer, a middle layer, an operating system layer and an application layer.
Referring to the functions of each node in the blockchain system shown in fig. 2, the functions involved include:
1) routing, a basic function that a node has, is used to support communication between nodes.
Besides the routing function, the node may also have the following functions:
2) and the Block chain comprises a series of blocks (blocks) which are mutually connected according to the generated chronological order, new blocks cannot be removed once being added into the Block chain, and recorded data submitted by nodes in the Block chain system are recorded in the blocks.
Referring to fig. 3, fig. 3 is an optional schematic diagram of a Block Structure (Block Structure) according to an embodiment of the present invention, where each Block includes a hash value of a data 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. A block chain (Blockchain), which is essentially a decentralized database, is a string of data blocks associated by using cryptography, and each data block contains related information for verifying the validity (anti-counterfeiting) of the information and generating a next block.
3) The application is used for being deployed in a block chain, realizing specific services according to actual service requirements, recording data related to the realization functions to form recording data, carrying a digital signature in the recording data to represent a source of task data, and sending the recording data to other nodes in the block chain system, so that the other nodes add the recording data to a temporary block when the source and integrity of the recording data are verified successfully.
For example, the services implemented by the application include:
3.1) a wallet for providing functions of transaction of electronic money, which includes initiating transaction (i.e. sending the transaction record of the current transaction to other nodes in the blockchain system, and storing the record data of the transaction in a temporary block of the blockchain as a response for confirming that the transaction is valid after the other nodes are successfully verified; of course, the wallet also supports the querying of the remaining electronic money in the electronic money address;
and 3.2) sharing the account book, wherein the shared account book is used for providing functions of operations such as storage, inquiry and modification of account data, the recorded data of the operations on the account data are sent to other nodes in the block chain system, and after the other nodes verify the validity, the recorded data are stored in the temporary block as a response for acknowledging that the account data are valid, and confirmation can be sent to the node initiating the operations.
3.3) Intelligent contracts, computerized agreements, which can execute the terms of a certain contract, are realized by codes deployed on a shared book for execution when certain conditions are met, and are used for completing automated transactions according to actual business requirement 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.
In the current block chain architecture, a developer defines a contract logic through a certain programming language to generate an intelligent contract, wherein the intelligent contract comprises a plurality of execution functions, and each execution function is used for realizing a specific function; the intelligent contract encapsulates a plurality of predefined states, conversion rules, trigger conditions, corresponding operations and the like; and then, issuing the intelligent contract to a block chain (contract registration), after each party signs, attaching the intelligent contract to block chain data in the form of program codes, and after the intelligent contract is transmitted and verified by a block chain network, recording the intelligent contract into a distributed account book of each node, wherein the block chain can monitor the state of the whole intelligent contract in real time, and activate and execute the contract after the intelligent contract meets a specific trigger condition. It can be seen that, in the current mode, an intelligent contract needs to be issued to a block chain first, and then after a trigger condition is met, a matched execution function in the intelligent contract is called and run to process transaction data. On one hand, the intelligent contract is named, the safety of a block chain can be influenced to a certain extent, the issuing process of the intelligent contract is complicated, and a large amount of network resources can be consumed; on the other hand, the process of calling the execution function of the smart contract may consume a long time, and may reduce the processing efficiency of the transaction data.
Based on this, an embodiment of the present invention provides a data processing method based on a block chain, including the following steps: receiving a transaction request sent by a client, wherein the transaction request comprises transaction data; acquiring an execution function of the intelligent contract matched with the transaction request; adding the acquired execution function into the transaction data to obtain target data; and issuing the target data to a block chain, and operating an execution function in the target data to process the transaction data in the issuing process. By the mode, on one hand, the time for acquiring the matched execution function in the uplink process can be saved, and the data processing efficiency is effectively improved; on the other hand, it is not necessary to issue an intelligent contract to the blockchain network, so that an anonymous intelligent contract can be implemented, and the blockchain security can be improved, which will be described in detail below.
Referring to fig. 4, fig. 4 is a flowchart illustrating a data processing method based on a block chain according to an embodiment of the present invention. The data processing method based on the blockchain described in the embodiment of the present invention may be applied to a node device, where the node device may be any node device in the blockchain network in the data processing system shown in fig. 2. In other embodiments, the node device is an optimal node device determined according to a load condition, a response time, and a distance from a client of each node device in the block chain network. The data processing method based on the block chain described in the embodiment of the invention comprises the following steps:
s401, receiving a transaction request sent by a client, wherein the transaction request comprises transaction data.
In the embodiment of the invention, the transaction data is data required to be used in the transaction execution process requested by the transaction request; the transaction request may be a data modification request, a data read request, a data write request, and the like. In one embodiment, the transaction request may be a funding transaction request, the transaction data including a payment blockchain account, a transaction amount, a checkout blockchain account, and the like. After receiving a transaction request sent by a client, the node device acquires transaction data carried by the transaction request.
S402, obtaining an execution function of the intelligent contract matched with the transaction request.
In the embodiment of the invention, the node equipment stores a plurality of execution functions of the intelligent contract and stores the mapping relation between various transaction requests and the execution function identification of the intelligent contract; the node equipment determines the target identification of the execution function matched with the received transaction request according to the mapping relation, and acquires the execution function matched with the target identification from various execution functions of the intelligent contract stored in the node equipment. For example, the transaction request is a fund transaction request, and the execution function required for executing the fund transaction is a fund transaction function, which includes a fund data modification function, a fund data reading function, and the like; the node device obtains the fund data modification function, the fund data reading function and the like from various execution functions stored by the node device.
In other embodiments, the manner in which the node device obtains the execution function of the smart contract that matches the transaction request is: detecting the transaction type to which the transaction data belongs, and acquiring an execution function of the intelligent contract matched with the transaction type; and taking the acquired execution function as an execution function matched with the transaction request. In one embodiment, the node device stores a plurality of execution functions of the intelligent contract and stores mapping relations between various transaction categories and execution function identifications of the intelligent contract; and the node equipment determines the target identification of the execution function matched with the transaction type to which the transaction data belongs according to the mapping relation, and acquires the execution function matched with the target identification from a plurality of execution functions of the intelligent contract stored in the node equipment.
In one embodiment, before acquiring the intelligent contract execution function matched with the transaction request, the node device acquires the data size of the intelligent contract execution function matched with the transaction request, and detects whether the data size is smaller than or equal to a preset value; if the data size is smaller than or equal to the predetermined value, steps S402 to S404 are performed. If the data size is larger than the preset value, acquiring a target identifier of an intelligent contract execution function matched with the transaction request, and adding the target identifier into the transaction data; and then, the transaction data added with the target identifier is issued to the blockchain, and an execution function matched with the target identifier is called and executed in the issuing process to process the transaction data. By adopting the mode, when the size of the acquired execution function exceeds a certain numerical value, only the identification of the execution function is added into the transaction data, so that the data volume on the block chain can be reduced to a certain extent, and the storage resource is saved.
In another embodiment, before the node device acquires the intelligent contract execution function matched with the transaction request, whether the client has the right to execute the transaction requested by the transaction request is detected; if it is detected that the client has the right to execute the transaction requested by the transaction request, steps S402 to S404 are executed. If the client side is detected not to have the authority for executing the transaction requested by the transaction request, the node device issues the transaction request to the blockchain, broadcasts a message that the transaction request does not have the authority to the nodes in the blockchain network, and/or adds an identifier without the authority to the transaction request in the blockchain network. By the method, whether the transaction requested by the transaction request is executed or not can be quickly verified.
And S403, adding the execution function into the transaction data to obtain target data.
In the embodiment of the invention, the execution function of the intelligent contract matched with the transaction request is one or more.

By adopting the mode, the corresponding execution functions can be found quickly when the execution functions are operated subsequently, and the data processing efficiency of the block chain is further improved to a certain extent.
S404, issuing the target data to a block chain, and operating an execution function in the target data to process the transaction data in the issuing process.
In the embodiment of the invention, the node equipment generates a block according to the target data, issues the generated block to the block chain, and runs the execution function in the target data to process the transaction data in the process of issuing the block to the block chain. Through the mode, the node equipment can directly run the execution function in the target data to process the transaction data in the data chaining process, and compared with the method that the matched execution function is obtained from the underlying intelligent contract module only in the data chaining process at present, the method and the device can save the time for obtaining the matched execution function in the data chaining process, so that the processing efficiency of the transaction data is improved. In addition, the execution function of the intelligent contract in the scheme does not need to be issued to the blockchain network, so that not only can network resources consumed by issuing the intelligent contract be saved, but also anonymous intelligent contracts can be realized, and the safety of the blockchain is improved to a certain extent.

And when the fund balance is smaller than the transaction amount, the node equipment cancels the operation of issuing the target data to the block chain and sends prompt information of transaction failure to the client. In other embodiments, after the node device cancels the operation of publishing the target data to the blockchain, the node device publishes the transaction request to the blockchain, broadcasts a message that the transaction request is not responded to the node in the blockchain network, and/or adds an identification that the transaction request is not responded to in the blockchain network. By the method, whether the transaction requested by the transaction request is executed or not can be quickly verified.
In one embodiment, before acquiring the fund balance of the payment blockchain account, the node device may further detect whether the transaction amount exceeds a limit of the payment blockchain account, where the limit may be a limit of an amount of a single transaction, a limit of an amount of a single day transaction, or the like. And if the transaction amount is detected not to exceed the limit of the payment blockchain account, executing the step of acquiring the fund balance of the payment blockchain account. And if the transaction amount is detected to exceed the limit of the payment blockchain account, the node equipment cancels the operation of issuing the target data to the blockchain and sends prompt information of transaction failure to the client. In other embodiments, after the node device cancels the operation of publishing the target data to the blockchain, the node device publishes the transaction request to the blockchain, broadcasts a message that the transaction request is not responded to the node in the blockchain network, and/or adds an identification that the transaction request is not responded to in the blockchain network. By the method, whether the transaction requested by the transaction request is executed or not can be quickly verified.
