Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

Embodiments of the present application relate to blockchain technology and related terms and concepts of blockchain technology are briefly described below:

blockchain (Blockchain) is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, encryption algorithm and the like. The method is characterized in that the method is a decentralised database, which is a series of data blocks generated by correlation of a cryptography method, and each data block contains information of a batch of network transactions and is used for checking the validity (anti-counterfeiting) of the information and generating a next block. The blockchain may include a blockchain underlying platform, a platform product services layer, and an application services layer.

A blockchain network may be understood as a data sharing system 100, the data sharing system 100 may refer to a system for sharing data between nodes, and an exemplary architecture of the data sharing system 100 may be seen in fig. 1a; as shown in fig. 1a, a data sharing system 100 refers to a system for performing data sharing between nodes, where a plurality of nodes 1001 may be included in the data sharing system, and the plurality of nodes 1001 may be respective clients in the data sharing system. Each node 1001 may receive input information while operating normally and maintain shared data within the data sharing system based on the received input information. In order to ensure the information intercommunication in the data sharing system, information connection can exist between each node in the data sharing system, and the nodes can transmit information through the information connection. For example, when any node in the data sharing system receives input information, other nodes in the data sharing system acquire the input information according to a consensus algorithm, and store the input information as data in the shared data, so that the data stored on all nodes in the data sharing system are consistent. In the present application, after any one of the blockchain network nodes receives a transaction request, the transaction request is broadcasted in the blockchain network, and a plurality of transactions are packaged into a block by a block-out node (one of the blockchain network nodes) and broadcasted to other blockchain network nodes.

Each node in the data sharing system has a node identifier corresponding to the node identifier, and each node in the data sharing system can store the node identifiers of other nodes in the data sharing system, so that the generated block can be broadcast to other nodes in the data sharing system according to the node identifiers of the other nodes. Each node can maintain a node identification list shown in the following table, and the node names and the node identifications are correspondingly stored in the node identification list. Wherein the node identity may be an IP (Internet Protocol, protocol for interconnection between networks) address and any other information that can be used to identify the node; for example, the node identifier may also be a binary sequence code (e.g., 110001110), and table 1 is only illustrated by taking an IP address as an example:

TABLE 1

Node name	Node identification
		Node 1	yyy.yyy.yyy.yyy
Node 2	zzz.zzz.zzz.zzz
		…	…
Node X (X is a positive integer)	xxx.xxx.xxx.xxx

Each node in the data sharing system stores one and the same blockchain. The blockchain is composed of a plurality of blocks, see fig. 1b, the blockchain is composed of a plurality of blocks, the starting block comprises a block head and a block body, the block head stores an input information characteristic value, a version number, a time stamp and a difficulty value, and the block body stores input information; the next block of the starting block takes the starting block as a father block, the next block also comprises a block head and a block body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the father block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block chain are associated with the block data stored in the father block, and the safety of the input information in the block is ensured.

When each block in the blockchain is generated, referring to fig. 1c, when the node where the blockchain is located receives input information, checking the input information, after the checking is completed, storing the input information into a memory pool, and updating a hash tree used for recording the input information; then, updating the update time stamp to the time of receiving the input information, trying different random numbers, and calculating the characteristic value for a plurality of times, so that the calculated characteristic value can meet the following formula:

SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))<TARGET

wherein SHA256 is a eigenvalue algorithm used to calculate eigenvalues; version (version number) is version information of the related block protocol in the block chain; the prev_hash is the block header characteristic value of the parent block of the current block; the merkle_root is a characteristic value of input information; ntime is the update time of the update timestamp; the nbits is the current difficulty, is a fixed value in a period of time, and is determined again after exceeding a fixed period of time; x is a random number; TARGET is a eigenvalue threshold that can be determined from nbits.

Thus, when the random number meeting the formula is calculated, the information can be correspondingly stored to generate the block head and the block body, and the current block is obtained. And then, broadcasting the newly generated block to other nodes in the data sharing system according to the node identification of other nodes in the data sharing system by the node in which the block chain is positioned, performing common check on the newly generated block by the other nodes, and adding the newly generated block into the stored block chain after the common check is finished.

In this application, after each blockchain network node receives a block packaged by a block node, the transaction in the block starts to be executed. Specifically, the logic computation layer of each blockchain network node obtains the transaction parameters parsed from the uplink request, and executes at least one intelligent contract corresponding to the transaction parameters.

Further, after the execution of at least one intelligent contract corresponding to the transaction is completed, each blockchain network node performs mutual verification on the execution result; for example, the blockchain network node may organize the execution result or the change to the storage into a form of a merck (merkle) tree, put the tree root into the blockhead of the target block, and finally verify that the hash in the blockhead of the target block stored in each blockchain network node is consistent. After the verification is successful, each blockchain network node writes the data related to the target block into the storage, wherein the data related to the target block comprises at least one of the following: the block header of the target block, all transactions contained in the target block, and the intelligent contract execution results of each transaction.

Based on the above description about the blockchain network structure related to the embodiment of the present application, the following briefly describes a data processing scheme provided by the embodiment of the present application based on the blockchain network, which can improve the reliability of the execution result of the transaction. Referring to FIG. 1d, FIG. 1d is a block chain network based data processing system architecture diagram according to an embodiment of the present application. As shown in fig. 1d, the processing system may include: a service node 101 and a blockchain network node 102. One data processing method based on the blockchain network provided in the embodiments of the present application may be performed by the service node 101, and another data processing method based on the blockchain network may be performed by the blockchain network node 102. Service node 101 may include, but is not limited to: smart phones (such as Android phones, IOS phones, etc.), tablet computers, portable personal computers, mobile internet devices (Mobile Internet Devices, abbreviated as MID), vehicle terminals, and other smart devices, which are not limited in this embodiment of the present application. The blockchain network node 102 may be an independent physical server, a server cluster or a distributed system formed by a plurality of physical servers, or a cloud server providing cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDN (Content Delivery Network ), basic cloud computing services such as big data and an artificial intelligence platform, which is not limited in the embodiment of the present application.

It should be noted that, in fig. 1d, the service node 101 and the blockchain network node 102 may be directly or indirectly connected through a wired communication manner or a wireless communication manner, which is not limited herein. The number of service nodes 101 and blockchain network nodes 102 is for example only and does not constitute a practical limitation of the present application; for example, a service node 103 or the like may also be included in the data processing system.

It will be appreciated that in the detailed description of the present application, where the transaction provided by a service node is to be acquired, when the above embodiments of the present application are applied to a specific product or technology, the blockchain network node needs to acquire corresponding data acquisition rights (e.g., the service node 101 authorizes the blockchain network node 102), and the collection, use and processing of relevant data needs to comply with relevant laws and regulations of relevant countries and regions.

The general principle of a blockchain network-based data processing scheme is as follows:

(1) The service node 101 sends a request for the uplink of the transaction to the blockchain network node 102, and the blockchain network node 102 invokes at least one smart contract in the blockchain network to execute the transaction in response to the request for the uplink of the transaction. The transaction comprises data which need to be verified in a blockchain network; the transaction may include a virtual resource transfer record, and may also include certification information (e.g., an identification code for product A, a date of manufacture for product B, etc.). For example, let intelligent contract 1 and intelligent contract 2 be used to handle virtual resource transfer, intelligent contract 3 be used to check the validity of data, if transaction 1 is to transfer virtual resources in account a to account B, blockchain network node 102 invokes intelligent contract 1 and intelligent contract 2 to execute transaction 1; if transaction 2 is the certification of storage product a, blockchain network node 102 invokes smart contract 3 to perform transaction 2 (e.g., verify that the certification of storage product a is legitimate).

(2) The blockchain network node 102 records at least one contract execution information that is intelligent about in executing the transaction; wherein the contract execution information includes at least one of: the method comprises the steps of executing a contract, and executing a contract execution log, wherein the contract execution log comprises at least one piece of effective information which is generated in the process of executing a transaction intelligently; for example, at least one intelligence may be in close proximity to intermediate data generated during execution of the transaction, violation information of the transaction, and the like. In one embodiment, the blockchain network node 102 may record at least one contract execution information that is intelligent about in executing the transaction by invoking a contract recording function, wherein the contract recording function includes at least one of the following fields: a type field, an index field, a data field; the type field indicates the type of the contract execution information, and the index field screens the contract execution information.

(3) The blockchain network node 102 constructs a merck tree based on the contract execution information and adds the root node of the merck tree as check data of the contract execution information to the blockchain. Specifically, the blockchain network node 102 may add contract execution information to the to-be-stored set, where the to-be-stored set includes one or more contract execution information, and when it is detected that the to-be-stored set satisfies the storage condition (e.g., the number of contract execution information in the storage set reaches a number threshold), the blockchain network node 102 constructs a merck tree based on the one or more contract execution information in the to-be-stored set, and adds a hash value of a root node of the merck tree as verification data of the contract execution information to the target block. Alternatively, the blockchain network node 102 may also directly add the hash value of the contract execution information to the target block.

(4) The blockchain network node 102 returns contract execution information to the sender of the uplink request (e.g., the service node 101). In one embodiment, blockchain network node 102 returns contract execution information to service node 101 as response information to the uplink request. It should be noted that, the step (4) may also be performed before the step (3), or may be performed synchronously with the step (3), which is not limited in this application.

(5) After receiving the contract execution information returned by the blockchain network node 102, the service node 101 may obtain verification data of the contract execution information from the blockchain to verify the reliability of the contract execution information. In one embodiment, the verification data of the contract execution information includes hash values of a root node of a merck tree constructed based on the hash values of the contract execution information, the service node 101 acquires attestation information associated with the contract execution information returned by the blockchain network node, the attestation information includes one or more hash values associated with the hash values of the contract execution information, and the service node 101 obtains to-be-verified data corresponding to the contract execution information based on the contract execution information and the attestation information; for example, the service node 101 calculates a hash value of a root node of the merck tree (i.e., data to be verified) constructed based on the hash value of the contract execution information, based on the hash value of the contract execution information and one or more hash values associated with the hash value of the contract execution information. After obtaining the data to be verified corresponding to the contract execution information, the service node 101 obtains the verification data from the blockchain, verifies whether the verification data is matched with the data to be verified, and if the verification data is matched with the data to be verified, determines that the contract execution information passes the verification, namely the contract execution information is reliable.

Based on the video processing scheme, the embodiment of the application provides a more detailed data processing method based on the blockchain network, and the data processing method based on the blockchain network provided by the embodiment of the application will be described in detail with reference to the accompanying drawings.

Referring to fig. 2, fig. 2 is a flowchart of a data processing method based on a blockchain network, which may be performed by a computer device, which may be the blockchain network node 102 shown in fig. 1d, according to an embodiment of the present application. As shown in fig. 2, the data processing method may include the following steps S201 to S204:

s201, in response to a uplink request for a transaction, invoking at least one intelligent contract in a blockchain network to execute the transaction.

The transaction comprises data which need to be verified in a blockchain network; the transaction may include a virtual resource transfer record, and may also include certification information (e.g., an identification code for product A, a date of manufacture for product B, etc.). One transaction may correspond to one or more smart contracts in a blockchain network; for example, transaction 1 corresponds to intelligent contract 1 and intelligent contract 2 in the blockchain network, and transaction 2 corresponds to intelligent contract 3 in the blockchain network.

In one embodiment, in response to a request for a uplink to a transaction, a computer device invokes at least one smart contract in a blockchain network corresponding to the transaction to perform the transaction; for example, let intelligent contract 1 and intelligent contract 2 be used to handle virtual resource transfer, intelligent contract 3 be used to check the validity of data, if transaction 1 is to transfer the virtual resource in account a to account B, then the computer device calls intelligent contract 1 and intelligent contract 2 to execute transaction 1; if transaction 2 is the certification of storage product a, the computer device invokes smart contract 3 to perform transaction 2 (e.g., verifying that the certification of storage product a is legitimate).

S202, recording contract execution information of at least one intelligent contract in the process of executing the transaction.

The contract execution information includes at least one of: the method comprises the steps of executing a contract, and executing a contract execution log, wherein the contract execution log comprises at least one piece of effective information which is generated in the process of executing a transaction intelligently; the effective information may include at least one intelligent contract about intermediate data generated in the process of executing the transaction, and if the at least one intelligent contract detects that the transaction has violation information in the process of executing the transaction, the effective information may further include the violation information of the transaction, and the like.

In one embodiment, the computer device may record at least one contract execution information that is intelligent about in the course of executing the transaction by invoking a contract recording function, wherein the contract recording function includes at least one of the following fields: a type field, an index field, a data field; wherein the type field is used to indicate the type of contract execution information, the index field is used to filter the contract execution information, and the data field is used to store one or more valid information generated during execution of the transaction by the at least one intelligent entity. In practical applications, the recording function may be expressed as: lockcontext, logevent (name, drags, data); wherein name is a type field for indicating an event name; in one implementation, the event name indicated by the type field may correspond to an event function signature, which may indicate the type of transaction by name; topics is an index field that indicates the value to be indexed; in one implementation, the index field is a byte array having a length less than a length threshold.

S203, constructing the merck tree based on the contract execution information, and adding the root node of the merck tree as check data of the contract execution information to the blockchain.

The verification data of the contract execution information is used for verifying the authenticity of the contract execution information, the computer device can add the contract execution information to a to-be-stored certificate set, the to-be-stored certificate set comprises one or more contract execution information, when the to-be-stored certificate set is detected to meet a certificate storage condition (for example, the quantity of the contract execution information in the to-be-stored certificate set reaches a quantity threshold value), the computer device constructs a merck tree based on the one or more contract execution information in the to-be-stored certificate set, and the hash value of the root node of the merck tree is used as the verification data of the contract execution information to be added to a target block; for example, a merck tree is constructed based on the contract execution information, and a root node of the merck tree is added as check data of the contract execution information to a block header of a target block. Alternatively, the computer device may directly add the hash value of the contract execution information to the target block.

It can be appreciated that storing hash values of root nodes of the merck tree as check data of the plurality of contract execution information saves more memory space than storing hash values of the respective contract execution information separately.

Further, after generating the verification data of the contract execution information, the computer device may add the verification data to the target block; for example, the computer device may add the verification data to the tile header of the target tile.

Note that, when the verification data of the contract execution information is: when the verification data is stored in the block header of the target block, the block header of the target block at least comprises two hash values, and one hash value is the hash value of the merck tree constructed based on the hash values of a plurality of transactions (i.e. the hash value carried in the block header of the conventional block chain); the other is a hash value of the root node of the merck tree constructed based on hash values of the contract execution information, and by this hash value, the reliability of the contract execution information can be verified more conveniently.

S204, returning contract execution information to the sender of the uplink request.

In one embodiment, the computer device may return the contract execution information to the sender of the uplink request as response information to the uplink request. It should be noted that, step S204 may also be performed before step S203 or performed in synchronization with step S203, which is not limited in this application.

Referring to fig. 3, fig. 3 is a flowchart of another data processing method based on a blockchain network, which may be performed by a computer device, which may be the blockchain network node 102 shown in fig. 1d, according to an embodiment of the present application. As shown in fig. 3, the data processing method may include the following steps S301 to S309:

S301, at least one intelligent contract to be deployed is acquired.

An intelligent contract is a computer protocol that aims to propagate, verify, or execute contracts in an informative manner. In a blockchain network, a smart contract is a code that can be understood and executed by each blockchain network node in the blockchain network, by invoking the corresponding smart contract, the blockchain network node can execute any logic and get the result. In practice, smart contracts may be managed and used by transactions on the blockchain. Each transaction may be understood as a remote procedure call (Remote Procedure Call, RPC) request for the blockchain network. For ease of understanding, a smart contract may be understood as an executable program and a blockchain network may be understood as an operating system that provides a running environment for the executable program. It should be noted that, a blockchain network may include a plurality of intelligent contracts, where each intelligent contract is distinguished by a contract identifier (e.g., a contract ID, a contract name, etc.).

The intelligent contracts to be deployed may be broadcast to the computer devices by blockchain network nodes in the blockchain network or imported to the computer devices by participants in the blockchain network.

S302, deploying at least one intelligent contract to be deployed through the consensus of the blockchain network in response to the at least one intelligent contract to be deployed.

Responsive to the consensus of the at least one smart contract to be deployed over the blockchain network, the computer device deploys the at least one smart contract to be deployed; for example, if each blockchain network node in the blockchain network agrees to deploy the smart contract to be deployed, the computer device deploys the smart contract to be deployed.

S303, in response to the uplink request for the transaction, invoking at least one intelligent contract in the blockchain network to execute the transaction.

The specific embodiment of step S303 can refer to the embodiment of step S201 in fig. 2, and will not be described herein.

Fig. 4a is a schematic diagram of a transaction performed by invoking at least one smart contract in a blockchain network according to an embodiment of the present application. As shown in fig. 4a, a requestor (e.g., a service node) sends a request for a transaction to the remote procedure call (Remote Procedure Call, RPC) layer of each blockchain network node. The blockchain network nodes broadcast transactions to each other, and the out-block nodes (one of the blockchain network nodes) package a plurality of transactions into one block and broadcast the block to other blockchain network nodes. The selection of the block node may be set according to the actual requirement, which is not limited in this application, for example, the algorithm for determining the block node may be: the leader outputs blocks, alternately outputs blocks, competes with each other to output blocks, etc. After each blockchain network node receives a block packaged by the block out node, the transaction in the block starts to be executed. Specifically, the logic computation layer of each blockchain network node obtains the transaction parameters parsed from the uplink request, and executes at least one intelligent contract corresponding to the transaction parameters. It should be noted that, in the process of executing at least one intelligent contract corresponding to the transaction, the logic calculation layer may also read the data required in the storage; for example, in the process of executing at least one smart contract corresponding to transaction 1, the associated data in transaction 2 needs to be used; if there is associated data in transaction 2 in the store, the logical compute layer may read the associated data in transaction 2 from the store. Further, after the execution of at least one intelligent contract corresponding to the transaction is completed, each blockchain network node performs mutual verification on the execution result; for example, the blockchain network node may organize the execution result or the change to the storage into a form of a merck (merkle) tree, put the tree root into the blockhead of the target block, and finally verify that the hash in the blockhead of the target block stored in each blockchain network node is consistent. After the verification is successful, each blockchain network node writes the data related to the target block into the storage, wherein the data related to the target block comprises at least one of the following: the block header of the target block, all transactions contained in the target block, and the intelligent contract execution results of each transaction.

S304, recording contract execution information of at least one intelligent contract in the process of executing the transaction.

S305, if at least one intelligent contract detects that the uplink request does not meet the uplink condition in the process of executing the transaction, recording the violation information corresponding to the uplink request in a contract execution log.

In practical application, the uplink condition can be set based on practical requirements, which is not limited in the application; for example, assuming that transaction 1 is to transfer 100 virtual resources in account a to account B, and at least one intelligence is about to perform a transaction, if it is detected that the number of virtual resources in account a is less than 100 (i.e. the uplink request does not satisfy the uplink condition), then the violation information corresponding to the uplink request is recorded in the contract execution log as follows: the balance is insufficient; for another example, assuming that the transaction 2 is to store relevant parameters of the product a, at least one intelligent entity is configured to perform the transaction, and detect that there is a violation parameter in the relevant parameters of the product a (e.g., a value of the violation parameter does not belong to a preset value range, etc.), record, in a contract execution log, violation information corresponding to the uplink request as follows: there are violation parameters.

It is understood that step S305 may be performed synchronously during the process performed in step S304.

Optionally, if at least one intelligent contract detects that the uplink request does not meet the uplink condition in the process of executing the transaction, contract execution information corresponding to the uplink request is discarded.

S306, adding contract execution information into the to-be-stored certificate set.

The to-be-stored certificate set is used for storing contract execution information which needs to be uplink, the to-be-stored certificate set comprises one or more pieces of contract execution information, and the contract execution information in the to-be-stored certificate set belongs to the same block.

S307, when the stored evidence collection is detected to meet the evidence storage condition, constructing a merck tree based on one or more contract execution information in the stored evidence collection.

The collection to be deposited meets the depositing condition and comprises any one of the following: the current moment is matched with the preset evidence storage time, and the quantity of contract execution information in the evidence storage set reaches a quantity threshold.

In one embodiment, when the to-be-stored-certificate set is detected to meet the certificate storage condition, the computer equipment calculates hash values corresponding to all contract execution information in the to-be-stored-certificate set, and takes the hash values corresponding to all contract execution information as leaf nodes of the merck tree to construct the merck tree.

S308, taking the hash value of the root node of the Merker tree as check data of contract execution information, and adding the check data into a target block.

In one embodiment, the computer device uses the hash value of the root node of the merck tree as check data for the contract execution information and adds the check data to the chunk header of the target chunk.

FIG. 4b is a schematic diagram of adding verification data to a target block according to an embodiment of the present disclosure. As shown in fig. 4b, during execution of a transaction, at least one smart contract stores all generated valid information in contract execution information (TxResult). The computer device constructs a merck (merkle) tree based on a plurality of contract execution information (TxResult) in the set of credentials to be stored, and adds a hash value (roothash) of a root node of the merck tree to a block header (block header) of the target block along with other fields. It will be appreciated that the amount of contract execution information in fig. 4b is merely exemplary and does not constitute a practical limitation of the present application.

S309, the contract execution information is returned to the sender of the uplink request.

The specific embodiment of step S309 can refer to the embodiment of step S204 in fig. 2, and will not be described herein.

In one embodiment, if the uplink request for the transaction does not meet the uplink condition, the contract execution information corresponding to the uplink request is still added to the to-be-stored set, and the subsequent step of storing the contract is continued. That is, although the uplink request for the transaction is not uplink, the verification data of the contract execution information corresponding to the uplink request is uplink, and the uplink requester can verify the contract execution information returned by the computer device based on the verification data of the contract execution information in the blockchain, so as to ensure the reliability of the contract execution information.

Optionally, if the computer device receives the request for obtaining the certification information, returning the certification information associated with the contract execution information to the requester; for example, assuming that the verification data of the contract execution information is a hash value of the root node of the merck tree constructed based on the hash value of the contract execution information, the certification information associated with the contract execution information means: one or more hash values needed in calculating the hash value of the root node of the merck tree based on the hash value of the contract execution information.

According to the embodiment of the application, on the basis of the embodiment of fig. 2, the verification data of the contract execution information is uplink, so that the requesters of all uplink requests can verify the contract execution information based on the verification data of the contract execution information; by storing the check data of the contract execution information in the block header, the requester of each uplink request can read the check data of the contract execution information more conveniently, the contract execution information can be queried statically for a plurality of times, the influence of other uplink requests is avoided, and the risk of tampering of the contract execution information is reduced; the contract execution information of various types of smart contracts can be recorded through the recording function.

As shown in fig. 6, H (x) represents that x is hashed; assuming that the contract execution information is information d in fig. 6, the certification information associated with the contract execution information includes: h (c), H (ab), H (efgh); the process of calculating the data to be verified (H (abcdefgh)) corresponding to the contract execution information by the computer equipment is as follows: h (d) is calculated from the information d, H (cd) is calculated from H (c) and H (d), H (abcd) is calculated from H (ab) and H (cd), and H (abcdefgh) is calculated from H (abcd) and H (efgh).

S505, obtaining check data from the block chain.

S506, if the verification data are matched with the data to be verified, judging that the contract execution information passes the verification.

In one embodiment, if the verification data is consistent with the data to be verified, the computer device determines that the contract execution information passes the verification; accordingly, if the verification data is inconsistent with the data to be verified, the computer equipment judges that the contract execution information fails to pass the verification.

Optionally, the computer device may further provide contract execution information and certification information associated with the contract execution information to other terminal devices or servers to certify the reliability of the contract execution information.
