Detailed Description

In order that those skilled in the art will better understand the present application, a technical solution in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, shall fall within the scope of the present application.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present application and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the application described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or server that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed or inherent to such process, method, article, or apparatus, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

First, technical terms related to the embodiments of the present application will be described:

a proof of Work (POW): is a consensus mechanism for blockchains. Refers to an algorithm in a blockchain system that determines permissions based on the contribution each node makes during the operation. In a blockchain network constructed based on a workload certification mechanism, the ability of a node to solve for the correct value solution to generate a block by computing the value solution of a random hash to contend for the accounting right is a concrete manifestation of the node's computing power.

Proof of rights mechanism (POS): the rights and interests proving mechanism requires that the prover provide ownership of a certain number of encrypted virtual resources. The equity proof mechanism operates in such a way that when creating a new block, the mineworker needs to create a "virtual resource" trade, which sends some virtual resources to the mineworker itself in a predetermined proportion. The rights and interests proving mechanism reduces the difficulty of obtaining the virtual resources of the nodes in equal proportion according to the proportion and time of each node having the virtual resources and the algorithm, thereby accelerating the speed of searching the random numbers.

Smart Contract: is a set of digitally defined commitments including agreements on which the contract participants can perform these commitments.

FIG. 1 is a schematic diagram illustrating an implementation environment of a data transfer processing method according to an exemplary embodiment. As shown in fig. 1, the implementation environment may at least include a client 01, an endorsement node 02, a consensus node 03, and the like, where the client 01, the endorsement node 02, and the consensus node 03 may be directly or indirectly connected through a wired or wireless communication manner, and embodiments of the present application are not limited herein.

Specifically, the client 01 may be configured to send a current data transfer request to the target endorsement node. Alternatively, the client 01 may include, but is not limited to, a cell phone, a computer, an intelligent voice interaction device, an intelligent home appliance, a vehicle-mounted terminal, an aircraft, etc. The embodiment of the application can be applied to various scenes, including but not limited to cloud technology, artificial intelligence, intelligent transportation, auxiliary driving and the like.

Specifically, the endorsement node 02 may be configured to execute an intelligent contract corresponding to the current data transfer request in response to the current data transfer request, to obtain a current contract execution result including the current data transfer read-write set, and to send the current contract execution result to the consensus node.

Specifically, the consensus node 03 may be configured to perform data transfer conflict detection on a current data transfer read-write set to obtain a current detection result including a first current data transfer operation set; and the method is used for creating a current new block, packaging the first current data transfer operation set into the current new block, and transmitting the packaged current new block to other nodes in the current blockchain network.

Alternatively, the endorsement node 02, the consensus node 03 may be a separate physical device, a physical server. Or may be a server cluster or a distributed system formed by a plurality of physical servers. The cloud server can also provide basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communication, middleware services, domain name services, security services, CDNs, big data, artificial intelligent platforms and the like.

It should be noted that fig. 1 is only an example. In other scenarios, other implementation environments may also be included.

Fig. 2 is a flowchart one of a data transfer processing method according to an exemplary embodiment. The method may be used in the implementation environment of fig. 1. The present specification provides method operational steps as described above, for example, in the examples or flowcharts, but may include more or fewer operational steps based on conventional or non-inventive labor. The order of steps recited in the embodiments is merely one way of performing the order of steps and does not represent a unique order of execution. When implemented in a real system or server product, the methods illustrated in the embodiments or figures may be performed sequentially or in parallel (e.g., in a parallel processor or multithreaded environment). As shown in fig. 2, the method may include:

S101, the client sends a current data transfer request to a target endorsement node.

Optionally, an endorsement node exists in the blockchain network, and the endorsement node may refer to a node selected to take on an endorsement task in the blockchain network. The "endorsement" can be understood as a process and a mechanism for carrying out data transfer verification on the data transfer of the blockchain network by the node bearing the endorsement task and declaring the data transfer legal for the data transfer operation passing the verification.

Illustratively, the data transfer in the embodiments of the present application may be a transaction, and the data transfer request may be a transaction request.

Optionally, the embodiment of the present application may send the current data transfer request to the target endorsement node in various manners, which is not specifically limited herein.

In one embodiment, in the case that the endorsement node in the blockchain network is one, the client may directly send the current data transfer request to the endorsement node through a wired or wireless transmission manner.

In an alternative embodiment, fig. 3 is a flowchart illustrating a client sending a current data transfer request to a target endorsement node according to an exemplary embodiment, where, as shown in fig. 3, the current blockchain network includes a plurality of endorsement nodes, and in step S101, the client sending the current data transfer request to the target endorsement node may include:

S1011, the client sends a current data transfer request to the current blockchain network, wherein the current data transfer request carries an endorsement policy of an intelligent contract and a data transfer hash value corresponding to the current data transfer request.

S1013, the current blockchain network responds to the current data transfer request, and determines a target endorsement node from the endorsement nodes based on an endorsement policy and a data transfer hash value.

S1015, the current blockchain network sends a current data transfer request to the target endorsement node.

Alternatively, in the case where a plurality of endorsement nodes are included in the current blockchain network in step S1011 described above, the client may first send a current data transfer request to the current blockchain network. FIG. 4 is a schematic diagram illustrating related data involved in a data transfer operation, according to an exemplary embodiment, as shown in FIG. 4, the current data transfer request may carry an endorsement policy of a smart contract, a data transfer hash value corresponding to the current data transfer request, a data transfer identification (Identity Document, ID), a smart contract that needs to be invoked, a method that needs to be invoked, a list of data transfer related parameters (e.g., keys, key values), an initiator that initiated the data transfer request, a signature of the initiator that initiated the data transfer request, etc.

Wherein the data transfer hash value refers to a character segment required for marking data transfer in data transfer of the blockchain network, which can be expressed by a series of letters, numbers or other symbols. For example, if a plurality of resources need to be transferred from the a address to the B address, the private key signature can be performed by using the a address, the signature is combined with the data transfer, and then the hash value operation is performed to obtain the data transfer hash value.

Optionally, there is an "endorsement policy" setting in the global configuration of the blockchain network or in the function call configuration of the smart contracts, i.e. the endorsement policy of the smart contract may provide a default configuration of the blockchain global, or the endorsement policy of the smart contract may be set in each smart contract separately. An "endorsement policy" describes how many endorsement nodes are required to execute and sign endorse the execution result after a data transfer request is broadcast to the endorsement nodes.

Illustratively, the endorsement policy of the smart contract may be set by an administrator of the contract (e.g., a contract installer), and includes the following three modes: any three kinds of endorsement strategies, all endorsement strategies, most endorsement strategies and the like, and the endorsement strategies can be changed at any time. The endorsement policy change is also realized through data transfer, the new policy can be validated after the data transfer is correctly packaged, and the data transfer is verified and executed according to the new policy. Any endorsement policy refers to selecting any endorsement node from a plurality of endorsement nodes to execute a corresponding intelligent contract, all endorsement policies refer to executing corresponding intelligent contracts by the plurality of endorsement nodes, and most endorsement policies refer to selecting more than half of endorsement nodes from the plurality of endorsement nodes to execute corresponding intelligent contracts.

Optionally, in the step S1013, the current blockchain network may determine the target endorsement node from the plurality of endorsement nodes based on the endorsement policy and the data transfer hash value when receiving the data transfer request.

Assuming that the endorsement policy is any endorsement policy, the current blockchain network may determine, from a plurality of endorsement nodes, a preset number of endorsement nodes corresponding to the data transfer hash value according to the data transfer hash value, and use any one of the preset number of endorsement nodes corresponding to the data transfer hash value as a target endorsement node.

Assuming that the endorsement policy is an all-endorsement policy, the current blockchain network may determine, from a plurality of endorsement nodes, a preset number of endorsement nodes corresponding to the data transfer hash value according to the data transfer hash value, and take all of the preset number of endorsement nodes corresponding to the data transfer hash value as target endorsement nodes.

Assuming that the endorsement policy is a majority of the endorsement policies, the current blockchain network may determine a preset number of endorsement nodes corresponding to the data transfer hash value from a plurality of endorsement nodes according to the data transfer hash value, and take a majority of the preset number of endorsement nodes corresponding to the data transfer hash value as a target endorsement node.

Optionally, in the step S1015, after determining the target endorsement node, the current blockchain network may send the current data transfer request to the target endorsement node, so as to forward the current data transfer request sent by the client to the target endorsement node.

In the embodiment of the application, the target endorsement node for executing the intelligent contract is determined through the endorsement strategy and the data transfer hash value corresponding to the current data transfer request, so that the determination precision of the target endorsement node can be improved, and the data transfer precision is improved.

S103, the target endorsement node responds to the current data transfer request and executes an intelligent contract corresponding to the current data transfer request to obtain a current contract execution result; the current contract execution result includes a current data transfer read-write set.

Optionally, since the current data transfer request carries the called smart contract, the target endorsement node may execute the smart contract carried by the current data transfer request when receiving the current data transfer request. Wherein, the endorsement node performs intelligent contracts can be understood as: the endorsement node registers its own public key and other business related information into the intelligent contract, and the process of registering information into the intelligent contract by the endorsement node can be understood as the endorsement node executing the intelligent contract. Illustratively, some of the other business related information described above may include, but is not limited to: certificate information, port information, international interconnection protocol (Internet Protocol, IP), etc. Since the number of endorsement nodes may be plural, a plurality of endorsement nodes are registered in the intelligent contract, an endorsement node list may be formed in the intelligent contract, and an endorsement signature in the endorsement node list is valid, and if a certain endorsement node is not registered in the intelligent contract, i.e., does not exist in the endorsement node list, the endorsement signature of the endorsement node is invalid.

In one embodiment, the registration mode of the endorsement node may be an organization registration mode, and an endorsement node list corresponding to an organization may be queried through an endorsement node contract. For example, a blockchain network is jointly created by N enterprises, where N is a positive integer greater than or equal to 1, and the N enterprises are N organizations, which may represent N nodes in the blockchain network, and each organization may register corresponding endorsement nodes, so that the entire blockchain network includes 2N nodes (i.e., N consensus nodes and N endorsement nodes), and each organization corresponds to one consensus node and one endorsement node respectively. Because each organization has corresponding endorsement nodes, the corresponding endorsement node list of a certain organization can be conveniently inquired and obtained through the registration mode according to the organization.

In another embodiment, the registration mode of the endorsement node may be a registration mode according to a contract, and the endorsement node contract may be used to query an endorsement node list corresponding to the contract. For example, there are N intelligent contracts, each intelligent contract can register at least one endorsement node to form an endorsement node list corresponding to each intelligent contract, and the endorsement node list corresponding to a certain intelligent contract can be conveniently queried according to the registering mode of the contract.

Alternatively, continuing with FIG. 4, the current contract execution results may include, but are not limited to: current data transfer read-write set, data transfer event log list, contract return value, etc.

Illustratively, the current data transfer read-write set may characterize data of the target endorsement node for read-write operations, and the current data transfer read-write set may include a read set and a write set. The read set may further include an executed smart contract name, key, data transfer version, etc., and the key in the read set may be a key value pair of a variable read when performing data transfer. The write set may further include a contract name, key value, etc. that is executed, and the key in the write set may be a key value pair of a variable written when performing data transfer. The keys in the read-write set mean exclusive use of corresponding data, for example, in a resource transfer scenario, the read-write set includes an initiator account address and a recipient account address.

Illustratively, the list of data transfer event logs may further include data transfer topics, data transfer logs, and the like.

S105, the target endorsement node transmits the current contract execution result to the consensus node.

Optionally, after the target endorsement node executes the intelligent contract to obtain the current contract execution result, the current contract execution result may be broadcast to the consensus node by a wired or wireless transmission manner.

Specifically, the consensus node is a node present in the blockchain network, which may be determined by a consensus mechanism. The consensus mechanism is to complete verification and confirmation of data transfer operation in a short time through voting of special nodes; for a data transfer operation, if several nodes that are not of interest can agree on it, the entire blockchain network can be considered to agree on it as well.

Alternatively, in the embodiment of the present application, the current contract execution result may be sent to the consensus node in a plurality of manners, which is not specifically limited herein.

In an alternative embodiment, fig. 5 is a flowchart of a second data transfer processing method according to an exemplary embodiment, as shown in fig. 5, where in the step S105, the target endorsement node sends the current contract execution result to a consensus node, and may include:

s1051, the target endorsement node signs the current contract execution result and the current data transfer request to obtain current data transfer information carrying endorsement signature.

S1053, the target endorsement node transmits the current data transfer information to the consensus node.

Alternatively, in the above step S1051, the target endorsement node may attach the current contract execution result to the back of the current data transfer request, and sign the current contract execution result and the current data transfer request to obtain the current data transfer information carrying the endorsement signature.

Optionally, in the step S1053, the number of the target endorsement nodes may be plural, and one target endorsement node may be selected from the plural target endorsement nodes as the master node, and after the master node collects the endorsement signature satisfying the endorsement policy, the master node may assemble a complete current data transfer operation to be packaged as shown in fig. 4, and broadcast the complete current data transfer operation to the consensus node. As shown in fig. 4, in the case where there are a plurality of endorsement signatures, an endorsement signature list may be formed. For example, in the case of a data transfer into a transaction, the complete current data transfer operation may be considered a current complete transaction.

In the embodiment of the application, the security and the reliability of data transfer can be improved by attaching the current contract execution result to the back of the current data transfer request and signing the current contract execution result and the current data transfer request.

S107, the consensus node performs data transfer conflict detection on the current data transfer read-write set to obtain a current detection result; the current detection result comprises a first current data transfer operation set, wherein the first current data transfer operation set is a set formed by non-conflict data transfer operations.

In an alternative embodiment, the method may further include: after the consensus node receives the current data transfer information carrying the endorsement signature, the consensus node can first verify that the endorsement signature meets an endorsement policy corresponding to the intelligent contract.

In one embodiment, in the case where the endorsement signature does not satisfy the endorsement policy, indicating that the endorsement signature is not legitimate, the consensus node does not perform a data transfer collision detection operation.

In another embodiment, the consensus node places the current data transfer operation into the data transfer pool in the event that the endorsement signature satisfies an endorsement policy. In the proposal block stage, the consensus node acquires a batch of complete current data transfer operation from the data transfer pool and verifies whether a read-write set of the batch of current data transfer operation has conflict data transfer operation. Wherein, the conflict refers to: multiple accounts of the client may concurrently submit multiple data transfer requests for modification to the same data set, and the application processing data is sent to the blockchain network for consensus, and then stored in the ledger, so that conflicting data transfer operations exist in one block.

If there are conflicting data transfer operations, only one of the conflicting data transfer operations (i.e., the non-conflicting data transfer operation) is reserved and the other data transfer operations are marked as stale data transfer operations (i.e., conflicting data transfer operations). Specifically, a set of non-conflicting data transfer operations may be considered a first set of current data transfer operations, and a set of conflicting data transfer operations that conflict with data transfer operations in the first set of current data transfer operations may be considered a second set of current data transfer operations.

For example, the first and second current sets of data transfer operations may be in the form of a list of data transfer operations. Taking data transfer as an example of a transaction, the list of data transfer operations may be a list of transactions.

For example, when the current data transfer read-write set performs data transfer conflict detection, data transfer operations modified for the data set 1 are found to be data transfer operation 1, data transfer operation 2 and data transfer operation 3 respectively, data transfer operations modified for the data set 2 are found to be data transfer operation 4 and data transfer operation 5 respectively, and then for the data set 1, the data transfer operations 1, 2 and 3 conflict, one of the data transfer operations 1, 2 and 3 can be reserved, for example, the data transfer operation 1 is reserved, and the data transfer operation 2 and 3 are marked as conflict data transfer operations conflicting with the data transfer operation 1. For data set 2, data transfer operation 4 and data transfer operation 5 conflict, one of data transfer operations 4 and data transfer operation 5 may be reserved, e.g., data transfer operation 4 is reserved, and data transfer operation 5 is marked as a conflicting data transfer operation that conflicts with data transfer operation 4. Finally, the set of data transfer operations 1 and 4 may be referred to as a first current set of data transfer operations, and the set of data transfer operations 2, 3, and 5 may be referred to as a second current set of data transfer operations.

S109, the consensus node creates a current new block, packages the first current data transfer operation set into the current new block, and transmits the packaged current new block to other nodes in a current block chain network; the other nodes include the target endorsement node.

Optionally, in S109, the consensus node may create a new block, package the first current data transfer operation set into the current new block for proposal, and perform consensus processing on the current new block using a consensus flow in the current new block. After consensus is reached, the consensus node communicates the packaged current new block to other nodes in the current blockchain network to broadcast the new block in the current blockchain network.

In an alternative embodiment, the consensus node may broadcast the current new chunk directly in the blockchain network in the event that there is no read-write collision with the current data transfer read-write set.

In still another alternative embodiment, in the case where there is a read-write collision in the current data transfer read-write set, in S109, the transferring the packaged current new block to another node in the current blockchain network may include:

S1091, under the condition that the current detection result comprises a second current data transfer operation set, the common node attaches the second data transfer operation set to the packaged current new block to obtain a current new block carrying the second data transfer operation set; the second set of current data transfer operations is a set of conflicting data transfer operations, the conflicting data transfer operations being data transfer operations that conflict with data transfer operations in the first set of current data transfer operations.

S1093, the consensus node transmits the current new block carrying the second data transfer operation set to other nodes.

Optionally, in the above steps S1091-S1093, in the case where there is a read-write conflict in the current data transfer read-write set, that is, in the case where the above current detection result includes the second current data transfer operation set, the consensus node may append the conflicting second data transfer operation set on the current new block, obtain the current new block carrying the second data transfer operation set, and broadcast the current new block carrying the second data transfer operation set in the entire blockchain network.

In the embodiment of the application, the first current data transfer operation set formed by the packed non-conflict data transfer operation is packed into the current new block, and the conflict data transfer operation is not packed into the current new block, so that the conflict data transfer operation does not exist in the data structure of the current new block, the hash calculation of the current new block is not influenced, and the problem of marking the failure data transfer operation is not caused because the failure data transfer operation does not exist in the current new block, the occupation of a failure data transfer operation disk is avoided, and the utilization rate of the disk and the performance of a block chain are improved.

In an alternative embodiment, the method may further include:

and the consensus node updates the local data transfer record of the consensus node based on the packaged current new block.

Optionally, while broadcasting the packaged current new block to the blockchain network, the consensus node may further incorporate the packaged current new block into its own local data transfer record, so as to update its own local data transfer record, thereby implementing updating of the local data transfer record of the consensus node. In the case of data transfer into transactions, the data transfer record may be a ledger. Because the packed current new block comprises non-conflict data transfer operation but does not comprise conflict data transfer operation, the updated local data transfer record also does not comprise conflict data transfer operation, occupation of a failure data transfer operation disk is avoided, and the utilization rate of the disk and the performance of a block chain are improved.

S1011, the other nodes update local data transfer records of the other nodes based on the packaged current new block.

Optionally, after receiving the packaged current new block, the other nodes may perform a series of verification, for example, verify whether the block data format is correct, whether the hash value of the block header is less than the target difficulty, whether the block timestamp is within the allowable range, whether the data transfer transaction in the block is valid, and so on, and when all the verification passes, the other nodes may incorporate the new packaged current new block data into their own local data transfer record, so as to update the local data transfer record.

The other node may be, for example, a target endorsement node, where after receiving the packaged current new block, the target endorsement node performs the series of verification as described above, and when the verification passes, the target endorsement node includes the packaged current new block data into its own local data transfer record, so as to implement updating of the local data transfer record.

Continuing with FIG. 5, in an alternative embodiment, the other nodes are target endorsement nodes, and after the consensus node passes the current new block carrying the second set of data transfer operations to the other nodes, the method further comprises:

s201, the target endorsement node extracts a second data transfer operation set from a current new block carrying the second data transfer operation set.

S203, the target endorsement node re-uses the data transfer request corresponding to the second data transfer operation set as the current data transfer request.

S205, the target endorsement node repeats the above-mentioned response to the current data transfer request, executes the intelligent contract corresponding to the current data transfer request, obtains the current contract execution result, and sends the current contract execution result to the operation of the consensus node.

S207, repeating the data transfer conflict detection on the current data transfer read-write set by the consensus node to obtain a current detection result, and transmitting the current new block carrying the second data transfer operation set to the other nodes; and repeating the operation of updating the local data transfer record based on the packaged current new block by the other nodes, and stopping when the current detection result does not comprise the second current data transfer operation set.

Optionally, in the step S201, there is a conflict data transfer operation in the current data transfer read-write set, that is, in the case that the current detection result includes the second current data transfer operation set, the endorsement node may extract the second data transfer operation set of the data transfer conflict from the current new block, in addition to updating the local data transfer record based on the packaged current new block.

Optionally, in the step S203, since the second data transfer operation set is obtained by performing data transfer conflict detection on the current data transfer read-write set by the consensus node, and the current data transfer read-write set is obtained by executing the intelligent contract by the endorsement node in response to a certain data transfer request, it is seen that the second data transfer operation set corresponds to the certain data transfer request, and therefore the data transfer request corresponding to the second data transfer operation set may be extracted and re-used as the current data transfer request.

Optionally, in the step S205, for the target endorsement node, the target endorsement node re-executes the intelligent contract corresponding to the current data transfer request in response to the current data transfer request, to obtain the operation of the current contract execution result including the current data transfer read-write set; and re-executing the operation of transmitting the current contract execution result to the consensus node. For the consensus node, the consensus node re-executes the operation of carrying out data transfer conflict detection on the current data transfer read-write set to obtain a current detection result comprising a first current data transfer operation set; and re-executing the operation of creating the current new block, packaging the first current data transfer operation set into the current new block, and transmitting the packaged current new block to other nodes in the current blockchain network. For other nodes, the other nodes re-execute the operation of updating the local data transfer record of the other nodes based on the packaged current new block. And (3) repeating the cycle until the current detection result does not comprise the second current data transfer operation set, namely stopping when the current data transfer read-write set does not have conflict data transfer operation.

For example, when the data transfer conflict detection is performed on the current data transfer read-write set, it is found that the data transfer operations modified on the data set 1 are respectively the data transfer operation 1, the data transfer operation 2 and the data transfer operation 3, and the data transfer operation 1, the data transfer operation 2 and the data transfer operation 3 conflict, one of the data transfer operations 1, the data transfer operation 2 and the data transfer operation 3 can be reserved, for example, the data transfer operation 1 is reserved, the data transfer operation 2 and the data transfer operation 3 are marked as conflict data transfer operations conflicting with the data transfer operation 1, the data transfer operation 1 is used as a first non-conflict current data transfer operation set, and the data transfer operation 2 and the data transfer operation 3 are used as a second conflict current data transfer operation set.

The common node re-creates a current new block (for example, the current new block is a first new block), packages the data transfer operation 1 into the current new block, transmits the current new block carrying the data transfer operation 2 and the data transfer operation 3 to a target endorsement node, updates an account book based on the data transfer operation 1 after verifying the first new block, re-executes an intelligent contract of the data transfer operation 2 and the data transfer operation 3 to obtain a current contract execution result including a current data transfer read-write set, and re-sends the current contract execution result to the common node, and the common node re-performs data transfer conflict detection on the current data transfer read-write set, finds that the data transfer operation 2 and the data transfer operation 3 conflict, and can put the data transfer operation 2 into a non-conflicting first current data transfer operation set and put the data transfer operation 3 into a conflicting second current data transfer operation set.

The consensus node re-creates a current new block (for example, the current new block is a second new block), packages the data transfer operation 2 into the current new block, transmits the current new block carrying the data transfer operation 3 to the target endorsement node, and after verifying the second new block, the target endorsement node updates the account book based on the data transfer operation 2, and then re-executes the intelligent contract of the data transfer operation 3 to obtain a current contract execution result comprising a current data transfer read-write set, and re-transmits the current contract execution result to the consensus node.

And the consensus node re-detects the data transfer conflict of the current data transfer read-write set, and if the fact that no conflict data transfer operation exists at the moment is found, the current new block is re-created (for example, the current new block is a third new block), the data transfer operation 3 is packed into the current new block, no conflict transaction is added, and the third new block is broadcasted to the network, including the current endorsement node. And after the target endorsement node verifies the third new block, updating the account book based on the data transfer operation 3, and stopping the repeated process without other conflict transactions.

In the embodiment of the application, the execution of the intelligent contract is carried out asynchronously by the endorsement node, the execution of the contract does not affect the block chain production block, the complex time-consuming intelligent contract can be supported, and the performance of the block chain can be improved to a very high level; the read-write conflict detection is carried out during the consensus sequencing, and the conflicting data transfer set is broadcasted to the endorsement node, so that the problem that the client continuously reinitiates the same data transfer request due to the failure of the data transfer mark is avoided, the client only needs to submit the data transfer request once, the information transmission frequency between the client and the node is reduced, and the consumption of system resources of the client and the consumption of network transmission resources are reduced; in addition, because the conflict data transfer operation does not exist in the data structure of the block, namely, no invalidation transaction exists in the block, occupation of a disk of the invalidation data transfer operation is avoided, the utilization rate of the disk is higher, and the performance of the block chain network is further improved.

Continuing with fig. 5, in an alternative embodiment, the other node is the target endorsement node, and the method further includes:

s301, the target endorsement node transmits the packaged current new block to the client.

S303, the client updates the local data transfer record of the client based on the packaged current new block.

Optionally, after receiving the packaged current new block sent by the consensus node, the target endorsement node can also transmit the packaged current new block to the client, and the client receives the packaged current new block and updates its local data transfer record, so that on one hand, the local data transfer record of the client is accurately updated, and on the other hand, the endorsement node does not transmit conflicting data transfer operation to the client, so that the client does not need to reinitiate the same data transfer request, only needs to submit the data transfer request once, and the information transmission frequency between the client and the node is reduced, thereby reducing the consumption of system resources of the client and the consumption of network transmission resources.

It should be noted that the data transfer processing method can be applied to not only the scenario of the alliance chain but also the scenario of the public chain. Where a federation chain refers to members of a particular community and limited third parties, which internally designate a plurality of preselected nodes as billing agents, the generation of each block is determined by all of the preselected nodes in common. A public chain refers to a blockchain that anyone can read, send transactions, and that the transactions can be validated effectively, and that can also participate in the consensus process therein.

The endorsement nodes in the public chain cannot ensure that the endorsement nodes are always online, and the endorsement nodes are in a competitive relationship with the endorsement nodes in the alliance chain. In one embodiment, the high online rate of endorsement nodes and the lack of endorsement can be ensured by adding a guarantee in the endorsement node registration contract, and once the endorsement node is found to be wrongly, the endorsement node will be penalized, thereby improving the security of the blockchain network.

In another embodiment, in public chains, the endorsement policy may select a policy for most nodes to endorse, due to the existence of potentially disliked nodes. The endorsement nodes compete with each other to generate blocks, and a POW or POS mode can be adopted to select effective endorsement node signatures when endorsing. Therefore, while the endorsement node signature is added to the data transfer operation, a piece of endorsement node consensus result information can be added. For example, in the step S1051, the obtained current data transfer information carrying the endorsement signature may be added with a result information that is commonly known by the endorsement node, and when the endorsement signature is verified, the commonly known node may also verify the result information that is commonly known by the endorsement node, and if the endorsement node is verified, it indicates that the endorsement node is not a disqualified node, then the commonly known node may perform a subsequent collision detection operation, and if the endorsement node is not verified, it indicates that the endorsement node is a disqualified node, and then the commonly known node does not perform a subsequent collision detection operation.

In an alternative embodiment, embodiments of the present application further provide a data transfer processing system, which may include: the client, the target endorsement node, the consensus node and other nodes;

and the client is used for sending the current data transfer request to the target endorsement node.

And the other nodes are used for updating local data transfer records of the other nodes based on the packaged current new block.
