Background

Transaction requests generated in the blockchain network are generally processed by the block generation nodes in a unified manner and are packaged to form blocks. The block generation nodes are not differentiated when processing the transaction requests, but all process and add to the blocks.

Detailed Description

The embodiments of the present invention will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the embodiments of the invention and that no limitation of the invention is intended. It should be further noted that, for convenience of description, only some structures, not all structures, relating to the embodiments of the present invention are shown in the drawings.

Example one

Fig. 1A is a flowchart of a block chain processing method according to an embodiment of the present invention, which provides a real side chain mode based on a block chain technique for solving the problems that the processing complexity of the transaction requests of the existing block chain system is high and the provided pseudo side chain mode cannot independently process short-term batch transaction requests in the same transaction processing system. The applicable blockchain may be a public chain, a federation chain, or a private chain.

The whole set of block chain processing method is executed by the interaction and cooperation of the main chain block generation node, the side chain block generation node and the node to which the side chain initiator belongs, and independently participates in the operation process of the block chain system to form a block chain consisting of a block main chain and at least one block side chain. For example, referring to fig. 1B, the block chain is composed of a block main chain composed of one block link and two block side chains composed of circle links, and the block side chains can eventually return to the block main chain. It should be noted that the transaction request processing procedure of the block side chain and the transaction request processing procedure of the block main chain are independent from each other, and the side chain block generation node may be a node in the block chain system independent of the main chain block generation node, or may be a main chain block generation node.

The method can be executed by the blockchain processing device provided by the embodiment of the invention, and the device can be realized in a software and/or hardware mode and can be integrated in a computing device bearing the blockchain system nodes. Referring to fig. 1A, the method specifically includes:

and S110, responding to a side chain creation request initiated by a side chain initiator in the block chain system to generate a side chain processing instruction, and transmitting the side chain processing instruction in the block chain system, wherein the side chain processing instruction is used for instructing a side chain block generation node to write a side chain transaction request into a block side chain.

Wherein, the side chain initiator is a party with independent event creation side chain requirement, such as a common platform; independent events refer to batch transaction requests that are unrelated or not related to the transaction requests processed by the main chain under the same transaction processing system. Correspondingly, a side chain corresponds to a processing dataset that is processed independently by multiple transaction requests attributed to independent events. For example, in a blockchain of a platform website, a transaction request occurs for users on the platform to transfer money to each other for transaction, and a transaction request also occurs for the platform to send a reward money to the users. If the platform plans to send the large amount of bonus to the user according to a certain strategy, a transaction request of a large amount of bonus is generated, and the transaction request of the bonus has no necessary relation with the normal transaction request of the user, so the transaction request of the bonus can be used as an independent event. The platform is used as a side chain initiator, and a side chain creation request is sent to the block chain system through the node to which the platform belongs.

The side chain creation request is a request sent to the main chain block generation node by the node to which the side chain initiator belongs when a plurality of transaction requests belonging to independent events need to be processed by the side chain initiator. Optionally, the side chain creation request corresponds to an intelligent contract, which may include: the side chain transaction request processing method comprises the following steps of identifying a node to which a side chain initiator belongs, marking a side chain transaction request, ending conditions of the side chain, a rule algorithm which is merged into a main chain when the side chain is ended, a consensus mechanism for selecting block generation nodes in the side chain, the income amount which needs to be paid to the block generation nodes for executing the side chain transaction request processing and the like. The node identification of the side chain initiator can be an ID, a public key or a private key of the node; the identifier of the side chain transaction request refers to an identifier for uniquely determining a type of transaction request to be processed by the side chain, and may be an identifier of the side chain, or an identifier of a node to which the side chain initiator belongs. Specifically, the side-chain transaction request in the block side-chain can be determined according to the identifier of the side-chain transaction request.

The side chain processing instruction is generated by the main chain block generation node according to a side chain creation request initiated by a side chain initiator and used for instructing the side chain block generation node to write a side chain transaction request into a block side chain.

The side-chain transaction request is a transaction request independent from the main-chain transaction request, and optionally, the side-chain transaction request may be a transaction request initiated by a side-chain initiator; or a transaction request with a sidechain attribute included in the sidechain creation request; the attribute of the side chain is used to indicate the transaction to be processed by the side chain, and may be a flag of the side chain, such as ID or name. Illustratively, different sidechain attributes correspond to different sidechain transaction requests; the transaction requests handled by different sidechains differ.

It should be noted that, in this embodiment, the interaction between the side chain initiator and the main chain block generation node is realized by the interaction between the node to which the side chain initiator belongs and the main chain block generation node, and the nodes to which different side chain initiators belong are different. The creation of the sidechain can be performed at any time, and therefore the creation of the sidechain can be initiated by any node having the requirement of creating the sidechain; and a plurality of side chains can be established at the same time in the block chain system, namely, a plurality of nodes can initiate the establishment of different side chains at the same time.

Optionally, in order to ensure that each side chain can be performed in order to improve the efficiency of the whole block chain system, before each side chain block generation node writes a side chain transaction request into a block side chain, it is first determined whether the received transaction request is a transaction request with a side chain attribute included in a corresponding side chain creation request, or a transaction request sent by a node to which a side chain initiator included in the side chain creation request belongs; if any one of the conditions is satisfied, the transaction request is determined to be the side-chain transaction request, and the side-chain transaction request is written into the block side chain.

Specifically, after a main chain block generation node receives a side chain creation request sent by a side chain initiator in a block chain system through a node to which the side chain initiator belongs, the side chain creation request is verified according to a side chain creation consensus stored in the block chain system; if the side chain creation rule is met, generating a side chain processing instruction according to a side chain creation request initiated by a side chain initiator, and transmitting the side chain processing instruction to a block chain system so that a side chain block generation node executes creation of a side chain according to the side chain creation rule; and meanwhile, the side chain processing instruction is used as a transaction request to be processed and written into the current block, so that the position of the side chain can be quickly found in the subsequent query.

S120, in response to the side chain merging request transmitted by the side chain block generation node, writing the transaction data of the tail block in the side chain block into the main chain block.

The side chain merging request is a merging request sent by the side chain block generation node to the main chain block generation node when the side chain transaction request processing is completed, and is used for indicating the main chain block generation node to merge the side chain to the main chain according to the merging rule of the side chain and the main chain. Optionally, the side-chain merge request may include: side chain identification and side chain tail block data, etc.

For example, writing the transaction data of the tail block in the side chain of the block into the main chain of the block may include: and writing the transaction data of the tail block in the block side chain into the main chain of the block by adopting a side chain merging algorithm included in the side chain creating request. The side chain merging algorithm is a rule that a side chain is merged into a main chain in advance. Specifically, after the main chain block generation node receives the merge request sent by the side chain block generation node, the transaction data in the side chain end block included in the merge request is processed as the transaction request, and new transaction data is formed and written into the main chain of the block.

If the side-chain block generation node is the main-chain block generation node, the processed side-chain tail block data can be directly written into the main-chain block, and the side-chain tail block data does not need to be processed, so that the processing efficiency can be improved.

In addition, if there is only one block in the side chain of the block, the side chain corresponds to a processing data set in which a plurality of transaction requests belonging to independent events are subjected to secondary processing, and the processing efficiency is not different. Thus, illustratively, at least two blocks should be included in the block side chain.

It is emphasized that since the processing of the side chain blocks is parallel to the processing of the main chain blocks, the side chain blocks are merged to the main chain from the beginning to the end, and the number of the generated side chain blocks is the same as the number of the blocks of the main chain in the whole time period, for example, as shown in fig. 1B.

For example, generating a sidechain processing instruction in response to a sidechain creation request initiated by a sidechain initiator in the blockchain system may include: responding to a side chain creation request initiated by any party in the block chain system, deducting the freezing proof of the party, writing a deducting result into a block main chain, taking the party as a side chain initiator, and generating a side chain processing instruction initiated by the side chain initiator.

The freeze proof may be a digital currency or Token, which may be used to circulate through the blockchain system, and a means for awarding or penalizing nodes in the blockchain system.

Specifically, after the main chain block generation node receives a side chain creation request initiated by any initiator in the block chain system, the corresponding freezing proof of the side chain initiator is deducted according to the income amount which is provided in the side chain creation request and needs to be paid to the block generation node executing the side chain transaction request processing, and the deduction result is written into the main chain block as the transaction request to be used as the basis for subsequent inquiry or proof. Meanwhile, the main chain block generation node takes the side chain creation request as a side chain initiator, and generates a corresponding side chain processing instruction according to the side chain creation request transmitted by the side chain initiator.

To facilitate the side chain initiator to query the deduction result, the example that the main chain block generating node writes the deduction result of the side chain initiator into the main chain of the block may further include: the block address at which the deduction result is stored in the block main chain is fed back to the side chain initiator.

For example, after the main chain block generation node writes the deduction result of the side chain initiator into the main chain of the block, the method may further include: if the freezing proof provided by the side chain initiator is not deducted, the main chain block generation node feeds back the residual freezing proof and deduction result to the side chain initiator.

Example two

Fig. 2 is a flowchart of a block chain processing method according to a second embodiment of the present invention, in which a main chain block generating node, a side chain block generating node, and a side chain initiator belong to nodes that are executed in an interactive manner. The scheme of the embodiment of the present invention is applied to a side-chain block generation node in a block chain system, and the method may be executed by the block chain processing apparatus provided in the embodiment of the present invention, and the apparatus may be implemented in a software and/or hardware manner, and may be integrated in a computing device carrying the block chain system node. Referring to fig. 2, the method specifically includes:

s210, writing the processing data of the side-chain transaction request into the side chain of the block according to the side-chain processing command transmitted from the main-chain block generating node in the block chain system.

The side chain processing instruction is generated according to a side chain creation request initiated by a side chain initiator in the block chain system.

Specifically, after the side-chain block generating node receives the side-chain processing instruction transmitted by the main-chain block generating node, the side-chain transaction request is determined and acquired according to the side-chain processing instruction, the side-chain transaction request is subjected to processing such as information conversion, format adjustment or code running, and the processed data is stored in the block side chain.

Because a plurality of side chains can be established at the same time, in order to ensure that each side chain can be performed in order to improve the efficiency of the whole block chain system, before each side chain block generation node writes a side chain transaction request into a block side chain, it is necessary to determine whether the transaction request received by itself is a transaction to be processed by the side chain.

Before writing the processing data of the side-chain transaction request into the block side chain, the exemplary method may further include: determining a transaction request initiated by a side chain initiator as a side chain transaction request; alternatively, a transaction request having a sidechain attribute included in the sidechain creation request is determined as a sidechain transaction request.

Specifically, the side-chain block generating node may determine, according to a side-chain attribute included in the received side-chain creation request, a transaction request that satisfies the side-chain attribute in the received transaction requests as a side-chain transaction request, and discard the side-chain transaction request unsatisfied with the side-chain attribute; or screening and determining the side chain transaction request from the received transaction requests according to the identification of the node to which the side chain initiator initiating the side chain creation request belongs.

For example, before writing the processing data of the side-chain transaction request into the side-chain of the block, the side-chain block generating node may further include: the side chain block generation right is obtained from a node responding to the side chain creation request in the block chain system based on a side chain consensus mechanism included in the side chain creation request.

The consensus mechanism is an important component of the blockchain technology, and functions to enable a plurality of nodes in the blockchain system to achieve consensus on a certain target, for example, the nodes with block generation rights can be determined based on the consensus mechanism, and an intelligent contract can be achieved.

Illustratively, the side chains may employ a different consensus mechanism than the backbone. Because the side chain benefit is constructed and the self comprehensive factors of each node are caused, the nodes responding to the side chain processing instruction are not fixed and the number of the nodes is not fixed, if only one node responding to the side chain establishing request is provided, the node is determined as the side chain block generating node; if the number of the nodes responding to the side chain creation request is multiple, the side chain block generation node can be selected according to comprehensive scores of computing power, hardware capability, false probability, stability, economic strength and the like of each node.

Specifically, after receiving a side chain processing instruction transmitted by a main chain block generation node, a node in the block chain system gives a response according to the actual situation of the node and transmits the response to other nodes, and the nodes giving the response compete with each other for side chain block generation right according to a side chain consensus mechanism included in a side chain request; and the node for obtaining the side chain block generation right is used as the side chain block generation node to process the side chain transaction request to obtain corresponding transaction data, and the data is written into the block side chain.

It should be noted that creating a side chain is equivalent to providing a service for a certain node, so that a node to which a side chain initiator initiating a side chain creation request belongs needs to pay a certain service fee for a side chain block generation node, so as to stimulate other nodes to willfully provide the service, thereby forming a better virtuous circle.

For example, after writing the processing data of the side-chain transaction request into the block side chain, the method may further include: and obtaining block generation income paid by the side chain initiator according to a settlement algorithm included in the side chain creation request.

The settlement algorithm is an algorithm for the side chain initiator to pay the profit amount of the side chain block generation node to create the side chain, and can be determined according to the difficulty degree and the quantity of the side chain transaction requests, the number of blocks included in the side chain and the like. Specifically, after the side chain block generation node writes the processing data of the side chain transaction request into the block side chain, the block generation benefit paid by the side chain initiator can be obtained according to the settlement algorithm included in the side chain creation request.

S220, if the end of the side chain event is detected, a node-transport block side chain merge request is generated to the main chain block.

Wherein the block side chain merge request is used for instructing the main chain block generation node to write the transaction data of the tail block in the block side chain into the block main chain. A sidechain event refers to an event that processes a sidechain transaction request to create a sidechain. And the end of the side chain event is the completion of the side chain transaction request processing.

Specifically, in order to avoid discarding the side chain as a branch chain in the block chain system, the side chain block generation node may detect whether the current state of the side chain reaches an end condition in real time according to the side chain end condition included in the side chain creation request, and if so, generate a block side chain merge request according to the side chain identifier, the side chain tail block data, and the like, and send the block side chain merge request to the main chain block generation node, so that the main chain block generation node processes the transaction data in the side chain tail block included in the merge request as a transaction request according to a merge rule of the side chain and the main chain, so as to form new transaction data to be written into the main chain of the block, that is, the final processing result of the side chain. And the creation process of the side chain is independent from the main chain, so that the interference of the transaction request repeatedly processed in the middle on the main chain transaction request processing is avoided.

Illustratively, detecting whether the side chain event is over may include: if the height of the tail block in the block side chain is detected to be the height of the end block included in the side chain creation request, or if the transaction data of the tail block is detected to meet the end condition included in the side chain creation request, determining that the side chain event is ended.

The block height is a flag of the block, and may be an id or a number of the block. The ending condition is a condition for determining that the transaction request processing in the side chain is completed, and for example, whether the ending condition is reached may be determined according to the number of bytes of the tail block data, a flag of a last transaction request in the tail block data, or an offset amount in a block.

Specifically, if the number of the tail block in the block side chain is equal to the number of the end block included in the side chain creation request, it is determined that the side chain time is ended; or if the byte number or the mark of the transaction data of the tail block is the same as the byte number or the mark of the end block included in the side chain creation request, determining that the side chain time is ended. The end of the side chain event may be determined by checking whether the flag of the last transaction request in the tail block data is the same as the flag of the last transaction request in the end block included in the side chain creation request, or by checking whether the position of the last transaction request in the tail block data is the same as the position of the last transaction request in the end block included in the side chain creation request.

And after determining that the side chain event is finished, the side chain block generation node sends a side chain merging request to the main chain block generation node so that the main chain block generation node merges the side chain to the main chain according to the merging rule of the side chain and the main chain.

According to the technical scheme provided by the embodiment of the invention, the side chain block generation node writes the processing data of the side chain transaction request into the side chain of the block according to the side chain processing instruction sent by the main chain block generation node, and transmits the block side chain merging request to the main chain block generation node when the end of the side chain event is detected, so that the main chain block generation node writes the transaction data of the tail block in the block side chain into the main chain of the block. The method can process irrelevant and batched transaction requests independently to form the block main chain and the block side chain, and the block side chain can return to the block main chain finally, so that the processing complexity of the transaction requests in different batches is simplified, and the efficiency of the whole block chain system for processing the transaction requests is improved.

EXAMPLE III

Fig. 3 is a flowchart of a block chain processing method according to a third embodiment of the present invention, in which a main chain block generating node, a side chain block generating node, and a side chain initiator belong to nodes that are executed in an interactive manner. The method can be executed by the block chain processing device provided by the embodiment of the invention, and the device can be realized in a software and/or hardware mode and can be integrated in a computing device bearing the block chain system node. Referring to fig. 3, the method specifically includes:

s310, initiate a side chain creation request.

The side chain creation request refers to a request sent to the main chain block generation node by a node to which the side chain initiator belongs when a plurality of transaction requests belonging to independent events need to be processed by the side chain initiator. Optionally, the side chain creation request corresponds to an intelligent contract, which may include: the side chain transaction request processing method comprises the following steps of identifying a node to which a side chain initiator belongs, marking a side chain transaction request, ending conditions of the side chain, a rule algorithm which is merged into a main chain when the side chain is ended, a consensus mechanism for selecting block generation nodes in the side chain, the income amount which needs to be paid to the block generation nodes for executing the side chain transaction request processing and the like.

Thus, optionally, initiating the sidechain creation request may comprise:

(1) and determining the side chain attribute to enable the side chain block generation node to determine the transaction request with the side chain attribute as the side chain transaction request.

The attribute of the side chain is used to indicate the transaction to be processed by the side chain, and may be a flag of the side chain, such as ID or name. Illustratively, different sidechain attributes correspond to different sidechain transaction requests; the transaction requests handled by different sidechains differ.

Specifically, since the blockchain system can have multiple side chains established at the same time, in order to ensure that each side chain can be performed in order to improve the efficiency of the whole blockchain system, the side chain initiator needs to explicitly specify the transaction request to be processed by the established side chain in initiating the side chain establishment request.

(2) And determining a side chain consensus mechanism, so that the side chain block generation node obtains the side chain block generation right from the node responding to the side chain creation request in the block chain system based on the side chain consensus mechanism.

It should be noted that the side chain consensus mechanism may adopt a different consensus mechanism from the main chain, and different side chains may adopt different consensus mechanisms, or the same consensus mechanism may be adopted. Since creating a side chain is equivalent to providing a service for a certain node, a node to which a side chain initiator initiating a side chain creation request belongs needs to pay a certain service fee for a side chain block generation node. For example, based on the reasons for constructing the side chain profit and the self comprehensive factors of each node, if only one node responds to the side chain creation request, the node which intentionally generates the side chain may be determined as the block generation node; if the number of the nodes responding to the side chain creation request is multiple, the side chain block can be selected to generate the node according to comprehensive grading competition of computing power, hardware capability, false probability, stability, economic strength and the like of each node.

Specifically, because the construction of the side chain involves the problem of revenue, the side chain initiator needs to specify how to select a side chain block generation node, i.e., a consensus mechanism, from nodes responding to the side chain creation request in the block chain system in the side chain creation request, so that each responding node competes for the side chain block generation right based on the pre-agreed consensus mechanism.

(3) And determining a settlement algorithm, so that the side chain block generation node obtains the block generation income paid by the side chain initiator according to the settlement algorithm included in the side chain creation request.
