Detailed Description
In order to make the objects, technical solutions and advantages of the present disclosure more clear, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step based on the embodiments in this description belong to the protection scope of this document.
Based on the statement in the background section, the transaction of the user may be replayed on other chains because the transaction does not carry the certification of the trusted environment identified by the user when the user executes the transaction, and further, the user information is leaked. Based on this, the present specification provides a blockchain transaction processing method, which introduces a concept of anchor data of a blockchain, and anchors a transaction to a blockchain to which the transaction belongs in a manner of adding the anchor data in the transaction, so that when a client sends a transaction request to a blockchain platform, the blockchain platform can decide whether to execute the transaction in the transaction request by verifying the matching between the anchor data carried by the transaction in the transaction request and the anchor data of the blockchain platform, thereby avoiding the problem of transaction replay.
The following exemplifies an application scenario of the present solution:
in connection with fig. 1, in an example of an application scenario, it includes: block chain, block chain platform and client, wherein:
the blockchain platform is a service platform constructed based on a blockchain architecture and used as an interface of blockchain related services, such as various light wallets; the client is a product that can be really and directly used by ordinary people, and corresponds to the block chain related services that can be provided by the block chain platform, such as various light wallet clients. Based on the interaction between the client and the block chain platform, the block chain technology can quickly enter the application field to serve the public.
As shown in fig. 1, the client corresponding to the blockchain platform may be supported to be installed on a mobile terminal or a PC, and the mobile terminal or called mobile communication terminal refers to a computer device that can be used in mobile, and broadly includes a mobile phone, a notebook, a tablet computer, a POS machine, and even includes a vehicle-mounted computer.
The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.
Fig. 2 is a flowchart of a blockchain transaction processing method provided in an embodiment of the present disclosure, which can be executed by the blockchain platform in fig. 1, with reference to fig. 2, where the method specifically includes the following steps:
202, a blockchain platform receives a transaction request sent by a first client, wherein the transaction request carries first anchoring data, and the first anchoring data is used for anchoring a transaction in the transaction request to a blockchain to which the transaction belongs;
the blockchain to which the transaction belongs refers to a blockchain accessed by all nodes participating in the transaction, for example, for the transactions participated by the nodes a and b, the transaction belongs to the blockchain accessed by the nodes a and b together.
In combination with the statements in the background section, since there may be a situation that a transaction initiated on one chain may be rebroadcast to another chain, and may also be confirmed, before a client initiates a transaction request to a blockchain platform, it is necessary to first obtain anchor data of a blockchain to which the transaction belongs from the blockchain platform, and anchor the transaction to the blockchain to which the transaction belongs according to the anchor data, thereby ensuring that the transaction is executed in a trusted environment corresponding to the blockchain to which the transaction belongs.
The following describes the transaction anchoring process in detail by taking a scenario of block chain forking as an example:
two branched chains of the block chain are respectively a first block chain and a second block chain, wherein the block chain which is accessed by the target transaction party together including the node a and the node b is the first block chain.
When a client submits a target transaction, firstly, the anchoring data of a first block chain is inquired from a block chain platform constructed based on the first block chain, and the anchoring data of the first block chain is set in the target transaction, so that the target transaction is anchored to the first block chain.
Step 204, acquiring second anchor data corresponding to the block chain of the block chain platform;
the blockchain of the blockchain platform refers to the blockchain according to which the blockchain platform shown in fig. 1 is constructed, and the blockchain may be the same as or different from the blockchain to which the transaction belongs.
The implementation of step 204 is described in detail below:
s1, calling an intelligent contract on the blockchain of the blockchain platform to acquire an anchor type, wherein the intelligent contract is used for configuring the anchor type of the blockchain, and the anchor type is used for indicating an anchor object of the transaction in the blockchain; the intelligent contracts can be configured in the creation blocks of the blockchain platform through background management by an administrator of the blockchain platform.
And S2, generating second anchor data based on the anchor object corresponding to the anchor type.
For the anchor objects, it should be noted that the anchor objects are of many kinds, and are not exhaustive, as long as the anchor objects can uniquely identify the block chain and are different from the same type of parameters of other block chains. Specific examples can be:
example 1, the anchor types include: node anchoring;
one implementation of S2 may be:
determining a node list of a blockchain of the blockchain platform; and carrying out hash processing on the node list to obtain second anchor data. Wherein the node list may include all nodes of the blockchain currently.
Example 2, the anchor types include: anchoring the block;
another implementation of S2 may be:
determining a target block in a block chain of the block chain platform, wherein the target block is an anchor object indicated by the anchor type; and obtaining second anchor data based on the hash value of the target block.
Preferably, the target block is an established block of a block chain of the block chain platform.
Of course, it is understood that the anchor type may also be a combination of the two examples, or other objects of the block chain, such as a timestamp, may also be introduced, and the other objects may be used as anchor objects or combined with node anchors and block anchors as anchor objects, which is not limited herein.
On the basis, on one hand, the method avoids leakage of the anchor type by writing the anchor type into the intelligent contract, so that the security of the anchor data is ensured; on the other hand, the concept of node anchoring/block anchoring is introduced, and the transaction is anchored to the block chain according to the node/block related data of the block chain, so that the certification of the trusted environment of transaction confirmation is definitely performed. Furthermore, the embodiment of the present specification shows a specific implementation manner of the foregoing pre-block hash. Of course, it should be understood that the preceding block hash may also be implemented in other ways, and this is not limited by the embodiment of the present application.
In addition, in order to further avoid the leakage of the anchor type and improve the proof effectiveness of the trusted environment identified when the transaction is executed, the embodiment further proposes a maintenance scheme of the anchor type, which includes the following steps:
s1' receives an execution completion event that modifies the anchor type transaction;
s2' responds to the execution completion event, and calls the intelligent contract to acquire the modified anchor type.
The transaction to modify the anchor type is typically initiated by an administrator when the anchor rules need to be maintained, such as when the node anchor needs to be modified to a node + timestamp anchor type, the administrator needs to initiate a transaction request to maintain the previously submitted intelligent contract configuring the node anchor. When the transaction request passes through the consensus of the blockchain platform and the execution of the transaction of the modified anchor type is completed, the blockchain platform responds to the event of the execution completion and calls the latest intelligent contract to perform the synchronization of the modified anchor type.
In connection with step 204, the following introduces a second client and explains the transaction anchoring process again from the perspective of the second client anchoring the transaction to the blockchain platform:
firstly, a second client initiates a query request to a block chain platform; responding to the query request sent by the second client, and generating anchor data of the block chain platform according to the latest anchor type and recording the anchor data as second anchor data by the block chain platform according to the step 204 and the related content; returning the second anchoring data in response to a query request sent by a second client; the second client initiates a transaction request after setting the second anchor data in a transaction, thereby anchoring the transaction to a blockchain of a blockchain platform.
The second client and the first client may be the same client or different clients.
And step 206, if the second anchor data is matched with the first anchor data, performing submission operation of the transaction in the transaction request in the blockchain of the blockchain platform.
And if the first anchor data and the second anchor data do not match, refusing to execute the submission operation of the transaction in the transaction request in the blockchain of the blockchain platform.
It should be understood that if the second anchor data matches the first anchor data, it indicates that the blockchain of the transaction anchor and the blockchain of the blockchain platform are the same blockchain, i.e. the transaction can be executed in the blockchain of the blockchain platform; and if the first anchor data and the second anchor data are not matched, the block chain of the transaction anchor is not the block chain of the block chain platform, but other block chains, and the block chain platform refuses the transaction to be executed in the block chain of the block chain platform.
Therefore, in the embodiment, the transaction is anchored to the block chain to which the transaction belongs in a manner of adding the anchor data in the transaction, so that when the client sends the transaction request to the block chain platform, the block chain platform can decide whether to execute the transaction in the transaction request by verifying the matching between the anchor data carried in the transaction and the anchor data of the block chain platform, thereby avoiding the problem of transaction replay and further ensuring the security of user information.
Fig. 3 is a flowchart illustrating a blockchain transaction processing method according to another embodiment of the present disclosure, which may be executed by the client in fig. 1, referring to fig. 3, where the method may specifically include the following steps:
step 302, the client sends a query request to the blockchain platform;
step 304, receiving first anchor data returned by the blockchain platform in response to the query request, wherein the first anchor data is used for anchoring a transaction to a blockchain of the blockchain platform by the client;
specifically, the method comprises the following steps: and the block chain platform responds to the query request to acquire and return pre-generated first anchor data, wherein the first anchor data are generated by the block chain platform based on the anchor type configured in the intelligent contract. The specific generation scheme has been described in detail in the embodiment corresponding to fig. 2, and therefore, the detailed description is omitted here.
Step 306, sending a transaction request to the blockchain platform, wherein the request of the transaction request carries the first anchor data.
Specifically, the method comprises the following steps: before step 306 is executed, a step of setting first anchor data in the transaction is further included, and specifically, the first anchor data may be written in an extension field of the transaction. Therefore, different anchor data are added in the transaction extension field, the transaction can be executed only under a certain trusted environment, and the problems of information leakage and the like caused by the replay behavior of the transaction are prevented.
Further, the first anchor data carried in the request of the transaction request is matched with the anchor data corresponding to the blockchain of the blockchain platform by the blockchain platform, and if the first anchor data and the anchor data are matched, the submission operation of the transaction in the transaction request is executed in the blockchain of the blockchain platform.
In addition, it is understood that if the client sends the transaction request to another blockchain platform, the other blockchain platform also matches the first anchor data carried in the transaction request with the anchor data corresponding to the blockchain of the other blockchain platform, and since the anchor data of the blockchain platform are different, the matching cannot be successful, and thus the submission operation of the transaction in the transaction request cannot be executed in the blockchain of the other blockchain platform.
Therefore, in the embodiment, the transaction is anchored to the block chain to which the transaction belongs by adding the anchor data in the transaction, so that when the client sends the transaction request to the block chain platform, the block chain platform can decide whether to execute the transaction in the transaction request by verifying the matching between the anchor data carried in the transaction and the anchor data of the block chain platform, thereby avoiding the problem of transaction replay and further ensuring the security of user information.

step 402, setting an anchoring type;
specifically, the method comprises the following steps: the administrator sets the anchor type in the created blocks in the form of smart contracts.
Step 404, generating a creating block;
step 406, inquiring the anchoring type;
step 408, returning the anchor type;
specifically, the method comprises the following steps: and generating a founding block and starting a system platform, wherein the block chain platform inquires the anchoring type from the system contract.
Step 410, generating anchoring data based on the anchoring type;
specifically, the method comprises the following steps: if the anchoring type is the type of node anchoring, inquiring an id list of a recognition node in the current node environment; and carrying out hash on the node list to generate anchor data.
And if the anchor type is a block anchor type, taking the hash of the created block as anchor data.
Step 412, inquiring anchoring data;
specifically, the method comprises the following steps: client sdk starts by first querying the blockchain for the current anchor data.
Step 414, setting anchor data in the transaction;
step 416, sending a transaction request;
specifically, the method comprises the following steps: sdk places the anchor information in the extension field of the transaction and sends it to the platform (blockchain platform).
Step 418, whether the anchor data in the transaction is matched with the anchor data in the current system;
if yes, executing the transaction in a block chain of the block chain platform; otherwise, transaction failure is returned.
Therefore, in the embodiment, the transaction is anchored to the block chain to which the transaction belongs in a manner of adding the anchor data in the transaction, so that when the client sends the transaction request to the block chain platform, the block chain platform can decide whether to execute the transaction in the transaction request by verifying the matching between the anchor data carried in the transaction and the anchor data of the block chain platform, thereby avoiding the problem of transaction replay and further ensuring the security of user information.
