Description
Technical Field
The present application relates to the field of internet technologies, and in particular, to an asset transfer method, device, and storage medium.
Background
In a series of parallel chain patent applications applied by the applicant before, a whole set of parallel chain architecture is constructed, in the set of architecture, mutual communication is not needed among all parallel chain nodes, the parallel chain nodes record parallel chain transactions to a main chain through the main chain nodes, all the parallel chain nodes synchronize the parallel chain transactions from the main chain to generate parallel chain blocks, then a plurality of consensus nodes in all the parallel chain nodes respectively generate consensus transactions and send the consensus transactions to the main chain nodes, the main chain nodes perform parallel chain consensus through executing all the consensus transactions and record parallel chain consensus results on the main chain, and then all the parallel chain link points synchronize all the consensus transactions and then perform parallel chain self consensus locally and record the parallel chain self consensus results on the parallel chain.
The above parallel chain architecture has the disadvantages that:
on one hand, all parallel chain transactions must be recorded on the main chain, when the number of parallel chains configured on one main chain is larger, the number of parallel chain transactions required to be recorded on the main chain is larger, so that tps (transaction processing amount per second) of the main chain and each parallel chain is limited by transaction processing capacity of the main chain, cannot be horizontally expanded, and is difficult to meet the requirement of high tps of some services;
on the other hand, when the main chain branches back, the parallel chain will roll back along with the main chain, so that it is difficult for the business side of the parallel chain to quickly obtain the transaction execution result that guarantees the certainty.
In view of the above problems, the applicant has proposed a parallel chain consensus mechanism in another application filed concurrently with the present application, which enables tps of a parallel chain not to be limited by transaction processing capability of a main chain and enables a business party of the parallel chain to quickly obtain a transaction execution result that guarantees certainty.
In the parallel chain consensus mechanism, each node of a parallel chain carries out parallel chain consensus through a consensus protocol without bifurcation, the parallel chain does not need to record each parallel chain transaction to a main chain, only the main chain evidence deposit transaction of each parallel chain block height needs to be recorded to the main chain, and after the parallel chain nodes confirm that the main chain evidence deposit transaction of the latest height is successfully executed on the main chain, the parallel chain evidence deposit transactions of the same height are stored in a local transaction pool, so that the parallel chain consensus of the height can be confirmed.
In the parallel chain consensus mechanism, because the consensus mechanism of the parallel chain is not forked, the parallel chain does not roll back along with the rolling back of the main chain, and after the parallel chain execution transaction succeeds when the assets of the main chain are transferred to the parallel chain, the main chain risks rolling back, for example, a user a transfers some assets on the main chain to the parallel chain (main chain-m 1, parallel chain + m 1), and after the parallel chain execution transaction succeeds, the main chain rolls back, and the original successfully executed transaction fails to be executed after rolling back (main chain-0, parallel chain + m 1), which may cause the user a to obtain an asset due to empty.

Detailed Description
The present application will be described in further detail with reference to the following drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not to be construed as limiting the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that, in the present application, the embodiments and features of the embodiments may be combined with each other without conflict. The present application will be described in detail below with reference to the embodiments with reference to the attached drawings.
Fig. 1 is a flowchart of an asset transfer method according to an embodiment of the present invention.
As shown in fig. 1, in this embodiment, the present invention provides an asset transfer method suitable for a main chain node, where the main chain node stores push addresses registered by a plurality of parallel chain nodes, the parallel chain nodes of a parallel chain perform parallel chain consensus through a consensus protocol that does not branch, and a parallel chain block does not roll back along with the main chain block, the method includes:
s11: after the first asset transfer transaction is successfully executed, whether a first push address registered by a parallel chain node of a first parallel chain is stored locally is searched for:
if yes, go to step S12: storing the first asset transfer transaction into a to-be-pushed list; wherein the first asset transfer transaction is a transaction in which a first user requests to transfer his first asset on the main chain to a first parallel chain; and (c) a second step of,
s13: monitoring whether a first transaction for withdrawal by a first user exists in a first number of backbone blocks after a backbone block to which the first asset transfer transaction belongs:
otherwise, step S14 is executed: pushing the first asset transfer transaction to a first pushing address for broadcasting, packaging and executing by corresponding parallel chain nodes;
if yes, go to step S15: judging whether all the first transactions are executed successfully:
if yes, go to step S14: pushing the first asset transfer transaction to a first pushing address for broadcasting, packaging and executing by corresponding parallel chain nodes;
otherwise, step S16 is executed: monitoring whether the first asset transfer transaction fails to execute after the belonging block rolls back:
otherwise, step S14 is executed: pushing the first asset transfer transaction to a first pushing address for broadcasting, packaging and executing by corresponding parallel chain nodes;
if yes, go to step S17: the first asset transfer transaction is deleted from the to-be-pushed list.
Wherein the first number is the rollback safety depth of the main chain.
The method is exemplified below by the case where the user a has 120 aaa coins in the account of the main chain M and performs asset transfer by sending one asset transfer transaction tx1 for transferring 100 aaa coins on the main chain M to the parallel chain N.
After the user side of the user A generates tx1, the tx1 is sent to the main chain network, the main chain node broadcasts, packages and executes the tx1, and the execution is successful, at this time, the balance of the aaa coin in the account of the main chain M of the user A is 20 (the commission charge is not considered temporarily, for example, the commission charge is configured into other currency types, and the balance of the currency type is not influenced).
In step S11, after tx1 is successfully executed, each main-chain node respectively searches whether a push address registered by a parallel-chain node of the parallel chain N exists locally:
for example, if the main chain node m0 is not found, then m0 does not need to push tx1 to the parallel chain link point;
for another example, the main chain node m1 finds the push addresses addr registered in the parallel chain nodes N1 and N2 of the parallel chain N respectively n1 、addr n2 Then, the main chain node m1 executes step S12 to store tx1 in the to-be-pushed list. Other master link points are similar to m0 or m1 and are not listed.
In step S13, the main chain node m1 monitors whether there is a transaction for withdrawal by the user a in 6 main chain blocks (in this embodiment, the rollback security depth of the main chain is 6, and in further embodiments, different block chain systems may be configured with different rollback security depths) after the main chain block1 to which tx1 belongs:
otherwise, step S14 is executed to push tx1 to addr n1 、addr n2 For parallel chain nodes n1, n2 to broadcast and perform in a packagetx1, adding 100 aaa coins in the account of the user A in the parallel chain N;
if yes, step S15 is executed to determine whether all the monitored transactions (single or multiple transactions may be monitored) of the user a for withdrawing money are successfully executed:
for example, if it is detected that one transaction tx2, tx2 is a transaction for extracting 10 aaa coins, and tx2 is successfully executed, step S14 is also executed;
for another example, if it is monitored that one transaction tx3, tx3 is a transaction for extracting 50 aaa coins, and tx3 fails to be executed, step S16 is executed to monitor whether tx1 fails to be executed after block1 rolls back:
for example, if block1 is not rolled back, step S14 is also executed;
for another example, after block1 rolls back, tx1 is executed again successfully, and step S14 is executed in the same way;
for another example, after block1 rolls back, tx3 is executed successfully first (at this time, the balance of aaa coins in the account of the user a on the main chain M remains only 70), and tx1 is executed unsuccessfully, step S17 is executed, tx1 is deleted from the list to be pushed, and tx1 is not pushed any more.
In the embodiment, a pushing mechanism for pushing the asset transfer transaction successfully executed on the main chain from the main chain node to the parallel chain link point is configured for the parallel chain which is not forked and does not roll back along with the main chain, and a safety mechanism for monitoring whether the asset transfer transaction has the risk of execution failure after rolling back is configured in the pushing mechanism, so that the asset transfer transaction pushed from the main chain node to the parallel chain node does not have the risk of execution failure after rolling back, and the normal operation of cross-chain asset transfer in the main chain-parallel chain system is ensured.
FIG. 2 is a flow chart of a main chain node responding to a query request of a parallel chain node in a preferred embodiment of the method shown in FIG. 1.
As shown in fig. 2, in a preferred embodiment, the method further comprises:
s181: receiving a first query request sent by a first parallel link node; wherein the first query request includes a transaction hash of the second asset transfer transaction;
s183: querying an execution result of the second asset transfer transaction according to the transaction hash;
s185: and returning the execution result to the first parallel chain node for judging whether to broadcast and package the second asset transfer transaction according to the execution result and the height difference between the current block height of the main chain and the block height of the block to which the second asset transfer transaction belongs.
Specifically, for the scheme shown in fig. 1, although the security mechanism configured on the main chain side may ensure that there is no risk of execution failure after rollback of the asset transfer transaction pushed by the main chain node to the parallel chain node, when the main chain node directly pushes the asset transfer transaction to the parallel chain node due to malicious reason such as not complying with the security mechanism, the risk of execution failure after rollback of the transaction on the main chain still exists when the parallel chain node directly broadcasts and packages the asset transfer transaction.
In view of the above problem, in this embodiment, after the parallel link node receives the asset transfer transaction pushed by the main chain node, it is possible to verify whether the main chain node pushing the transaction complies with the security mechanism and whether there is a risk in executing the transaction by querying the execution result of the asset transfer transaction and the height difference between the current block height of the main chain and the block height of the block to which the asset transfer transaction belongs.
For example, after receiving tx1 pushed by the main chain node m1, the parallel chain node n1 generates a query request including hash (tx 1), and sends the query request to the main chain node m5.
The main-chain node m5 performs step S181 of receiving the query request, and,
s183, the main chain node m5 queries the execution result of tx1 according to the hash (tx 1);
s185, the main chain node m5 returns the execution result queried in step S183 to the parallel chain node n1.
After receiving the execution result, the parallel chain node n1 judges whether tx1 is successful, and whether the height difference H-H1 between the current block height H of the main chain and the block height H1 of the block1 to which tx1 belongs is not less than the rollback safety depth of the main chain:
if not, it indicates that the main chain node m1 does not comply with the security mechanism of the scheme shown in fig. 1, and the parallel chain node n1 may choose to discard tx1, or may choose to wait for a period of time and then send a query request to other main chain nodes again;
if yes, it means that the main chain node m1 complies with the security mechanism of the scheme shown in fig. 1, and the parallel chain node n1 may broadcast and perform tx1 in a packet manner, or perform a delay process on tx1 according to the security policy configured by the parallel chain.
The above embodiment further checks and verifies whether the asset transfer transaction has a risk of execution failure after rollback by the parallel chain node after receiving the asset transfer transaction pushed by the main chain node, thereby further avoiding the risk caused by the malicious behavior of the main chain node.

As shown in fig. 3, in the present invention, an asset transfer method applicable to a parallel chain node is further provided, where a current parallel chain node registers a first push address of the current parallel chain node in a first main chain node, each parallel chain node of the current parallel chain performs parallel chain consensus through a consensus protocol that does not diverge, and a parallel chain block does not roll back along with a main chain block, and the method includes:
s21: and receiving a first asset transfer transaction pushed by the first main chain node according to the first push address, broadcasting and packaging to execute the first asset transfer transaction.
The first asset transfer transaction is stored in a to-be-pushed list after being successfully executed by a first main chain node, and whether a plurality of first transactions for withdrawing money of first users exist in a first number of main chain blocks after the main chain block to which the first asset transfer transaction belongs is monitored:
