The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.
[0054] Figure 1 A flowchart of an asset transfer method provided by an embodiment of the present invention. Figure 1 As shown, in this embodiment, the present invention provides an asset transfer method applicable to a client, the method comprising:
[0055] S12: In response to the current user transferring assets held on a number of first parallel chains to a number of second parallel chains, a first asset transfer transaction is generated; wherein the first asset transfer transaction includes a first identifier of each first parallel chain and each second parallel chain, and each first transaction content executed on each first parallel chain and each second parallel chain respectively;
[0056] S14: Send the first asset transfer transaction to the main chain for each parachain node of each parachain to:
[0057] Determine whether the first identifier in the first asset transfer transaction includes the second identifier of the corresponding parallel chain:
[0058] If yes, the corresponding first transaction content is executed:
[0059] If the corresponding first transaction content is to deduct certain assets, then freeze certain assets;
[0060] If the corresponding first transaction content is to generate a number of assets, then generate a number of assets and freeze the generated assets; and,
[0061] Generate a consensus transaction of the parachain block including the first asset transfer transaction and send it to the main chain;
[0062] S16: When all the parachain blocks including the first asset transfer transaction have successfully reached consensus on the main chain, a first confirmation transaction including the transaction hash of the first asset transfer transaction is generated and sent to the main chain for each parachain node of each parachain to:
[0063] Determine whether the first asset transfer transaction is included on the parallel chain based on the transaction hash:
[0064] If yes, execute the first confirmation transaction: obtain the execution result of the first asset transfer transaction that succeeded in each consensus from the main chain;
[0065] Determine whether all execution results are successful:
[0066] If yes, the frozen assets will be deducted, or the frozen assets generated will be unfrozen;
[0067] If not, the frozen assets will be unfrozen, or the frozen assets generated will be deducted.
[0068] Specifically, assume that there is a main chain mainchain and ten parallel chains parachain1 to parachain10 (whose names are pc1 to pc10) in the blockchain network; take the identifier (including the first identifier and the second identifier) as the name of the parallel chain, and user A wants to transfer the 10 coins held on parachain1 to parachain3, and the 20 coins held on parachain2 to parachain4 as an example;
[0069] User A's client executes step S12. In response to user A's intention to transfer the 10 coins held on parachain1 to parachain3 and the 20 coins held on parachain2 to parachain4, an asset transfer transaction tx1 is generated. tx1 includes pc1, pc2, pc3, pc4, and the transaction content (account(A)_pc1, -10coin) executed by each parachain node of parachain1, the transaction content (account(A)_pc2, -20coin) executed by each parachain node of parachain2, the transaction content (account(A)_pc3, +10coin) executed by each parachain node of parachain3, and the transaction content (account(A)_pc4, +20coin) executed by each parachain node of parachain4.
[0070] User A's client executes step S14 and sends tx1 to the main chain;
[0071] The main chain node stores tx1; in more embodiments, the main chain node may also execute tx1, and record the first identifier and each first transaction content on the main chain (that is, record pc1, pc2, pc3, pc4, and (account(A)_pc1, -10coin), (account(A)_pc2, -20coin), (accoun t(A)_pc3, +10coin), (account(A)_pc4, +20coin) on the main chain);
[0072] Each parachain node of parachain1 to parachain10 determines whether the identifiers pc1, pc2, pc3, and pc4 in tx1 include the identifier of the parachain to which they belong:
[0073] tx1 includes pc1, then each parachain node of parachain1 executes (account(A)_pc1,-10coin) to freeze 10coin of account(A) on parachain1;
[0074] If tx1 includes pc2, each parachain node of parachain2 executes (account(A)_pc2,-20coin) to freeze 20coin of account(A) on parachain2.
[0075] If tx1 includes pc3, each parachain node of parachain3 executes (account(A)_pc3,+10coin), generates 10coin in account(A) on parachain3, and freezes the generated 10coin;
[0076] If tx1 includes pc4, each parachain node of parachain4 executes (account(A)_pc4,+20coin), generates 20coin in account(A) on parachain4, and freezes the generated 20coin;
[0077] If tx1 does not include pc5~pc10, the parachain nodes of parachain5~parachain10 will not execute tx1;
[0078] User A's client executes step S16. When all the parallel chain blocks including tx1 have reached consensus successfully on the main chain, a confirmation transaction tx2 including hash(tx1) is generated and sent to the main chain.
[0079] The main chain node stores tx2; in more embodiments, the main chain node can also execute tx2 and record hash (tx1) on the main chain;
[0080] Each parachain node from parachain1 to parachain10 determines whether tx1 is included in the parachain to which it belongs based on hash(tx1):
[0081] Since parachain1 to parachain4 include tx1, each parallel chain node of parachain1 to parac hain4 executes tx2: obtain the execution results of each consensus-successful tx1 from the main chain;
[0082] If all execution results are successful, each parachain node on parachain1 will deduct the 10 coins frozen in account(A) on parachain1; each parachain node on parachain2 will deduct the 20 coins frozen in account(A) on parachain2; each parachain node on parachain3 will unfreeze the 10 coins generated by freezing in account(A) on parachain3, that is, at this time, there are 10 coins in account(A) on parachain3; each parachain node on parachain4 will unfreeze the 20 coins generated by freezing in account(A) on parachain4, that is, at this time, there are 20 coins in account(A) on parachain4;
[0083] If the execution results are not all successful, each parachain node on parachain1 will unfreeze the 10 coins frozen in account(A) on parachain1; each parachain node on parachain2 will unfreeze the 20 coins frozen in account(A) on parachain2; each parachain node on parachain3 will deduct the 10 coins frozen in account(A) on parachain3; each parachain node on parachain4 will deduct the 20 coins frozen in account(A) on parachain4.
[0084] The above embodiment uses the example of user A wanting to transfer 10 coins held on parachain1 to parachain3 and 20 coins held on parachain2 to parachain4, which is identified as the name of the parachain, to exemplarily illustrate the asset transfer principle of the present invention.
[0085] In more embodiments, the identifier can also be configured as other parameters according to actual needs. For example, assuming that the game-type parachain is configured with an identifier M, and parachain1 to parachain4 are all game-type parachains, then the first identifier in the first asset transfer transaction is M, and the second identifier of parachain1 to parachain4 is also M. Each parachain node of parachain1 to parachain4 will execute the corresponding transaction content in tx1, and the same technical effect can be achieved.
[0086] It should be noted that the parachain node of each parachain can first synchronize the first asset transfer transaction from the main chain, and then determine whether the first identifier in the first asset transfer transaction includes the second identifier of the parachain to which it belongs; or first determine whether the first identifier in the first asset transfer transaction includes the second identifier of the parachain to which it belongs: if yes, synchronize the first asset transfer transaction from the main chain and execute it. This is not limited here.
[0087] It should be noted that the parachain nodes of each parachain in the present application actively obtain the first asset transfer transaction from the main chain. Those skilled in the art should be able to imagine that, when the main chain node can execute the first asset transfer transaction and the first confirmation transaction, the main chain node can identify the parachains parachain1 to parachain4 included in the first asset transfer transaction and the first confirmation transaction, and push the first asset transfer transaction and the first confirmation transaction to the connected parachain nodes of parachain1 to parachain4.
[0088] It should be noted that those skilled in the art should understand that the coins frozen, generated, and deducted by executing tx1 and tx2 in the above embodiments are only references; the names of assets on different parallel chains should be different. For example, the asset name of parachain1 is aaa, the asset name of parachain2 is bbb, the asset name of parachain3 is ccc, and the asset name of parachain4 is ddd. Taking the transaction content (account(A)_pc1,-10aaa) executed by each parachain node of parachain1 as an example, when executing tx1, each parachain node on parachain3 should generate a number of bbbs corresponding to 10aaa in account(A) on parachain3, or generate a pseudo 10aaa in account(A) on parachain3; and, when executing tx2, each parachain node on parachain3, if all execution results are successful, each parachain node on parachain3 will unfreeze the corresponding number of bbbs or pseudo 10aaa generated frozen in account(A) on parachain3; if all execution results are not successful, each parachain node on parachain3 will deduct the corresponding number of bbbs or pseudo 10aaa generated frozen in account(A) on parachain3.
[0089] The above embodiment enables related transaction contents to be executed simultaneously with less handling fee.
[0090] Preferably, the above method further comprises:
[0091] Generate a first transfer transaction; wherein the first transfer transaction is a transfer transaction of the first parachain or the second parachain;
[0092] Send the first transfer transaction to the main chain for each main chain node to:
[0093] Determine whether all parallel chain blocks including the first asset transfer transaction have successfully reached consensus on the main chain:
[0094] If not, the first transfer transaction will not be packaged for the time being.
[0095] Specifically, user A's client generates a transfer transaction tx3 (account(A)_pc3,account(B)_pc3,10coin);
[0096] User A's client sends tx3 to the main chain;
[0097] Each main chain node determines whether the parallel chain blocks including tx1 have all reached consensus successfully on the main chain:
[0098] If not, tx3 will not be packaged for the time being.
[0099] The above embodiment ensures that different transactions of the same user are executed serially.
[0100] It should be noted that those skilled in the art should be able to imagine that, when the main chain node can execute the first asset transfer transaction and the first confirmation transaction, the first transfer transaction is not packaged temporarily, including:
[0101] Determine whether the corresponding first transaction content is to deduct certain assets:
[0102] If yes, the first transfer transaction will not be packaged yet.

[0112] If yes, execute the first confirmation transaction: obtain the execution result of the first asset transfer transaction that succeeded in each consensus from the main chain;
[0113] Determine whether all execution results are successful:
[0114] If yes, the frozen assets will be deducted, or the frozen assets generated will be unfrozen;

An asset transfer method, characterized in that: Applicable to a client, the method includes: in response to a current user transferring assets held on a plurality of first parallel chains to a plurality of second parallel chains, generating a first asset transfer transaction; wherein the first asset transfer transaction includes a first identifier of each of the first parallel chains and each of the second parallel chains, and first transaction contents executed on each of the first parallel chains and each of the second parallel chains respectively; Send the first asset transfer transaction to the main chain for each parachain node of each parachain: Determine whether the first identifier in the first asset transfer transaction includes the second identifier of the parachain to which it belongs: If yes, execute the corresponding first transaction content: If the corresponding first transaction content is to deduct certain assets, then freeze the certain assets; If the corresponding first transaction content is to generate a number of assets, then generate the several assets and freeze the generated several assets; and generate a consensus transaction of the parachain block including the first asset transfer transaction and send it to the main chain; wherein the second identifier is the unique identity identifier of each of the first parachains and each of the second parachains; When all the parachain blocks including the first asset transfer transaction have successfully reached consensus on the main chain, a first confirmation transaction including the transaction hash of the first asset transfer transaction is generated and sent to the main chain for each parachain node of each parachain: judging whether the first asset transfer transaction is included on the parachain to which it belongs according to the transaction hash: if yes, executing the first confirmation transaction: obtaining the execution results of each first asset transfer transaction that has successfully reached consensus from the main chain; Determine whether all the execution results are successful: If yes, the frozen assets shall be deducted, or the frozen assets generated shall be unfrozen; If not, the frozen assets will be unfrozen, or the frozen assets generated will be deducted.
2. The method according to claim 1, characterized in that: Also includes: Generate a first transfer transaction; wherein the first transfer transaction is a transfer transaction of the first parachain or the second parachain; The first transfer transaction is sent to the main chain for each main chain node to determine whether each parallel chain block including the first asset transfer transaction has successfully reached consensus on the main chain: if not, the first transfer transaction will not be packaged for the time being.
3. An asset transfer method, characterized in that: Applicable to main chain nodes, the method includes: receiving a first asset transfer transaction; wherein the first asset transfer transaction is generated by a first client of a first user in response to the first user transferring assets held on a number of first parallel chains to a number of second parallel chains, and the first asset transfer transaction includes a first identifier of each of the first parallel chains and each of the second parallel chains, and each first transaction content executed on each of the first parallel chains and each of the second parallel chains respectively; the first asset transfer transaction is also used for the parallel chain nodes of each parallel chain: judging whether the first identifier in the first asset transfer transaction includes the second identifier of the corresponding parallel chain: if yes, executing the corresponding first transaction content: If the corresponding first transaction content is to deduct certain assets, then freeze the certain assets; If the corresponding first transaction content is to generate a number of assets, then generate the several assets and freeze the generated several assets; and generate a consensus transaction of the parachain block including the first asset transfer transaction and send it to the main chain; wherein the second identifier is the unique identity identifier of each of the first parachains and each of the second parachains; Receive a first confirmation transaction including the transaction hash of the first asset transfer transaction; wherein the first confirmation transaction is generated by the first client when each parachain block including the first asset transfer transaction has successfully reached consensus on the main chain; the first confirmation transaction is also used for the parachain nodes of each parachain: determine whether the first asset transfer transaction is included on the parachain to which it belongs according to the transaction hash: if yes, execute the first confirmation transaction: obtain the execution results of each first asset transfer transaction that has successfully reached consensus from the main chain; Determine whether all the execution results are successful: If yes, the frozen assets shall be deducted, or the frozen assets generated shall be unfrozen; If not, the frozen assets will be unfrozen, or the frozen assets generated will be deducted.
4. The method according to claim 3, characterized in that Also includes: Receive a first transfer transaction; wherein the first transfer transaction is generated by the first client, and the first transfer transaction is a transfer transaction of the first parachain or the second parachain; Determine whether all parallel chain blocks including the first asset transfer transaction have successfully reached consensus on the main chain: if not, the first transfer transaction will not be packaged for the time being.
5. An asset transfer method, characterized in that: Applicable to a parachain node, the method comprises: obtaining a first asset transfer transaction from a main chain; wherein the first asset transfer transaction is generated by a first client of a first user in response to the first user transferring assets held on a plurality of first parachains to a plurality of second parachains, and the first asset transfer transaction comprises a first identifier of each of the first parachains and each of the second parachains, and first transaction contents respectively executed on each of the first parachains and each of the second parachains; Determine whether the first identifier in the first asset transfer transaction includes the second identifier of the current parallel chain: if yes, execute the corresponding first transaction content: If the corresponding first transaction content is to deduct certain assets, then freeze the certain assets; If the corresponding first transaction content is to generate a number of assets, then generate the several assets, freeze the generated several assets, and generate a consensus transaction of the parachain block including the first asset transfer transaction and send it to the main chain; wherein the second identifier is the unique identity identifier of each of the first parachains and each of the second parachains; Obtaining a first confirmation transaction including the transaction hash of the first asset transfer transaction from the main chain; wherein the first confirmation transaction is generated by the first client when all the parachain blocks including the first asset transfer transaction have successfully reached consensus on the main chain; Determine whether the first asset transfer transaction is included on the parallel chain according to the transaction hash: if yes, execute the first confirmation transaction: obtain the execution results of the first asset transfer transactions that have succeeded in consensus from the main chain; Determine whether all the execution results are successful: If yes, the frozen assets shall be deducted, or the frozen assets generated shall be unfrozen; If not, the frozen assets will be unfrozen, or the frozen assets generated will be deducted.
