Specifically, a main chain and ten parallel chains parachain 1-parachain 10 (named as pc 1-pc 10) are assumed in the block chain network; taking the identifiers (including the first identifier and the second identifier) as parallel chain names, the user A wants to transfer the 10c oil held by the user A on the parachain1 to the parachain3 and the 20coin held by the user A on the parachain2 to the parachain 4;
the client of the user a performs step S12, and in response to the user a wanting to transfer 10 coins held by the user a on the parachai n1 to parachain3 and 20 coins held by the user a on the parachain2 to parachain4, generates an asset transfer transaction tx 1; tx1 includes p c1, pc2, pc3, pc4, and transaction contents executed in correspondence with each parallel link of parachain1 (account (a) _ pc1, -10coin), transaction contents executed in correspondence with each parallel link of parachain2 (account (a) _ pc2, -20coin), transaction contents executed in correspondence with each parallel link of parachain 3(account (a) _ pc3, +10coin), transaction contents executed in correspondence with each parallel link of parachain4 (account (a) _ pc4, +20 coin);
the client of the user a performs the step S14, sending tx1 to the main chain;
backbone node certificate of existence tx 1; in further embodiments, the backbone node may also execute tx1, recording the first identifier and each first transaction content onto the backbone (i.e., pc1, pc2, pc3, p c4, and (account (a) _ pc1, -10 account), (account (a) _ pc2, -20 account), (account (a) _ pc3, +10 account), (account (a) _ pc4, +20 account);
each parallel chain link point of the parachain 1-10 judges whether the marks pc1, pc2, pc3 and pc4 in tx1 comprise the marks of the corresponding parallel chains:
tx1 includes pc1, then each parallel link point of parachain1 executes (account (a) _ pc1, -10coin), freezing 10 coins of account (a) on parachain 1;
tx1 includes pc2, then each parallel link point of parachain2 executes (account (a) _ pc2, -20 core), freezing 20 cores of account (a) on parachain 2;
tx1 includes pc3, then each parallel chain link point of parachain3 executes (account (a) _ pc3, +10coin), generates 10 coins in account (a) on parachain3, and freezes the generated 10 coins;
tx1 includes pc4, then each parallel chain link point of parachain4 executes (account (a) _ pc4, +20coin), generates 20 coins in account (a) on parachain4, and freezes the generated 20 coins;
tx1 does not include pc5 to pc10, then parallel link points of parachain5 to parachain10 do not execute tx 1;
the client of the user a performs step S16, and when the parallel chain blocks each including tx1 are successfully recognized in the main chain, generates a confirmation transaction tx2 including a hash (tx1) and sends the confirmation transaction tx2 to the main chain;
backbone node certificate of existence tx 2; in further embodiments, the backbone node may also perform tx2, recording a hash (tx1) onto the backbone;
judging whether each parallel chain node of the parachain 1-10 comprises tx1 according to the hash (tx 1):
since tx1 is included on the parachain 1-4, each parallel link point of the parachain 1-4 performs tx 2: obtaining the execution result of each successful tx1 from the main chain;
if each execution result is successful, each parallel chain link on the parachain1 deducts the frozen 10coin in the account (A) on the parachain 1; each parallel link on parachain2 subtracted the frozen 20-coin subtraction in account (a) on parachain 2; each parallel link on parachain3 thawed the 10 coins produced frozen in account (a) on parachain3, i.e. when there is 10 coins in account (a) on parachain 3; each parallel link on parachain4 thawed the 20 coins produced frozen in account (a) on parachain4, i.e. when there is 20 coins in account (a) on parachain 4;
if the execution results are not successful, then each parallel link on the parachain1 unfreezes the frozen 10 counts in the account (A) on the parachain 1; each parallel link on the parachain2 thawed the frozen 20 coins in account (a) on parachain 2; each parallel link on parachain3 deducts the resulting 10-coin frozen in account (a) on parachain 3; each parallel link on parachain4 deducts the resulting 20-coin frozen in account (A) on parachain 4.
The above embodiment illustrates the asset transfer principle of the present invention by way of example as identified as a parallel chain name, user a wants to transfer 10 coins that he holds on parachain1 to parachain3 and 20 coins that he holds on parachain2 to parachain 4.
In more embodiments, the identifiers may be configured as other parameters according to actual requirements, for example, assuming that the identifier M is configured on the parallel chain of the game class, and the parachain1 to the parachain4 are all parallel chains of the game class, the first identifier in the first asset transfer transaction is M, the second identifiers of the parachain1 to the parachain4 are also M, and each parallel chain node of the parachain1 to the parachain4 executes corresponding transaction content in tx1, so that the same technical effect may be achieved.
It should be noted that, the parallel chain node of each parallel chain may 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 corresponding parallel chain; or, firstly, judging whether the first identifier in the first asset transfer transaction comprises a second identifier of the parallel chain: if so, then the first asset transfer transaction is synchronized from the main chain and executed. And is not limited herein.
It should be noted that, in the present application, the parallel link point of each parallel chain actively acquires the first asset transfer transaction from the main chain, and it should be understood by those skilled in the art that, in the case that the main chain node can execute the first asset transfer transaction and the first confirmation transaction, the main chain node can identify the parallel chain parachain 1-pa rachain4 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 parallel chain node of the connected par achain 1-parachain 4.
It should be noted that those skilled in the art should understand that the coins frozen, generated and subtracted by tx1 and tx2 in the above embodiments are only used as references; the names of the assets should be different on different parallel chains, 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 executed correspondingly by each parallel link point of the parachain1 as (accou nt (a) _ pc1, -10aaa) as an example, each parallel link node on the parachain3 should generate several bbbs corresponding to 10aaa in account (a) on the parachain3 or pseudo 10aaa in account (a) on the parachain3 when tx1 is executed; and when each parallel chain node on the parachain3 executes tx2, if each execution result is successful, each parallel chain link on pa rachain3 unfreezes the corresponding generated bbb or pseudo 10aaa frozen in account (a) on parachain3, and if each execution result is not successful, each parallel chain link on parachain3 subtracts the corresponding generated bbb or pseudo 10aaa frozen in account (a) on parachain 3.
The above embodiment enables the related transaction contents to be executed simultaneously with less commission cost.
Preferably, the method further comprises:
generating a first transfer transaction; wherein the first transfer transaction is a transfer transaction of a first parallel chain or a second parallel chain;
sending a first transfer transaction to the main chain for each main chain node:
determining whether each parallel chain block comprising the first asset transfer transaction is successfully identified in the main chain:
and if not, temporarily not packaging the first transfer transaction.
Specifically, the client of user A generates the transfer transaction tx3(account (A) _ pc3, acount (B) _ pc3,10 coin);
user A's client sends tx3 to the backbone;
each main chain node judges whether the parallel chain blocks comprising tx1 are successfully identified in the main chain:
otherwise, tx3 is not packed for the time being.
The above-described embodiments ensure that different transactions of the same user are performed serially.
It should be noted that, as those skilled in the art can imagine, in the case where the main chain node can execute the first asset transfer transaction and the first confirmation transaction, the first forwarding transaction is not packaged for the moment, including:
determining whether the corresponding first transaction content is a deducted plurality of assets:
if so, the first transfer transaction is not packaged for the time being.
