Referring to fig. 1, fig. 1 is a flowchart illustrating a method for data transaction between multiple blockchains according to a preferred embodiment of the present invention. The data transaction method based on the multi-block chain is applied to a first client, the first client has the function of adding a plurality of different block chains, the sequence of steps in the flow chart can be changed according to different requirements, and some steps can be omitted.
S11, the first client receives a transaction request triggered on the first block chain.
When a plurality of block chains authorized mutually exist, the client sides corresponding to the plurality of block chains can be packaged, integrated and authorized, namely, the multi-functionalization of the client sides is realized, so that the client sides capable of adding the plurality of block chains are obtained, namely, the obtained client sides have the function of adding the plurality of block chains. The method includes the steps that clients corresponding to a plurality of block chains are packaged and integrated, and belongs to the prior art, and the authorization is not repeated herein, namely, the use permission of a merchant corresponding to the block chains is obtained, if the merchant develops an internal interface, the internal interface can be used for calling the plurality of block chains, and mutual authorization of the plurality of block chains is achieved.
In the embodiment of the present invention, the first client has a function of adding multiple different blockchains, that is, the first client can add at least two blockchains, and the specific amount of addition is determined by a user. The first client is any one client on the block chain network.
In an embodiment of the present invention, when data transaction needs to be performed at two addresses on the second blockchain, for example, the address X is transferred to the address Y by 100token, the first client may receive a transaction request triggered on the first blockchain, where the transaction request is used to request that a transaction be initiated between the first address and the second address on the second blockchain. The first address and the second address are both addresses for storing tokens. The first client may only add the first blockchain, or the first client may add the first blockchain and the second blockchain at the same time, or the first client may add more than three blockchains at the same time, which is not limited in the embodiment of the present invention.
As an optional implementation manner, before step S11, the method further includes:
generating account information for each blockchain the first client is to join.
In this alternative embodiment, since the first client is obtained after encapsulating, integrating and authorizing the multiple clients, and the blockchain addresses of the multiple clients are no longer applicable to the first client before processing, for the first client, account information needs to be generated for each blockchain to which the first client is to join, for example, address information of an account on which token is stored on the first client. The generated address information may be an address used in multiple block chains, or an address generated for each block chain. When the user uses the address list for the first time, the user can select to create a plurality of address lists which are used together, or can select to create a single address, and each address can only be used on the own chain. Generally, if multiple block chains use the same address format, one address may be used for multiple block chains, and when different address formats are used, only one block chain may correspond to one address.
As an optional implementation, the method further comprises:
receiving a blockchain selection instruction input on a blockchain list, wherein the blockchain list comprises a plurality of blockchains which can be added by the first client;
and responding to the block chain selection instruction, and adding the selected at least one block chain to the first client.
In this alternative embodiment, although the first client has the function of being able to join multiple blockchains, the joining of the multiple blockchains by the first client is determined by the selection of the user, and the user can select and input a blockchain selection instruction on a blockchain list, where the blockchain list includes the multiple blockchains that the first client can join; the first client may respond to the block chain selection instruction, and add the selected at least one block chain to the first client, that is, the first client may add only one block chain or add multiple block chains.
And S12, the first client judges whether the first client joins the second block chain, if so, the step S13 is executed, and if not, the process is ended.
In the embodiment of the present invention, the first client needs to first determine whether the first client joins the second blockchain, and if the first client joins the second blockchain, the first client may respond to the transaction request by itself. If the first client does not join the second blockchain, the transaction request needs to be responded by other clients simultaneously joining the first blockchain and the second blockchain.
As an optional implementation, the method further comprises:
and if the first client does not join the second blockchain, broadcasting the transaction request on the first blockchain.
In this optional embodiment, the first client only joins the first blockchain, and when the first client receives a triggered transaction request on the first blockchain, the first client needs to broadcast the transaction request on the first blockchain, and the client joining the first blockchain and the second blockchain at the same time on the first blockchain verifies the transaction request, and the client not joining the first blockchain and the second blockchain at the same time discards the broadcasted transaction request; after the transaction request is verified to be effective, the first blockchain and the second blockchain are added at the same time, the client which responds to the transaction request most quickly responds to the transaction request, the transaction is carried out between the first address and the second address on the second blockchain, a transaction result is obtained, and the transaction result is transmitted back to the first blockchain through the second blockchain, so that the transaction request is completed through the client which is added to the first blockchain and the client which is added to the second blockchain at the same time.
And S13, the first client broadcasts the transaction request on the first block chain.
In this embodiment of the present invention, the first client joins the first blockchain and the second blockchain at the same time, and when the first client receives a triggered transaction request on the first blockchain, the first client needs to broadcast the transaction request on the first blockchain.
And S14, after the transaction request is verified to be effective, the first client sends the transaction request to the second block chain, initiates a transaction between the first address and the second address on the second block chain to obtain a transaction result, and the transaction result is transmitted back to the first block chain through the second block chain.
In this embodiment of the present invention, other clients (such as a third client) joining the first blockchain and the second blockchain at the same time on the first blockchain verify the transaction request, and a client not joining the first blockchain and the second blockchain at the same time discards the broadcasted transaction request; after the verification is valid, the first client sends the transaction request to the second block chain, and initiates a transaction between the first address and the second address on the second block chain to obtain a transaction result, that is, data on the account of the first address is transferred to the account of the second address, and the transaction result is transmitted back to the first block chain through the second block chain. The transaction result is the data change condition of the accounts with two addresses, namely the data reduction amount on the account with the first address, the data increase amount on the account with the second address and the data change amount.
The specific process of the third client for verifying the transaction request is as follows:
the third client side is used for verifying the transaction request, judging whether the first address and the second address exist in the second block chain at the same time, if so, judging whether total data on the first address is larger than or equal to transaction data required by the transaction request, and if so, determining that the transaction request is verified, namely, the necessary condition that the second block chain needs to exist the first address and the second address at the same time, and the total data on the first address is larger than or equal to the transaction data required by the transaction request. Further, a second number of validated transactions needs to be counted, and if the second number of validated transactions exceeds the preset threshold, it is determined that the transaction request is validated.
S15, the first client broadcasts a verification request aiming at the transaction result on the first block chain.
And verifying the transaction result by a second client on the first blockchain, wherein the second client is a client except the first client in the clients simultaneously joining the first blockchain and the second blockchain.
Specifically, whether the data change of the account with the first address is matched with the data change of the account with the second address is verified, namely whether the data reduction amount of the account with the first address is equal to the data increase amount of the account with the second address and whether the number of the data changes is equal to the transaction data of the transaction result. Finally, the number of the second client end passing the verification of the transaction result can be counted, and if the number exceeds the preset threshold value, the transaction result can be determined to be valid, so that the client end can be prevented from doing harm, and the reliability of data transaction is ensured.
S16, the first client side counts the first number of the second client side for passing the verification of the transaction result.
The number of the second clients is multiple, in order to verify the reliability of the transaction result, the whole network verification is required, and the first client can count the first number of the second clients which pass the verification of the transaction result.
And S17, if the first quantity exceeds a preset threshold value, the first client determines that the transaction result takes effect.
A preset threshold may be preset, for example, a number of the second clients is a, and the preset threshold may be set to a/2, that is, if the counted first number exceeds half, it may be determined that the transaction result is valid, that is, the data transaction is successful.
In the method flow described in fig. 1, a transaction request triggered on a first blockchain may be received, where the transaction request is used to request that a transaction be initiated between a first address and a second address on a second blockchain, and whether the first client joins the second blockchain may be determined; if the first client side is added into the second block chain, the transaction request is broadcasted on the first block chain, after the transaction request is verified to be valid, the transaction request is sent to the second block chain, transaction is initiated between the first address and the second address on the second block chain, a transaction result is obtained, and the transaction result is transmitted back to the first block chain through the second block chain; further, a verification request for the transaction result is broadcasted on the first blockchain, wherein the transaction result is verified by a second client on the first blockchain, and the second client is a client except the first client in the clients joining the first blockchain and the second blockchain at the same time; finally, a first number of verifications of the transaction result by the second client may be counted; and if the first quantity exceeds a preset threshold value, determining that the transaction result is effective. Therefore, in the invention, after the verification of the transaction request in the whole network takes effect, the client capable of working on a plurality of block chains at the same time is selected to serve as a medium among the plurality of block chains, the transaction request triggered on the first block chain is transferred to the second block chain, and after the transaction is completed on the second block chain, the client working on the plurality of block chains at the same time carries out the verification of the whole network on the transaction result, thereby not only realizing the cross-chain communication, but also ensuring the reliability of the transaction result.
The above description is only a specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and it will be apparent to those skilled in the art that modifications may be made without departing from the inventive concept of the present invention, and these modifications are within the scope of the present invention.
