The present invention provides a data communication method based on a block chain, and referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of the data communication method based on the block chain according to the present invention.
In this embodiment, the data communication method based on the block chain includes:
step S100, when a cross-chain transaction request is received, acquiring transaction information corresponding to the cross-chain transaction request, and constructing the transaction information as test transaction information;
in this embodiment, the cross-chain transaction request is a cross-chain transaction request sent by an initiator of the cross-chain transaction request, where a link where the initiator corresponding to the cross-chain transaction request is located is a source chain, and the source chain may be a main chain or a side chain in the current block chain system; the link where the receiver corresponding to the cross-link transaction request is located is the target link, which may also be the corresponding side chain or main chain in the current block chain system. When a cross-chain transaction request sent by a source account based on a source chain in the blockchain system is received, it indicates that a transaction asset in transaction information corresponding to the cross-chain transaction request needs to be transferred to a target account on a target chain currently.
Specifically, when the cross-chain transaction request is received, the cross-chain transaction request is broadcast to a verification node in a cross-chain consensus region of the source chain and the target chain, and when the verification node receives the cross-chain transaction request, transaction information corresponding to the cross-chain transaction request is acquired, and corresponding test transaction information is constructed according to the transaction information. In order to ensure the safety of the current transaction, when the transaction information corresponding to the cross-chain transaction request is obtained, the transaction information can be constructed as the test transaction information according to the first account of the initiator of the transaction information and the second account of the target party corresponding to the transaction information. Specifically, the first account is a one-time account of a source account of a current initiator, and the second account is a one-time account established by the initiator to a target party. The initiator constructs transaction signature and contract use data in the intelligent contract through the corresponding private key, the first account and the second account. When the transaction signature and contract use data in the intelligent contract are obtained, the initiator randomly selects a plurality of signature accounts in the current block chain network to form a ring signature public key set (namely a ring signature) of the transaction information; and finally, the initiator constructs the transaction information into final test transaction information through the transaction signature, the contract use data and the ring signature.
Step S200, verifying the test transaction information and determining whether the test transaction information is valid;
in this embodiment, when the transaction information is constructed as test transaction information, the test transaction information is verified. Wherein a cross-chain consensus region exists between the side chain and the main chain; the chain-crossing consensus region comprises partial nodes of the main chain and the side chain respectively, and each node included in the chain-crossing consensus region is a verification node. According to the verification node, when the side chain and the main chain carry out cross-chain transaction, the current test transaction information can be identified and verified.
Specifically, a ring signature of the current test transaction information is obtained, where the ring signature is a signature public key set formed by a signer (i.e., an initiator of the current test transaction information) and a signature account randomly selected from a current blockchain account system. When the ring signature of the current test transaction information is obtained, a corresponding judgment result is obtained through a preset function according to the transaction content of the current test transaction information and the ring signature, and whether the ring signature is legal or not is determined according to the judgment result. If the judgment result accords with a preset judgment result, the ring signature is determined to be legal; and if the judgment result does not accord with the preset judgment result, determining that the ring signature is illegal. When the ring signature is determined to be legal, the current test transaction information is determined to be verified.
Step S300, when the test transaction information passes the verification, determining that the test transaction information is valid, and executing the operation corresponding to the cross-chain transaction request.
In this embodiment, when the test transaction information passes verification, the operation corresponding to the current cross-chain transaction request is executed. Wherein the cross-chain transaction request can be a data transfer request.
After the operation corresponding to the cross-chain transaction request is executed, it is necessary to determine whether the transaction corresponding to the current cross-chain transaction request is successful. And if the transaction corresponding to the current cross-chain transaction request is successful, acquiring the transaction success receipt information, and returning the receipt information to the source chain where the sender of the cross-chain transaction request is located.
According to the data communication method based on the block chain, when a cross-chain transaction request is received, transaction information corresponding to the cross-chain transaction request is obtained, the transaction information is constructed to be test transaction information, then the test transaction information is verified, whether the test transaction information is valid or not is determined, then when the test transaction information is verified to be passed, the test transaction information is determined to be valid, and operation corresponding to the cross-chain transaction request is executed, so that efficient and rapid cross-chain transaction is achieved while safety transaction is guaranteed, centralization of a cross-chain common identification area is avoided, safety and reliability of the cross-chain transaction are improved, and privacy safety of both sides of the transaction are guaranteed.
Based on the first embodiment, a second embodiment of the data communication method based on the block chain according to the present invention is proposed, and referring to fig. 3, in this embodiment, step S200 includes:
step S210, determining a cross-chain consensus area of a source chain and a target chain corresponding to the cross-chain transaction request;
step S220, verifying the test transaction information based on the cross-chain consensus region.
In this embodiment, a cross-chain consensus region exists between the side chain and the main chain, where the cross-chain consensus region includes partial nodes of the main chain and the side chain, respectively, as shown in fig. 4, fig. 4 is a schematic diagram of the cross-chain consensus region between the main chain and the side chain, and a cross-chain consensus region a and a cross-chain consensus region B exist between the main chain consensus chain and the side chain a consensus chain and the side chain B consensus chain, respectively; the chain-crossing consensus domain A is composed of a plurality of main chain consensus nodes in the main chain consensus chain and a plurality of A chain link points of the side chain A consensus chain, and the chain-crossing consensus domain B is composed of a plurality of main chain consensus nodes in the main chain consensus chain and a plurality of B chain link points of the side chain B consensus chain.
Each node included in the cross-chain consensus region is a verification node, and according to the verification node, consensus verification can be performed on the current test transaction information when cross-chain transaction is performed between the side chain and the main chain. Specifically, when the verification node is used for verifying the current test transaction information, a ring signature of the current test transaction information is obtained, where the ring signature is a signature public key set formed by a signer (i.e., an initiator of the current test transaction information) and a signature account randomly selected from a current blockchain account system. When the ring signature of the current test transaction information is obtained, a corresponding judgment result is obtained through a preset function according to the transaction content of the current test transaction information and the ring signature, and whether the ring signature is legal or not is determined according to the judgment result. If the judgment result accords with a preset judgment result, the ring signature is determined to be legal; and if the judgment result does not accord with the preset judgment result, determining that the ring signature is illegal. When the ring signature is determined to be legal, the current test transaction information is determined to be verified.
Particularly, in the cross-chain transaction, if a correct cross-chain transaction certificate is provided, the verification node can acquire a transaction reward of a corresponding share; if the verification node provides false cross-chain transaction certification in cross-chain transaction, whether the cross-chain transaction verification qualification of the node is cancelled and whether the deposit is deducted can be determined according to the number of the false cross-chain transaction certification.
According to the data communication method based on the block chain, the cross-chain common identification area of the source chain and the target chain corresponding to the cross-chain transaction request is determined, and then the test transaction information is verified based on the cross-chain common identification area, so that the verification of the test transaction information through the ring signature is realized, the anonymous protection of signer information is ensured when the transaction is carried out, the transaction signer cannot be tracked, and the information privacy protection of the block chain transaction is further realized.
Based on the second embodiment, a third embodiment of the data communication method based on the block chain according to the present invention is proposed, and referring to fig. 5, in this embodiment, step S200 includes:
step S221, acquiring a ring signature of the test transaction information;
step S222, verifying the validity of the ring signature, and determining that the test transaction information passes verification when the ring signature is verified to be valid.
In this embodiment, in order to ensure privacy and security of the transaction and make the initiator of the transaction information untraceable, the initiator of the transaction information performs a ring signature process on the transaction information. Specifically, when a signer (i.e. the initiator of the current test transaction information) constructs a ring signature of the transaction information, a plurality of accounts are randomly selected from a current block chain, the accounts are signature accounts, and the transaction information is jointly signed by the signature accounts and the signer, so that a ring signature public key set of the transaction information can be formed; and when the ring signature is constructed successfully, constructing final test transaction information according to the current transaction information and the ring signature. When the verification node verifies the legal information, the legal information is analyzed to obtain a ring signature and transaction information of the legal information, a corresponding judgment result is obtained through a preset function according to the transaction content and the ring signature of the current test transaction information, and whether the ring signature is legal or not is determined according to the judgment result. If the judgment result accords with a preset judgment result, the ring signature is determined to be legal; when the ring signature is determined to be legal, the current test transaction information is determined to be verified.
According to the data communication method based on the block chain, the ring signature of the test transaction information is obtained, then the validity of the ring signature is verified, when the ring signature is verified to be legal, the test transaction information is determined to be verified to be passed, the verification of the current test transaction information according to the ring signature is achieved, and further the information privacy protection of the block chain transaction is achieved during transaction.
Based on the first embodiment, a fourth embodiment of the data communication method based on the block chain according to the present invention is proposed, and referring to fig. 6, in this embodiment, step S100 includes:
step S110, constructing a one-time account of the target account corresponding to the cross-chain transaction request;
and step S120, constructing the transaction information as test transaction information based on the one-time account.
In this embodiment, when a cross-chain transaction request is received, in order to ensure privacy and security of a transaction, transaction information corresponding to the cross-chain transaction request is acquired, and the transaction information is constructed as test transaction information based on the transaction information, so that the transaction information is a safe and legal effective transaction in a transaction process.
Specifically, when the transaction information is acquired, the initiator of the transaction information acquires a one-time account of the initiator, namely a first account, and establishes a one-time account, namely a second account, for the target party corresponding to the transaction information; and when the first account and the second account are obtained, the initiator constructs a transaction signature and contract use data in the intelligent contract through the corresponding private key, the first account and the second account. When the transaction signature and contract use data in the intelligent contract are obtained, the initiator randomly selects a plurality of signature accounts in the current block chain network to form a ring signature public key set (namely a ring signature) of the transaction information; and finally, the initiator constructs the transaction information into final test transaction information through the transaction signature, the contract use data and the ring signature.
According to the data communication method based on the blockchain, the one-time account of the target account corresponding to the cross-chain transaction request is constructed, and then the transaction information is constructed as the test transaction information based on the one-time account, so that the one-time accounts of both transaction parties are established, the corresponding test transaction information is constructed through the one-time account, the privacy of both transaction parties is further protected, and the transaction safety is guaranteed.
A fifth embodiment of the data communication method based on a block chain according to the present invention is proposed based on the first embodiment.
In this embodiment, when the test transaction information corresponding to the cross-chain transaction request passes verification, it is determined whether the cross-chain transaction request is a data transfer-in request, and it may be determined whether the cross-chain transaction request is a data transfer-in request according to the identification information in the cross-chain transaction request. If the cross-chain transaction request is a data transfer request, it means that the transaction assets in the transaction information corresponding to the data transfer request are required to be transferred to the target account on the target chain at present.
Based on the fifth embodiment, a sixth embodiment of the data communication method based on the block chain of the present invention is proposed, and referring to fig. 7, in this embodiment, after step S300, the data communication method based on the block chain further includes:

step S340, when it is determined that the transaction corresponding to the cross-chain transaction request is successful, obtaining receipt information of the successful transaction, and returning the receipt information to the source account corresponding to the cross-chain transaction request.
In this embodiment, after the operation corresponding to the cross-chain transaction request is executed, it is determined whether the transaction corresponding to the current cross-chain transaction request is successful. Specifically, according to an execution result of the intelligent contract corresponding to the current transaction, whether the transaction corresponding to the current cross-chain transaction request is successful or not can be determined, and if the execution result is confirmed, the transaction corresponding to the current cross-chain transaction request is determined to be successful; and if the execution result is not confirmed, determining that the transaction corresponding to the current cross-chain transaction request fails. And when the transaction corresponding to the current cross-chain transaction request is determined to be successful, acquiring transaction success receipt information, and returning the receipt information to the source chain where the sender of the cross-chain transaction request is located, wherein the receipt information is identification information of the transaction success corresponding to the current cross-chain transaction request, and the source account of the source chain corresponding to the cross-chain transaction request can be used for determining that the current transaction is successfully executed according to the receipt information.
In the data communication method based on the blockchain, provided by this embodiment, by determining whether the transaction corresponding to the cross-chain transaction request is successful, and then obtaining receipt information of the successful transaction when determining that the transaction corresponding to the cross-chain transaction request is successful, and returning the receipt information to the source account corresponding to the cross-chain transaction request, it is achieved that whether the transaction corresponding to the cross-chain transaction request is successful is determined, so that the initiator can know the information in the first time when the current transaction is successfully executed.
