Based on the above problems, embodiments of the present application provide a method, a system, an electronic device, and a computer readable storage medium for processing a blockchain transaction, which can improve the efficiency of performing the blockchain transaction on an account that does not hold a native token.

The following detailed description is provided with reference to the accompanying drawings. The following description of the embodiments is not intended to limit the preferred embodiments. Although a logical order is depicted in the flowchart, in some cases the steps shown or described may be performed in an order different than depicted in the figures.

In this embodiment, taking an example that an agent node and an intelligent contract node are applied to a terminal as an example, the present embodiment provides a processing method of a blockchain transaction, as shown in fig. 2, a specific flow of the processing method of the blockchain transaction may be as follows:

201. the agent node receives a transaction request sent by a transaction initiating account, wherein the transaction request comprises transaction content, the transaction content comprises account information of a transaction receiving account, a first virtual token amount transacted with the transaction receiving account, and a second virtual token amount paid to the agent node.

The transaction initiating account is an account initiating the transaction, the transmitted transaction request is used for carrying out the transaction on the blockchain with the transaction receiving account, and the transaction receiving account is an account carrying out the transaction with the transaction initiating account. It will be appreciated that the transaction initiating account and the transaction receiving account need to be on a blockchain, and may be held by the same user or different users, and may be specifically determined based on the actual application scenario, which is not limited herein.

The account information of the transaction receiving account is information for identifying the transaction receiving account, and includes, but is not limited to, an account number of the transaction receiving account, an address of the transaction receiving account on a blockchain, a characteristic identifier of the transaction receiving account, and the like.

The first virtual token amount transacted with the transaction receiving account is used for indicating the token amount of the transaction initiating account and the transaction receiving account currently transacted, and may be the token amount transferred from the transaction initiating account to the transaction receiving account, or may be the token amount acquired from the transaction receiving account by the transaction initiating account, which may be specifically determined based on the actual application scenario, and is not limited herein.

It can be appreciated that, since one account needs to pay the Gas fee generated in the transaction process by the native token if it wants to realize the transaction with another account on one blockchain, and in the case that the account does not have the native token corresponding to the blockchain where the account is currently located, a proxy node is introduced in this embodiment, that is, the proxy node is used to proxy the account to send the transaction request that the transaction initiating account wants to make to the intelligent contract node, and the proxy node needs to have the native token.

The transaction request sent by the transaction initiating account to the proxy node needs to include a second virtual token amount paid to the proxy node, wherein the second virtual token amount is the token amount transferred by the transaction initiating account to the corresponding account of the proxy node, and is used as the proxy fee of the proxy node, and the amount is the willingness paid by the transaction initiating account.

In some embodiments, the transaction content further includes a current transaction number corresponding to the transaction initiation account, and the account information of the transaction receiving account, the first virtual token amount, the second virtual token amount, and the current transaction number are represented in a form of four-tuple.

It can be understood that, because there may be a request that the proxy node has received for the transaction initiation account that has been initiated, i.e., the proxy node has received the request before the request is received this time, in order to prevent replay attacks, in this embodiment, the transaction number is introduced, i.e., when the transaction initiation account sends the transaction request, the transaction content of the transaction request further includes the current transaction number corresponding to the current transaction of the transaction initiation account, so that the proxy node queries whether it proxies the transaction this time. The transaction times are self-increment corresponding to the transaction initiating account, namely the transaction times are accumulated when the transaction initiating account initiates the transaction each time, for example, 1 is added, so that each transaction can only have one validity.

For example, the representation of the four-tuple may be (dest 1, current, fe, nonce), where dest1 in the four-tuple is account information of the transaction receiving account; the amounts in the quadruple are a first virtual token amount; fee in the quadruple is a second virtual token amount; the nonce in the quadruple is the current transaction number corresponding to the transaction initiating account, and the value can be determined according to the actual transaction number of the transaction initiating account, for example, the first transaction of the transaction initiating account on the current blockchain, then the nonce can be set to 1 or 0, specifically, the nonce is set based on the actual requirement, and is not limited herein.

In some embodiments, the transaction content further includes signature information generated by signing the transaction initiating account for the transaction content, so as to verify whether the transaction content is signed by the transaction initiating account based on the signature information, that is, to verify the validity of the transaction. If the account information of the transaction receiving account, the first virtual token amount, the second virtual token amount and the current transaction number in the transaction content are expressed in a form of a quadruple, the signature information is signature information corresponding to the signature of the quadruple by the transaction initiating account.

For example, if the transaction initiation account is set to be an account a held by the user, there are 100 virtual tokens token in the account a, the account a is on the ETH blockchain, and there are no native tokens corresponding to the ETH blockchain in which the account a is currently located, that is, the ETH tokens. Then, the user is set to hold account B on the ETH blockchain, and there is an ETH token in account B, and the user wants to transfer the virtual token in account a held by the user to account B held by the user for portability of later use.

However, since the primary token does not exist in the account a, in order to implement the transfer of the virtual token, the account a may send a transaction request to the proxy node, so that the proxy node receives the transaction request sent by the account a, where the account information of the transaction receiving account, the first virtual token amount, the second virtual token amount and the current transaction number in the transaction content of the transaction request may be represented in the form of a quadruple, and the transaction request further includes signing the quadruple by the account a to obtain signature information (recorded as sig). Wherein the representation of the quadruple in this example is as follows:

(B，90，10，0)

Wherein B in the quadruple is account B; 90 in the quadruple is the first virtual token amount, namely, the token amount of the virtual token transferred from the account A to the account B is 90; 10 in the quadruple is the second virtual token amount, namely, the token amount of virtual token transferred by the account A to the proxy node is 10; and 0 in the quadruple is used for indicating that the current transaction number corresponding to the account A is the first transaction.

202. The proxy node generates a proxy transaction request based on the transaction request, sends the proxy transaction request to the smart contract node, and pays the smart contract node with a native token required to complete the proxy transaction request, wherein the proxy transaction request includes account information of the transaction initiating account and the transaction receiving account, the first virtual token amount, and the second virtual token amount.

The account information of the transaction initiating account is information for identifying the transaction initiating account, and includes, but is not limited to, an account number of the transaction initiating account, an address of the transaction initiating account on a blockchain, a characteristic identifier of the transaction initiating account, and the like.

In this embodiment, after receiving the transaction request sent by the transaction initiation account, the proxy node may further process the transaction request to generate a proxy transaction request consistent with the transaction content corresponding to the transaction request, and the proxy node needs to pay the smart contract node for the native token required for completing the transaction content corresponding to the transaction request, where the native token may be collected by the smart contract node before processing the transaction content or may be collected by the smart contract node after processing the transaction content, which may specifically be determined based on an actual scenario, and is not limited herein.

The proxy transaction request sent by the proxy node to the intelligent contract node is to realize the transaction content requested by the transaction initiating account, so that the proxy transaction request needs to include account information of the transaction initiating account and the transaction receiving account, the first virtual token amount and the second virtual token amount, so that the intelligent contract can conduct corresponding transaction based on the content carried in the proxy transaction request.

In some embodiments, the proxy node generating a proxy transaction request based on the transaction request may include: the agent node assembles signature information generated by the transaction content in the transaction request, the transaction initiating account for sending the transaction request and the signature of the transaction initiating account on the transaction content in the transaction request to obtain an agent transaction request which is required to be sent to the intelligent contract node by the agent node.

In this embodiment, the terminal corresponding to the proxy node may process the proxy transaction request through a preset proxy protocol based on the transaction request, so as to obtain a proxy transaction request, where the proxy protocol may be integrated with the original token protocol by an interface manner, so as to implement that a transaction initiation account without a native token is proxy for transaction.

Specifically, based on the transaction content (dest 1, amount, fe, nonce) and the signature information sig in the transaction request, a proxy transaction request may be generated, in which the content transfer_by_paytoken is represented as follows:

transfer_by_payTheToken(source，dest1，amount，fee，sig)

the source is account information of a transaction initiation account; the dest1 is account information of a transaction receiving account; the amountis a first virtual token amount; the fee is a second virtual token amount; the sig is signature information of a transaction initiation account pair (dest 1, amountfee, nonce).

Illustratively, based on the above example, the representation of the content transfer_by_paytoken in the proxy transaction request is as follows:

transfer_by_payTheToken(A，B，90，10，sig)

wherein, the A is account A; the B is account B; the value 90 is the first virtual token amount, that is, the token amount of the virtual token transferred from account a to account B is 90; the value 10 is the second virtual token amount, that is, the token amount of the virtual token transferred from the account a to the agent node is 10; the sig is signature information of a transaction initiating account pair (B, 90, 10, nonce).

In some embodiments, to avoid the occurrence of an invalid proxy, the proxy node needs to perform validity check on the received transaction request before generating the proxy transaction request based on the transaction request, for example, whether the transaction content of the proxy node proxy is valid or not, or whether the total amount of virtual tokens in the transaction initiation account proxied by the proxy node is enough to support the proxy node to perform proxy transaction, so that the validity check is performed on the transaction request before generating the proxy transaction request, if the verification is passed, the proxy node generates the proxy transaction request based on the transaction request, if the verification is not passed, the proxy node may not feed back any information, or feed back the verification failure information to the transaction initiation account, so that the transaction initiation account determines whether to continue to send the transaction request to the proxy node based on the verification failure information, and whether to adjust the transaction content in the transaction request.

Wherein the proxy node may verify the transaction request by at least one of the following verification means; when the transaction request is checked in at least two ways, if the check of at least one check means is not passed, the proxy node is considered to not pass the check of the transaction request.

The verification failure information fed back by the proxy node to the transaction initiating account includes, but is not limited to, verification failure reasons, suggested measures for the verification failure phenomenon and the like.

Specifically, before the proxy node generates the proxy transaction request based on the transaction request, the method may further include: the agent node querying a virtual token total in the transaction initiating account; the agent node calculating a sum of the first virtual token amount and the second virtual token amount; then, the agent node judges the size between the sum and the total amount of the virtual tokens, and if the sum is smaller than or equal to the total amount of the virtual tokens, the agent node generates an agent transaction request based on the transaction request; if the sum is greater than the total amount of the virtual tokens, a check fail message may be fed back.

Specifically, before the proxy node generates the proxy transaction request based on the transaction request, the method may further include: the agent node acquires the historical agent transaction times of the transaction initiating account and the current agent transaction times of the transaction initiating account; then, the agent node judges whether the historical agent transaction times are matched with the current agent transaction times or not, and if the historical agent transaction times are matched with the current agent transaction times, the agent node generates an agent transaction request based on the transaction request; if the historical proxy transaction times are not matched with the current proxy transaction times, the non-passing information can be fed back and checked.

Specifically, to avoid that the transaction receiving account does not accept the transaction, before the proxy node generates the proxy transaction request based on the transaction request, the method may further include: the proxy node further includes, before generating a proxy transaction request based on the transaction request: the agent node generates an authorized agent request based on the transaction request, and transmits the authorized agent request to the transaction receiving account so that the transaction receiving account feeds back information based on the authorized agent request, wherein the transaction receiving account comprises account information of the transaction initiating account and the first virtual token amount. If the proxy node receives the agreement proxy information fed back by the transaction receiving account, the proxy node generates a proxy transaction request based on the transaction request; if the proxy node receives the disagreement proxy information fed back by the transaction receiving account, the proxy node can feed back related information to the transaction initiating account.

203. The smart contract node receives the proxy transaction request, performs a transaction of the first virtual token amount between the transaction initiating account and the transaction receiving account based on the proxy transaction request, and performs a transaction of the second virtual token amount between the transaction initiating account and the proxy node.

In this embodiment, after the intelligent contract node receives the proxy transaction request sent by the proxy node, the intelligent contract node may perform a corresponding transaction based on the transaction content in the proxy transaction request, that is, between the transaction initiating account and the transaction receiving account, and perform a corresponding transaction between the transaction initiating account and the proxy node, so that the transaction between the transaction initiating account and the transaction receiving account can be proxied through the proxy node, thereby avoiding the waste of resources and time caused by transferring the native token to the transaction initiating account, and improving the efficiency of performing the blockchain transaction for the account not holding the native token.

In some embodiments, to improve security during the transaction, the smart contract node performs a validity check on the proxy transaction request received by the smart contract node before performing the transaction based on the proxy transaction request, for example, whether the transaction content of the proxy transaction request is valid, so that the proxy transaction request needs to be validated before performing the transaction, and if the validation passes, the smart contract node performs a transaction of the first virtual token amount between the transaction initiation account and the transaction receipt account and performs a transaction of the second virtual token amount between the transaction initiation account and the proxy node based on the proxy transaction request; if the verification is not passed, the intelligent contract node may not feed back any information, and may feed back the verification failure information to the transaction initiating account, or feed back the verification failure information to the proxy node, so that the proxy node sends the verification failure information to the transaction initiating account, thereby causing the transaction initiating account to determine whether to continue sending the transaction request to the proxy node and whether to adjust the transaction content in the transaction request based on the verification failure information.

Wherein the smart contract node may verify the proxy transaction request by at least one of the following verification means; when the proxy transaction request is checked in at least two ways, if the check of at least one check means is not passed, the intelligent contract node is considered to not pass the check of the proxy transaction request.

The verification failure information fed back by the intelligent contract node includes, but is not limited to, verification failure reasons, suggested measures for verification failure phenomena and the like.

Specifically, the proxy transaction request further includes the current transaction number corresponding to the transaction initiation account, and the processing method of the blockchain transaction may further include: the intelligent contract node obtains the historical transaction times of the transaction initiating account, compares the current transaction times with the historical transaction times, and performs the transaction of the first virtual token amount between the transaction initiating account and the transaction receiving account and performs the transaction of the second virtual token amount between the transaction initiating account and the proxy node based on the proxy transaction request if the current transaction times are matched with the historical transaction times; if the current transaction times are not matched with the historical transaction times, the non-passing information can be fed back and checked.

Specifically, the proxy transaction request further includes signature information of the transaction initiating account on the transaction content, and the processing method of the blockchain transaction may further include: the intelligent contract node determining target account information of the transaction initiation account based on the signature information; if the target account information matches the account information of the transaction initiation account, performing a transaction of the first virtual token amount between the transaction initiation account and the transaction receipt account and performing a transaction of the second virtual token amount between the transaction initiation account and the proxy node based on the proxy transaction request; if the target account information is inconsistent with the account information of the transaction initiating account, information that the verification fails can be fed back.

Wherein the smart contract node determines target account information of the transaction initiation account based on the signature information, and may include: the intelligent contract node can infer account information of a transaction initiating account corresponding to the signature information based on the signature information and transaction content corresponding to the signature information, namely, the target account information of the transaction initiating account is determined.

Illustratively, based on the above example, when the smart contract receives the proxy transaction request, the validity check may be performed on the sig based on the content transfer_by_paythestoken (a, B,90, 10, sig) in the proxy transaction request, and when the sig validity check passes, the smart contract node transfers 90 token na in account a to account B and transfers 10 token na in account a to the proxy node to serve as the proxy node to proxy the proxy fee of the transaction.

In some embodiments, since the first virtual token amount traded with the transaction receiving account may include a token amount transferred from the transaction initiating account to the transaction receiving account or a token amount obtained from the transaction receiving account, the manner in which the first virtual token amount is traded between the transaction initiating account and the transaction receiving account is correspondingly different.

Specifically, the first virtual token amount transacted with the transaction receipt account includes a token amount transferred from the transaction initiation account to the transaction receipt account, and the transaction of the first virtual token amount between the transaction initiation account and the transaction receipt account may include: the smart contract node transfers virtual tokens of the first virtual token amount in the transaction initiating account to the transaction receiving account.

Specifically, the first virtual token amount transacted with the transaction receipt account may include a token amount acquired from the transaction receipt account, and the transaction of the first virtual token amount between the transaction initiation account and the transaction receipt account may include: the smart contract node transfers virtual tokens of the first virtual token amount in the transaction receipt account to the transaction initiation account.

It will be appreciated that when the transaction initiating account and the transaction receiving account are held by different users and the transaction receiving account is to be transferred to the transaction initiating account for a virtual token amount, i.e. a first virtual token amount, but the transaction receiving account does not want to pay the primary token to the smart contract or to transfer the virtual token of a second virtual token amount to the agent node, the transaction initiating account may issue a transaction request to the agent node for the first virtual token amount in the transaction receiving account, i.e. the transaction initiating account pays the agent fee required by the agent node, i.e. the token of the second virtual token amount, to cause the agent node to issue an agent transaction request to the smart contract, causing the smart contract node to transfer the virtual token of the first virtual token amount in the transaction receiving account to the transaction initiating account based on the agent transaction request.

Wherein, because virtual token transfer is required from the transaction receiving account, in order to avoid that the transaction receiving account does not accept the transaction, before the proxy node generates the proxy transaction request based on the transaction request, the method may further include: the proxy node further includes, before generating a proxy transaction request based on the transaction request: the agent node generates an authorized agent request based on the transaction request, and transmits the authorized agent request to the transaction receiving account so that the transaction receiving account feeds back information based on the authorized agent request, wherein the transaction receiving account comprises account information of the transaction initiating account and the first virtual token amount. If the proxy node receives the agreement proxy information fed back by the transaction receiving account, the proxy node generates a proxy transaction request based on the transaction request; if the proxy node receives the disagreement proxy information fed back by the transaction receiving account, the proxy node can feed back related information to the transaction initiating account.

As can be seen from the above, a transaction request sent by a transaction initiation account is received by the agent node, wherein the transaction request includes transaction content, the transaction content including account information of a transaction receipt account, a first virtual token amount transacted with the transaction receipt account, and a second virtual token amount paid to the agent node; the agent node also generates an agent transaction request based on the transaction request, sends the agent transaction request to the smart contract node, and pays the smart contract node for the native tokens required to complete the agent transaction request, wherein the agent transaction request includes account information of the transaction initiating account and the transaction receiving account, the first virtual token amount, and the second virtual token amount; and finally, the intelligent contract node receives the proxy transaction request, and based on the proxy transaction request, the first virtual token amount is transacted between the transaction initiating account and the transaction receiving account, and the second virtual token amount is transacted between the transaction initiating account and the proxy node, so that under the condition that the transaction initiating account does not have the original token, the proxy node proxies the transaction initiating account to initiate the request to the intelligent contract node, so that the intelligent contract node is caused to conduct the blockchain transaction which the transaction initiating account wants to conduct based on the request, and the efficiency of the blockchain transaction of the account which does not hold the original token is improved.
