As shown in fig. 1, the transaction information verification method in the embodiment of the application includes the following steps S11 to S14:
in step S11, performing identification operation on a target endorsement node in the blockchain;
in step S12, under the condition that the transaction information is received, performing a preset process on the transaction information, where the preset process is used to enable the transaction information to be added with consensus information by the target endorsement node;
in step S13, broadcasting the transaction information after the preset processing in the blockchain;
in step S14, in the case where the consensus information returned by the target endorsement node for the transaction information is received, an operation corresponding to the consensus information is performed.
In the embodiment, the identification operation is performed on the target endorsement node in the blockchain; the identification operation is performed by the submitting node.
Specifically, a preset attribute and a common parameter of a preset type are sent to a submitting node in a blockchain, so that the submitting node screens target endorsement nodes with the preset attribute in the blockchain, and then the common parameter of the preset type is sent to the target endorsement nodes, so that only the target endorsement nodes with the preset attribute have authority to endorse transaction information.
Under the condition that transaction information is received, carrying out preset processing on the transaction information, wherein the preset processing is used for enabling the transaction information to be added with consensus information by a target endorsement node;
specifically, the target policy may be generated based on the preset attribute, and then the transaction information is encrypted based on the target policy and the information related to the common parameter together, so as to form encrypted transaction information.
Broadcasting the transaction information after the preset processing in a block chain;
after the transaction information is broadcast in the blockchain, all endorsement nodes can see the broadcast, but because the transaction information is encrypted based on the information related to the target strategy and the public parameters, the transaction information can be identified only by the endorsement node which needs to meet the target strategy and can decrypt the transaction information, and the target endorsement nodes all contain the preset attribute, so that the target strategy generated based on the preset attribute can be met, and the target endorsement nodes all receive the public parameters sent by the submitting node and can decrypt the transaction information, so that the target endorsement node has authority to endorse the transaction information, and other endorsement nodes cannot decrypt and do not meet the target strategy, therefore, the endorsement of the transaction information cannot be carried out, the specific content of the transaction information cannot be seen, the transaction information is prevented from being leaked to unsafe endorsement nodes, the probability of the endorsement node leaking the transaction information is reduced, and the security of the transaction information is improved.
And executing the operation corresponding to the consensus information under the condition that the consensus information returned by the target endorsement node for the transaction information is received.
It will be appreciated that: the transactions referred to in this application relate to data exchange in a blockchain, one embodiment of which is as follows:
the client submits a data transfer application to a submitting node, for example, the data of the client is transferred to another client (the data can be data corresponding to encrypted currency or other types of data), the submitting node performs whole-network broadcasting to endorsement nodes in the blockchain, then the endorsement nodes verify transaction information, the verification result is fed back to the submitting node, the submitting node performs subsequent processing based on the verification result, for example, when the verification is passed, the submitting node performs in-chain operation on the transaction information, namely, anchors the transaction on the blockchain, when the verification is not passed, the data transfer application proposed by the client is refused, and prompt information which is not passed is fed back to the client. Thus, the transaction corresponding to the transaction information mentioned in the present application is essentially an information interaction and processing procedure.
The beneficial effects of this application lie in: performing identification operation on a target endorsement node in the block chain; under the condition of receiving the transaction information, carrying out preset processing on the transaction information, so that the transaction information can only be added with consensus information by the endorsement node after the identification operation; and the endorsement node which does not perform the identification operation cannot add the consensus information to the endorsement node, so that the transaction information is prevented from being leaked to the unsafe endorsement node, the probability of the endorsement node to leak the transaction information is reduced, and the security of the transaction information is improved.
In one embodiment, the step S11 may be implemented as the following steps:
and sending the preset attribute and the preset type common parameter to a submitting node in the blockchain, wherein the submitting node is used for acquiring an endorsement node with the preset attribute in the blockchain as a target endorsement node and sending the preset type common parameter to the target endorsement node in the blockchain.
For example, the preset attribute and the common parameter of the preset type are sent locally to the submitting node in the blockchain, for example, the preset attribute may be an endorsement server of an endorsement mechanism capable of characterizing that the endorsement node is international authentication or multi-country joint authentication, for example, the preset attribute may be an international authentication identifier, then, the endorsement node with the international authentication identifier is a target endorsement node, only the target endorsement node with the international authentication identifier is selected by the submitting node, and the common parameter for decryption is sent to the target endorsement node.
In one embodiment, the preset processing of the transaction information in the step S12 may be implemented as the following steps S21-S22:
in step S21, a target policy is generated based on the preset attribute;
in step S22, the transaction information is encrypted based on the target policy and the information related to the common parameter together to form encrypted transaction information.
For example, assuming that the preset attribute is an international authentication identifier, the target policy generated based on the preset attribute may be an endorsement node having the international authentication identifier as an endorsement node meeting the condition, and, of course, the target policy may be further defined on this basis, for example, the endorsement node needs to have the international authentication identifier and also needs to be located in a specific country, so that the endorsement node may be further screened, of course, the target policy may be further defined, or a plurality of conditions may be set to be in a relation, so long as the endorsement node can meet one of the conditions, and the target policy may be freely set according to a specific situation, which is not described herein.
After the target policy is generated, encrypting the transaction information based on the target policy and the information related to the public parameters together to form encrypted transaction information, for example, after the encryption of the public parameters, adding the target policy into the transaction information, which is equivalent to secondary encryption, when the endorsement node is successful in decryption, matching is required to be performed based on the target policy and the attribute set of the endorsement node, if the matching is successful, the transaction information can be endorsed, and if the matching is unsuccessful, the endorsement cannot be performed.
In one embodiment, the encrypted transaction information allows endorsement nodes that are able to decrypt it and meet the target policy to add consensus information.
In this embodiment, the encrypted transaction information allows the endorsement node capable of decrypting the transaction information and meeting the target policy to add the consensus information, and the target endorsement nodes all contain the preset attribute, so that the target policy generated based on the preset attribute can be met, and the target endorsement nodes all receive the public parameters sent by the submitting node and can decrypt the transaction information, so that the target endorsement node has authority to endorse the transaction information, and other endorsement nodes cannot decrypt the transaction information and do not meet the target policy, so that the endorsement cannot endorse the transaction information and cannot see the specific content of the transaction information, the transaction information is prevented from being leaked to unsafe endorsement nodes, the probability of the endorsement node leaking the transaction information is reduced, and the security of the transaction information is improved.
In one embodiment, the consensus information includes a signature packet and a hint that the verification failed;
the operation performed in the above-described step S14 corresponding to the identification information may be implemented as the following steps A1 to A4:
in step A1, receiving a signature data packet returned by an endorsement node aiming at transaction information and/or prompt information of verification failure;
in step A2, judging whether the transaction meets preset conditions according to the signature data packet and/or prompt information of verification failure;
in step A3, under the condition that the transaction meets the preset condition, recording the transaction in the blockchain;
in step A4, if the transaction does not meet the preset condition, a prompt message of transaction failure is sent to the party initiating the transaction corresponding to the transaction information.
In the embodiment, receiving a signature data packet returned by an endorsement node aiming at transaction information and/or prompt information of verification failure; specifically, it is assumed that 10 endorsement nodes endorse transaction information, wherein 7 endorsement nodes verify that the transaction corresponding to the transaction information is legal, so that the 7 endorsement nodes generate a signature data packet, and the other 3 endorsement nodes verify that the transaction corresponding to the transaction information is illegal, and the 3 endorsement nodes return prompt information of failure in verification. Judging whether the transaction meets preset conditions according to the signature data packet and/or prompt information of verification failure; assuming that the preset condition is that the transaction is legal when the ratio of the number of signature data packets to the total number of endorsement nodes is greater than or equal to 60%, in the above example, the ratio of the number of signature data packets to the total number of endorsement nodes is 70%, and thus the transaction meets the preset condition, the transaction is recorded in the blockchain; and under the condition that the transaction does not accord with the preset condition, sending prompt information of transaction failure to a transaction initiating party corresponding to the transaction information. It should be understood that the transaction referred to herein refers to a transaction corresponding to the transaction information described in the present application.
In one embodiment, the above step A2 may be implemented as steps B1-B4 as follows:
in the step B1, receiving a signature data packet returned by an endorsement node aiming at transaction information and/or prompt information of verification failure;
in step B2, determining the number of endorsement nodes that transmit the consensus information;
in step B3, judging whether the ratio of the number of the received signature data packets to the number of endorsement nodes sending the consensus information reaches a preset ratio;
in step B4, when the ratio of the number of received signature data packets to the number of endorsement nodes transmitting the consensus information reaches a preset ratio, it is determined that the transaction meets a preset condition.
In the embodiment, receiving a signature data packet returned by an endorsement node aiming at transaction information and/or prompt information of verification failure; determining the number of endorsement nodes transmitting the consensus information; judging whether the ratio of the number of the received signature data packets to the number of endorsement nodes sending the consensus information reaches a preset ratio or not; and under the condition that the ratio of the number of the received signature data packets to the number of the endorsement nodes sending the consensus information reaches a preset ratio, determining that the transaction meets the preset condition.
For example, assuming that the preset proportion is 60%, there are 10 endorsement nodes that send the consensus information, wherein 7 endorsement nodes verify that the transaction corresponding to the transaction information is legal, so that the 7 endorsement nodes want to locally send signature data packets, and the other 3 endorsement nodes verify that the transaction corresponding to the transaction information is illegal, and the 3 endorsement nodes return prompt information of verification failure. The ratio of the number of the received signature data packets to the number of the endorsement nodes transmitting the consensus information is 70%, and the preset ratio is reached, so that the transaction meets the preset condition.
In addition, it is understood that the signature data packet and/or the prompt information of verification failure in the present application refers to that the present application may only receive the signature data packet and not receive the prompt information of verification failure, or only receive the prompt information of verification failure and not receive the signature data packet, or receive both the signature data packet and the prompt information of verification failure. For example, 10 endorsement nodes send consensus information, and if the 10 endorsement nodes pass the verification result of the transaction information, only 10 signature data packets are locally received, and no prompt information of verification failure exists. If the verification result of 7 nodes on the transaction information is passed and the verification result of 3 endorsement nodes on the transaction information is failed in the 10 nodes, 7 signature data packets and 3 prompt messages of verification failure are received locally. If the 10 endorsement nodes fail to verify the transaction information, only 10 prompt messages with failed verification are received locally, and no signature data packet exists.
The beneficial effects of this embodiment lie in: under the condition that the ratio of the number of the received signature data packets to the number of the endorsement nodes sending the consensus information reaches a preset ratio, the transaction is determined to accord with the preset condition, so that all endorsement nodes participating in the consensus are not required to return the signature data packets, the transaction is also determined to accord with the preset condition, malicious endorsement of unsafe endorsement nodes still exist in the endorsement nodes participating in the consensus, and the accuracy of transaction information verification is improved.
In one embodiment, the above step A2 may be implemented as the following steps C1-C3:
in step C1, receiving a signature data packet returned by an endorsement node for transaction information and/or prompt information of verification failure;
in step C2, judging whether the number of the received signature data packets reaches a preset number;
in step C3, when the number of received signature data packets reaches the preset number, it is determined that the transaction meets the preset condition.
For example, assuming that the preset number is 3, after receiving the signature data packet returned by the endorsement node for the transaction information and/or the prompt information of verification failure, counting whether the number in the signature data packet is greater than or equal to 3, if so, determining that the transaction meets the preset condition, and if not, if so, determining that the transaction meets the preset condition.
