While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 shows a flow chart of a method for verifying information in a blockchain network according to an embodiment of the present invention, as shown in fig. 1, the method specifically includes the following steps:
step S101, a first node in the block chain network monitors the information broadcast in the block chain network.
The information broadcast in the blockchain network comprises transaction information and block information. One or more transaction messages are included in the tile message. The first node is located in the network of the block chain and can monitor the transaction information and the block information broadcast in the network of the block chain.
And S102, the first node verifies the monitored information and judges whether the verification information is legal or not.
The first node can verify the legality of the monitored information according to preset verification conditions, and the legality of different information is verified differently correspondingly.
If the transaction information is validated legally, at least the following preset validation conditions are included: whether the syntax and data structure in the transaction information is correct, the transaction information input and output lists cannot be empty, the byte SIZE of the transaction must be less than a preset length threshold, e.g., MAX _ BLOCK _ SIZE, each output value and total amount in the transaction information must be within a specified range, e.g., greater than 0, less than 2100, no hash in the transaction information is equal to 0, N is equal to-1 for the input, the minimum time limit (nLockTime) in the transaction information is less than or equal to a preset threshold, e.g., INT _ MAX, the byte SIZE of the transaction is greater than or equal to 100, the number of signatures in the transaction is less than the upper limit of the number of signature operations, the unlock script must push the number onto the stack, and the lock script must conform to whether a standard format is present, one matching transaction in the transaction pool or in the main branch BLOCK must be present, for each transaction input, if the referenced output is present in any transaction in the transaction pool, the transaction is rejected, and for each transaction input, a referenced output transaction is found in the main branch and the transaction pool; if an outgoing transaction lacks any of the inputs, the transaction will become an isolated transaction; if the transaction matching it has not already appeared in the pool, it will be added to the isolated transaction pool, for each transaction input, if the referenced output transaction is a bitcoin (coin) output, the input must at least obtain a confirmation that the unlocking time of the bitcoin is 100, e.g. COINBASE _ MATURITY, for each transaction input, the referenced output must be present and not be spent, the input values are obtained using the referenced output transaction, and it is checked whether each input value and the total value are within a specified range of values, e.g. greater than 0 and less than 2100, if the sum of the input values is less than the sum of the output values, the transaction will be aborted, if the transaction cost is too low to enter an empty block, the transaction will be rejected, the unlocking script for each transaction input must be verified against the corresponding output locking script, etc.
If the block is validated, the validation conditions at least include the following preset validation conditions: the data structure of the block is syntactically valid, the hash value of the block header is less than the target difficulty to confirm that sufficient workload declaration is contained, the block timestamp is two hours into the future earlier than the verification time, the block size is within the length limit, the first transaction of the block and only the first is a bitcoin (coin) transaction, the transactions within the block are verified using the checklist and their validity is ensured, and the transaction verification can refer to the validity verification of the above transactions.
The first node verifies the monitored information, and if the verification information is judged to be legal, the step S103 is continuously executed.
Step S103, if the verification information is legal information, the first node signs the information.
After the first node verifies that the information is legal, the first node signs the information by using the first node private key, namely the first node can sign the transaction information or sign the block information by using the first node private key.
The implementation process of the specific signature can be implemented in a manner of using hash in the private key encryption information as the signature, and is not specifically limited herein.
And step S104, the first node stores the signed information and forwards the signed information.
When the first node stores the signed information, different information storage modes are different. If the transaction information exists, the first node stores the transaction information into a memory pool of the first node, and then forwards the signed transaction information. As with the block information, the first node synchronizes the block information into the first node's blockchain and then forwards the signed block information.
And step S105, the second node in the block chain network receives the signed information, verifies the information and judges whether the verification is passed.
The second node, that is, other nodes in the blockchain network except the first node, are all second nodes, and the information received by the second node is signed information.
And after receiving the signed information, the second node verifies whether the signature of the information is the signature of the first node by using the public key of the first node. The specific verification process may be implemented by, for example, decrypting the signature by using the first node public key, and verifying whether the decrypted hash is consistent with the original text, which is not specifically limited herein.
If the signature of the verification information is the signature of the first node, that is, the information is verified to be legitimate by the first node, and the verification information is legitimate, the process continues to execute step S106.
And step S106, if the verification is passed, the second node signs the information for the second time.
The second node does not verify the validity of the information, but signs the information for the second time on the basis of the signature of the first node, or signs the information for the second time to replace the signature of the first node. And during secondary signature, the second node signs the transaction information or the block information by using a second node private key.
And step S107, the second node stores the information after the secondary signature and forwards the information after the secondary signature.
And after secondary signature, the second node stores the information subjected to secondary signature, and different information storage modes are different. If the transaction information exists, the second node stores the transaction information into a memory pool of the second node, and then forwards the transaction information after the secondary signature. If the block information exists, the second node synchronizes the block information to the block chain of the second node and forwards the block information after secondary signature.
According to the verification method of the information in the block chain network, which is provided by the invention, the first node in the block chain network monitors the information broadcast in the block chain network and verifies the monitored information. And after the information is verified to be legal, the first node signs the information. And storing the signed information and forwarding the signed information. And the second node positioned in the block chain network receives the signed information and verifies the information. And if the verification is passed, the second node carries out secondary signature on the information. And storing the information after the secondary signature, and forwarding the information after the secondary signature. The information is not required to be legally verified by all the nodes, the workload of verifying the information by partial nodes is reduced, the information forwarding speed is accelerated, and the information can be forwarded more quickly.
Fig. 2 is a flowchart illustrating a method for verifying information in a blockchain network according to another embodiment of the present invention, where as shown in fig. 2, the method specifically includes the following steps:
step S201, a first node in the blockchain network monitors information broadcast in the blockchain network.
Step S202, the first node verifies the monitored information and judges whether the verification information is legal or not.
The above steps can refer to steps S101 and S102 in the embodiment of the method in fig. 1, and are not described herein again.
It should be noted that, in step S202, the first node verifies the monitored information, and if the verification information is determined to be legitimate, step S203 is continuously executed, and if the verification information is determined to be illegitimate, step S208 is executed.
In step S203, if the verification information is legal, the first node generates a signature message for the information.
And after verifying that the information is legal, the first node generates a signature message for the information. If the information is transaction information, the signature message comprises the hash of the transaction information content and the signature of the node on the transaction information content. If the information is the block information, the signature message comprises the hash of the block information content and the signature of the node on the block information content. The signature of the transaction information content or the signature of the block information content is the signature of the transaction information content or the signature of the block information content by the first node by using the first node private key.
And step S204, the first node stores the information and respectively forwards the information and the signature message.
When the first node stores the information, different information storage modes are different. If the transaction information exists, the first node stores the transaction information into a memory pool of the first node, and then forwards the signed transaction information. For example, the first node synchronizes the block information to the block chain of the first node, and then forwards the signed block information.
Step S205, the second node in the blockchain network receives the information and the signature message, verifies the information and the signature message, and determines whether the verification passes.
The second node, that is, other nodes in the blockchain network except the first node, are the second node.
And after the second node receives the information and the signature message, if the information is the transaction information, the hash of the transaction content is obtained from the signature message of the information, and the corresponding transaction information content is obtained. When the transaction information is verified, the validity of the transaction information content can be verified, the signature of the transaction information content can also be verified, and whether the signature of the transaction information content is the signature of the first node is verified by using the first node public key. And if the information is the block information, acquiring the hash of the block information content from the signature message of the information to obtain the corresponding block information content. When the block information is verified, the validity of the block information content can be verified, and the signature of the block information content can also be verified. And verifying whether the signature of the block information content is the signature of the first node by using the public key of the first node.
If the verification is passed, that is, the information has been legally verified by the first node, and the verification information is legal, the step S206 is continuously executed, otherwise, the step S208 is executed.
And step S206, if the verification is passed, the second node signs the information for the second time.
And step S207, the second node stores the information after the secondary signature and forwards the information after the secondary signature.
The above steps can refer to steps S106 and S107 in the embodiment of the method in fig. 1, and are not described herein again.
In step S208, the information is discarded.
And directly discarding the information about whether the first node verifies the information is legal and failed and the information about whether the second node verifies the signature of the non-first node, namely the information is illegal or the signature is possibly a forged signature.
According to the method for verifying the information in the block chain network, provided by the invention, if the monitored information is verified to be legal information by the first node, a signature message is generated for the information. And storing the signed information and forwarding the signed information. Otherwise, the information is discarded directly. And if the signed information passes the verification of the second node, performing secondary signature on the information. And storing the information after the secondary signature, and forwarding the information after the secondary signature. Otherwise, the information is discarded directly. The workload of partial node verification information is reduced, the information forwarding speed is increased, and the information can be forwarded more quickly. Meanwhile, the information which fails to pass the verification, namely the illegal information or the information of the forged signature is directly discarded, so that the workload of information verification is reduced.
Fig. 3 is a functional structure diagram of a system for verifying information in a blockchain network according to an embodiment of the present invention, and as shown in fig. 3, the system includes the following nodes:
the first node 310 is configured to listen to information broadcast in the blockchain network; verifying the monitored information; if the verification information is legal information, signing the information; and storing the signed information and forwarding the signed information.
The information broadcast in the blockchain network comprises transaction information and block information. One or more transaction messages are included in the tile message. The first node 310 is located in a network of a block chain, and can monitor transaction information and block information broadcast in the network of the block chain. The first node 310 performs validity verification on the monitored information according to a preset verification condition, where the validity verification is different for different information. The preset verification condition may refer to the step S102 in the method embodiment, and is not described herein again. The first node 310 verifies the monitored information according to the information type, and if the verified information is legal information, the first node 310 signs the information by using the first node private key, that is, the first node 310 may sign the transaction information or sign the block information by using the first node private key. The first node 310 stores the signed information, and different information storage methods are different. If the transaction information is received, the first node 310 stores the transaction information in the first node memory pool, and then forwards the signed transaction information. As block information, the first node 310 synchronizes the block information into the first node block chain and then forwards the signed block information.
The second node 320 is configured to receive the signed information and verify the information; if the verification is passed, carrying out secondary signature on the information; and storing the information after the secondary signature, and forwarding the information after the secondary signature.
Here, the second node 320, i.e. other nodes in the blockchain network except the first node 310, are all the second nodes 320, and the information received by the second node 320 is signed information.
After receiving the signed information, the second node 320 verifies whether the signature of the information is the signature of the first node by using the public key of the first node. The specific verification process may be implemented, for example, by decrypting the signature with the first node public key, and verifying whether the decrypted hash is consistent with the original text, which is not specifically limited herein. If the signature of the information verified by the second node 320 is the signature of the first node, that is, the information is verified to be legitimate by the first node 310, and the verified information is legitimate, the second node 320 does not verify the legitimacy of the information any more, but performs a secondary signature on the information on the basis of the signature of the first node 310, or performs a secondary signature on the information to replace the signature of the first node. During the second signature, the second node 320 uses the second node private key to sign the transaction information or the block information. After the second signature, the second node 320 stores the information after the second signature, and different information storage modes are different. If the transaction information is received, the second node 320 stores the transaction information in the memory pool of the second node, and then forwards the transaction information after the secondary signature. For example, the second node 320 synchronizes the block information to the second node block chain and forwards the block information after the secondary signature.
Further, the first node 310 verifies the monitored information, and if the verified information is judged to be illegal, the information is directly discarded, so that the information is not broadcasted in the blockchain network. The first node 310 signing the information may also include generating a signature message for the information. If the information is transaction information, the signature message comprises the hash of the transaction information content and the signature of the node on the transaction information content. If the information is the block information, the signature message comprises the hash of the block information content and the signature of the node on the block information content. The signature of the transaction information content or the signature of the block information content is the signature of the transaction information content or the signature of the block information content by the first node 310 by using the first node private key.
Accordingly, if the first node 310 generates a signature message for the information, the verification of the information by the second node 320 further comprises: if the information is transaction information, the second node 320 obtains the hash of the transaction content from the signature message of the information to obtain the corresponding transaction information content. When verifying the transaction information, the second node 320 may verify the validity of the transaction information content, and may also verify the signature of the transaction information content, and verify whether the signature of the transaction information content is the signature of the first node by using the public key of the first node. If the information is the block information, the second node 320 obtains the hash of the block information content from the signature message of the information to obtain the corresponding block information content. When verifying the block information, the second node 320 may verify the validity of the content of the block information, and may also verify the signature of the content of the block information. And verifying whether the signature of the block information content is the signature of the first node by using the public key of the first node. If the second node 320 fails the verification, the second node 320 directly discards the information and does not have it broadcast in the blockchain network again.
According to the verification system for the information in the block chain network, which is provided by the invention, the first node in the block chain network is used for monitoring the information broadcast in the block chain network and verifying the monitored information. And after the information is verified to be legal, the first node signs the information. And storing the signed information and forwarding the signed information. And the second node positioned in the block chain network receives the signed information and verifies the information. And if the verification is passed, the second node carries out secondary signature on the information. And storing the information after the secondary signature, and forwarding the information after the secondary signature. The information is not required to be legally verified by all the nodes, the workload of verifying the information by partial nodes is reduced, the information forwarding speed is accelerated, and the information can be forwarded more quickly. Meanwhile, the information which fails to pass the verification, namely the illegal information or the information of the pseudo-signature is directly discarded, so that the workload of information verification is reduced.
