The blockchain system is a distributed system placed in an insecure environment, all nodes in the blockchain system can perform distributed storage on the same data/block, the stored content of each node is the same, no central node is arranged in the blockchain system (namely decentralized), and the nodes can directly interact with each other.
2. The block chain system adopts a cryptographic method to ensure that data in the block chain is not tampered, and the cryptographic method used in the block chain system mainly comprises a hash (hash) function and an asymmetric encryption technology, wherein the hash function is used for verifying the integrity of information, and the asymmetric encryption technology is used for information encryption and identity verification. In the blockchain system, the service information is written in the blocks, the blockchain formed by the blocks can start from the second block as shown in fig. 4, each block contains the hash value of all the blocks before the block, the blocks stored in the blockchain system are chained together according to the generation time, and each data in the blocks has the digital signature of the initiator to ensure the authenticity and the validity.
3. The blockchain system adopts a consensus algorithm to achieve consensus on the newly added data, so that all nodes in the blockchain system achieve consensus on the newly added block in the blockchain system, i.e. the newly added block is approved. Based on a few majority-compliant principles, nodes in the blockchain system will recognize the latest data/blocks that are subject to consensus and update synchronously, wherein the consensus algorithms include, but are not limited to, Proof of workload (PoW) algorithm, Proof of rights (PoS) algorithm, granted Proof of rights (DPoS) algorithm, Practical Byzantine Fault Tolerance (PBFT) algorithm, and so on.
Based on the principle, the blockchain system performs distributed storage on the data, and once the information which is confirmed by the consensus of each node is stored in the blockchain system, the information cannot be tampered.

In this embodiment, as shown in fig. 3, the blockchain system may include a plurality of blockchain processing devices, where the plurality of blockchain processing devices include, but are not limited to, a first service settlement device, a second service settlement device, and a third service settlement device in this embodiment.
The specific process of the second service settlement device issuing the first settlement transaction to the blockchain system may be as shown in fig. 7, and the specific process is as follows:
s3031, the second service clearing device sends the first settlement transaction to the current blockchain management device in the blockchain system, and the blockchain management device receives the first settlement transaction.
Here, the blockchain management device (leader) is a blockchain processing device selected by all blockchain processing devices in the blockchain system based on a consensus mechanism in the blockchain system for packing the transactions that are not yet packed and are currently generated in the blockchain system, and all blockchain processing devices in the blockchain system select the blockchain management device according to a certain period. The block chain management device may be any one of the block chain processing devices in the block chain system, and for example, the block management device may be a first service settlement device, a second service settlement device, a third service settlement device, or a block chain processing device in the block chain system other than the first service settlement device, the second service settlement device, and the third service settlement device.
Optionally, when the current blockchain management device in the blockchain system is the second service clearing device, the blockchain management device directly performs step S3032, that is, when the second service clearing device generates the first settlement transaction, the second service clearing device directly performs transaction verification on the first settlement transaction.
S3032, the block chain management apparatus performs a transaction check on the first resultant transaction.
Here, the blockchain management apparatus verifies the transaction data structure of the first settlement transaction, the signature information of the first settlement transaction, and the like.
In the case where the transaction check on the first resultant transaction passes, the block chain management apparatus performs step S3033.
S3033, the blockchain management device sends the first transaction to other blockchain processing devices in the blockchain system, and the other blockchain processing devices receive the first transaction.
Here, the other blockchain processing device refers to a blockchain processing device other than the blockchain management device in the blockchain system, and for example, the blockchain system includes a first service settlement device, a second service settlement device, a third service settlement device, and a first blockchain processing device, and if the current blockchain management device is the first service settlement device, the other blockchain processing device is the first service settlement device, the third service settlement device, and the first blockchain processing device.
S3034, the other block chain processing device performs transaction check on the first calculation transaction.
Specifically, the other blockchain processing device checks the transaction data structure of the first transaction, the signature information of the first transaction, and the like.
S3035, the other block chain processing device sends a first transaction verification result obtained by performing transaction verification on the first calculation transaction to the block chain management device, and the block chain management device receives the first transaction verification result.
After receiving all the first transaction verification results sent by the other blockchain management devices, the blockchain management device determines whether the first calculated transaction passes the verification of the blockchain system according to a transaction verification result obtained by performing transaction verification on the first calculated transaction by all blockchain processing devices (here, the blockchain management device and the other blockchain devices) in the blockchain system on the basis of a minority-majority principle.
Specifically, when a transaction verification result obtained by performing transaction verification on the first calculation transaction by the most part of the blockchain processing devices in the blockchain system passes, the blockchain management device determines that the first calculation transaction passes through verification of the blockchain system; and under the condition that a transaction checking result obtained by the majority of blockchain processing devices in the blockchain system performing transaction checking on the first calculation transaction is invalid, the blockchain management device determines that the first calculation transaction is not checked by the blockchain system.
For example, there are 10 blockchain processing devices in the blockchain system, if all transaction verification results obtained by performing transaction verification on the first calculated transaction by 8 blockchain processing devices of the 10 blockchain processing devices pass, the blockchain management device determines that the first calculated transaction passes verification of the blockchain system, and if all transaction verification results obtained by performing transaction verification on the first calculated transaction by 6 blockchain processing devices of the 10 blockchain processing devices do not pass, the blockchain management device determines that the first calculated transaction does not pass verification of the blockchain system.
For another example, a PBFT algorithm is adopted in the block chain system to achieve consensus on the newly added data, and the judgment principle of the PBFT algorithm is as follows: the total number of the nodes is greater than or equal to 3f +1, if the voting result of 2f +1 nodes in the 3f +1 nodes is passed, the voting result is judged to be passed, otherwise, the voting result is judged not to be passed. Assuming that the block chain has 10 block chain processing devices in total, if the transaction verification results obtained by verifying the first result transaction by more than 7 block chain processing devices in the 10 block chain processing devices are all passed, the block chain management device determines that the first result transaction passes the verification of the block chain system, otherwise, the block chain management device determines that the first result transaction does not pass the verification of the block chain system.
It should be noted that the above example is only used for explaining that the blockchain management device determines whether the first resultant transaction passes the check of the blockchain system according to the transaction check result obtained by performing the transaction check on the first resultant transaction by all the blockchain processing devices in the blockchain system based on the principle of the minority majority based on the minority majority, and in an alternative embodiment, the blockchain management device may also determine whether the first resultant transaction passes the check of the blockchain system according to another consensus algorithm based on the minority majority, which is not limited in this application.
In the case that the first resultant transaction passes the verification of the blockchain system, the blockchain management device performs step S3036.
S3036, the block chain management apparatus constructs a second block corresponding to the first calculation transaction.
Here, the blockchain management device packs all the transactions which are generated in the blockchain system and are not packed yet, and constructs and forms a second block, wherein all the transactions which are not packed include the first settlement transaction.
S3037, the blockchain device sends the second block to other blockchain processing devices in the blockchain system, and the other blockchain processing devices receive the second block.
S3038, the other block chain processing device checks the second block.
S3039, the other blockchain processing device sends a check response to the blockchain management device according to the check result of the second block, and the blockchain management device receives the check response.
After receiving all the check responses sent by the other blockchain management devices, the blockchain management device determines whether the first calculated transaction passes the check of the blockchain system according to the check result of the second block checked by all the blockchain processing devices (here, the blockchain management device and the other blockchain devices) in the blockchain system on the basis of a minority-majority principle.
Specifically, when the result of checking the second block by the majority of blockchain processing devices in the blockchain system is that the second block passes, the blockchain management device determines that the second block passes the checking of the blockchain system; in the case where the result of checking the second block by the majority of the blockchain processing devices in the blockchain system is non-pass, the blockchain management device determines that the second block does not pass the checking of the blockchain system.
In the case that the second block passes the verification of the blockchain system, the blockchain management device performs step S30310.
S30310, the blockchain management device sends a first saving instruction to the other blockchain processing device, and the other blockchain processing device receives the first saving instruction, where the first saving instruction is used to instruct the other blockchain processing device to save the second block.
S30311, all the blockchain processing devices in the blockchain system store the second block.
