Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
In the embodiment of the service processing method and device based on the blockchain, a flowchart of the service processing method based on the blockchain is shown in fig. 1. In fig. 1, the service processing method based on the block chain includes the following steps:
step S01, the master node in the blockchain network acquires the service data sent by the user end through the wireless communication module and generates a block: the blockchain network comprises a plurality of nodes, and a plurality of clients can perform business interaction with the blockchain. The blockchain network may be a federation chain or a private chain, and is capable of providing business services to users. The node may be a server, a computer, a mobile terminal, or the like having a calculation processing function. In this step, the master node in the block chain network acquires the service data sent by the user side through the wireless communication module and generates a block.
In this step, the master node in the blockchain network node receives transaction request data sent by the user side through the wireless communication module, and packages the transactions into new blocks according to a preset sequence under the condition that the transactions corresponding to the transaction request data are verified to be valid, wherein the preset sequence represents the time sequence of the transactions. The user side can be a mobile phone or a tablet computer and the like.
The wireless communication module is any one or combination of any several of a 5G communication module, a 4G communication module, a Bluetooth module, a WiFi module, a GSM module, a CDMA2000 module, a WCDMA module, a TD-SCDMA module, a Zigbee module and an L oRa module, and by setting multiple wireless communication modes, the flexibility of the wireless communication modes can be improved, and the requirements of different users and different occasions can be met.
Each blockchain network node broadcasts a transaction request sent by a user terminal to the whole network, the main node firstly verifies a plurality of transactions needing to be placed in a new block collected from the blockchain network, and after the verification is passed, the transactions are sequenced according to a preset sequence and then packaged into the new block. The master node may be randomly chosen from the blockchain network nodes.
Step S02 the master node broadcasts the tile to all accounting nodes in the blockchain network: in this step, the broadcast makes the block chain network nodes participating in the consensus perform consensus on the blocks, and a consensus mechanism is adopted to send the result of whether the block chain network nodes participating in the accounting perform the block signature confirmation to all the block chain network nodes in the stage of confirmation of the consensus. After each block chain network node participating in consensus receives the blocks, the transactions are executed according to a plurality of transaction simulation models after the transactions are sequenced in the blocks, and after all transactions are executed, the hash value of a new block is calculated based on transaction results and is broadcasted to the whole network. I.e. the master node broadcasts the blocks to all accounting nodes in the blockchain network.
Step S03, the master node determines whether there are a set number of accounting nodes that can provide the verification service: in this step, the master node determines whether a set number of accounting nodes can provide the verification service, and if the determination result is yes, step S05 is executed; otherwise, step S04 is executed. The set number is 4/5 which is the total number of nodes in the blockchain network. Assuming that there are only 5 nodes in the blockchain network, dynamic fault tolerance cannot be achieved when there are only 5 summary points, so that one necessary submission of the fault tolerance upper limit is at least the number of nodes capable of providing service in the blockchain network. When the number of available nodes is less than 6, it can be determined that the fault tolerance threshold is reached, and actually, the system is in a crash state at this time, and cannot continue to process the service of the user side.
Step S04, determining that the fault-tolerant threshold of the current consensus mechanism is reached, terminating execution of the consensus mechanism, writing the block into a block chain after being encrypted by an encryption algorithm, and if the judgment result of the step S03 is negative, executing the step.
If the step S05 does not reach the fault tolerance threshold of the current consensus mechanism, the consensus mechanism is executed: if the judgment result of the above step S03 is yes, the present step is executed. In this step, if the fault tolerance threshold of the current consensus mechanism is not reached, the consensus mechanism is executed. The service processing method based on the block chain can avoid system crash when the block chain network reaches the fault-tolerant upper limit, and ensure the normal processing of user services.
The embodiment also relates to a device for implementing the service processing method based on the block chain, and a schematic structural diagram of the device is shown in fig. 2. In fig. 2, the apparatus includes a block generating module 1, a broadcasting module 2, a judging module 3, a fault tolerance threshold determining module 4 and a consensus mechanism executing module 5; the block generation module 1 is used for acquiring service data sent by a user terminal through a wireless communication module by a main node in a block chain network and generating a block; the user side is a mobile phone or a tablet computer; the blockchain network comprises a plurality of nodes, and a plurality of clients can perform business interaction with the blockchain. The blockchain network may be a federation chain or a private chain, and is capable of providing business services to users. The node may be a server, a computer, a mobile terminal, or the like having a calculation processing function. And the main node in the block chain network node receives transaction request data sent by the user side through the wireless communication module, and packages the transactions into a new block according to a preset sequence under the condition that the transactions corresponding to the transaction request data are verified to be valid, wherein the preset sequence represents the time sequence of the transactions. The user side can be a mobile phone or a tablet computer and the like.
The wireless communication module is any one or combination of any several of a 5G communication module, a 4G communication module, a Bluetooth module, a WiFi module, a GSM module, a CDMA2000 module, a WCDMA module, a TD-SCDMA module, a Zigbee module and an L oRa module, and by setting multiple wireless communication modes, the flexibility of the wireless communication modes can be improved, and the requirements of different users and different occasions can be met.
Each blockchain network node broadcasts a transaction request sent by a user terminal to the whole network, the main node firstly verifies a plurality of transactions needing to be placed in a new block collected from the blockchain network, and after the verification is passed, the transactions are sequenced according to a preset sequence and then packaged into the new block. The master node may be randomly chosen from the blockchain network nodes.
The broadcast module 2 is used for the main node to broadcast the block to all the accounting nodes in the block chain network; and broadcasting so that the block chain network nodes participating in the consensus know the blocks, and sending a result of whether the block chain network nodes participating in the accounting confirm the block signatures to all the block chain network nodes in a confirmation stage of the consensus by adopting a consensus mechanism. After each block chain network node participating in consensus receives the blocks, the transactions are executed according to a plurality of transaction simulation models after the transactions are sequenced in the blocks, and after all transactions are executed, the hash value of a new block is calculated based on transaction results and is broadcasted to the whole network. I.e. the master node broadcasts the blocks to all accounting nodes in the blockchain network.
The judging module 3 is used for the main node to judge whether the accounting nodes with the set number can provide the verification service; assuming that there are only 5 nodes in the blockchain network, dynamic fault tolerance cannot be achieved when there are only 5 summary points, so that one necessary submission of the fault tolerance upper limit is at least the number of nodes capable of providing service in the blockchain network. When the number of available nodes is less than 6, it can be determined that the fault tolerance threshold is reached, and actually, the system is in a crash state at this time, and cannot continue to process the service of the user side.
The fault-tolerant threshold determination module 4 is used for determining that a fault-tolerant threshold of the current consensus mechanism is reached, terminating execution of the consensus mechanism, and writing the block into a block chain after encryption by an encryption algorithm, thereby avoiding a situation that a system crashes and cannot process a user's request when a block chain network reaches a fault-tolerant upper limit.
In summary, in this embodiment, since the execution of the consensus mechanism is terminated when the fault-tolerant threshold of the current consensus mechanism is reached, the block is encrypted by the encryption algorithm and then written into the block chain; when the fault-tolerant threshold of the current consensus mechanism is not reached, the consensus mechanism can be continuously executed, so that system breakdown can be avoided when the block chain network reaches the fault-tolerant upper limit, and normal processing of user services is ensured.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
