Background
The block chain technique is also called a distributed ledger technique, and is a decentralized distributed internet database in nature. A network using the blockchain technology architecture can be regarded as a blockchain network, and the blockchain network includes a plurality of blockchain nodes, where any blockchain node may correspond to at least one blockchain, and any blockchain may include at least one block.
There are transactions and states in the blockchain, and there are sets of multiple transactions in each block. After each new transaction in the block chain is processed, a set of data containing the determined current world state, namely a state root, is generated under the participation of a plurality of nodes, and the state root representing the world state is restored in the block.
In the current blockchain algorithm processing, each transaction is broadcasted to other participating nodes on the blockchain after being processed, and the other nodes on the blockchain are required to participate in the consensus algorithm together, and the sequencing is performed through the timestamp to determine which node verifies the transaction. After the transactions are identified and sorted, it is necessary to wait for the nodes to process all the transactions, calculate the last state root, and write the state root back to the block. Therefore, the consensus calculation and the state root calculation of each transaction processing are performed in time sequence, and particularly, when a plurality of transactions are processed simultaneously, the calculation processing is time-consuming.
The above is a synchronization process, and if the uplink calculation and the status calculation are separated into independent processes and communicated with each other through messages, the calculation efficiency may be greatly improved. Therefore, it is desirable to find a new uplink and status handling method based on block chains to overcome the above problems.

Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more apparent, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to specific embodiments of the present disclosure and corresponding drawings. It is to be understood that the embodiments described are only a few embodiments of the present disclosure, and not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present specification without making any creative effort belong to the protection scope of the embodiments in the present specification.
The technical solutions provided by the embodiments of the present description are described in detail below with reference to the accompanying drawings.
It should be noted that, in the embodiment of the present specification, the uplink and the state processing of the block chain are divided into a chain process and an executor process, which are independent of each other; the chain process sends the transaction information to the executor process through the transaction distribution process, executes the block uplink process, processes the transaction information through the state root calculation process to obtain the state root, returns the state root to the chain process, and stores the state root in the block to complete the block uplink process, so that the block uplink and the state root are calculated and separated, the efficiency of transaction processing and block uplink in the block chain can be effectively improved, and the calculation resources are saved.
Example one
Referring to fig. 1, a schematic diagram of a block chain-based uplink and status processing method provided in an embodiment of the present disclosure is shown, where the block chain-based uplink and status processing method in this embodiment includes:
a chain process 101 and an executor process 102; the chain process 101 includes a transaction distribution process 104 and a block uplink process 103, and the executor process 102 includes a contract process 105 and a state root computation process 106.
The chain process 101 and the executor 102 processes each independently and communicate with each other.
According to the uplink and status processing method based on a block chain in this embodiment, when a new transaction is generated on a block chain, the chain process 101 executes a transaction distribution process 104, and in the process of executing the transaction distribution process 104, transaction information is sent to the executor process 102, and the status root calculation process 106 processes the transaction information to obtain a status root (status _ root), and returns the status root to the chain process 101, and stores the status root in a block to complete the uplink block process.
In this embodiment, the link process 101 executes the transaction distribution process 104 while the block uplink process 103 is running simultaneously. Specifically, the block uplink process 103 includes a node handoff block request, each node generates a new block through a consensus algorithm, processes transaction data and generates a block hash value, and adds the block hash value and the new block to a block chain, thereby completing a new block uplink process.
In this embodiment, while the block uplink process 103 is executed, the chain process 101 executes the transaction distribution process 104 to send transaction information to the executor process 102.
In the existing block chain system composed of multiple nodes, a large number of nodes complete the consensus mechanism of new transaction uplink through the workload certification mechanism, which consumes a large amount of computing resources, and as a result, the block uplink is completed at the highest computing speed, which results in a large amount of computing resources being wasted.
In addition, after the consensus mechanism is completed, it is necessary to process the transaction information with a large amount of computation to obtain a state root (state _ root) representing all transaction information, so as to complete the block uplink.
According to the method provided in this embodiment, since the block uplink process 103 and the state root calculation process 106 are separately executed, each node on the node network may process the block uplink process 103 and the state root calculation process 106 in batch or separately, for example, some nodes process the block uplink process 103 exclusively, and perform common identification calculation of workload identification, or other nodes process transaction data to complete the state root calculation, and finally the fastest node obtains the right to perform uplink operation, and simultaneously invokes the execution result of the state root calculation process 106 from other nodes to complete block uplink. Therefore, a single node does not need to consume computation power in the uplink block procedure 103 and the state root computation procedure 106, and the computation speed can be greatly increased for the whole block chain by using the method provided by the embodiment.
It should be noted that, in this embodiment, the executor process 102 further includes a contract flow 105, and the contract flow 105 performs intelligent contract execution on the transaction data provided by the chain process 101, that is, multiple nodes perform a digital signature verification procedure at the same time, so as to ensure the validity of the transaction.
Specifically, in the present embodiment, since the contract process 105 is separated from the block uplink process 103, i.e. the digital signature verification process is separated from the block uplink process, the efficiency of information processing is further improved. For example, some nodes in the node network may be configured to perform the block uplink process 103, and another part may be configured to handle the contract process 105, and the function of verifying the contract validity may also be achieved.
Therefore, according to the method provided in this embodiment, the block uplink process 103 and the status root calculation process 106 are processed separately, and multiple nodes perform intelligent contract verification and participate in status root calculation while performing the block uplink process 103.
When a user performs an electronic money transaction such as a bitcoin, tens of thousands of transactions are often performed in the same section in the entire block chain. In a conventional block uplink mode, after receiving more than thousands of transaction information, a plurality of nodes usually perform intelligent contracts and block uplink on the transaction data together. While each node processes a large amount of transaction data, the joint calculation of the workload certification is also completed, and by adopting the method provided by the embodiment, for a large amount of transactions, the node network can process in batches and in a classified manner, and a large amount of nodes in the node network are respectively corresponding to different calculation processes, so that the calculation efficiency is improved.
Therefore, when multiple transactions are simultaneously carried out on the block chain, the efficiency of transaction processing and block chain linking in the block chain can be effectively improved, the computing resources are saved, and the time for block chain linking is shortened. Optionally, in this embodiment, the chain process 101 corresponds to a chain database 108, the chain database 108 stores block data and transaction data, the executor process 102 corresponds to a state database 109, and the state database 109 stores state root information and account information.
The chain process 101 calls the chain database 108 or outputs data to the chain database 108, and the executor process 102 calls the state database 109 or outputs data to the state database 109.
Optionally, the chain process 101 and the executor process 102 may be capable of communicating with each other, or the chain process 101 and the executor process 102 may also be capable of communicating with other processes, and when communicating with other processes, the information subscribed by the chain process 101 and the executor process 102 includes consensus computing information, network synchronization block information, and proposal pre-execution information.
It should be noted that, in this embodiment, in other embodiments, the consensus computing information may be computed by a consensus module specifically set on the right. That is, the chain process 101 may only include the basic operations in the transaction distribution process 104 and the block uplink process 103, and the workload certification with large computation amount is sent to the consensus module for computation, so as to further improve the computation efficiency.
Optionally, both the chain process 101 and the executor process 102 can be queried by a Remote Call process 107 (RPC), so that the chain process 101 and the executor process 102 can be called by a Remote user.
