The title of the invention is "Blockchain-based high-concurrency fast transaction and verification method", And the priority of a Chinese patent application filed with the Chinese Patent Office on August 8, 2019, with application number 201910730535. 7. The title of the invention is "Blockchain-based partition transaction method and system", the entire content of which is incorporated by reference in In this application.

Technical field

This application relates to the field of blockchain transaction technology, and in particular to a partition transaction method and system based on blockchain. Background technique

The main task of blockchain technology is to create a relatively objective non-repudiation digital environment in accordance with the requirements of the decentralized system and based on public consensus. Based on blockchain technology, the authenticity of network information can be guaranteed. For example, if a transaction occurs in the blockchain network, the nodes in the network will generate block data recording the transaction content based on the transaction information, and complete the block data. In network broadcasting, other nodes in the network store block data at the same time, forming unalterable block chain data.

The trading platform built for the implementation of blockchain technology can be local or global. If it is a global trading platform, the synchronization verification of related transactions will be delayed due to network transmission, bandwidth limitations, and node hardware computing capabilities. That is, after a transaction occurs, it needs to be synchronized, verified and accounted by all nodes in the transaction platform to form unalterable blockchain data in the entire network. The valid blockchain data can only be stored after all nodes or a specified number of nodes have completed synchronization and verification. Moreover, the transaction is officially completed only after the corresponding blockchain data is stored. Therefore, the efficiency of the transaction process based on the blockchain technology is very low.

In order to improve the efficiency of verifying transactions, some nodes in the trading platform can be designated as verification nodes for synchronous verification of transactions. For example, the trading platform can designate 21 nodes as verification nodes for transactions on the entire network. When a transaction occurs in the network, the transaction to be verified will be broadcast to these 21 nodes, and the transactions to be verified will be simultaneously verified through these 21 nodes. To improve the efficiency of transaction verification.

However, if the trading platform concurrently sends a large number of transactions in a short period of time, the verification node needs to synchronously verify the transactions one by one in the order of initiation of the transaction. If the synchronization verification time of a transaction is long, the transaction with a later initiation time needs to wait for all transactions initiated earlier to be processed before entering the synchronization verification process, and the waiting time is longer. That is to say, the efficiency of the above verification method in processing large-scale and high concurrent transactions is still low.

detailed description

The embodiments will be described in detail below, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementation manners described in the following examples do not represent all implementation manners consistent with this application. It is only an example of a system and method consistent with some aspects of the present application as detailed in the claims.

In the technical solution provided by this application, the blockchain network refers to a point-to-point (P2P) network with a decentralized application architecture, and the blockchain network can perform distributed storage, public consensus, digital encryption, transaction accounting, and verification. That is, a trading platform that covers distributed technology, cryptography, P2P network architecture, and various consensus algorithms that may be applied. Blockchain or blockchain data refers to the accounting information generated according to transaction information when transactions occur in the blockchain network, that is, multiple specific transactions form a block, and multiple blocks form an ordered block chain.

The blockchain network includes nodes that establish a peer-to-peer network connection with each other. Each node is equipped with a corresponding consensus mechanism, such as a smart contract, and has sufficient computing power to perform transaction verification and accounting procedures. The node also has an interface specification that meets a certain unified standard to realize access to more nodes or other types of blockchain networks through the interface specification.

In this application, the transaction is in a broad sense and does not refer to "commodity trading" or "item exchange" in the traditional sense, but refers to a certain data operation content or operation result on the blockchain network, for example, on the network A certain blockchain node A initiates a query request a for the performance of a certain type of communication device, and the query request a is a transaction for the blockchain node B that undertakes the query service. The same is true. It is also a transaction that node B sends the performance table b of this type of communication device obtained by the query to node A. Information A, a and information B, b will be written into the data block of the blockchain as transaction information.

Refer to Figure 1, which is a schematic flow diagram of a partitioned transaction method based on blockchain in this application. As shown in Figure 1, the first aspect of this application provides a block chain-based partition transaction method, which includes the following steps:

S11: The transaction initiating node broadcasts the transaction to be verified, and the transaction to be verified includes the specified verification method information. In practical applications, the transaction initiation node can be any node on the current trading platform. When a transaction occurs, the node that is the transaction initiator, that is, the transaction initiation node, can trigger the generation of a transaction according to the transaction demand, and this transaction includes the transaction initiation The information of the node, the information of the target node of the transaction and the specific content of the transaction, etc. After the transaction is generated, the transaction initiating node can broadcast the transaction in the network so that the verification node in the network can verify the transaction and generate blockchain data. In this application, the transaction broadcasted from the transaction initiating node has not been verified by the verification node, so it becomes the node to be verified.

In order to quickly complete the verification of the transaction, in the technical solution provided in this application, the transaction to be verified may include the verification method information specified by the transaction. Since in traditional transaction applications, the verification of blockchain transactions requires full network verification, therefore, in the solution provided in this application, the transaction to be verified needs to include this full network verification method; and as a way of rapid verification In this application, the transaction to be verified may also include sub-network verification, that is, verification can be completed through some nodes in the transaction platform. Therefore, in order to complete the corresponding sub-network verification, the application network needs to be divided into multiple sub-networks (or partitioned networks) in this application.

In this application, multiple forms of sub-network division can be referred to. For example, the sub-network can be divided by region. This division method is mainly for global trading platforms. If the transaction initiating node and the transaction target node are relatively close, or belong to the same region or adjacent regions, when trading , Can be in the broadcast pending transaction Specify the authentication method as the subnet corresponding to the region.

The network can also be divided according to the importance of transactions and the hardware conditions of the nodes. Since the more important transactions, the more complex the encryption algorithm and the greater the amount of calculation in the corresponding decryption process. Therefore, in practical applications, nodes with better hardware configuration can be specially partitioned on the same sub-network to quickly complete decryption and verification through hardware configuration.

It can also be divided according to the type of transaction, which can include industry, transaction method, etc. For example, the sub-networks are divided according to industries, that is, the transaction verification process in the same industry is verified by verification nodes in the same sub-network; another example, if the transaction method is a certificate exchange exchange, it can be verified in the same sub-network; the transaction method is Information exchange can be verified in the same subnet.

In some embodiments of the present application, as shown in FIG. 2, the verification method information is the transaction verification range specified by the transaction initiation node, including full network verification and partition network verification; the transaction initiation node broadcasts the step of the transaction to be verified , It also includes the following steps:

Sill: The transaction initiation node obtains the transaction type of the transaction to be verified, and the transaction type includes large transactions and small transactions;

S112: The transaction initiating node generates designated verification method information according to the transaction type;

S113: If the transaction type is a block transaction, generate designated verification method information including full network verification;

S114: If the transaction type is a small-amount transaction, generate designated verification mode information including partition network verification. In this embodiment, the transaction types include large transactions involving a global scale, such as transactions between countries, regions and regions, organizations and organizations. However, the requirements for transaction efficiency are not high, and the transaction security The requirements for security and reliability are high. Such transactions can be designated for full network verification to improve the security and reliability of verification. Transaction types also include small transactions involving individuals. For small transactions, the transaction pays more attention to the efficiency of the transaction, and the number of nodes participating in the verification meets a certain number, so the verification method can be specified as a partition network Ways of identifying.

It should be noted that in the technical solution provided by this application, the transaction types include but are not limited to the above-mentioned block transactions and small transactions. In actual application, the actual application situation can be further divided into transaction types, for example, according to the transaction amount: large-value transactions and small-value transactions; according to the real-time nature of transactions: instant transactions, deferred transactions, or other agreed transactions According to the transaction content: transfer transactions (exchange transactions), payment transactions, smart contract transactions, option transactions, futures delivery transactions, etc. and according to transaction participants: institutional transactions, organization transactions and individual transactions.

In practical applications, the verification range of the transaction can be specified according to different transaction types, that is, to determine whether the transaction is verified on the whole network or on a partitioned network. As long as the transaction process is a transaction that uses different scopes for verification according to different transaction types, it belongs to the protection scope of this application.

Further, in order to subsequently locate the sub-network for synchronization verification, in some embodiments of the present application, as shown in FIG. 3, if the transaction type is a small transaction, the method further includes:

S115: The transaction initiating node broadcasts the query transaction according to the transaction to be verified;

S116: The partition network node that receives the query transaction determines whether the partition network to which it belongs supports the transaction to be verified;

S117: If the partition network supports the transaction to be verified, feed back the partition network identification information to the transaction initiating node;

S118: The transaction initiating node adds the identification information to the specified verification method information.

It can be seen from the above steps that the transaction initiating node can broadcast the transaction to be verified according to the transaction type, if The transaction type is a small transaction, that is, a transaction that is verified through a sub-network in the subsequent verification, and a sub-network address that can satisfy the transaction can be determined by broadcasting a query transaction. After the query transaction is broadcast, any partition network node that receives the query transaction can respond according to the query transaction to determine whether the partition network where it is located can verify the transaction.

If the network node determines that the partition network where it is located can satisfy the transaction, it will feed back the identification information corresponding to the partition network to the transaction initiating node. The identification information may be address information corresponding to the network, or a location identification converted into a specific way according to the address information.

In this embodiment, due to the large number of nodes in the verification network, after the query transaction is broadcast, multiple nodes may have received the transaction. In order to prevent repeated information processing and improve efficiency, in this application, one node After receiving the query transaction, a stop feedback instruction can be broadcast to other nodes in the same partition network, so that other nodes in the partition network can stop responding to the query transaction after receiving the stop feedback instruction. In order to further improve the processing efficiency, the node that first receives the query transaction can broadcast the stop feedback instruction.

In addition, it is also possible to define a query node specifically for feeding back the identification information of the partition network in the verification network, that is, after the current network receives the query transaction, the ordinary verification node does not respond to the query transaction, but only the query node The identification information of the current zoned network can be fed back for the query transaction. This is to avoid information redundancy caused by all nodes responding. In order to improve the efficiency of information feedback, nodes near the location of the verification network interface can be configured as query nodes, so that the query nodes can receive the query transaction earlier. It should be noted that, in order to prevent the query node from being illegally infringed and network congestion caused by excessive data processing, in practical applications, which node serves as the query node may be random or may change periodically among multiple nodes. In this way, it is possible to prevent hackers from directional attack and query nodes, causing nodes to be illegally infringed, and to balance the computing power of nodes.

S12: The maintenance node locates the verification network according to the designated verification method information, and broadcasts the transaction to be verified to the verification network; the verification network is the entire network or a sub-network corresponding to the designated verification method information.

In the technical solution provided in this application, the maintenance node is only a general term for the nodes that process the transaction to be verified, that is, the node that locates the verification network according to the specified verification method information is called the maintenance node, and the maintenance node can be in the network platform The pre-designated node may also be the node that first receives the transaction to be processed, or the transaction initiating node itself. Which node is actually suitable for use as a maintenance node can be determined by itself according to the actual network division.

In practical applications, there may be multiple nodes as maintenance nodes, and the node for locating the verification network according to the specified verification mode information may be one of multiple nodes, or it may be completed by a common network application on multiple nodes. After locating the verification network, the transaction to be verified can be directed and broadcast to the positioning verification network. Since in this application, the specified verification method information includes full network verification and sub-network verification, in this step, the broadcast verification network includes the full network and the sub-network specified in the designated verification method information. That is: if the specified verification method is network-wide verification, broadcast to the entire network; if the specified verification method is sub-network verification, the transaction to be verified is broadcast to the specified sub-network.

S13: The verification node in the verification network performs verification and accounting on the transaction to be verified, and generates blockchain data according to the verified transaction.

In this application, after the transaction to be verified is forwarded and broadcasted by the maintenance node, the node in the verification network can perform synchronous verification of the transaction to be verified, and form block data after the verification is passed, and perform accounting to complete distributed storage. The specific synchronization verification method can be the same as the existing verification method, but the distributed storage method is different from the existing storage method. That is, in some embodiments of this application, if the verification network is a sub-network, the method further includes : S14: Synchronize the blockchain data to all network nodes.

In the solution of this application, since the node resources and time consumed for verification are relatively long, and the number of verification passes meets certain requirements, it means that the data corresponding to the transaction is meaningful. Therefore, the verification process in this application can pass through the sub-network Instead, the distributed storage process has no direct impact on the transaction, and it takes a long time and has no other obvious disadvantages. However, in order to make the accounting data obtain the consensus of the entire network and improve its anti-repudiation effect, in practical applications, after the blockchain data is generated in the sub-network, it is also necessary to synchronize the generated blockchain data to the nodes of the entire network. For distributed storage throughout the network.

This embodiment can reduce the verification time by synchronizing the blockchain data, and at the same time, the generated blockchain data is stored in the entire network node. Therefore, its anti-repudiation effect is the same as that of traditional blockchain transactions. the same. That is, this embodiment can improve transaction efficiency under the premise of meeting the anti-repudiation effect.

Correspondingly, as shown in FIG. 4, if the verification network is a full network, the method further includes:

S15: The verification nodes in the entire network store the generated blockchain data, and broadcast the blockchain data within the entire network;

S16: The participating nodes in the entire network store the blockchain data.

In this embodiment, the nodes in the entire network can be pre-divided into multiple roles, including verification nodes, maintenance nodes, and participating nodes. After the transaction that is verified by the whole network generates blockchain data, the verification node must first store the generated blockchain data. At the same time, the verification node can also broadcast the blockchain data across the entire network, so that all participating nodes in the entire network can receive the blockchain data and store the blockchain data, thereby improving The coverage of distributed storage ensures that blockchain data has a good anti-repudiation effect.

Based on the above partitioned transaction method, as shown in FIG. 5, this application also provides a partitioned transaction system based on a blockchain, including a blockchain network established by multiple nodes, wherein part of the blockchain network The node is configured as a verification node, and multiple verification nodes form a verification network; the verification network is divided to form multiple sub-networks; some nodes in the blockchain network are configured as maintenance nodes; any one of the blockchain networks Nodes can be used as transaction initiation nodes;

In the second aspect of the present application, another block chain-based partition transaction method is also provided, as shown in FIG. 6, including The following steps:

S21: The transaction initiating node broadcasts the transaction to be verified.

In this embodiment, the verification method may not be specified in the transaction to be verified broadcasted by the transaction initiating node, but the transaction type of the broadcast to be verified transaction is judged by the maintenance node to determine the verification method according to the transaction type.

S22: The maintenance node in the public chain network judges the transaction type according to the transaction to be verified; the transaction type includes large transactions and small transactions.

In practical applications, the transaction to be verified must include transaction initiation node information, transaction target node information, and transaction summary, and the maintenance node can extract this information to determine the transaction type of the transaction to be verified. Among them, transaction types include block transactions and small transactions. In the same way, large transactions can be transactions between countries, regions and regions, organizations and organizations (alliances and alliances) that occur on a global scale, while small transactions can be transactions between individuals and individuals in a small area. Transactions between individuals and small organizations, small organizations and small organizations (company to company). Whether the actual transaction to be verified is a large transaction or a small transaction can be specified in the transaction to be verified, and it can be indirectly determined through the transaction summary and the initiating node information and the transaction target node information.

In the technical solution provided by this application, a public chain network can be pre-defined in the transaction platform, the public chain network can provide basic functions for transactions, and the transaction platform with each function can be used as an access link into the public chain network. The maintainer node can be used as part of the public chain, and the verification network can also be composed of part of the public chain network, can also be composed of some nodes in the access chain, and can also be composed of the public chain and the nodes of the access chain. .

It should be noted that this application uses the maintenance node in the public chain as an example to determine the transaction type. In actual applications, the public chain network may not be defined in advance, and the nodes in the trading platform are directly used as the maintenance nodes, which is essentially The data processing process is basically the same, and all belong to the protection scope of this application.

Further, the current network partition strategy table is stored in the maintenance node. As shown in FIG. 7, the maintenance node in the public chain network judges the transaction type according to the transaction to be verified, including:

S221: The maintenance node invokes the partition strategy table;

S222: Match the partition network that can satisfy the transaction to be verified in the partition strategy table, and extract all verification node addresses in the matched partition network;

S223: Broadcast the transaction to be verified to all verification nodes according to the verification node address.

It can be seen from the above steps that in order to facilitate rapid positioning of the sub-network, a partition strategy table can be built in the maintenance node. The partition strategy table records the partition strategy of all verification networks in the current trading platform. Each partition network can be indicated by identification information. Corresponding to the supported verification functions. By calling the partition strategy table, it is possible to match the partition network that can satisfy the transaction to be verified in the partition strategy table, and obtain the addresses of all verification nodes in the partition network, so as to broadcast the verification transaction to the verification nodes according to the obtained node addresses. In order to improve the efficiency of broadcasting, one-to-many synchronous broadcasting can be adopted in practical applications.

S23: If the transaction type is a small transaction, broadcast the transaction to be verified to the partition network corresponding to the transaction to be verified.

In this embodiment, if the transaction type is a small-value transaction, it can meet the conditions for rapid verification through the sub-network, and therefore, the transaction to be verified can be broadcast to the sub-network. The verification node in the sub-network can verify the transaction to be verified to generate blockchain data, namely:

S24: The verification node in the partitioned network performs verification and accounting on the transaction to be verified, so as to generate blockchain data according to the transaction to be verified. In this embodiment, after determining that the transaction type is a small transaction, the maintenance node can determine the verification network situation corresponding to the exchange by extracting the information recorded in the transaction summary, so as to locate the sub-network that matches the transaction to be verified. For example, if the transaction to be verified is a certificate exchange exchange, after extracting the transaction summary information, it can be determined that the transaction needs to be verified by the sub-network responsible for the exchange function of the certificate exchange. Therefore, the transaction to be verified can be broadcast to the sub-network of the exchange function. In addition, in actual applications, the molecular network can be further refined according to the actual application environment. For example, for the same exchange transaction, the sub-network that is more in line with the corresponding requirements can be further determined for verification according to the exchange type extracted from the transaction summary.

S25: The partitioned network synchronizes the blockchain data to all network nodes.

After the block chain data is generated in the partition network, in order to increase the scope of distributed storage, the block chain data can be synchronized across the entire network to improve the anti-repudiation effect of the block chain data.

In some embodiments of the present application, as shown in FIG. 6, if the transaction type is a block transaction, the method further includes the following steps:

S26: The maintenance node in the public chain network broadcasts the transaction to be verified to the entire network;

S27: The verification node in the entire network performs verification and accounting on the transaction to be verified, so as to generate blockchain data according to the transaction to be verified.

Based on the above-mentioned partitioned transaction method, this application provides a partitioned transaction system based on blockchain, as shown in FIG. 8, including a public chain composed of multiple nodes, and an access chain connecting the public chain; Some nodes in the chain are configured as maintenance nodes, and some nodes in the public chain are configured as verification nodes; multiple verification nodes form a verification network, and the verification network is divided to form multiple partition networks; the public chain and access Any node in the chain can be used as a transaction initiation node; the transaction initiation node is configured to: broadcast the transaction to be verified;

It can be seen from the above technical solutions that this application provides a block chain-based partition transaction method and system. The method first broadcasts the transaction to be verified by the transaction initiating node; and then the maintenance node in the public chain network according to the transaction to be verified , Determine the transaction type; the transaction types include large transactions and small transactions; if the transaction type is a small transaction, broadcast the transaction to be verified to the partition network corresponding to the transaction to be verified; The verification node performs verification and accounting on the transaction to be verified to generate blockchain data according to the transaction to be verified; finally, the partition network synchronizes the blockchain data to the entire network node. According to different transaction types, the method can perform two modes of full network verification and partition network verification respectively, so that when a specific type of transaction is processed, the partition network can be quickly verified, and the entire network will synchronize the blockchain after the verification is completed.
