Description

Transaction batch processing system and method using block chain

The present invention relates to a transaction batch processing system using a blockchain and a method thereof, and more particularly, to a first node by transmitting a first block inserted with a large amount of transactions to a first node generating a block at the present time. The present invention relates to a transaction batch processing system using a block chain and a method for enabling batch processing by distributing the generated second block and the first block together.

Blockchain is a decentralized data storage technology that stores data in blocks and connects them in a chain form. Also called a public trading ledger, it sends the transaction history to all users participating in a transaction without keeping transaction records on a centralized server, and every transaction participant can share and contrast information to forge or alter data. Do not.

The information stored on the blockchain varies, so not only electronic payments and digital certifications, but also tracking the entire process from cargo tracking systems, P2P loans, origins to distribution, or genuine appraisal of art, counterfeit money, electronic voting, electronic citizenship, vehicle sharing It can be used in various fields that require reliability, such as real estate registers and medical record management shared between hospitals.

Meanwhile, the blockchain is divided into a public blockchain and a private blockchain, and the public blockchain is open to everyone, such as Bitcoin or Ethereum, and everyone can participate, and the private blockchain is operated and used by an institution or a company. As the number of participants is limited, it has the advantage of being fast in the state.

In the general blockchain processing method, when a transaction is created in one node, the transaction is transmitted to a node that can generate a block at the present time, and the node receiving the transaction receives agreement from other nodes to verify the transaction. Proceed. The validated transaction is stored in the generated block and the stored block can be distributed to all the participants' computers by including the hash value and distributing it to other nodes.

However, the conventional method has a problem that the processing speed is slow because 10,000 processes of transaction generation-> delivery-> verification-> block storage-> block distribution are performed when 10,000 transactions are performed.

The background technology of the present invention is disclosed in Korean Unexamined Patent Publication No. 2018-0014534 (published Feb. 09, 2018).

The technical problem to be achieved by the present invention is to transmit a first block in which a large amount of transactions are inserted to a first node that generates a block at the present time, thereby combining the second block generated at the first node with the received first block. It is to provide a transaction batch processing system using a block chain and a method for enabling batch processing by distributing by chaining.

According to an embodiment of the present invention for achieving the above technical problem, in a transaction batch processing system using a block chain, it consists of a plurality of nodes for generating a block at a specific time point, and receives the block broadcast from the node to verify And a node that is not authorized to create a block when a transaction is generated, and includes a user terminal that generates a block by collecting a transaction generated for a predetermined time.

The user terminal is delegated block generation and transaction processing from the blockchain network, inserts a large amount of transactions into one block, generates a first block, and is created as a first node having a right to generate a block at the present time. Deliver the first block.

The user terminal stores the generated transaction for a certain period of time or until a certain capacity, and then collects a large number of transactions at once or collects a large number of instantaneous transactions, and inserts the collected transactions into one block to insert the first transaction. You can create a block.

The user terminal, The first block is generated by inserting the generated large number of transactions into the block, but the transaction may insert the transaction into the first block while the verification is completed by itself.

The first node chains the second block generated by the first node and the first block received from the user terminal, and the first block and the second block contain different hash values. Broadcast to nodes.

A second node having a right to create a block at a next time point may generate a third block and chain the third block to the first block.

According to another embodiment of the present invention, in a block chain transaction batch processing method using a transaction batch processing system, generating a first block by aggregating a plurality of transactions generated for a predetermined time in a user terminal, the user terminal Delivering the first block generated by the second node to a first node having a right to create a block at the current time point, and a first node having a right to generate a block at the current time point; And broadcasting the second generated block to the blockchain network.

As described above, according to the present invention, a first block is formed by verifying a plurality of transactions collected after storage by a user terminal for a predetermined period or a predetermined capacity by forming a first block, and then generating a block at the present time. Batch processing or batch processing may be possible since the second block generated in the first node and the first block received from the user terminal are chained together and distributed together.

In addition, according to the present invention, it is possible to share information to everyone about a large number of transactions, such as a public blockchain, but a batch processing is possible because a large number of transactions are inserted and distributed in a single block in a collected state. The speed of verifying and distributing the data can be as fast as a private blockchain.

In addition, according to the present invention, since the blockchain used by the enterprise has information and legal responsibility, the user terminal of the enterprise delegates the block creation and transaction processing to insert a large amount of transactions into one block. Since blocks are created, and the generated blocks are distributed in the blockchain network, no agreed verification from multiple nodes is required, so a large amount of transactions can be processed at once and the processing speed is high, thereby reducing the burden on the network.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In this process, the thickness of the lines or the size of the components shown in the drawings may be exaggerated for clarity and convenience of description.

In addition, terms to be described later are terms defined in consideration of functions in the present invention, which may vary according to a user's or operator's intention or custom. Therefore, the definitions of these terms should be made based on the contents throughout the specification.

First, a general block generation and processing method will be described with reference to FIG. 1.

1 is a view for explaining a general block generation and processing method.

Referring to the block generation and processing method shown in FIG. 1, a block is a unit for storing data, and is divided into a body and a header, and a block is generated every 10 minutes. However, the block may generate a block only at a node capable of generating the block at a current time point among a plurality of nodes. Accordingly, the generated transaction is transmitted to a node capable of generating a block at the present point of time (S110), and the node receiving the transaction determines whether to insert the transaction into the block by obtaining agreement of other nodes in order to generate the block. (S120).

After the agreement is completed, the transaction is inserted into a block and broadcasted to another node to be stored in each node (S130), and the block to be stored is chained to the previously stored block (S140).

In other words, a generated transaction is delivered to a node capable of generating a block at the point of time when the transaction occurs, so that the generated block can be generated, and the generated block is broadcast to multiple nodes. It can be stored in the form of a blockchain.

For example, a shopping mall or a card company delivers one transaction out of 10,000 transaction information to a node that can generate a block at the present time after closing the daily order. After receiving the transaction, the node receives the agreement of other nodes and inserts the transaction into the block. When the node reaches a certain size, the node closes the block and broadcasts it to another node.

In this way, since 10,000 times are repeated until 10,000 transactions are completed, processing is difficult at the node, so that the server is down, or tens of thousands of nodes are connected and processed, thereby significantly reducing the processing speed.

2 is a block diagram of a transaction batch processing system using a blockchain according to an embodiment of the present invention.

As shown in FIG. 2, a transaction batch processing system according to an embodiment of the present invention includes a user terminal 100, a node 200, and a blockchain network 300.

The user terminal 100 is a terminal capable of generating a transaction according to an online transaction, and refers to a terminal used by an individual or a company.

Since the user terminal 100 cannot generate a block at the time when a transaction is generated for each generated transaction, the user terminal 100 stores the generated transactions according to an online transaction until a certain period or a fixed capacity is reached so that they can be collected at once. Store a large number of transactions that occurred at one time.

The node 200 is an individual server, that is, a participant, and the node 200 plays a role of block generation, distribution, and storage, and includes a hash function when generating a block.

The blockchain network 300 allows the transaction history information to be distributed and stored in the computer of the online network participants without being concentrated on a specific server when an online transaction occurs. When a transaction occurs, verification is performed by each participant, that is, a node. If agreement is obtained from the participating nodes, a block is created and distributed to each node. Therefore, hacking is impossible in principle because the book itself is open on the Internet and verified from time to time.

3 is a flowchart illustrating a method of processing a large amount of data using a transaction batch processing system using a blockchain according to an embodiment of the present invention, and FIG. 4 is a diagram illustrating an example of block generation performed at a node illustrated in FIG. FIG. 5 is a diagram illustrating a form in which a block generated in the massive data processing method of FIG. 3 is broadcast and chained with a third block.

In more detail, FIG. 3 is a flowchart illustrating a method for batch processing at a time when a large amount of transactions are generated in the user terminal 100.

First, the user terminal 100 collects the generated transactions (S310).

Here, the transaction is not a single transaction history, but a large amount of transaction history, which is stored in the user terminal 100 until a reference amount for a predetermined time and collected at once, or may be collected when there are a large number of instant transactions. .

In this case, a large number of transactions means more than 1000 transactions, and the design can be changed according to the application area or scale of the process.

Next, the collected transaction is verified by the user terminal 100 by itself (S320), and when the verification is completed, a first block is generated by inserting a large number of transactions into one block (S330).

Although the user terminal 100 is a node that cannot generate a block at the present time, the user terminal 100 generates a block by being delegated a role capable of generating a block and processing a transaction.

In addition, the user terminal 100 does not obtain a consensus through algorithms from other nodes for the collected large number of transactions, and performs verification for the transaction itself so that a large number of transactions can be inserted into one block.

Meanwhile, the generated first block broadcasts to the first node 210 generating the block at the present time (S340).

At the present time, the first node 210 generating the block receives a transaction transmitted from another node 200 other than a large amount of transactions generated by the user terminal 100, and transmits the received transaction to another node 200. The second block can be generated by receiving the verification from the block and inserting the block into the block. Therefore, the first node 210 receives the first block from the user terminal 100 in a state where the new second block is generated, so that the first node 210 can be connected in the form of a chain (S350).

The two blocks connected in the form of a chain may broadcast a plurality of nodes 200 so that a large amount of transactions may be processed in a batch (S360).

The plurality of nodes 200 receiving the two blocks are chained to the previously stored blocks and stored (S370).

For example, shopping malls, card companies, financial companies, etc., where e-commerce transactions occur, a transaction occurs every time a transaction occurs. If the deadline for a transaction is about 4 to 4:30 am, One or more large transactions occur.

However, the user terminal 100 aggregates the entire transaction without transmitting only one transaction to the first node 210 capable of generating a block at the present time, from among a large number of transactions generated until 4 am to 4:30 am. Collected bulk transactions are stored on the server and can be verified on their own.

At this time, since self verification occurs in the user terminal 100, there is no need to derive algorithm agreement from the other node 200. However, responsibility for an error that may occur in the verified transaction may be handled in the user terminal 100.

A large number of verified transactions are inserted into one block to generate a first block, and the generated first block broadcasts to the first node 210 that can generate a block at the current time. However, the first node 210 capable of generating a block at the present time is a state in which a block called a second block is generated through algorithm agreement from other nodes with respect to a transaction generated at the present time, and the user terminal 100 is generated. Chain the first block received from the second block to the second block, and broadcast to another node with a hash value included in each block.

On the other hand, as shown in Figure 4, since the other nodes 200 are stored in the Genesis block, the first block and the second block received while being chained are the "Genesis block"-"second block"-"first block" Blockchains are formed in order so that they can be stored.

In addition, if the second node 220 having the authority to generate the block at the next time point receives the transaction and generates the transaction in the third block, as shown in FIG. 5, the second node 220 receives the first node from the first node. The third block may be chained to the second block and the first block.

Therefore, the present invention can process a large number of transactions as a single transaction, so that it can be broadcast to tens of thousands of connected nodes, but as fast as in a specific network can be achieved.

Although the present invention has been described with reference to the embodiments shown in the drawings, this is merely exemplary, and it will be understood by those skilled in the art that various modifications and equivalent other embodiments are possible. will be. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the following claims.

100: user terminal
200: node
210: first node capable of generating a block at the present time
220: a second node capable of generating a block at the next time point
300: blockchain network
