Description

Device for anchoring blockchain

The present invention relates to an apparatus for anchoring a blockchain, and more particularly, to an apparatus for performing anchoring to solve limited verification capability by a small number of nodes, which is a chronic problem of the blockchain.

The biggest reason blockchain technology is in the spotlight is decentralization. This decentralization means that the integrity of data as well as identity can be trusted without the mediation or trust of the mediator, which can create more possibilities and opportunities in the anonymous network called the Internet.

However, blockchains that have been tested since the commercialization of Bitcoin are being challenged with scalability.

In other words, as the number of participants participating in the blockchain increases, the blockchain's processing speed slows down due to the limited network speed and storage capacity due to the nature of the blockchain that needs to keep the same data. It is a problem.

In addition, while Bitcoin and the 2nd generation Ethereum platform, which appeared at the beginning of blockchain, maintained decentralization and security, Bitcoin only supports 3 ~ 4 transactions per second and Ethereum supports only 7 ~ 8 transactions per second. It has a big limitation in terms of processing speed.

As a result, it is difficult to use it as a payment method as a cryptocurrency due to such a speed problem, and it shows a limit as the network gradually expands.

The reason for this slow transaction rate is because the size (size) of blocks created at regular intervals over time and the transactions that can be contained in the blocks are limited.

The technology related to the block chain, Korean Patent No. 1628005 "Copyright forgery detection system of digital contents based on block chain, 2016.06.13." Has been disclosed.

In the prior art, the copyright interest of the copyright holder stored and managed in the server operated by the content provider is converted into an amount, and the copyright holder detects the copyright interest by detecting and blocking the information necessary to exercise the copyright interest of the copyright holder. It provides a blockchain-based detection system that guides you to exercise properly.

However, the prior art does not consider the limited verification ability by a small number of nodes, which is a chronic problem of the block chain, and thus has a limitation in the verification ability, and a problem that cannot always be defined between block chains separated from each other. have.

The blockchain consists of a private blockchain with a relatively small number of nodes and a public blockchain with a relatively large number of nodes.

The present invention is to address the limited problem of limited verification by a small number of nodes, which is a chronic problem of the private blockchain, and is more public than the private blockchain. We will configure the device that performs the anchoring process that is additionally verified by periodically storing the information of the private blockchain.

An apparatus for anchoring a blockchain, the apparatus comprising: a blockchain holding first blockchain network including information to be exposed generated using user information, and an upper block receiving and storing information to be exposed from the first blockchain network The chain holding second blockchain network, the first blockchain network, and the second blockchain network are characterized by converting stored data into data of fixed length.

The first blockchain network combines at least one or more information to be exposed and transmits the information to the second blockchain network, wherein the first blockchain network is selected based on a user-set criteria or randomly selected. The information to be combined is transmitted to the second blockchain network.

The device is an outbound relay for transmitting information from the first blockchain network to the second blockchain network to deliver information to be exposed of the first blockchain network to the second blockchain network. An inbound relay for transmitting information from the second blockchain network to the first blockchain network and operating in the second blockchain network, the inbound information received from the outbound relay; It characterized in that it further comprises a reflector for replicating to a relay (Inbound Relay). In addition, the information to be exposed is characterized in that the hash information.

Through the anchoring process, the problem of limited verification ability that occurs when a small number of nodes, which is a chronic problem of the blockchain, can be solved.

In other words, by storing the information of the blockchain that is less capable of verification in the upper blockchain, which has excellent verification ability, and verifying it further, it can demonstrate verification ability in various fields such as contract, transfer, and information exchange.

In addition, when the upper blockchain is verified, accuracy may be further improved by combining and transmitting information, transmitting according to a user's setting criteria, or combining and exposing information to be randomly selected.

1 illustrates a blockchain according to an embodiment of the present invention.

2 is a view showing an anchoring using a reflector according to an embodiment of the present invention.

Hereinafter, the technical spirit of the present invention will be described in more detail with reference to the accompanying drawings.

The accompanying drawings are merely examples for explaining the technical idea of the present invention in more detail, and thus the technical idea of the present invention is not limited to the accompanying drawings.

1 is a view showing a blockchain according to an embodiment of the present invention. Referring to FIG. 1, the blockchain is a small chain of data called 'blocks' to be managed in a chain-based distributed data storage environment in which chain-based data is generated based on a P2P scheme. It is a data forgery prevention technology based on distributed computing technology that can read the results. In other words, the newly generated information is also blocked and stored in another block system instead of being stored only where it is generated.

The biggest reason blockchain technology is in the spotlight is decentralization. This decentralization means that the integrity of data as well as identity can be trusted without the mediation or trust of the mediator, which can create more possibilities and opportunities in the anonymous network called the Internet. However, as the number of participants participating in the blockchain increases, the processing speed of the blockchain is slowed down due to the limited network speed and storage capacity due to the nature of the blockchain that must store the same data.

Blockchains can be broadly divided into private blockchains and public blockchains. An important criterion for distinguishing between private blockchains and public blockchains is the number of nodes that make up each blockchain. Here, a node refers to a computing entity (for example, a server) capable of storing blocked data and consequently verifying the data integrity of the blockchain.

Thus, for example, a bitcoin network with many nodes connected can be considered a public blockchain, and a blockchain that is used internally within an enterprise infrastructure and has a limited number of nodes can be thought of as a private blockchain.

Due to the chronic problem of the private blockchain defined by this classification, limited verification capability by a small number of nodes is increasingly presented as a problem. Anchoring is defined and proposed in the present invention to solve this problem of verification capability.

For example, to define anchoring, the private blockchain can store the information of the private blockchain periodically in a public blockchain that has better verification ability and has more nodes. The integrity of the chain can be further verified. This behavior can be defined as anchoring. Herein, the act may mean that the computing subject exchanges meaningful information with another computing subject through a specific computing means.

In a similar sense, the verification ability of a system that forms a blockchain is defined as the hierarchical order of the blockchain, and a blockchain with a higher hierarchical order (for example, a public blockchain) is defined as a blockchain with a lower hierarchical order (for example, a private block). It can be defined that it is at a higher level (chain). In this sense, the definition of anchoring may be to store information of an arbitrary blockchain in a higher-level blockchain separated from an arbitrary blockchain. As a result, such an anchoring can increase the reliability of arbitrary blockchain information.

Although anchoring has a strong aspect of verifying information, it also provides a function of an interoperable system for exchanging information between separate blockchain systems when a relay or gateway node, which will be described later, is strengthened. can see.

As such, an anchoring method may be defined as an offline anchoring method by fixing data to be anchored based on the state of the blockchain. The main difference between the offline anchoring and other online / dynamic anchoring methods depends on whether or not the information to be anchored can be changed later according to a policy of a user or a system. This will be described later.

Offline anchoring is also called static anchoring.

An anchoring device based on a blockchain according to an embodiment of the present invention is largely composed of a first blockchain network and a second blockchain network. The first blockchain network and the second blockchain network are blockchain holding servers, and the first blockchain network includes information to be generated using information of a user, and the second blockchain network An upper blockchain server that receives and stores information to be exposed from the first blockchain network. The first blockchain network and the second blockchain network may convert the stored data into data having a fixed length.

The blockchain is called a blockchain having a relatively small number of nodes, and is called a private blockchain and a public blockchain having a relatively large number of nodes. The first blockchain network and the second blockchain network according to an embodiment of the present invention may be replaced by a private blockchain and a public blockchain, respectively.

The blockchain retaining first blockchain network converts the summarized content or portion of the current content into fixed length data. In this case, the information to be converted to the fixed length of the data is known to be exposed, and the information to be exposed stores a unit of individual information such as transactions, transactions, events, etc. in the blockchain at regular intervals. That is, the information to be exposed converted in one blockchain system is stored in another blockchain system and a higher blockchain system, thereby increasing reliability.

In this case, the information to be exposed may be information such as hash information according to an anchoring embodiment. The hash information is one of general methods for storing, and is not limited to storing hash information, and various types of information may be applied according to embodiments.

In addition, the period of storing the information to be exposed recorded on the first blockchain network in the upper blockchain holding second blockchain network may be performed according to a certain period. According to another embodiment, the information to be exposed recorded on the first blockchain network may be stored whenever a specific condition set by the user is satisfied.

That is, at least one or more pieces of information to be recorded in the first blockchain network are combined, and are combined at regular intervals in units of individual information and transmitted to the second blockchain network.

If anchoring occurs frequently, there is a problem that the traffic between blockchains occurs frequently and the user experiences a drop in speed. If the anchoring occurs too little, the stability of the private blockchain is lowered, resulting in unreliable results. Therefore, if the storage according to a certain period or a specific condition according to an embodiment of the present invention can not increase the user's haptic speed, it is possible to increase the reliability.

The process for periodically performing the process of additionally storing the information of the private blockchain will be described in detail according to the following embodiments.

First, when transmitting information to be exposed stored in the first blockchain network to the second blockchain network, it is possible to combine and transmit at least one or more information to be exposed, rather than transmitting each piece of information to be exposed.

The information to be exposed, when combining at least one or more information to be exposed, if the target to be verified is explicitly revealed, it is possible to immediately anchor and confirm whether or not a specific message or event occurs and simultaneously anchoring. . In one embodiment, when two accounts send and receive messages, only the portion of the amount is combined and transmitted as information to be exposed, and the remaining general conversation messages may be excluded without combining as information to be exposed. In another embodiment, when a contract is signed on the Internet, only necessary information among contract information may be selected and transmitted as information to be exposed, and other general matters may be excluded without combining.

This approach can be defined as online anchoring.

In addition, when the information to be exposed stored in the first blockchain network is transmitted to the second blockchain network, it is possible to dynamically select and transmit the information to be exposed to anchoring without selecting in advance. That is, it is also possible to dynamically select the anchoring target information without fixing in advance. In the method of dynamically selecting the target information, the target information may be selected or randomly selected according to a predetermined criterion set by the user.

Such an anchoring method may be defined as a dynamic anchoring method.

In one embodiment, the dynamic anchoring selects the time and target of the anchoring. In other words, if a notary is required in the middle of a transaction or conversation, an anchoring can be performed immediately to record only the transaction or conversation in the public blockchain.

In one embodiment, in the case of information exchanged between two people who want to send and receive a message, a message determined to be important among the information exchanged may be verified by passing while anchoring. In other words, if the blockchain is applied to the voting, the user may anchor only the process of checking the result of the voting, or the process of voting itself, or the result of the voting depends on a predetermined condition. It is possible to set whether to anchor the voting process. That is, the dynamic anchoring can secure desired stability by exposing desired information to the public blockchain at any time.

At first glance, online anchoring and dynamic anchoring are both common in that they do not anchor fixed information to be exposed based on state, but online anchoring, for example, changes the data to be anchored (information to be exposed) by changing user settings. On the other hand, dynamic anchoring can be changed dynamically so that the data to be anchored satisfies a specific performance according to the situation of a specific blockchain. As an example of the implementation of dynamic anchoring, if the response speed becomes too slow in consideration of both the system integrity and the response speed of the system, change the data or the period to be anchored in the direction of the system response speed and the large transaction price As the integrity of the system is very important, it is possible to set a strong degree of data, period, etc. to be anchored.

In addition, the information to be exposed stored in the first blockchain network can be anchored through a reflector. 2 is a view showing anchoring using a reflector according to an embodiment of the present invention. 2, the anchoring using the reflector will be described in more detail.

The reflector is a device for copying and re-transmitting the input information to the sender. Referring to FIG. 2, in order to transfer information to be exposed of the first blockchain network to the second blockchain network, the reflector is used in the first blockchain network. An outbound relay for transmitting information to the second blockchain network and an inbound relay for transmitting information from the second blockchain network to the first blockchain network are formed. In addition, it is further provided with a reflector that operates in the second blockchain network and replicates information received from the outbound relay to the inbound relay. That is, referring to FIG. 2, if the user decides to store the message through an anchoring in one account or one contract, and the like dynamically, the user can transmit the data through the upper blockchain through the outbound relay. That is, the reflector operates in a higher blockchain and copies and receives information received from an outbound relay to an inbound relay.

In this case, the relay is composed of an outbound relay and an inbound relay. The outbound relay is a relay for transmitting a message to a higher blockchain system to support the anchoring, and the inbound relay is a relay for transmitting a message from a higher blockchain system to a lower blockchain system. to be. In the above embodiment, the relay is provided to deliver the information to be exposed, and according to the embodiment, it may be implemented in various devices such as a server, S / W program, cloud service.

That is, the information to be exposed is transmitted from the outbound relay to the second blockchain network, and the transmitted information to be exposed is copied to the inbound relay.

Although a relay according to an embodiment of the present invention transmits a message by separating an outbound relay and an inbound relay, according to another embodiment, only one relay is configured to output an outbound relay ( It is also possible to perform both the functions of Outbound Relay and Inbound Relay.

3 is an embodiment of an outbound relay and an inbound relay according to an embodiment of the present invention. A detailed embodiment of the outbound relay and the inbound relay will be described in more detail with reference to FIG. 3.

Accounts containing contract information are formed in the first blockchain network and the second blockchain network including the blockchain system. When anchoring the information of the first blockchain network to the second blockchain network, the connection module of the first blockchain network, the connection module of the second blockchain network and between the first blockchain network and the second blockchain network The transfer module is configured as one to serve as both an inbound relay and an outbound relay.

When anchoring the information of the first blockchain network to the second blockchain network, the information to be anchored is transmitted to the account of the connection module of the first blockchain network. The connection module receiving the information detects the input of the information. When the connection module detects the input of the corresponding information, it may be confirmed by using an event system provided by the blockchain or by monitoring transactions in the blockchain.

In addition, the information transmitted for anchoring, in the blockchain transaction information transformation module, changes the information into a structure usable in the second blockchain network. In other words, it transforms into an information structure corresponding to the second blockchain network.

The transaction containing the information to be anchored is transmitted to the reflector through the second blockchain network. The reflector sends the information back to the account of the second blockchain network. The transmitted information is transferred to the first blockchain network again through a conversion process, and the result of anchoring can be confirmed.

The present invention is not limited to the above-described embodiments, and the scope of application of the present invention is not limited to those of ordinary skill in the art to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. Of course, various modifications are possible.
