Description

Anchoring Method of Block Chain

The present invention relates to a method of anchoring a block chain, and more particularly, to a method of performing anchoring to solve a limited verification capability by a small number of nodes, which is an inherent problem of a block chain.

Decentralization is the biggest reason blockchain technology is in the spotlight. This decentralization makes it possible to trust not only identity but also the integrity of data without intermediaries or guarantees of trust by intermediaries, because more possibilities and opportunities can be created in an anonymous network called the Internet.

However, with the commercialization of Bitcoin, the blockchain, which has been tested, has a scalability problem.

In other words, as the number of participants in the blockchain increases, the blockchain needs to store the same data, so the processing speed of the blockchain slows down due to the limited network speed and storage capacity, and successful commercialization is possible only by solving these speed problems. It is a problem.

In addition, Bitcoin, which appeared in the early stages of the blockchain, and the Ethereum platform, the second-generation platform, maintained decentralization and security, but Bitcoin only supports 3-4 transactions per second and Ethereum 7-8 transactions per second. It has a big limit in terms of processing speed.

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

The reason the transaction speed slows down is that the size (size) of blocks generated at regular intervals over time and the transaction details that can be contained in the block are limited.

The technology related to the blockchain is published in Korea Patent No. 1628005 "A system for detecting forgery and alteration of copyright interest of digital contents based on a blockchain, 2016.06.13." It has been disclosed in

In the prior art, the copyright interest of the copyright holder stored and managed on the server operated by the content provider is converted into an amount, and when information necessary to exercise the copyright interest of the copyright holder is forged, it detects and blocks it, so that the copyright holder It provides a block chain-based detection system that guides you to exercise correctly.

However, the above prior art does not take into account the limited verification ability by a small number of nodes, which is an inherent problem of the block chain, so there is a limitation in verification ability, and a problem that cannot always be defined between separate blockchains. have.

Domestic Registration Patent No. 1628005, "A system for detecting copyright forgery and alteration of digital contents based on blockchain", (2016.06.13.)

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 solve the inherent problem of a private blockchain, a limited verification ability by a small number of nodes, and a public blockchain that has better verification capability than a private blockchain. ), we want to perform the anchoring process for additional verification by periodically storing the information of the private blockchain.

In the blockchain-based anchoring technique, (a) recording the information to be exposed generated using the user's information in the first blockchain network holding the blockchain and (b) recording the information in the first blockchain network It characterized in that it comprises the step of storing the information to be exposed in the second block chain network possessing the upper block chain.

In step (b), at least one information to be exposed in the first blockchain network is combined and transmitted to the second blockchain network, and the exposure selected according to the user's setting criteria in step (b) It is characterized in that the information to be ordered is combined and transmitted to the second blockchain network.

In addition, the information to be exposed randomly selected in step (b) is combined and transmitted to the second blockchain network, and in step (b), the information to be exposed is an outbound relay. It is transmitted to the second blockchain network from the network, and the transmitted information to be exposed is replicated to an inbound relay.

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 an inherent problem of the blockchain, can be solved.

In other words, by storing information of a block chain with relatively low verification ability in a higher level blockchain with excellent verification capability and additionally being verified, it can demonstrate verification ability in various fields such as contracts, transfers, and information exchange.

In addition, when it is verified to the upper blockchain, the information can be combined and transmitted, or it is transmitted according to the user's set criteria, or by combining and transmitting information to be exposed at random, it is possible to increase the accuracy.

Hereinafter, the technical idea of the present invention will be described in more detail using the accompanying drawings.

The accompanying drawings are only an example shown to describe the technical idea of the present invention in more detail, so the technical idea of the present invention is not limited to the form of the accompanying drawings.

1 is a diagram showing a block chain according to an embodiment of the present invention. Referring to Fig. 1, in the blockchain, small data called'blocks' as management target data are stored in a distributed data storage environment based on a chain-type connection created based on the P2P method, so that no one can arbitrarily modify it, and anyone can change it. It is a data forgery prevention technology based on distributed computing technology that allows you to view the results. In other words, newly created information is also blocked, and not only stored there, but also stored in other block systems.

Decentralization is the biggest reason blockchain technology is in the spotlight. This decentralization makes it possible to trust not only identity but also the integrity of data without intermediaries or guarantees of trust by intermediaries, because more possibilities and opportunities can be created in an anonymous network called the Internet. However, as the number of participants in the blockchain increases, the processing speed of the blockchain is slowing 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 largely divided into private blockchains and public blockchains. An important criterion for distinguishing between a private blockchain and a public blockchain is the number of nodes constituting each blockchain. Here, a node is a computing subject (for example, a server) that can store the blocked data and consequently verify the data integrity of the blockchain.

Therefore, for example, a bitcoin network connected to many nodes can be considered a public blockchain, and a blockchain used internally in the corporate infrastructure and a limited number of nodes can be considered a private blockchain.

As an inherent problem of the private blockchain defined by this distinction, limited verification capability by a small number of nodes is increasingly being presented as a problem. In order to solve such a verification capability problem, anchoring is defined and proposed in the present invention.

For the definition of anchoring, for example, in a private blockchain, it is possible to periodically store information in the private blockchain in a public blockchain with a higher verifiability and a higher number of nodes. The integrity of the chain can be additionally verified, and this behavior can be defined as anchoring. Here, an action may mean that the computing subject exchanges meaningful information with other computing subjects through a specific computing means.

In a similar sense, the verification capability of the system that makes up the blockchain is defined as the hierarchical order of the blockchain, and a blockchain with a high hierarchical order (for example, a public blockchain) is a blockchain with a low hierarchy (for example, a private block). Chain) can be defined as being at a higher level. In this sense, the definition of anchoring can also be regarded as storing information of an arbitrary blockchain in a higher-level blockchain separated from an arbitrary blockchain. As a result, it is possible to increase the reliability of arbitrary blockchain information through such anchoring.

Anchoring has a strong aspect of information verification, but if the function of a relay or gateway node to be described later is reinforced, it also provides the function of an interoperation system that exchanges information between separate blockchain systems. can see.

An anchoring technique based on a block chain according to an embodiment of the present invention comprises the steps of (a) recording information to be exposed generated using user information in the first blockchain network holding the blockchain, and (b) And storing the information to be exposed recorded in the first blockchain network in a second blockchain network possessing an upper blockchain. That is, the second blockchain network according to an embodiment of the present invention is a higher blockchain-holding server than the first blockchain network, and receives information to be exposed from the first blockchain network. In addition, it is possible for the server to exist in addition to the first blockchain network and the second blockchain network as necessary.

The blockchain refers to a block chain with a relatively small number of nodes as a private blockchain, and a public blockchain with a relatively large number of nodes. The first block chain network and the second block chain network according to an embodiment of the present invention can be applied by replacing them with a private blockchain and a public blockchain, respectively.

In the step (a), the first blockchain network holding the blockchain converts the summarized content or part of the current content into data of a fixed length. At this time, the information converted into data of a fixed length is called information to be exposed, and the information to be exposed is stored in a block chain in units of individual information such as transactions, transactions, events, etc. In other words, the information to be exposed converted from one blockchain system is stored as a higher blockchain system as well as another blockchain system to increase reliability.

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

In this way, the anchoring method can be defined as an offline anchoring method by fixing the data to be anchored based on the state of the blockchain. The main difference between the offline anchoring and other online/dynamic anchoring methods is 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.

Also, offline anchoring is also referred to as static anchoring.

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

In addition, if anchoring occurs frequently, there is a problem that traffic between block chains occurs frequently and the user's experience speed decreases.If anchoring occurs too little, the stability of the private blockchain decreases, resulting in unreliable results. Accordingly, according to an embodiment of the present invention, if the storage is performed according to a certain period or a specific condition, the user's experience speed does not decrease and reliability may be increased.

3 is a flowchart illustrating an anchoring method when information to be exposed is implemented as hash information according to an embodiment of the present invention. Referring to FIG. 3, a process for performing an additional verification process by storing information on a private blockchain will be described in detail according to embodiments.

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

When the hash information is combined with at least one or more hash information, if an object to be verified is explicitly revealed, it is possible to immediately confirm and announce whether a specific message or event has occurred, and to perform anchoring at the same time. . The hash information shown in FIG. 3 is an example of information to be exposed according to an embodiment, and any information to be exposed may be any information other than hash information.

In addition, as an embodiment, when two accounts exchange messages, only a portion of the amount is combined and transmitted as information to be exposed, and the remaining general conversation messages may be excluded without being combined as information to be exposed. In another embodiment, when signing a contract on the Internet, only necessary information is selected among contract information, combined with information to be exposed, and transmitted, and other general items may be excluded without combining.

This method can be defined as online anchoring.

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

This anchoring method can be defined as a dynamic anchoring method.

In one embodiment, in the dynamic anchoring, it is possible to select a viewpoint and an object of anchoring. In other words, if notarization is required in the middle of a transaction or conversation, it is possible to immediately record the transaction or conversation in the public blockchain by anchoring.

In addition, in an embodiment, in the case of information exchanged between two people who wish to exchange a message, a message determined to be important among the information exchanged may be verified in a manner of delivering while anchoring is performed. That is, as another example, in the case of applying the blockchain to voting, the user will only anchor the process of checking the result of the voting, or the process of voting itself as well, or the result of the voting may be unclear according to the pre-set conditions. It is possible to set whether or not to anchor the voting process only when it becomes available.

That is, the dynamic anchoring can secure stability by exposing desired information to the public blockchain at any time.

At first glance, both online anchoring and dynamic anchoring are common in that they do not anchor fixed information to be exposed based on state, but for example, online anchoring changes the data to be anchored (information to be exposed) by changing the user's settings. On the other hand, in dynamic anchoring, the data to be anchored can be dynamically changed to satisfy a specific performance according to the situation of a specific blockchain. As an example of implementing dynamic anchoring, if the response speed is too slow considering both the integrity of the system and the response speed of the system, the data or period to be anchored is changed to a direction with a high system response speed, Likewise, when the integrity of the system is very important, the data to be anchored and the period can be set to a strong degree.

In addition, 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. Referring to FIG. 2, an anchoring using a reflector will be described in more detail.

Referring to FIG. 2, if a message is dynamically determined to be stored through anchoring in one account or one contract, the user can transmit through an upper blockchain through an outbound relay. In other words, the reflector is a device that duplicates and retransmits input information to the sender, operates on the upper blockchain, and plays a role of notifying by replicating information received from the outbound relay to the inbound relay. .

At this time, the relay is composed of an outbound relay and an inbound relay. The outbound relay is a relay that transmits a message to an upper blockchain system to support the anchoring, and the inbound relay is a relay that transmits a message from an upper blockchain system to a lower blockchain system. to be. In the above embodiment, the relay is provided to deliver information to be exposed, and can be implemented in various devices such as a server, a S/W program, and a cloud service, depending on the embodiment.

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

A relay according to an embodiment of the present invention delivers a message by separating an outbound relay and an inbound relay, but according to another embodiment, only one relay is configured. It is also possible to perform both outbound relay and inbound relay functions.

4 is an embodiment of an outbound relay and an inbound relay according to an embodiment of the present invention. A specific embodiment of the outbound relay and inbound relay will be described in more detail with reference to FIG. 4.

Accounts for storing contract information are formed in the first blockchain network including the blockchain system and the second blockchain network. 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 conversion module is configured as one, and acts as an inbound relay and an outbound relay at the same time.

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 an input of the information. When the connection module detects the input of corresponding information, it can 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 is converted into a structure usable in the second blockchain network in the blockchain transaction information conversion module. In other words, it transforms into an information structure corresponding to the second blockchain network.

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

The present invention is not limited to the above-described embodiments, and the scope of application thereof is diverse, as well as anyone with ordinary knowledge in the field to which the present invention belongs without departing from the gist of the present invention claimed in the claims. Of course, various modifications are possible.
