Description

Involvement Control System of Block Chain Controller based on Transaction Value}

The present invention relates to a blockchain system, in particular, using a blockchain controller having storage and computing power to estimate the transaction value to improve the computing performance by adjusting the participation priority or the quantity of participation of the blockchain based on the transaction value. It relates to a blockchain controller participation control system.

As is well known, blockchain is also called public trading ledger and is a technique to prevent hacking that can occur when trading in virtual currency. Traditional financial firms keep transaction records on a centralized server, while blockchain sends transaction details to all users participating in a transaction and checks each transaction for counterfeiting.

Blockchain is applied to Bitcoin, a representative online virtual currency. Bitcoin transparently records transaction details in a book that anyone can read, and several computers using Bitcoin verify this record every 10 minutes to prevent hacking.

Bitcoin is designed to work in a fully distributed fashion in a peer-to-peer fashion without a server controlling the system. In addition, the system allows anyone to use the system without having to register a user who can use money. Since there is no server to register, each user uses the public key as a kind of one-time account number. If a user, A, signs a message with a private key that only he knows, a third party uses the public key to sign the signature with the private key that corresponds to the pair of public keys (that is, whether the user A is correct). It can be authenticated.

For example, if A delivers money to B, in the existing banking system, B first opens an account at the bank and tells A the bank name and account number. A transfers money through his bank to B's account, and the transaction is guaranteed by both banks. However, in Bitcoin, B generates a public key and a private key, delivers the public key to A, and keeps the private key securely on its computer. A writes a check that accepts B's public key and sends it to the entire P2P network. All Bitcoin users will receive this check, but the only person who can use it later will be the one with B's private key. Anyone can verify that B is the recipient of this check using the public-key cryptographic algorithm mentioned earlier.

The most important part of the Bitcoin system is this transaction. It is all about the Bitcoin system that generates Bitcoin to provide currency and allow Bitcoin to be exchanged between individuals. Bitcoin's transaction history is a kind of check that tells you which money is being sent to which address, and since this check can be issued by anyone, you don't need a bank and you need to check who owns the check. none. In Bitcoin's virtual currency system, there are no banks, no bank accounts, and only personal checks.

In Bitcoin, all the checks issued in the past, that is, the storage containing all the transaction history, are called blockchain. The blockchain is owned by every peer (peer, computer or user of P2P network) in the P2P network. If the blockchain contains all the transaction details, you can check the blockchain to see if the check issuer has a balance, that is, whether it is eligible to issue a check.

Before I can issue a check to anyone, I must have received and retained that amount of check somewhere. Therefore, a check issued by Bitcoin contains a link referring to a previous check, and the user follows the link to verify that the amount the previous check contains is greater than the amount issued by the new check. All Bitcoin users access the P2P network and keep copies of the same transaction book. It is also up to the user to write the new transaction details into the transaction book. They meet every 10 minutes to keep their books up to date.

Once you've written down your recent transactions, all your Bitcoin users will take them back to you. Repeat this approximately once every 10 minutes. The bundle of transactions that are made every 10 minutes is called a "block."

Blockchain refers to the entire transaction book in which blocks are collected. Bitcoin has accumulated all transactions made in the blockchain since January 2009. Even today, Bitcoin users around the world are meeting on the Bitcoin network every 10 minutes to extend their blockchain.

However, such a conventional blockchain system has a problem of wasting resources and transaction time by using more storage and computing power than necessary even in a simple transaction by involving nodes of the same rank or quantity for all transactions.

Advantages and features of the present invention and methods for achieving them will be apparent with reference to the embodiments described below in detail with the accompanying drawings. As those skilled in the art would realize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. It is provided to fully inform the scope of the invention to the invention, which is defined only by the scope of the claims.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. In this specification, the singular also includes the plural unless specifically stated otherwise in the phrase. As used herein, "comprises" and / or "comprising" does not exclude the presence or addition of one or more other components in addition to the mentioned components. Like reference numerals refer to like elements throughout, and "and / or" includes each and all combinations of one or more of the mentioned components. Although "first", "second", etc. are used to describe various components, these components are of course not limited by these terms. These terms are only used to distinguish one component from another. Therefore, of course, the first component mentioned below may be a second component within the technical spirit of the present invention.

Unless otherwise defined, all terms used in the present specification (including technical and scientific terms) may be used in a sense that can be commonly understood by those skilled in the art. In addition, terms that are defined in a commonly used dictionary are not ideally or excessively interpreted unless they are clearly specifically defined.

The spatially relative terms " below ", " beneath ", " lower ", " above ", " upper " It can be used to easily describe a component and its correlation with other components. Spatially relative terms are to be understood as including terms in different directions of components in use or operation in addition to the directions shown in the figures. For example, when flipping a component shown in the drawing, a component described as "below" or "beneath" of another component may be placed "above" the other component. Can be. Thus, the exemplary term "below" can encompass both an orientation of above and below. Components may be oriented in other directions as well, so spatially relative terms may be interpreted according to orientation.

Although the block chain controller (BCC) according to the present invention has storage and computing power, it is not appropriate to operate all resources for one transaction, so it is worth each transaction based on transaction priority. Estimate the size of the intervention to proactively plan how to use the resources. This can make it possible to predict energy consumption and transaction time.

In particular, the BCC is to implement a blockchain on the network side. Currently, blockchain is vulnerable to attack because there is no controller or central control system, and if it occupies more than half, there is a problem that the entire contents can be modified. Therefore, if the concept of a blockchain controller is introduced and implemented as a network device, as in an embodiment of the present invention, the user may not easily access it, and thus the security may be secured because the controller processes the approval or decision algorithm. It can keep data stable.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a block diagram showing a blockchain controller participation control system through transaction value estimation according to an embodiment of the present invention, Figure 2 is a flow chart showing a control flow according to an embodiment of the present invention of FIG.

As shown, the blockchain controller participation control system through transaction value estimation according to an embodiment of the present invention, the user terminal 100, the communication network 200, unit nodes N1, N2, N3 (300), gateway ( 400) and the management server 500.

As shown, a plurality of unit nodes (N1, N2, N3) (300) includes or is connected to at least one of the Internet, a mobile communication network, a low power wide area network (LPWAN) including a blockchain cloud It is made by interconnecting the gateway (GW) 400, etc., may include a management server 500 for updating, data collection, minimal management, etc. as necessary.

However, the entire blockchain system may be configured to operate between the unit nodes N1, N2, and N3 300 without the management server 500. Although the total number of unit nodes is shown as a certain number for convenience of description, the number is numerous and there is no particular limitation.

 Although each unit node (N1, N2, N3) differs in the size and connection method of each component involved, it basically includes a blockchain and uses a unique public and private key based on the existing blockchain for the connected node. Create and provide.

More specifically, the present invention is a plurality of unit nodes N1, N2, N3 (300) is connected to at least one of the wired and wireless communication network 200, the data of the unit nodes N1, N2, N3 (300) A blockchain system for mutually verifying integrity between the plurality of nodes 300, wherein the nodes N1, N2, and N3 300 are directly or indirectly connected to at least one of the wired and wireless communication networks 200. A unique public key and a private key are generated and provided on the basis of a block chain in which individual blocks having recorded histories are linked in a chain form (step S100).

The present invention further includes one or more blockchain controllers. The blockchain controller is composed of one or more of the plurality of unit nodes N1, N2, and N3 300. That is, at least one of the plurality of unit nodes is preferably composed of blockchain controller nodes N1, N2, and N3 (300).

Each of the blockchain controller nodes N1, N2, and N3 300 has a unique public key list and combines its own private key with respect to a node corresponding to a specific public key selected from the unique public key list. The blockchain controller nodes N1, N2, and N3 300 are transmitted to the blockchain controller nodes.

The blockchain controller nodes N1, N2, and N3 300 have storage and computing power, and the participation priority or the quantity of participation of the blockchains of the unit nodes N1, N2, and N3 300 based on the transaction value in stages. Determine by differentiating (step S110).

When the mutual communication starts, the blockchain controller nodes N1, N2, and N3 300 exchange hash values with each other to check mutual hash values. If they are different, treat them as an error and cancel the connection. At this time, if the entire blockchain controller node 300 that manages the blockchain approves and rejects one transaction, the network is overloaded, so as to prevent this, for example, a $ 1 transaction and a $ 10 transaction By differentiating the transaction, you control only one or two blockchain controller nodes worth $ 1. In other words, value estimating scales the peers' involvement. In this case, since there is a server serving as a map for finding a peer, a process of selecting an intermediate route may be provided.

As mentioned above, not all transactions have the same importance, so it is not wise to use more storage and computing power than is required for simple transactions. Thus, the present invention can reduce resource energy consumption and transaction time by prioritizing transactions based on the value of the transaction and determining the participation of the blockchain of blockchain controller nodes accordingly.

For example, a simple transaction can be completed only with verification and authentication of one adjacent blockchain controller node (hereinafter abbreviated as BCC). At the first level, on the other hand, only the adjacent BC (first hop BCC) can participate in a slightly complex transaction. Finally, in the case of the most complex and valuable transactions, two, three or more adjacent BCCs (second or more hop BCCs) may participate.

At this time, the transaction value, the number of nodes to participate, the position of the final node, etc. may be determined using a specific reference value preset in the blockchain controller node 300.

Referring to FIGS. 1 and 2, when one transaction is determined to be a transaction value of one step, only one adjacent blockchain controller node N1 300 participates in the blockchain. Can be determined to (steps S120 ~ S130).

In addition, when one transaction is determined as the transaction value of the second stage, one adjacent N-th blockchain controller node N1 and the N-th blockchain controller node adjacent to the N-th blockchain controller node N1. (N2) may determine to participate in the blockchain (steps S140 to S150).

In addition, when another transaction is determined to have a transaction value of three stages, an N-th blockchain controller N1 adjacent to the N-th blockchain controller node N1 and the N-th blockchain controller node N1 are adjacent. Nodes N2 and the N + 2th blockchain controller nodes N3 adjacent to the N + 1th blockchain controller nodes N2 may be determined to sequentially participate in the blockchain (S160 to S170). step).

Here, participation in the blockchain means that the block must consume associated energy, storage and computing power.

End users (users) can make a transaction worth or cheaper based on requirements and priorities. Therefore, transaction costs must be different in different cases, and this is only guaranteed by how many blocks are involved in a particular transaction.

The time required for a particular transaction may vary depending on the priority and participation of the block.

As mentioned above, the current blockchain has all the data for all the users, so there are thousands of users with duplicate data. To remove it, the controller has all the data and the user doesn't have any information about the blockchain. Since the controller forms a mesh through the P2P connection, the block chain service can be synchronized with each other.

Technically, a blockchain is a sequence of blocks and the chains are replicated to all. In blockchain integrity checking, every block has a hash value just before it (= like a fingerprint of data). If the data is changed, the data is invalid because the hash value and the data do not match. Users have a data fingerprint. If you have hashes that you create or are associated with, you can check if the data has been manipulated on the blockchain side to see if it has been manipulated or not. The blockchain controller has the actual transaction history (e.g. the fact that a sent money to b in the case of a bank).

That is, the user performs data integrity checks, and the BBC is responsible for hash value checks, decryption key checks, and data management.

Existing blockchains have difficulty in real-time communication, making it difficult to integrate them into other communication security fields other than authentication of financial institutions or contracts. The present invention enables real-time communication because the blockchain controller knows information about users connected to it, the other controller also knows each other, and can mutually authenticate each other.

In other words, the blockchain controller looks at the history of the user's activity and verifies whether he is safe or not. B needs a decryption key for the data that A sends, but B can check whether the key is wrong.

Also, the diagram shown in FIG. 1 shows where the BBC can be present. Since the BCC cloud is formed and descends to the end terminal of the user, the blockchain controller is connected to the external network (internet) instead of the cloud, and if it is attached to cellular network equipment, the software protocol can be written, so INNODEB itself functions as a blockchain controller. Can have

Depending on where it is implemented, access speeds can vary and are integrated into one network device without the need for a BBC independent server or PC, resulting in less space and less energy. Cellular networks cost you money each time you use them, so you can minimize them by loading them on Innodeby. Therefore, when the blockchain controller of the present invention is used, it is possible to reduce the physical gap because the peers are not directly attached to each other but are subjected to BCC control.

The embodiments shown in the present specification and the configuration shown in the drawings are related to the most preferred embodiments of the present invention and do not cover all of the technical idea of the present invention, and various equivalents may be substituted for them at the time of filing. It should be understood that there may be variations and variations. Accordingly, the present invention is not limited to the above-described embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention as claimed in the claims. Such changes will fall within the scope of the claims.
