Description

Block Chain Participation Control System by Estimating Transaction Value

The present invention relates to a block chain system, and more particularly, to a block chain participation control system through transaction value estimation that improves computing performance by adjusting participation priority or participation rate of a block chain based on a transaction value.

As is well known, a block chain is also called a public transaction book and is a technique to prevent hacking that may occur when trading with virtual currency. In the case of existing financial companies, transaction logs are kept on a centralized server, while block chains send transactions to all users participating in the transaction, and are used to prevent counterfeiting of data against each transaction.

The block chain is applied to a bit coin, which is a typical online virtual currency. Bitcoin transparently records transactions on a book that anyone can read, and several computers using bit coin verify this record every 10 minutes to prevent hacking.

Bitcoin is designed to work in a fully decentralized manner with P2P without a server controlling the system. In addition, anyone can use the system without having to register a user who can use the money separately. Since there is no server to register, each user uses the public key as a sort of one-time account number. When a user A signs a specific message with a private key known only to him, the third party uses the public key to determine whether the signature is signed with a secret key corresponding to the pair of this public key (ie, It can be authenticated.

For example, if A transfers money to B, in an existing banking system, B first opens an account in the bank, and A notifies the bank name and account number. A transfers money to his account through his bank, which is guaranteed by both banks. However, in the bit coin, B generates a public key and a private key, passes the public key to A, and keeps the private key securely on his computer. A creates a check with B's public key as its recipient and sends it to the entire P2P network. All bitcoin users receive this check, but only those who have B's private key can use this check later. Anyone can verify that B is the person to receive this check using the public key encryption algorithm mentioned above.

The most important part of a bit coin system is this transaction. It is a bit coin system that it is possible to generate bit coin, supply currency, and exchange bit coin with each other. The transaction details of the bit coin are a kind of check that tells which address the money is sent to, and since this check can be issued by anyone, the bank does not need a bank, and it is necessary for the bank to check who is the owner of the check none. Bitcoin is a virtual currency system with no bank, no bank account, and only checks exchanged between individuals.

All checks that have been issued in the past, that is, the repository containing all transaction details, are called block chains in the bit coin. Block chains are all peers of a P2P network (peers, computers or users of P2P networks). If this block chain contains all transactions, you can check the block chain to see if the check issuer is eligible to issue checks, ie, checks.

In order to be able to issue a check to someone, I must have previously received and paid for that amount somewhere. Thus, a check issued by the bit coin contains a link referencing the previous check, and the user follows that link to check whether the amount the previous check contains is greater than the amount issued by the new check. Every bitcoin user connects to the P2P network and keeps a copy of the same transaction book. It is up to the user to write down the new transaction details in the transaction book. They gather every 10 minutes to update the transaction books to the latest.

If you write down your recent transaction history, all the bit coin users will take back the newly created transaction book. Repeat this process approximately every 10 minutes. At this time, the bundle of transactions made every 10 minutes is called "block".

The block chain refers to the entire transaction book in which the block is assembled. BitCoin has built up a block chain of all trades that have been made since January 2009. Even now, worldwide bit coin users are meeting in the bit coin network every 10 minutes to extend the block chain.

However, such a conventional block chain system has a problem of consuming resource and transaction time by using more storage and computing performance than necessary even in the case of a simple transaction by engaging nodes of the same rank or quantity for all transactions.

BRIEF DESCRIPTION OF THE DRAWINGS The advantages and features of the present invention, and the manner of achieving them, will be apparent from and elucidated with reference to the embodiments described hereinafter in conjunction with the accompanying drawings. The present invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete and will fully convey the concept of the invention to those skilled in the art. To fully disclose the scope of the invention, and the invention is only defined by the scope of the claims.

The terminology used herein is for the purpose of illustrating embodiments and is not intended to be limiting of the present invention. In the present specification, the singular form includes plural forms unless otherwise specified in the specification. The terms " comprises "and / or" comprising "used in the specification do not exclude the presence or addition of one or more other elements in addition to the stated element. Like reference numerals refer to like elements throughout the specification and "and / or" include each and every combination of one or more of the elements mentioned. Although "first "," second "and the like are used to describe various components, it is needless to say that these components are not limited by these terms. These terms are used only to distinguish one component from another. Therefore, it goes without saying that the first component mentioned below may be the second component within the technical scope of the present invention.

Unless defined otherwise, all terms (including technical and scientific terms) used herein may be used in a sense that is commonly understood by one of ordinary skill in the art to which this invention belongs. In addition, commonly used predefined terms are not ideally or excessively interpreted unless explicitly defined otherwise.

The terms spatially relative, "below", "beneath", "lower", "above", "upper" And can be used to easily describe a correlation between an element and other elements. Spatially relative terms should be understood in terms of the directions shown in the drawings, including the different directions of components at the time of use or operation. For example, when inverting an element shown in the figures, an element described as "below" or "beneath" of another element may be placed "above" another element . Thus, the exemplary term "below" can include both downward and upward directions. The components can also be oriented in different directions, so that spatially relative terms can be interpreted according to orientation.

The block chain controller (BCC) according to the present invention has storage and computation capabilities, but since it is not reasonable to operate all the resources for one transaction, the value of each transaction And actively adjusts the size of the intervention. This can make energy consumption and transaction time predictable.

In particular, the BCC is a block chain implementation on the network side. Currently, block chains are vulnerable to attacks because they do not have a controller or central control system, and if they occupy more than half of the total, they can fix their contents. Therefore, if the concept of a block-chain controller is introduced and implemented as a network device as in the embodiment of the present invention, the user can not easily access the device, and since the controller processes approval or decision algorithm, security can be ensured. The data can be stably maintained.

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

FIG. 1 is a block diagram illustrating a block chain participation control system through a transaction value estimation according to an embodiment of the present invention. FIG. 2 is a flowchart illustrating a control operation according to an embodiment of the present invention.

As shown in the figure, the block chain participation control system through the transaction value estimation according to an embodiment of the present invention includes a user terminal 100, a communication network 200, nodes N1, N2, N3 300, a gateway 400, And a management server 500.

As illustrated, the plurality of unit nodes N1, N2, and N3 300 may include at least one of the Internet, a mobile communication network, and a Low Power Wide Area Network (LPWAN) including a block-chain cloud. A gateway (GW) 400, and the like, and may include a management server 500 for updating, data collection, minimum management, etc., as needed.

However, the entire block chain system can be configured to be operable between the nodes N1, N2, and N3 without the management server 500. [ The number of all unit nodes (hereinafter referred to as "nodes" or " unit nodes "in combination) is shown as a certain number for convenience of explanation, but the number thereof is numerous and is not particularly limited.

Although each unit node (N1, N2, N3) differs in the size of each component involved, connection method, etc., it basically includes a block chain, and a unique public key and a private key And provide them.

More particularly, the present invention relates to an apparatus and method for transmitting data in a unit node N1, N2, and N3 (300) by connecting a plurality of unit nodes N1, N2, and N3 300 to at least one of a wired and wireless communication network Wherein the unit 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 based on a block chain in which individual blocks recording the transaction history are linked in a chain form (S100).

The present invention further includes a user terminal 100 connected to the unit nodes N1, N2, and N3 300 through the wired / wireless network 200. [

In step S110, the user terminal 100 differentiates the participation priority or the participation rate of the block chain of the unit nodes N1, N2, and N3 300 based on the stepwise transaction value.

In an embodiment of the present invention, one or more block chain controllers may be further included. The block chain controller is configured with at least one 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 block-chain controller nodes N1, N2, and N3 (300).

And the private key list of each of the block-chain controller nodes N1, N2 and N3 300, and combines the private key of the node corresponding to the specific public key selected from the inherent public key list with the private key of the block- To the block chain controller nodes N1, N2 and N3 (300).

The block chain controller nodes N1, N2 and N3 300 have storage and arithmetic capabilities and are capable of determining the participation priority or the participation quantity of the block chain of the unit nodes N1, N2 and N3 300 based on the stepwise transaction value. (Step S110).

The user terminal 100 and the node N1 exchange the hash values when the mutual communication is started, thereby checking mutual hash values. If they are different, it treats them as an error and cancels the connection. At this time, if too many nodes 300 participate in one transaction and approve and deny, the network is overloaded. To prevent this, for example, a one-dollar transaction and a ten-dollar transaction are differentiated The dollar sign controls only one or two nodes. In other words, it is to adjust the scale of peer participation through value estimation. At this time, since there is a server serving as a map for finding the peer, it is possible to provide a process of selecting an intermediate path.

As described above, not all transactions have the same importance, so it is not wise to use more storage and computing performance than is necessary for simple transactions. Thus, the present invention can shorten resource consumption and transaction time by prioritizing transactions based on the value of a transaction and determining participation of the block chain accordingly.

For example, a simple transaction can be completed with only one adjacent block verification and authentication. On the other hand, in the case of the first level, only the adjacent block (the first hop block) can participate in a slightly complicated transaction. Finally, in the case of the most complex and valuable transactions, two, three or more adjacent blocks (second or more hop blocks) may participate.

At this time, the transaction value, the number of nodes to participate, the position of the final node, and the like can be determined using a predetermined reference value preset in the user terminal 100.

1 and 2, the user terminal 100 may determine that only one adjacent unit node N1 participates in the block chain when one transaction is determined to have a transaction value of a first step S120 to S130).

In addition, when one transaction is judged as the transaction value of the second stage, one adjacent N th unit node N 1 and the N + 1 th unit node N 2 adjacent to the N th unit node N 1, It is possible to decide to participate in the chain (steps S140 to S150).

In addition, when another transaction is judged as the transaction value of the third stage, one adjacent N th unit node N 1 and the (N + 1) th unit node N 2 adjacent to the N th unit node N 1, 2 unit nodes N3 adjacent to the (N + 1) th unit node N2 may be sequentially included in the block chain in operation S160 through S170.

According to another embodiment, the block-chain controller node 300 determines that only one adjacent block-chain controller node N1 300 participates in the block chain when one transaction is judged as the transaction value of the first stage (Steps S120 to S130).

(N2) adjacent to the Nth block-chain controller node (N1), and a controller node (N2) adjacent to the Nth block-chain controller node (N1) May participate in the block chain (steps S140 to S150).

In addition, when another transaction is judged to be a transaction value of the third stage, an N-th block-chain controller N1 adjacent to the N-th block-chain controller node N1, N2 blocks adjacent to the (N + 1) th unit block chain controller nodes N2 and controller nodes N3 in the (N + 2) th block chain chain N3 can be determined to participate in the block chain sequentially (S160 to S170 step).

Here, block chain participation means that the block must consume the associated energy, storage and computing capabilities.

The end user (user) can make the transaction valuable or inexpensive based on requirements and priorities. Therefore, transaction costs must be different for different cases, which is only guaranteed by how many blocks are involved in a particular transaction.

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

As described above, the current block chain has all the replicas of all data users, so there are thousands or even tens of thousands of duplicated data. To remove it, the controller has all the data and the user does not have any information about the block chain. Since the controller forms a mesh through P2P connection, it is able to perform block chain service in synchronization with each other.

Technically, a block chain is a sequence of blocks and their chains are replicated to all of them. When doing an integrity check between blocks in a block chain, all blocks have hash values just before it (such as a fingerprint of data). If the data is changed, the hash value and the data do not match and the data is invalid. Users have data fingerprints. You can see if you have hashes that you have created or related to yourself, and if the data is manipulated on the block chain side, you can check to see if it has been tampered with. The block chain controller has the actual transaction history (for example, the fact that a has sent a b to a bank).

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

Because existing block chains are difficult to communicate in real time, it was difficult to integrate them into other areas of communication security other than those related to financial institutions or contracts. The present invention enables real-time communication because the block chain controller knows the information about the users connected to it, knows the counterpart controller, and mutually authenticates each other.

That is, the block-chain controller checks the integrity of the user's activity and verifies that it is safe. B needs a decryption key for the data sent by A, and B can check whether the key is wrong.

Also, the diagram shown in FIG. 1 shows the location where the BBC may exist. It is possible to connect the block chain controller to the external network (Internet) instead of the cloud by making the BCC cloud and go down to the end terminal of the user. In case of attaching to the cellular network equipment, software protocol can be created. Lt; / RTI >

Depending on where it is implemented, there may be a difference in access speeds, and BBC independent servers or PCs are integrated into one network device, eliminating the need for space and less energy. Cellular networks cost money every time you use it, so you can minimize it if you load it in Innovbi. Therefore, if the block chain controller of the present invention is used, the physical gap can be reduced because the BCC control is performed instead of attaching directly to each other.

The embodiments of the present invention described in the present specification and the configurations shown in the drawings relate to the most preferred embodiments of the present invention and are not intended to encompass all of the technical ideas of the present invention so that various equivalents And variations are possible. It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined in the appended claims. , And such changes are within the scope of the claims.
