Abstract

For transacting and exchanging current cryptocurrencies, a specific service provider such as an existing middle man installs a server of high capacity and high performance to store and maintain transaction information and all customer information at an exchange site for mediating all exchanges and transactions so as to largely generate financial accidents caused by attacks from an external hacker or conspiracies of inner employees. A centralized transaction is also incompatible with fundamental spirit of the cryptocurrency pursuing peer-to-peer. Therefore, the present invention relates to an apparatus for allowing a cryptocurrency owner to support a contract processing and trading of the cryptocurrency and accompanying contracts in a completely decentralized manner based on a blockchain and a method thereof.

Description

[0001] APPARATUS AND METHODS FOR DECENTRALIZED TRANSACTIONS PROCESSING AND TRANSMITTING IN A BLOCKCHAIN PLATFORM [0002]

The present invention relates to a process and a method for supporting the processing and sale of a transaction of a cryptographic currency and a contract thereunder in a block decentralized manner by a Cryptocurrency owner based on a block chain .

Bitcoin (Peer-to-Peer Electronic Cash System), which is a white paper on the principle and operation method of cryptography, was released by Nakamoto Satoshi in October 2008, After releasing the software developed for the general public, it has now opened the era of cryptography. In addition to mining the cryptographic currency, it enables the transfer or collection of money, the transaction of the existing legal currency (Fiat Currency) and the cryptographic currency, and the transaction of different cryptographic closure.

Though remittance and settlement between decentralized peer computers have become a reality, the exchange for the sale and purchase of cryptography, the exchange between cryptographic money and existing legal money, As it is still realized and operated in a centralized manner, a certain exchange is heckled by a hacker and the important information of the customer who has joined the exchange is seized, and the exchange is bankrupt or distrust due to frequent accidents It is a situation. The present invention corresponds to a core technology for solving the problem of a centralized exchange by applying a de-centralization method on the basis of the operation of a cryptographic currency to a currently operated exchange.

In order to trade foreign exchange exchanges, stocks and bonds, foreign exchange exchanges, stock exchanges, and banks are required to deposit and settle transactions in a centralized organization (or Man in the middle) that acts as intermediary between the buyer and the seller middle) Exchange exists.

In a centralized exchange, banks, stock exchanges, insurers, foreign exchange markets, etc., manage the information and accounts of the customers they want to trade to perform their functions. Even in the case of cryptography that provides decentralized processing between peer-to-peer computers that are spatially separated from each other by a peer-to-peer concept, rather than a single large central server, But rather through a centralized form of exchange. This is because it is difficult to find people who want to trade passwords rather than a problem of specific technology, so buyers and sellers gather together in the exchange market to buy exchanges that are traded according to buying and selling prices. If you want to use the Internet in the early days before the Internet is popularized, if you visit a portal site rather than visiting a specific site, most of the information that the visitor wants is here, As a matter of fact, most cryptographic money holders visit the exchange site and conduct transactions and exchanges with sellers and buyers such as functions in the marketplace.

A centralized exchange can attack a specific single computer by a hacker, causing a drop in service quality or service quality due to the failure or delay of the corresponding computer. However, the management is easy and the operation of the system is simple There is an advantage. Currently, passwords are known to be secure, but because of the vulnerability to the operation and management of the central exchange, the secret key is stored in the wallet, which is important information of the subscriber. If information about the subscriber's wallet is hacked, Unlike existing exchanges such as stock exchanges, there are cases where they are completely stolen.

Although exchanges are hacked by hackers, exchanges such as Mt. Cox in Japan in 2014 are banned due to lack of security management of exchanges or moral hazard to customers. In recent years, Although the exchange has been hacked, it is implicitly known that it is important to trust, which is the characteristic of the financial industry, so it is shameless and internally confidential. Also, information on the exchange rate between the existing cryptographic currency and the legal currency, which is information from the outside of the exchange, and the exchange rate applied when exchanging and exchanging different types of cryptographic keys, may be distorted. The price of cryptographic money is so volatile that the exchange's server becomes obstructed at the moment when its customers buy or sell, or temporarily intercepts access from outside to make profit at the relevant moment under the conspiracy of employees of the exchange Can be expected. Even in this situation, continuous transactions can be provided without being affected.

Exchange rates announced on the current cryptographic exchange are different for each transaction site. There is a need for a way to abolish these different exchange rates and trade at a worldwide exchange rate.

The inventor of the present invention, unlike the existing centralized cryptographic exchange, does not store the important information of the cryptographic money holder in the exchange but rather needs to own and manage the holder himself, and the information is not stored in the exchange, The present invention has been completed based on research efforts to find a technical solution to whether or not to implement a technique for increasing the trust of the user.

Currently, there are no decentralization transactions for cryptocurrency such as Bitcoin, Ethereum and Litecoin, and Iota, as well as for existing stock and bond transactions, foreign exchange transactions, It can also be applied to bank transactions where it is possible to conduct safe financial transactions through decentralization transactions.

On the other hand, other unspecified purposes of the present invention will be further considered within the scope of the following detailed description and easily deduced from the effects thereof.

In order to accomplish the above object, a first aspect of the present invention is a block chain trading apparatus characterized in that a mobile communication terminal trades offer information transmitted through a peer-to-peer communication network.

A second aspect of the present invention features a block-chain trading method characterized in that the mobile mobile terminal trades offer information transmitted over a peer-to-peer communication network.

According to the present invention, the wallet information on the encrypted currency held by the currency holder is directly managed by the money holder without storing the information on the encrypted currency, thereby providing a continuous transaction irrespective of the obstacle and the security accident caused by the system hacking on the exchange.

Currently, the exchange rate provided by the cryptographic exchange is also different, so the cryptographic holders are able to trade through various exchanges by using the regional difference. De-centralization transactions can bind all exchanges that are scattered around the world into a single integrated exchange concept, so that those trading in cryptography must go to a particular exchange to navigate to sell and buy prices, Each exchange must have a separate account, which can increase the risk and vulnerability of account management. In the case of remittance and payment between exchanges even if they have the same cryptographic currency, the related costs are additionally added, so that it is expected that the cost for the holder of the cryptographic currency is increased due to joining various sites. However, .

In addition, unlike the way in which a cryptographer stores and processes information according to buying and selling at a centralized exchange, information necessary for trading is exchanged, collected, and sorted by each peer in an individual's smartphone corresponding to the peer To provide the same functionality as a large central server in a smartphone with limited processing power and storage space.

It is made possible through the wireless mobile communication terminal device possessed by the fully decentralized cryptographic currency owner for the transaction of the cryptographic currency on the block chain basis. In addition to the cryptographic currency, in the case of trades such as legal money, stocks and bonds Extended support is also available.

The effects described in the following specification and the provisional effects expected by the technical features of the present invention and the provisional effects thereof described in the specification of the present invention, even if not explicitly mentioned here, Quot ;, which is incorporated herein by reference in its entirety.

In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may obscure the subject matter of the present invention.

Figure 1 shows the concept of a current centralized exchange. The drawing shall be signed by the cryptographic holder, the stock and bond holder, and the legal currency owner as a member or customer of the exchange. The centralized exchange stores and manages the price, buy and sellers' information, the exchange rate for buying and selling for the objects to be traded. In addition, based on the transaction information, the member of the exchange provides analysis data such as various charts and trends, and manages the information of the affiliated customer or member. In the case of cryptography, it is stored and managed in the form of a wallet containing the secret key. In addition, exchange rates and other data provided from outside the exchange are also stored and managed on the exchange.

FIG. 2 is a diagram illustrating an example of a preferred embodiment of the present invention in which a decentralized exchange is different from an existing centralized exchange in that the exchange includes transaction prices, buying and selling information, exchange rates for buying and selling, It is not concentrated and managed in one place. Instead, mobile mobile block chain trading devices, realized with smart phones, have limited processing power and storage space and can not accommodate the functionality provided by a single powerful server. Existing member information and passwords should not be located on exchanges, but instead must be present in a mobile block chain trading device of an individual who owns a cryptographic currency or stock.

Preferably, the actuator 228 may comprise a light emitting diode (LED) and / or a speaker. For the transaction confirmation and authentication result, the light output to the LED is continuously operated for a predetermined time, and the speaker generates an alarm sound and notifies the outside. The power supply unit 429 can use a secondary battery such as lithium ion, for example, but can be replaced with various power supply means through other solar panels or wireless charging. In particular, the memory vault 426 can be configured to associate a pattern of registered biometric information with a block-chained password call such as bit coin, etherium, and / or a non-block- Information that is required for currency exchange, such as a secret key or a digital signature, but which requires absolute security, is separately stored and managed in the safe memory, not in the existing memory 424. [ The vault memory stores and manages the digital information or files, including the secret key or digital signature required for the cryptographic currency, transaction history, recent transaction ledger, etc., into the concept of a wallet (or digital wallet). When the information between the safe memory and the processor is encrypted, the encrypted information is decrypted and the decryption information is encrypted.

The display 230 provides a function of recognizing biometric information or receiving specific information, and exists in a form capable of outputting information. The input / output interface 225 provides an RF unit and a baseband unit that enable data transmission and reception through a processor and a wireless communication unit, and an interface and a bus function for mutual input and output of data between the sensor, the display, and the actuator. In order to prevent theft and loss of the external device connected to the device, the wireless RF part and the baseband part may be used to configure and connect a mutual network with the portable smart phone or to prevent theft or loss of the external device. (Wi-Fi), Bluetooth (Bluetooth), etc. in order to request confirmation of the connection with the inventive proposal device at the time of occurrence.

In a preferred embodiment of the present invention, the wireless module incorporated in the trading device enables mutual monitoring for prevention of loss by interlocking with a notebook and a smart phone possessed by the trading device owner, and outputs the data to be transmitted from the related device to the trading device And transmits all the information required for all the objects to be processed using the trading device, and the information can be displayed on the recognition and output module.

In some preferred embodiments of the present invention, instead of the built-in rechargeable battery, a thin film solar cell is built in the outside of the apparatus to enable power supply required by itself.

A block chain trading apparatus according to a preferred embodiment of the present invention is a method of providing information to be sold or bought at a specific server to a specific central server so that a cryptograph holder having a block chain trading apparatus can deal with transactions Related information should be stored and managed within the block chain trading device with existing information.

Since information necessary for transaction is not available in the block chain trading device, it is necessary to collect the information as a solution. The method of collecting does not collect information existing in an existing specific server but shows a configuration for a packet called a pilot shown in FIG. 4. Each block-chain trading apparatus periodically or periodically transmits a pilot packet If necessary and necessary, the packet is selected and transmitted to an arbitrary number of block-chain trading devices among the block-chain trading devices connected to the surrounding block. When the selected block chain trading apparatus receives the pilot packet, the selected block chain trading apparatus selects and transmits a block-chain trading apparatus against an arbitrary number of adjacent block chain trading apparatuses in the same manner. A block chain trading device acting as an intermediary can transmit its pilot packet in a similar manner. When a predetermined time elapses, all the block chain trading apparatuses share the corresponding pilot packet, which provides the same effect as reading information located in a specific server by accessing and reading by all the block chain trading apparatuses.

In the preferred embodiment of the present invention, the pilot packet shown in FIG. 4 includes information 563 including intention to buy or sell, own public key 561 provided by a user wishing to buy or sell, A sequence number and a time stamp 562 are added to the information and the information can be used as information for storing and managing information in the order in which the information is transmitted. In addition, a buy or sell order amount (565) is provided along with a buy or sell order quantity (565). The effective transaction time field 566 is used for automatically discarding long-ago requested information in order to provide only the information for the current-time transaction with the lifetime of the pilot packet to be transmitted and collected.

FIG. 5 shows a space-time diagram illustrating a process according to transmission and reception of a pilot packet according to a preferred embodiment of the present invention. The block chain trading device owned by trader B 150 is represented by an agent program stored and executed in the form of an application program. Periodically, or when the owner of the device wishes to buy or sell, the buy or sell order details are transmitted in the form of pilot packets. The transmission method randomly selects and transmits the neighboring devices to which the device is connected. When a block chain trading device of trader A 110 and trader B 170 receives a pilot packet from a trading device of trader A, the device first checks whether each field constituting the packet has an error or not, If the packet is not satisfied after the verification, the packet is immediately discarded (111). If it passes the verification process, it classifies the similarity of the data by classifying it with the data that passed the reception and verification process earlier, and executes the classification operation to facilitate searching and matching of data suitable for buying or selling.

FIG. 6 is a diagram showing a detailed structure of a packet required for an agent of the device to issue a buy or sell order when an owner having a block-chain trading device attempts to offer a buy or sell order. Replaces the public key of the trading device owner issuing the sell or buy order with the field of public key 512 of the sender and replaces the public key of the trading device owner who has previously bought or sold with the public key 511 of the recipient. At the time when the offer is made, the time stamp value of the trading apparatus is input to the time stamp 513 field. The buy or sell, buy or sell price and quantity are digitally signed (514) with the secret key owned by the originating trading device and loaded into the corresponding field. An executable program to assist in the escrow service of a third party, notarization for proof of transaction, or arbitration of disputes arising from a transaction, rather than simply buying or selling directly between peer-to-peer Code 515 field.

A field indicating the reliability 516 is additionally required when providing a pilot packet including a false order offer packet or false transaction request information according to a preferred embodiment of the present invention. When transactions based on the provision of normal trading information and order information are processed normally, the reliability value of the trading device is increased with respect to the remitter and the payer, and the reliability value is decreased when the trading device is reliable.

According to a preferred embodiment of the present invention, when the reliability satisfies a certain level or more, the transaction processing and exchange proceeds. Otherwise, the transaction processing and exchange are refused.

7, when the trader A 110 which has received the pilot packet for the buy or sell for the trader B 150 makes a decision to buy or sell the information, the offer packet shown in FIG. 6 is transmitted to the trader B (150) in a peer-to-peer manner in terms of time and space.

According to a preferred embodiment of the present invention, the trader A 110 transmits the offer packet to the receiving public key after filling the related field to transmit the offer packet for the purchase or sale transaction. Trader B 150 receiving the offer packet confirms and verifies the accuracy and reliability of the data stored in the field before processing the packet and accepts the offer information in a normal situation. Otherwise, the offer packet is transmitted to the block- .

In some preferred embodiments of the present invention, the accepted offer information is traded and the result of the transaction is sent directly to trader A 110. [

In some preferred embodiments of the present invention, the accepted and processed transaction results are stored and managed in a separate exclusive block of offer information, and the transaction result for the corresponding coded currency is stored in a block chain Transactions and exchanges.

FIG. 8 is a flow chart illustrating a process in which offer information according to a preferred embodiment of the present invention is transmitted and finally reflected on the evaluation information. If the information of the transactions or exchanges collected by the pilot packet in the block chain trading device is stored and the owner of the block chain trading device desires to buy or sell the information based on the information clustered and classified in the corresponding device (S710) of transmitting offer information after inputting information to enter the offer packet with the receiving public key of the other party.

When the block-chain trading device corresponding to the received public key according to the preferred embodiment of the present invention receives the offer information, the step S720 of checking and verifying the offer information included in the packet immediately before the processing is executed . In a normal situation, the block chain trading device corresponding to the receiving public key performs step S730 of trading offer information based on the confirmed and verified information. When the trading is completed, if the normal processing is performed, the trading result should be registered. The method of storing is to store and manage offer information in a block chain in a peer-to-peer computer rather than storing it in an existing central server (S740 ). (S750) of reflecting the evaluation information on the counterparty in the course of transaction and exchange.

FIG. 9 is a flowchart illustrating a more detailed process of the offer information trading step S730 of FIG. 8 according to a preferred embodiment of the present invention. In the block chain trading apparatus, a program called a trading agent is executed, and the corresponding program is directly selected by the owner of the trading apparatus or performs a step S731 of setting a previously set trading condition (quantity, price, number or sale) (S733) requesting an offer for trading. Actual transactions and exchanges must be registered for the offer in the block chain that actually stores and manages the corresponding cipher money. (S735) of confirming that offer information is registered in the block chain.

In accordance with a preferred embodiment of the present invention, after confirming that the requested offer is accepted and processed normally, from the chain of cryptographic currency blocks used for transactions and exchanges, Storing and managing a separate block chain for an offer to store and manage information on trades and exchanges traded and exchanged in the same manner as existing block chains, S737).

FIG. 10 is a flowchart illustrating a process of managing trading results for exchanges and exchanges according to a preferred embodiment of the present invention. Since it is necessary to provide decentralization transactions, the contents of charts and statistical information should be provided in the same way as the centralized exchange. When the offer information is finally processed, the offer information is managed in a block chain called an offer chain for storage and management. (S910) of confirming the registration result of the offer processing result from the corresponding block chain. The process of reading the related offer and the concluded information from the offer chain (S920) is executed. An example of statistical data is transaction price, transaction volume, fluctuation, processing information that is evaluated by a cryptographic account (public key) possessed by a trading device owner Step S930 is executed. In addition, as a matter of reference for the next trading, a step S940 of separately maintaining and managing information that should be considered for the purpose of pursuing the trade and exchange margin as much as possible is performed.

According to a preferred embodiment of the present invention, separately processing the transmission and the spreading of the pilot packet periodically or event-based separately from the task of preparing and transmitting the offer packet and the statistical data for the post-management.
