Description

BLOCK CHAIN SYSTEM ARCHITECTURE AND METHOD}

The present invention relates to a structure and method of a blockchain system, and more particularly, to a structure and a method of a blockchain system for performing a transaction between user terminals using blockchain technology.

Block chain, also known as public trading ledger, is a technology that prevents 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 to prevent data forgery. Blockchain is applied to Bitcoin, a representative online virtual currency. Bitcoin records transaction details transparently 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 pear to pear (P2P) manner 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. For example, if 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. Can be authenticated.

Recently, as the interest in blockchain security technology increases, blockchain technology has been applied to various fields such as financial transactions, medical data management, and file management as well as virtual currency.

The blockchain method has the advantage of excellent security because all nodes share the same information so that the malicious nodes must modify the contents of the blockchain owned by all nodes in order to modify the contents arbitrarily.

However, since the blockchain method shares all the data in the user terminal, when the 50% or more users collide to perform the operation, there may be a problem of recognizing the manipulated data in all the user terminals.

DETAILED DESCRIPTION Hereinafter, exemplary embodiments of the present invention will be described with reference to the accompanying drawings. These embodiments are described in sufficient detail to enable those skilled in the art to practice the invention. It is to be understood that the various embodiments of the invention are different, but need not be mutually exclusive. For example, certain shapes, structures, and characteristics described herein may be embodied in other embodiments without departing from the spirit and scope of the invention with respect to one embodiment. In addition, it is to be understood that the location or arrangement of individual components within each disclosed embodiment may be changed without departing from the spirit and scope of the invention. Accordingly, the following detailed description is not to be taken in a limiting sense, and the scope of the present invention is defined only by the appended claims, along with the full range of equivalents to which such claims are entitled. Like reference numerals in the drawings refer to the same or similar functions throughout the several aspects.

Unless otherwise defined, all terms (including technical and scientific terms) used in the present specification 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 specifically defined clearly.

The present invention does not form a blockchain between user terminals, but the network devices form a block chain as a blockchain controller and efficiently perform energy consumption of the user terminal by performing a task to be performed in the user terminal through the blockchain controller. Disclosed is a blockchain system architecture and method that can be reduced.

In the general blockchain system, since users have all the data, if more than 50% of the users collide and manipulate the data, it becomes a problem because all the users recognize the manipulated data. For example, the conventional blockchain is vulnerable to attack because there is no controller or a central control system, and if it occupies more than half, there is a problem that the entire contents can be modified.

Therefore, in the present invention, a plurality of blockchain controllers form a blockchain network, and the user terminal can secure stronger security by authenticating using the blockchain controller. In the present invention, rather than forming a block chain between user terminals as in the prior art, the network equipment is configured as a block chain, which will be referred to as a block chain controller.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily implement the present invention.

1 is a diagram illustrating the concept of a blockchain method to which the present invention is applied. Referring to FIG. 1, a block chain is a linked list that contains a link to the previous block starting with the first block. Blockchains are distributed and stored and managed across multiple nodes 100, 110, 120, and 130, and each block contains transaction information (transactions), so a blockchain that is a collection of blocks contains a huge amount of all transaction information. It can be called a distributed ledger. In other words, a block is an element of a blockchain and conceptually means a bundle of a plurality of transaction information (transactions). A block consists of block headers, transaction information, and other information.

1 is a block diagram illustrating nodes between block chains according to an embodiment of the present invention. As described above, the blockchain uses a distributed technology, and information about each user terminal is stored in a plurality of blockchain controllers (eg, nodes 0 to 3 in FIG. 1) using a peer to peer (P2P) technology. do. Since these nodes share blocks in a chained state, many of the nodes must be hacked to forge data connected in the blockchain. In addition, if the transaction is accumulated more than a certain amount of time, the nodes accumulate the same information stored in the same process through the process of mutual agreement.

For example, if a block corresponds to a predetermined period, node 0 creates the transactions as one block. This block consists of the block header containing the block header and the actual transaction contents. In this block, the block header is used as a parameter and the nodes 1 to 3 are mutually agreed.

In the present invention, a blockchain system can be implemented through a blockchain controller. Here, the node connected to the end user terminal, not the user terminal located at the end, may serve as a block chain controller. One node may simultaneously process transactions of one or more user terminals. The blockchain controller can use a search protocol to search for other blockchain controllers and user terminals in the network. The blockchain controller can grasp the details of the connected user terminal. Transactions occur between user terminals, but for data backup and security, the blockchain controller can store and synchronize transaction-related information with other blockchain controllers.

According to one embodiment, the blockchain controller can be installed and used in existing network equipment and infrastructure. Blockchain controllers not only provide a secure way of communicating or transacting, but they also encourage the use of blockchain by reducing the cost of installing new network devices to implement blockchain systems and reducing the computation / storage burden on user terminals. .
