Description

Blockchain-based Kerricoin Transaction Management Platform {Kerricoin Blockchain Managing Platform}

The present invention relates to a Kericoin transaction management platform, and more particularly, to a blockchain-based Kericoin transaction management platform in which a game user uses Kericoin received as a reward in an augmented reality game as payment currency in an affiliate shop.

Augmented reality refers to a technology that superimposes a virtual object on the real world that a user sees with their eyes. It is also called mixed reality because the virtual world with additional information in real time is combined with the real world and displayed as a single image. In addition, an augmented reality game is a game that uses augmented reality technology to encounter virtual items and objects in the real world, which is a real environment, at a location designated by the game platform, and manipulates the touch to process the event. In this way, the user moves around the real world and generates event processing to play the augmented reality game.

And looking at mobile communication technology, the current mobile communication technology is evolving into the 5G generation that provides various communication services using faster data communication and multimedia.

In addition, in the communication terminal, which is a mobile device using this communication technology, as a result of technological innovation in each field of processor such as CPU, memory such as RAM and ROM, various peripheral devices, and implementation technology, both multi-functionality and high-functionalization have been developed rapidly. there is. As described above, with the tremendous technological advancements related to mobile communication and communication terminals, various communication services such as video calls, e-mails, web browsing, chatting, etc. as well as voice calls are being realized in smart phones. In addition, the multifunctional communication terminal is equipped with various devices such as LCD / OLED display module, camera module, contactless IC card module, infrared communication module, Bluetooth communication module, Wi-Fi communication module, GPS module, acceleration sensor, geomagnetic sensor, and sensor module. there is.

In addition, the multifunctionalization of communication terminals is continuously developing in the software installed, and various application software to control various modules are also used for various viewers, multimedia players, browsers, mail, games, personal information management (PIM), etc. The application software is implemented in the terminal operating system, and it is possible to realize high-level functions by executing multiple application programs in parallel with the multi-tasking function.

Meanwhile, in the field of information processing, research is being conducted on virtual reality, which composes a virtual reality space by computer graphics, and augmented reality, which adds more information by processing images in real space with a computer. Augmented reality technology is attracting attention. Several aspects can be considered in the realization method of augmented reality using this augmented reality technology, and it can be seen that a terminal equipped with a camera phone is used in one of them.

In location information-based augmented reality games linked to location information services, virtual buildings or characters often appear, so it is equipped with an augmented reality display function that synthesizes and displays buildings or characters in the landscape of the user's current location for game production. .

However, the existing augmented reality game simply handles events while moving virtual items and objects that have appeared by touch operation. The reality is that this virtual currency cannot be used as a payment method to provide benefits that users can purchase at stores and nearby stores, that is, they provide economic rewards while enjoying the game.

On the other hand, blockchain is composed of four basic technologies, which are P2P (Peer-to-Peer) network, encryption, distributed ledger, and distributed consensus. They are complementary to each other and form the basis of the blockchain operating mechanism. And, smart contract, an application technology in the blockchain environment, is attracting attention in the fields of automated transaction and control as a technology that provides integrity and reliability of the execution code of the program and the result. First of all, the connection and communication between participants in the blockchain is based on a P2P network. A P2P network is a network composed of participants of the same layer that breaks away from the existing client-server method, and is largely classified into structured P2P (structured P2P) and unstructured P2P (unstructured P2P).

In particular, unstructured P2P can be subdivided into a centralized method in which a network between participants is centered on a server and a distributed P2P network based on a data flooding algorithm. Blockchain uses an unstructured P2P network based on flooding for a decentralized distributed network that is a characteristic and ideology of the technology.

In addition, although P2P network communication is generally performed through UDP (user datagram protocol), TCP/IP is used in block chains.

Therefore, participants in the blockchain maintain the IP of the participants who are physically closest to them and use it to send and receive messages and data.

The encryption technology used in the block chain uses a merkle state tree for data integrity validation and a public key-based digital signature technique for non-repudiation of transactions. A Merkle tree is a kind of hash tree, and refers to a tree in which the names of all non-leaf nodes are composed of hashes of child nodes. That is, leaf nodes point to data such as a file or a specific value, and an upper layer node is composed of a hash of this leaf node. The root node of the Merkle tree constructed in this way consists of hash values of the data of all leaf nodes constituting the tree, and the user can verify the forgery of data only by verifying the hash of the root node. there is. Therefore, in the blockchain, transactions and information between participants are inserted in the leaf node to form the basis of the Merkle tree. There are several hash functions that can be used to create the upper node, but in the blockchain, SHA-256 (secure hash algorithm-256) ) function to utilize the Merkle tree.

A public key-based digital signature method is an encryption technology that enables secure communication between participants who do not share a private key in advance, and is widely used in fields such as identity authentication. In a public key infrastructure, two key pairs exist: a public key and a private key. The public key is known to all participants, but the corresponding private key must be maintained so that only the owner can know it. This public key-based digital signature method is used to validate the transaction in the blockchain. A user who wants to generate a transaction uses his/her private key to sign the transaction and transmits the transaction information to the blockchain network along with his/her public key corresponding to it. All other participants who receive this transaction information use the sender's public key in the transaction to validate the transaction, thereby confirming that the transaction was sent by a participant in the blockchain.

A distributed ledger is a record repository of information that is replicated, shared, and synchronized by consensus among participants. In particular, in order for the distributed ledger to be applied on the P2P network, it has the characteristic that participants need to agree on the records of the distributed ledger, and this feature is maintained in the blockchain as well. In the blockchain, the distributed ledger records all transactions and information that occur through the verification process of the participants, and all participants maintain the same information.

When verifying transactions or information, first, the connection with the information already recorded in the distributed ledger maintained by each participant is checked, and only legitimate transactions or information are stored in the distributed ledger of the block chain through consensus among the participants. When storing transactions or information, they are accumulated for a certain period of time and stored in a unit called a block and stored in a distributed ledger with connectivity between these blocks. This distributed ledger is the basis for data integrity protection provided by blockchain. Since all users participating in the blockchain maintain the same distributed ledger data, in order for an attacker to forge or forge specific data from the outside or attempt a double transaction, it is necessary to access more than half of the distributed ledgers maintained by the participants. Because the attack must be attempted, it requires high cost and computing resources.

Distributed consensus is a protocol that derives agreement on specific data values between processes or agents in order to achieve overall system reliability when there is a defective process in the fields of distributed computing and multi-agent systems. The distributed consensus protocol for this has the following properties. First, validity, i.e. if all correct processes have proposed the same data, all processes make a decision (valid, invalid) on the proposed data, secondly, integrity i.e. all correct processes accept one data If so, the data is data proposed by another process. Third, agreement, all correct processes must agree on some data, and fourth, termination, all correct processes must agree on some data. have to make decisions about them.

In the block chain, the distributed consensus protocol is designed as above, and consensus among the participants is drawn on the transactions or information that occur through it. It is one of the key parts because only suitable transactions or information are maintained in the blockchain through consensus. Also, depending on what kind of distributed consensus protocol is used, the characteristics of the block chain are distinguished and the reliability of the system is also affected. In the case of Bitcoin, which can be said to be a representative blockchain service, a distributed consensus protocol called proof-of-work is used. This proof-of-work protocol is a protocol that draws consensus on block information among participants by performing the task of finding a specific hash value by trial and error using the transaction and data to be stored as a block and the SHA-256 hash function. At this time, the blockchain can use a voting-based consensus algorithm called proof-of stake, and although the security is lower than the proof-of-work consensus, it can solve the problems of consensus speed and power consumption. Consensus algorithms such as Delegated Proof-of-Stake (DPoS) and Practical Byzantine Fault Tolerance (PBFT)-based tendermint based on such proof-of-stake may be further used.

Hereinafter, the advantages and features of the present invention, and a method of achieving them, will become apparent with reference to the embodiments described below in detail in conjunction with the accompanying drawings. However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various different forms, and is provided to completely inform those of ordinary skill in the art to the scope of the invention As such, the invention is only defined by the scope of the claims. In addition, in the description of the present invention, when it is determined that related known techniques may obscure the gist of the present invention, a detailed description thereof will be omitted.

Hereinafter, the present invention will be described in more detail with reference to the drawings.

1 is a diagram for explaining a general block chain structure.

Referring to FIG. 1, a block of a block chain consists of a header and a body. The header contains information for creating a linked list in a single block, and the body contains the contents of the transaction contained in the block. In the case of Kericoin, a virtual currency, the header may include information such as software version, difficulty, hash value of the previous block, block creation time, merkroot, and nonce, and the body includes at least one transaction can do.

To create a block, it is necessary to find the nonce value, and the hash value of the previous block is used to calculate the nonce value of the new block. This process of finding the value of nonce is expressed as mining in Bitcoin, a virtual currency, and is also called a 'consensus algorithm'. This enables a distributed ledger function that allows participants to hold the same ledger in real time on a blockchain network, linking blocks together. Blockchain stability comes from the extension of chain length through linked lists and the same ledger among blockchain network participants. As the length of the chain gets longer, it becomes almost impossible to hack a single block that already exists. Data manipulation on the blockchain is impossible unless you have

On the other hand, in terms of its utilization, the block chain is in the form of a public block chain, a private block chain, and a consortium block chain. In the case of a public blockchain, anyone can participate and anyone can view information. The private blockchain can apply limited functions depending on the purpose, such as limiting the number of participants and the scope of viewing. And, the consortium blockchain is an intermediate form between public and private blockchains, and is configured to interoperate between public and private blockchains.

Hyperledger is a worldwide open-source collaborative activity organized to advance blockchain technology across industries, led by the Linux Foundation. A total of 130+ members in finance, banking, Internet of Things, supply chain, manufacturing and technology are currently participating in eight projects including Hyperledger Fabric and Hyperledger Composer, developing a standardized open, enterprise-grade distributed ledger framework and code base. are working for

Referring to FIG. 2 , the block structure of the hyperledger fabric protects past transaction information from being damaged by storing the block structure using an encrypted hash function. In addition, the block structure of Hyperledger Fabric is almost the same as that of Bitcoin, but it is characterized in that a key-value store (KVS) hash value is also recorded.

The hash value of the previous block is calculated using SHA3 SHAKE256 at 512 bits (64 bytes), and the metadata of the block can be entered freely in each node and is excluded from the hash calculation.

In the present invention, the Hyperledger Fabric block chain system is basically applied to the payment of product price or compensation using Carricoin, and related data or information is stored in a transaction and transmitted/received. However, the present invention is not necessarily limited and applied only to the Hyperledger Fabric block chain system, and can be applied to all block chain systems that can be paid with virtual currency (cryptocurrency) as well as general public block chain systems.

As shown in Fig. 10, first, the wallet generating unit 34a of the Carricoin management server 40 creates a plurality of inactive wallets in advance (step S1). Specifically, the wallet generation unit 34a allocates a unique wallet ID, access code, wallet address, and secret key to one wallet and registers these information in the wallet table of the wallet database 50 . In the inactive wallet, the e-mail address item is not registered in the wallet table, and the Carricoin management server 40 creates a plurality of wallets in which the owner is unconfirmed in advance.

Information pertaining to the inactive wallet is written on the printed card 55 .

That is, each of the cards 55a, 55b, ..55n is printed with the wallet ID, access code, wallet address, and secret key assigned by the wallet generating unit 34a. The access code, wallet address and secret key are scratch-printed and hidden from anyone other than the user who purchased them.

The user who has purchased or acquired the card 55 uses the customer terminal device 10 to access the website to activate the wallet (S2). Since the access information (URL) for the website is written on the card 55, the user (card purchaser) only needs to confirm it. When the customer terminal device 10 accesses the web site, a requirement input form 61 is provided for the customer terminal device 10 from the carrycoin management server 4 . Next, the user (card purchaser) follows the guidance of the input form 61 displayed on the display unit 64 of the customer terminal device 10 , the customer's own e-mail address, and the wallet ID and access code written on the card 55 . is input in the customer terminal device 10 (step S3). The customer terminal device 10 transmits the email address, wallet ID, and access code input by the user (customer) to the carrycoin management server 40 .

When the activation unit 34a of the carrycoin management server 40 receives the information from the customer terminal device 10, it performs an access code authentication process (step S4).

That is, the activation unit 34a checks whether the correspondence between the wallet ID and the access code received from the customer terminal device 10 matches that registered in the wallet table of the wallet database 50 .

When the authentication of the access code is completed, the activation unit 34a transmits an e-mail including a uniform resource locator (URL) of a web page for e-mail authentication to the e-mail address received from the customer terminal device 10 (step S5). The user checks the mail from the carrycoin management server 40 in the customer terminal device 10 and accesses the URL written therein (step S6). When access to the designated URL is confirmed, the activation unit 34a determines that the email address that sent the email is genuine, and registers the email address in the wallet database 50 (step S7).

That is, the wallet ID and e-mail address that the user (customer) has applied for is registered in the wallet table of the wallet database 50 . The wallet for that wallet ID then belongs to the user (customer) who owns that email address. After that, the activation unit 34a activates the wallet associated with the email address (step S8). In this way, users will be able to freely use their wallets and will be able to deposit Carricoins into the wallet or transfer Carricoins from their wallets. Next, when the wallet activation process is completed, the transaction unit 34c of the Carrycoin management server 40 deposits a predetermined amount of Carrycoin corresponding to the sales amount (KRW) into the user's wallet (step S9).

The transaction unit 34c updates the balance value in the balance table of the wallet database 50 when a deposit is processed with a predetermined wallet, and registers the date of the deposit, the transferee, the deposit amount, and the like in the transaction table. Next, similarly to the case of withdrawing Carricoin from the wallet, the transaction unit 34c updates the balance value in the balance table and registers the withdrawal date, remittance destination, withdrawal amount, etc. in the transaction table. In addition, when withdrawing Carricoin, the transaction unit 34c requests the user (customer) to input the wallet ID or wallet address of the remittance destination into the customer terminal device 10 . In addition, in order to perform remittance processing authentication, the transaction unit 34c requests input of the wallet ID and secret key of the remittance destination, and checks whether the correspondence between the input wallet ID and secret key matches that registered in the wallet table. . As described above, when using the card 55, the user (customer) can activate the wallet by simply registering his or her e-mail address to easily start using Carricoin.
