Transaction system and method of digital cryptocurrency with blockchain between parties

The present invention provides a guide to easily perform transactions based on a URL without recognizing a public address consisting of more than 32 bytes for each transaction of a digital cryptocurrency having a blockchain between the parties, thereby making a separate bitcoin payment. It is possible to trade without having a QR code, so every bitcoin transaction between the two parties, which is a detriment of the Bitcoin payment QR code that accompanies the digital virtual currency transaction with blockchain, provides QR codes for all other parties' payments in advance. In addition to the inconvenience, the process is complicated because the transaction must be performed while filming a digital cryptocurrency transaction with a blockchain.In addition, the QR code for payment of the Bitcoin of the donors previously provided by the donor is leaked. Parties that prevent the risk of theft in advance The present invention relates to a trading system and method of digital cryptocurrency having an inter-blockchain.

In general, in the case of a virtual currency that is commercially available, the online game goods proxy purchasing device and method using the virtual currency for PC room managers disclosed in the Korean Patent Office (Public Patent No. 10-2012-0028519), based on the Internet There was a problem in using it because it can only be used to purchase items in online games.

By the way, it has been in the spotlight recently, Bitcoin is a kind of virtual currency that can be paid for in kind.

Bitcoin is a digital currency created by Satoshi Nakamoto in 2009, and has no structure for issuing and managing currency. Instead, Bitcoin's transactions are made through a distributed database based on peer-to-peer networks (P2P), and transactions are carried out based on public key cryptography.

As such, Bitcoin having a payment method can be used without information such as a card number, expiration date and CCV number required for a credit card payment, so that the risk of theft is extremely low as well as a low usage fee.

In addition, Bitcoin is stored in the form of a wallet file, and the wallet is given a private key corresponding to each unique address, that is, a public address and a password, and the public address. The purchase of goods using Bitcoin is made based on the address.

As such, digital cryptocurrency that can be paid in kind includes bitcoin, litcoin, darkcoin, namecoin, pottery coin, and ripple. Since the block chain that collects and keeps the transaction details that have been traded using is stored in the electronic wallet, digital cryptocurrency that has a blockchain collectively known as Bitcoin, Litecoin, Darkcoin, Namecoin, Ceramic Coin and Ripple It is referred to as.

In order to use a digital cryptocurrency with a blockchain with payment characteristics, the user first subscribes to a bitcoin exchange (eg, www.coinplug) and charges KRW corresponding to the won while opening an electronic wallet. .

Then, after checking the current price of Bitcoin being traded on the Bitcoin Exchange, and entering the quantity and unit price of the digital cryptocurrency with the blockchain to be purchased, the transaction is established through the sales order that meets the trading conditions. In this case, the user can make a payment through digital virtual currency with a blockchain.

However, due to the transaction characteristics of the digital cryptocurrency having such a blockchain, there is a problem that cannot provide transactions between users, which is a basic function of general currency currently used in each country including Korea.

In other words, a conventional digital cryptocurrency based trading system with a blockchain is a person who wants to trade a digital cryptocurrency with a blockchain between both parties, that is, a person who gives a digital cryptocurrency with a blockchain (hereinafter referred to as a donor). For digital cryptocurrency transactions with blockchains between recipients of digital cryptocurrencies with blockchain (hereinafter referred to as “verifiers”), the donor first inputs the public address used as a means of identifying digital cryptocurrency transactions with blockchain. In addition, the public address of the recipient must be provided.

However, the public address is 32 bytes to 35 bytes of data composed of a combination of numbers, lowercase letters and uppercase letters, such as "1BBe23rvzYBwaAqckvj4TTTJAs3W78dUpx".

As a result, the presenter often does not know the public address of the recipient rather than the public address of the recipient.

For this reason, when trading goods using digital cryptocurrencies with blockchain, payment is performed using a Bitcoin payment QR code that converts a public address into a QR code, but when it is applied to a transaction between both parties, the blockchain In addition to the inconvenience of having to receive the QR code for Bitcoin payment of all the counterparties who want to give digital cryptocurrency in advance in advance, the transaction must be carried out while filming this when trading digital cryptocurrency with blockchain. In addition to this complexity, the QR code for the donor's Bitcoin payment provided in advance by the donor also causes a risk of theft when an external leak occurs.

The present invention is to solve the problems of the prior art, an object of the present invention is to easily be based on the URL without knowing the public address consisting of more than 32 bytes (byte) for each transaction of the digital cryptocurrency having a blockchain between the parties It is to provide a trading system and method of digital cryptocurrency with a blockchain between the parties to guide the transaction can be performed.
