The present invention relates to a system and method for trading digital virtual money having a blockchain between parties, which guides to facilitate a URL-based simple trade without recognising a public address formed with 32 bytes or more whenever trading digital virtual money having a blockchain between parties, thereby facilitating trade without a QR code for separate bitcoin payments, and preventing a number of disadvantageous effects of the QR code for bitcoin payments involving trade of digital virtual money having a blockchain, together with the inconvenience in which QR codes for bitcoin payments of all parties are required to be provided in advance one by one whenever trading bitcoins between both parties, and not only is the process complex because the trade is required to be performed by photographing the QR code when trading digital virtual money having a blockchain, but also accordingly theft risks when the giver's QR codes for bitcoin payments provided in advance to a receiver are leaked. The system comprising: blockchain retention servers (100) in which a blockchain for authenticating a blockchain-based digital virtual money trade by verifying transaction information for a trade of digital virtual money having the transmitted blockchain when the transaction information for a trade of digital virtual money having a blockchain is transmitted, and for recording the transaction information for a trade of digital virtual money having a blockchain according to the authentication is installed; a blockchain-based digital virtual money trade guide server (200) that generates and transmits a receiver recognition URL (A) for guiding so that a receiver receiving the digital virtual money having a blockchain can be recognised if a trade request signal for a giver is transmitted, to deduct the amount to be given to a receiver from information about the amount of blockchain-based digital virtual money retained in a giver's electronic wallet if a personal profile signal for receiver recognition is transmitted, to generate transaction information for digital virtual money trade that is composed of transactions in which the deducted amount is accumulated in the information about the amount of blockchain-based digital virtual money in the receiver's electronic wallet, and to disseminate the same to the blockchain retention servers (100); a giver's terminal (300) in which a giver's side application is installed for a blockchain-based digital virtual money trade (310) for guiding so that a trade request signal for a giver including information about the amount of digital virtual money having a blockchain to be given and the giver's personal information can be generated, the same can be transmitted to the digital virtual money trade guide server (200), and a receiver to whom the receiver recognition URL (A) transmitted from the digital virtual money trade guide server (200) is to be handed can be assigned and transmitted; and a receiver's terminal (400) in which a receiver's side application for a blockchain-based digital virtual money trade (410) is installed for controlling to automatically execute when clicking the receiver recognition URL (A) transmitted from the giver's terminal (300) so as to generate a personal profile signal for receiver recognition including personal information about the receiver receiving the digital virtual money having a blockchain, and to transmit the same to the digital virtual money trade guide server (200), and the method using the same are provided. |
