The purse interface 110 and the transmission transaction server 230 may be connected through the dedicated network 10. The channel server 100 communicates with the block-chain network 300 and can periodically communicate with the block-chain network at a predetermined time for virtual currency transaction, settlement, settlement, transmission, reception, and the like.

Meanwhile, although not shown, the virtual currency wallet system 1000 may include a front-end processor (FEP). The preprocessing processor is provided on the communication network between the virtual currency transaction intermediary member and the virtual currency exchange, and provides a communication path necessary for data transmission / reception between the transmission transaction server 230 and the wallet interface 110.

The virtual currency wallet 210 is a hierarchical deterministic wallet (Hierarchical Deterministic Wallet), and generates a root seed for generating a virtual currency address associated with a hierarchical deterministic based virtual currency wallet structure . The virtual call wall structure based on hierarchical determinism means a virtual currency wallet that continuously generates a virtual call address based on the concept of a lower layer of a virtual call address generated first. That is, the virtual call addresses generated through the hierarchical determinism-based virtual call wall structure are hierarchically related to the virtual call addresses generated at the beginning. In addition, the root seed (RootSeed) is information for generating the first virtual call address, and may include a random value of 512 bits as an example. Since the virtual currency wallet 210 generates a root seed and generates a virtual call address based on the hierarchical deterministic logic using the root seed, if the root seed is safely backed up, even if the information of the virtual call address is lost, It can be recovered via root seed.

The virtual currency wallet 210 may generate a private key for each virtual currency associated with the virtual call address based on the root seed. The personal identifier may be generated for each type of virtual currency (e.g., bit coin, etherium, ripple, dash coin, etc.). A personal identifier is an important element of a virtual currency transaction, and can be used as a signature when the transaction is reasonable and correct in a virtual currency transaction. That is, transmission / reception of a virtual call, deposit / withdrawal can be performed based on the individual identifier. In addition, the virtual currency wallet 210 may generate a public key pairing with the individual identifier and the individual identifier based on the root seed. Illustratively, the virtual currency wallet 210 may generate a virtual call address by referring to the public identifier when generating the virtual call address.
