The smart contract virtual wallet generator returns the query result to the virtual wallet. Then the virtual wallet executes the transfer operation corresponding to the next transfer sequence number.
本實施例中，由於收款方節點設備與撥款方節點設備在進行轉帳交易時，透過區塊鏈管理節點設備作為中間媒介將轉帳總金額分拆到複數個虛 擬錢包中，並透過複數個虛擬錢包完成向收款方節點設備的轉帳操作，因而無法直觀的確定轉帳交易雙方的帳號位址，從而保護了轉帳交易雙方的隱私安全。 In this embodiment, since the node device of the payee and the node device of the grantor are in the transfer transaction, the block chain management node device is used as an intermediary to split the total amount of transfer into a plurality of virtual funds. In the pseudo-wallet, the transfer operation to the node device of the payee is completed through multiple virtual wallets, so the account addresses of both parties to the transfer transaction cannot be determined intuitively, thereby protecting the privacy of both parties in the transfer transaction.
