Abstract: A virtual currency storage and transaction system includes a first terminal and a second terminal. The first terminal is in a state of network disconnection, for generating a private key for encrypting a virtual currency wallet according to a seed password and a customized password and generating a storage address with an identification code corresponding to the private key, so as to receive the virtual currency paid to the storage address; also for paying the virtual currency to a third party corresponding to the payment address according to the input payment address. The second terminal is in a state of network connection, for issuing transaction information for payment of the virtual currency to the third party. The first and second terminals mutually scan the identification code on the display interface for information interaction.
