Preferably, the virtual coin operation request comprises a virtual coin receiving request, a virtual coin expenditure request and a virtual coin operation detail query request. Through the design, the user can realize various basic operations on the virtual coin portable operation terminal, and the convenience of use is improved.
Preferably, the virtual coin receiving request sending comprises the following steps:
and the distributed account book running program generates a local virtual currency account address and sends the local virtual currency account address to the block chain server.
And the block chain server receives the local virtual coin account address and sends the local virtual coin account address to a virtual coin sending terminal.
And after receiving the local virtual coin account address, the virtual coin sending terminal sends the virtual coin to the local machine according to the local virtual coin account address.
Through the steps, the virtual coin can be received, and the address of the opposite virtual coin is required to be known for both the transmission and the reception of the virtual coin in the block chain, so that the account address of the opposite virtual coin is determined in advance no matter the virtual coin is transmitted or received.
When a user needs to receive the virtual coin, the distributed account book running program on the portable virtual coin operation terminal firstly sends the account address of the local virtual coin to the virtual coin sending terminal through the block chain server, namely a node of the block chain, and the virtual coin sending terminal sends the virtual coin to the address, so that the portable virtual coin operation terminal can complete the virtual coin receiving.
Preferably, the virtual coin payout request sending comprises the following steps:
the distributed ledger execution program receives the virtual currency receiver address sent by the blockchain server.
And the distributed account book running program sends the virtual coin to a virtual coin receiver according to the address of the virtual coin receiver.
Through the steps, the virtual coin can be sent, the virtual coin sending and the virtual coin receiving work process are opposite, when the virtual coin is sent, the address of the virtual coin receiving party is required to be received by the portable operating terminal of the virtual coin from the block chain server, and the virtual coin can be sent only after the address of the virtual coin receiving party is known.
Optimally, the virtual coin expenditure request can be further realized by the following steps:
and scanning an external virtual coin address two-dimensional code, and transmitting the two-dimensional code to the distributed account book running program for identification.
And the distributed account book running program identifies the virtual coin address two-dimensional code to obtain a virtual coin address in the virtual coin address two-dimensional code.
