In this embodiment, the digital currency or the combination of the digital currencies, of which the available amount is greater than or equal to the payment amount, is selected, and the transaction time when the digital currency is used for participating in the transaction can be further calculated, so that whether the digital currency is used for participating in the transaction can be determined, and the transaction efficiency can be improved.
S104, calculating the transaction time of each digital currency or digital currency combination meeting the condition that the available amount is greater than or equal to the payment amount, wherein the transaction time comprises the following steps: the sum of the time spent transmitting the digital currency combination, the time spent signing the digital currency combination, and the time spent verifying the signature of the digital currency combination by the peer device.
The following briefly describes how the hardware wallet selects digital currency or a combination of digital currencies in the case of different payment amounts, where the hardware wallet has digital currencies with amounts of 1, 2, 5, 7, 10, 13, and 15, and the selection process of the hardware wallet digital currencies in the above embodiments is taken as an example.
(1) The payment amount is 13;
the obtained payment amount is 13, and all digital currencies meeting the payment amount condition are as follows: 13. 15; the digital currency combination is as follows: {1, 2, 5, 7}, {2, 5, 7, 10}, … … {1, 15 }. After all the digital currency or the digital currency combination meeting the available amount and larger than or equal to the payment condition are obtained, the transaction time of each digital currency or digital currency combination meeting the condition is further calculated, and then the currency to be output is determined according to the transaction time and is output.
(2) The payment amount is 100
The obtained payment amount is 100, and the digital currency or the digital currency combination with the available amount larger than or equal to the payment amount does not exist in all the internally stored digital currencies, so that the transaction can be further selected to be ended.
And S105, determining the digital currency or the digital currency combination with the transaction time meeting the preset conditions as the currency to be output.
In an optional implementation manner of this embodiment, determining that the transaction time meets the preset condition includes: and comparing the transaction time with a threshold time calculated according to the basic information parameters, determining that the transaction time meets a preset condition under the condition that the transaction time is less than the threshold time, and taking the digital currency or the digital currency combination meeting the preset condition as the currency to be output. In the optional embodiment, the transaction time is compared with the threshold time to obtain the digital currency or the digital currency combination meeting the preset condition, so that the digital currency or the digital currency combination with overlong transaction time is prevented from participating in the transaction, and the transaction efficiency is improved.
In an optional implementation manner of this embodiment, determining that the digital currency or the combination of digital currencies whose transaction time meets the preset condition is the currency to be output includes: and determining the digital currency or the combination of the digital currencies which have the shortest transaction time, the minimum payment data chain and the closest available amount to the payment amount to be output as the currency to be output. In this optional embodiment, in order to increase the data transmission speed of the off-line transaction, when the digital money is transmitted, the digital money with small data volume is preferably used for the transaction, so the hardware wallet uses as little digital money as possible to participate in the transaction, preferably uses no payment data chain and uses less digital money to participate in the transaction, and improves the transaction efficiency.
And S106, outputting the money to be output.
By the method for selecting the digital currency of the hardware wallet provided by the embodiment, after the digital currency or the combination of the digital currencies stored in the hardware wallet is judged to have the digital currency or the combination of the digital currencies larger than or equal to the payment amount, the transaction time is calculated, and the digital currency or the combination of the digital currencies with the transaction time meeting the preset conditions is determined to be the currency to be output and output.
