S230 is determined in corresponding second fund pool of the first currency of the first quantity in first fund pool
The second-cash of two quantity, second fund pool is in the second environment.
Moneytary operations is carried out between two varying environments, can fund pool be arranged in other side's environment respectively in both sides.To this
Fund pool is transferred accounts, you can thinks that the fund is flowed into the environment of the fund pool pair.From other accounts of the fund pool into environment
It transfers accounts at family, you can think that the fund is flowed into from the corresponding environment of the fund pool in this environment.
For example, in conjunction with the example of above-mentioned first environment and second environment.China Construction Bank can be in someiyoshine bank
Second fund pool is set, the first fund pool is arranged in China Construction Bank in someiyoshine bank, then, in user from China Reconstructs
When the account of bank is transferred accounts to the account of someiyoshine bank, actual flow is to first pass through the account of China Construction Bank
Family is transferred accounts the first currency of the first quantity to the first fund pool, and the first currency for being equivalent to first quantity is flowed into someiyoshine
Bank's (actual funds still in China Construction Bank, but right belongs to someiyoshine bank), then passes through Japanese cherry again
Spend the second-cash of the second fund pool in bank to someiyoshine bank transfer and the first money equivalent value of the first quantity.
In this process, the first currency of the first quantity is needed to determine the second-cash of the second quantity, first quantity
First currency and the second-cash of the second quantity such as are at the values, can specifically be converted according to the current exchange rate, that is, according to
The exchange rate of first currency and the second-cash determines corresponding second fund of the first currency of the first quantity in the first fund pool
The second-cash of second quantity in pond.
S240 uses the second quantity described in second fund pool in the second environment by the second block chain
The second-cash be traded with the commodity.
Wherein, first environment and second environment can be traded using different block chains, the first block chain and
Two block chains can be associated.When the first currency is issued based on the first block chain, the second-cash is sent out based on the second-cash
When row, the trade fair transferred accounts to the first fund pool in the first block chain is sent to the second block chain and synchronizes processing, phase
It is same to carry out that the transaction request transferred accounts to the second fund pool in the second block chain answered can also be sent to the first block chain
Step processing.
First environment and second environment can also be traded using the same block chain.For common form (non-block
Chain form) distribution currency, first environment and second environment can will be recorded in block in the relevant transfer information of fund pool
In chain.
In addition, can also receive transaction request in second environment, the embodiment of the present invention can also include the following steps at this time：
