Description
Technical Field
the invention relates to the technical field of computers, in particular to a digital currency active storage method and device based on a block chain.
Background
the currency plays a vital role in the life of people, and people can not leave the currency in clothes, eating and housing. The current deposit is symmetrical to the 'regular deposit', and the deposit period is not specified, and the deposit can be accessed at any time. According to the current regulation of China: when the account is opened by the current saving, the account is saved for 1 yuan, and the more accounts are not limited; the bank sends the current deposit passbook to the depositor to access according to the passbook; the settlement is carried out once every year, the principal interest (the number of the tails below the Yuan is not counted as interest) is added, and the interest is calculated until the day before the settlement of the account for the people who are not in the settlement period. The live saving is characterized in that: flexible, convenient, more households, wide range, sporadic amount, frequent receipt and payment and large liquidity of funds. The living reserve money of people, and mutual saving of units and residents are suitable for saving in the mode. Due to the fact that the live savings have no fixed life period, the live savings are not well arranged when the live savings are used as fixed fund sources. Therefore, demand savings are lower than demand savings.

wherein, the user can send the data of the current storage to the block chain through the terminal. For example, the terminal may provide a blockchain wallet through which the user may initiate a live storage operation, and through an interactive interface provided by the blockchain wallet, may obtain the user's account principal, i.e., the amount of principal obtained and the account providing the principal. The total savings account may be an address of a savings operator, for example, the total savings operator is the digital money issuer. The savings start time may be the time at which the principal was successfully transferred to the total savings account.
In some embodiments, the current savings data is intelligent contract data, and the following steps S220-S250 may be performed according to the specification of the intelligent contract.
S220, transferring the first amount of digital money from the account of the user to the total saving account through the blockchain.
After determining the current savings data, the current savings data may be recorded in a blockchain to enable transfer of a first amount of digital currency from the user's account to the total savings account through the blockchain. For example, a transaction event may be generated according to the current deposit data, the transaction event being used to instruct to transfer an account of a user with a first amount of digital money to a total deposit account, the transaction event being sent to a block-out node, and the block-out node performs verification, packaging and time stamping, and then performs network-wide synchronization.
s230, in response to the fetch request, determining a fetch time and a third number.
The digital money deposited in the total deposit account may be extracted at any time, and during the extraction, all the digital money corresponding to the user account may be extracted in advance, or a part of the digital money corresponding to the user account may be extracted. The method is determined according to actual needs. The withdrawal request may correspond to a third amount of digital currency to be withdrawn, which may be equal to the first amount or less than the first amount.
And S240, calculating interest according to the third quantity and the extraction time. The interest is a second amount of digital currency.
And S250, transferring the third amount and the second amount of digital money from the total deposit account to the account of the user through the block chain. The third number is not greater than the first number.
The transaction event can be generated according to the third amount of digital money and the second amount of digital money, the total deposit account and the account of the user, the transaction event is sent to the block-out node, and the block-out node carries out verification, packaging and time stamping and then carries out whole network synchronization.
the step S250 may include various implementations, and is described below with reference to specific examples.
as one example, a user's account may include an interest account and a principal account; the S250 may specifically include: transferring a third amount of digital money from the total savings account to the principal account and a second amount of digital money from the total savings account to the interest account via the blockchain.
as another example, the total savings account includes a total principal account and a total interest account; the S250 may specifically include: transferring a third amount of digital currency from the principal account to the user's account and a second amount of digital currency from the principal account to the user's account via the blockchain.
As another example, the user's account may include an interest account and a principal account; the total savings account comprises a total principal account and a total interest account; the S250 may specifically include: transferring a third amount of digital currency from the general principal account to the principal account and a second amount of digital currency from the general interest account to the interest account via the blockchain.
In some embodiments, the settlement of interest may include a plurality of ways, which may be determined according to actual needs, for example, interest may be calculated daily, weekly or yearly, and of course, other settlement ways may be adopted in specific implementation. As another example, the interest may be in the same or different digital currency as the principal.
as an example, the method may further comprise: and responding to the interest extraction request, converting the second amount of digital currency into a fourth amount of stable currency and extracting according to the corresponding relation between the digital currency corresponding to the interest and the stable currency.
for the extraction of the stability ratio, the transfer-out address, the transfer-in address and the transaction quantity can be determined, a transaction event is generated and sent to the block-out node, and the block-out node performs verification, packaging and whole network broadcasting after being stamped.
As another example, for periodic settlement interest, the following steps are specifically performed:
step 1), in response to the interest settlement command, determining the interest in the current period according to the interest settlement period and the third amount;
And 2), transferring the interest of the current period from the total deposit account to the account of the user through the block chain.
As another example, for the way of periodically settling interest, when extracting, there is a part of interest that has not been settled in the period, and the settlement can be performed by performing the following steps:
Step a), determining the time of non-interest settlement according to the extraction time and the interest settlement period;
And b), determining interest according to the first amount and the time of the unconsolidated interest.
The embodiment of the invention realizes the live storage of the digital currency through the block chain, has convenient operation and higher efficiency, and can ensure certain credibility and safety. In the process of obtaining deposit, interest calculation can be carried out more flexibly and conveniently, so that the whole data processing process is more flexible, and the user experience is better.
