Detailed Description
The following description of the embodiments of the present invention will be made apparent and fully in view of the accompanying drawings, in which some, but not all embodiments of the invention are shown. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The technical features of the different embodiments of the invention described below may be combined with one another as long as they do not conflict with one another.
Example 1
The embodiment of the invention provides an account management method based on a blockchain, which is shown in fig. 1 and comprises the following steps:
step S10: and establishing virtual accounts corresponding to the transaction information for the entity accounts of the transaction participants on the blockchain according to the transaction information, wherein the virtual accounts comprise service attributes which are used for representing the purposes of the virtual accounts. In a specific embodiment, as shown in fig. 2, each physical account is divided into a plurality of virtual accounts, different virtual accounts are respectively used for different services, all virtual accounts are located in the same blockchain, the virtual accounts are uniformly managed through the blockchain, and the establishment and the revocation of the virtual accounts are realized through the blockchain. The business implementation of the virtual account is set based on the transaction information, for example, the entity account a issues payroll to the entity account B, and then a virtual account with a business attribute of "issue payroll" can be established in the entity account a, and a virtual account with a business attribute of "receive payroll" can be established in the entity account.
Step S20: and completing the transaction according to the virtual account corresponding to the transaction information. It should be noted that the actual operation is an operation on an entity account, and the virtual account may record the fund transaction data of different services.
According to the block chain-based account management method provided by the invention, the virtual account is established for the entity account of the transaction participant according to the transaction information, the virtual account comprises the service attribute for representing the purpose of the virtual account, the transaction is completed through the established virtual account, different virtual accounts are established for the entity account according to different transactions, the transactions generated by different services in the entity account are distinguished, convenience is brought to checking accounts of users, and the maintenance of an account system is simpler.
In an alternative embodiment, as shown in fig. 3, after the step S10, before the step S20, the method further includes:
step S30: forming virtual account consensus according to business rules of the transaction participants, forming intelligent contracts according to the business rules, and recording the intelligent contracts on a blockchain. In a specific embodiment, the business rule is a rule in the transaction information, including a payment mode, a payment time, a payment condition, a payment amount and the like, and the business rule is recorded on the blockchain in a form of a contract only, so that the blockchain can complete automatic control of the virtual account according to the intelligent contract.
In an alternative embodiment, as shown in fig. 4, the step S20 specifically includes:
step S21: and judging whether the triggering condition of the intelligent contract is met, if yes, executing the step S22, and if not, executing no operation.
Step S22: funds transfer between the virtual accounts of the transaction participants is accomplished through the smart contracts. In a specific embodiment, the user may set different trigger conditions according to actual requirements, where the different trigger conditions correspond to different transactions, for example, the trigger condition may be that the virtual account a enters account, and the transaction corresponding to the trigger condition is that the virtual account a rotates ten percent of account entering account to the virtual account b, and then when the virtual account a has funds to enter account, the virtual account a automatically rotates ten percent of account entering account to the virtual account b, so as to realize automatic account splitting of the entity account. By way of example only, various services may also be automatically completed between virtual accounts via smart contracts.
In an alternative embodiment, the transaction participants mentioned in step S10 include: before the step S10, the transaction initiator and the transaction receiver further include:
recording the transaction initiator, the transaction receiver and the transaction information in a first blockchain account book, and after recording the transaction initiator, the transaction receiver and the transaction information in the first blockchain account book, in order to ensure that the transaction initiator has the capability of executing the transaction, the funds required for completing the transaction need to be frozen in the account of the transaction initiator.
In an alternative embodiment, the step S22 specifically includes: when the transaction conditions of the transaction initiator are met, corresponding transaction is triggered, funds transfer between virtual accounts of the transaction initiator and the transaction receiver is completed, and the transaction is recorded in a second blockchain account book.
Taking the transaction flow shown in fig. 5 as an example, after the user a purchases 100 ten thousand products of the value of the user B, transaction information is formed, the transaction information includes a transaction initiator a, a transaction receiver B, and a transaction amount of 100 ten thousand, and may further include transfer triggering conditions, after the transaction information is formed, the transaction information, the transaction initiator a, and the transaction receiver B are recorded in a blockchain codebook at time 2, in order to determine which transaction corresponds to the funds circulation in the accounts of a and B, the blockchain establishes a virtual account in the entity account of the user a, sets an attribute tag "purchase product" for the virtual account, identifies the funds circulation of the virtual account as a product for purchasing B through the attribute tag, establishes a virtual account in the user B, sets an attribute tag "purchase product a" for the virtual account, and purchases the product a when funds enter the account through the attribute tag. After the virtual account is established for a, 100 tens of thousands of funds in the physical account are frozen. After the transfer trigger condition is reached, the blockchain transfers funds in the virtual account provided with the attribute tag of "purchasing the product of B" in the entity account of the user A into the virtual account provided with the attribute tag of "purchasing the product of A" in the entity account of the user B according to the intelligent contract, and after the transaction is completed, the funds are recorded in the blockchain script of time 3.
According to the account management method based on the blockchain, the virtual accounts formed by the transaction participants are located in the same blockchain, virtual account consensus is formed among the virtual accounts according to the business rules, intelligent contracts are formed according to the business rules, fund transfer among the virtual accounts is completed according to the intelligent contracts, special and automatic money transfer control is realized through control of the blockchain on the virtual accounts, and as the virtual accounts are all confirmed based on the blockchain, fund flow and compliance can be verified, no false account occurs, and financial risks can be prevented.
