s3, the donor sends a donation instruction to the banking institution according to the received donation request information, and the banking institution sends the donation fund information to the block chain donation request account of the recipient; in the step, the donor enters a donation registration system, firstly enters a block chain account which passes real-name authentication and obtains displacement, secondly enters a block chain account which is directly eaten and logs in, and the third-party organization has the same principle; the donator obtains donation request information through the help-seeking public indication module, and selects the donated object to send a donation instruction to an account of a legal note escrow bank mechanism of the donated object, after the bank receives the instruction, the bank sends Token of the number of the objects to a special donation receiving block chain account of the donated object as a certificate, and the bank mechanism sends the donation fund information to the special donation receiving block chain account of the donator;
s4, the block chain donation request account is decrypted and confirmed according to respective private keys of the third-party organization and the donated persons to complete donation data processing; in this step, the receiving special donation blockchain account is controlled to decrypt and confirm to complete donation data processing according to respective private keys on the third-party general blockchain account and the help seeking blockchain account of the recipient, so as to unlock the account. The third party institution pays a treatment fee with a proper proportion for the recipient according to the Token received in the receiving special donation blockchain account, when the recipient generates a fee in the hospital actually, the third party institution initiates a multi-signature transaction to the recipient by controlling the third party total blockchain account, then the recipient confirms that the expense is generated, and signs the multi-signature transaction by using the help seeking blockchain account, and the transaction is changed from the receiving special donation blockchain account to the third party total blockchain account for transferring the Token with a corresponding quantity;
when the help block chain account of the donor and the third-party general block chain account are both signed, the multi-sign transaction is successful, and the third-party mechanism receives Token; when a hospital is to convert Token to cash, Token may be transferred to a blockchain account of the escrow bank; and after receiving the Token, the bank mechanism transfers the corresponding legal currency to a bank account appointed by a third-party mechanism, and the Token (certificate) is converted and destroyed. The Token can be DECP of a central bank or RMB stable currency, and when 1 RMB is deposited in a bank, a bank organization can issue 1Token, and after the 1Token is transferred to a bank block chain account to represent the RMB, the Token is destroyed, so that the problem of increasing and issuing currency is avoided.
By the method, when the donated people use the funds, the third-party mechanism is required to cooperate, and similarly, the third-party mechanism is also required to cooperate with the donated people, so that formal donation is avoided, and the donated funds are guaranteed to be efficiently deposited on individuals.
The donation data processing method based on the block chain is applied to an intelligent contract, and the steps of receiving a donation request account initiated by a third-party organization and a donator together and creating a corresponding block chain donation request account, encrypting donation request information by utilizing respective public keys of the two block chain donation request accounts together, forwarding the donation request information, and receiving the donation amount of the donator and a common private key of the donator and the third-party medical organization to decrypt the account are completed through the intelligent contract.
In addition, Smart contracts (English: Smart contract) are a computer protocol intended to propagate, verify or execute contracts in an informational manner. Smart contracts allow trusted transactions to be conducted without third parties, which transactions are traceable and irreversible. The structural principle of the intelligent contract belongs to the prior art, and is not described in detail herein.
The donation data processing method based on the blockchain provided by the embodiment of the invention encrypts the donation request information by using respective public keys of the blockchain donation request accounts of the third-party organization and the donators, and then decrypts the blockchain donation request accounts by using respective private keys of the third-party organization and the donators; through the method of encrypting the donation request information data and then jointly collaboratively decrypting the donation request information data, the purpose of effectively verifying the donation data is achieved, so that formal donations are avoided, high-efficiency implementation of donation funds on individuals is ensured, and the use efficiency of the funds is greatly improved.
Meanwhile, the donation data and the block chains are combined, the efficiency of capital data transfer is improved, the whole donation process is very efficient and transparent, and meanwhile, through the mode, the provable electronic donation certificate is passed for the donator, the help seeking time is shortened for people needing help, and the authenticity of seeking help and the success rate of obtaining help are improved;
all the steps are carried out on the block chain and cannot be tampered, so that the possibility that a person cheats to fetch help is avoided, even if the behavior that a hospital and a patient cheat to fetch the help is generated, once the behavior is found, the credit of the hospital suffers great loss, the cost of doing the bad work is higher, and the scheme can be further used in different fields such as education of poor students and the like.
Preferably, step S2 further includes verifying, by the regulatory body, the encrypted donation request account information before sending the donation request account information to the blockchain exposing module.
In a specific implementation, step S2 further includes verifying, by the monitoring authority, the donation request account information before sending the encrypted donation request account information to the blockchain public module. The supervision mechanism can supervise the action on the whole donation chain, and the donator can also track the use way of each good money, fully breaks the opaque phenomenon that exists in traditional philanthropic field in the past, avoids the corruption problem.
Preferably, the information data of the third party institution is provided with a first suffix; the information data of the banking institution is provided with a second suffix; the information data of the supervision institution is provided with a third suffix; the information data of the block chain donation account of the donor is provided with a fourth suffix; the block chain donation request account comprises a receiving special donation block chain account and a help block chain account; the information data of the help-seeking blockchain account is provided with a fifth suffix; and the information data of the special donation block chain account is provided with a sixth suffix.
Preferably, the first suffix is. The second suffix is bank; the third suffix is sup; the fourth suffix is. hel; the fifth suffix is. The sixth suffix is.
In specific implementation, the suffix of the information data of the third-party organization is. hos; the suffix of the information data of the bank organization is bank; the suffix of the information data of the supervision organization is sup; the suffix of the information data of the blockchain donation account of the donor is hel; the suffix of the information data of the help block chain account is pat; the suffix of the information data that receives the special donation blockchain account is.con.
In the donation data processing method based on the block chain, a bank organization is used as a main block output node, all the behaviors of registering accounts in the block chain need to be authorized, and only a third-party general block chain account at the end of hos can be created for a donator, a block chain account receiving special donation at the end of con and a block chain account receiving special donation at the end of con are controlled by hos and pat together. The bank account at the end of the bank can help the donor to create the donor account at hel, namely the donor account at the end of hel, and the supervision module is the special authority account at the end of sup.
According to the embodiment provided by the invention, the authority definition is carried out on the account at the end of different suffixes, so that the behavior on the chain is more visualized and normalized.
For example, a hospital can register only a single blockchain account in the blockchain, and the format is represented by short 8-digit letters + hos, after uploading a business license of the hospital, the hospital can successfully register the account, for example, a certain hospital yyyy registers the blockchain account aaaa. hos, and then through the publicity system, we will see that the actual name of the hospital will be displayed together with the blockchain account, and the account is permanently bound.
When a help seeker (receiver) seeking medical advice in the YYY hospital cannot pay medical expenses, the help seeker can submit relevant information through a help seeking system of the YY hospital, the hospital verifies the authenticity of the help seeker according to conditions, if the help seeker deems that the help seeker is authentic, an aaaaaaaa.hos account is used for creating aaaaaaaa.pat and aaaaaaaaaaaa.con account names, the aaaaaaaaaa.pat account names are bound with the electronic health card of the patient, and the patient can only use the aaaaaaaaaa.pat account when applying for help in other hospitals afterwards, so that a unique credit account is also created, and the occurrence of cheating is reduced to the maximum extent. At the same time, the act of the hospital creating an account for the user is also recorded on the blockchain.
After creating the patient's blockchain donation request account, the patient himself holds the private key of the blockchain account and is responsible for the account. Meanwhile, the hospital help system automatically generates a multi-account for the aaaaaaaa. pat help seeker, the multi-account is controlled by the patient and the blockchain account of the hospital together and is used for receiving the benefit, and when the benefit in the account needs to be paid, the patient and the hospital need to sign at the same time to define the authority. The end of all the multiple accounts is.con, e.g., the special account of aaaaaaaa. con is created in this example.
The help-seeking bulletin system will bulletin the donation request information according to the rule, such as donation amount, user name, third party organization name, illness state description, identification card number, block chain account name of the third party organization and user, etc.;
after obtaining the donation request information, the donor may register through the client or the donation registration system, and the donor who enters and uses for the first time needs real-name authentication to obtain a unique blockchain account, for example, the blockchain account of a certain donor is aaaaaaaa. And then the donor checks all patients needing to be donated in the block chain public display module, can select the patients, fills in a donation bill with a certain rule, such as the recipient, the amount of the recipient, whether the personal name of the donor is public or not, and transfers accounts to bank escrow accounts through different account transferring modes such as bank account transferring, payment treasure, WeChat and the like. For example, the donor aaaaaaaa. hel selected aaaaaaaaaa. pat, and donated 10 ten thousand yuan.
After the bank organization receives 10 ten thousand yuan of money transfer, an electronic donation certificate is sent to the blockchain account of the donator, and meanwhile, the bank organization transfers 10 thousand token/central row DECP to the specially-received blockchain account aaaaaaaa. con to serve as a redemption certificate.
When the hospital checks that the account aaaaaa. con has 10 ten thousand balances, the treatment of the help seeker can be started in advance, and when 1 ten thousand yuan of treatment expenditure is generated, the hospital can initiate a cash request; the request is for the hospital aaaaaaaa. hel account to initiate a multiple transaction for aaaaaaaaaaaa. con.
The patient is automatically reminded of the patient through active hospital inquiry or a hospital system, and the patient is allowed to verify whether the fee is generated, if the fee is real, the patient signs the transaction by using the aaaaaa.
After receiving 1 ten thousand tokens for example, the hospital account can perform cash-up operation, and initiates transfer to any bank block chain account ending in the bank, and after receiving the 1 ten thousand tokens, the bank block chain account transfers to the bank account designated by the hospital and destroys the 1 ten thousand tokens at the same time.
The account at the end of sup has the auditing and monitoring rights of the whole network, and because all operations are recorded on a chain, a monitoring department can perform post-hoc spot check and the like.
Preferably, the donated funds in step S3 are settled by a plurality of banks in the blockchain network, including the offline bank account number and the intelligent contract account; and exchanging according to the offline amount of the offline bank account and the online amount of the intelligent contract account.
Preferably, the method further comprises the following steps: if the donated funds exceed the donation amount in the donation request information, the exceeded amount is returned to the donor's donation account.
When the concrete implementation, still include: if the donated funds exceed the donation amount in the donation request information, the block chain account receiving the special donation returns the exceeded amount to the donation account of the donor, so that the problem of multiple donations is avoided, and the good money of the donor is prevented from being abused.
As shown in fig. 3, an embodiment of the present invention further provides a device for donation data processing based on a blockchain, the device including a processor and a memory, the processor and the memory being connected through a bus, the memory storing machine-readable code therein, and the processor executing the machine-readable code in the memory to perform the method as any one of the above.
Embodiments of the present invention also provide a computer-readable storage medium having computer program code stored thereon, which when executed by a computer performs the method as described in any of the above.
