the method comprises the following steps:

step S11, firstly, extracting a payment UTXO from an account of a subordinate transaction payment node, and then editing information of a payee to generate a plurality of pieces of income party data (the embodiment is described by two pieces of income party data), wherein one piece of income party data corresponds to one payee user;

step S12, the subordinate transaction expenditure node encrypts each income party data by using a HIBE hierarchical identity-based encryption mode, so that each income party data can only be decrypted by each node on a corresponding collection path, other nodes in the blockchain network can not decrypt the income party data, and the privacy of the transaction is guaranteed, wherein the collection path is a hierarchical progressive path of a first supervision node to a collection node;

step S13, encrypting the payment UTXO by the subordinate transaction payment node in a HIBE layered identity-based encryption mode, so that the payment UTXO can only be decrypted by each node on a payment path, and meanwhile, the following should be noted: step S12 and step S13 are performed in sequence on the execution part of subordinate transaction expenditure nodes, wherein the expenditure path is a hierarchical progressive line for reflecting the subordinate transaction expenditure nodes to the first supervision node;

for example, step S12 and step S13 are illustrated, and as shown in fig. 4, assuming that the hosting mechanism 1 needs to pay 2 yuan to the hosting mechanism 4, at this time, the hosting mechanism a is a common parent node of the hosting mechanism 1 and the hosting mechanism 4, the collection path in step S12 is a hosting mechanism a-hosting mechanism b-hosting mechanism 4, and the payout path in step S13 is a hosting mechanism 1-a-hosting mechanism a.

The subordinate transaction payout node generates first encrypted transaction data through the steps S12 and S13;

s14, performing corresponding signature operation on the generated first encrypted transaction data by the subordinate transaction expenditure node, wherein the first encrypted transaction data comprises a signature corresponding to the subordinate transaction expenditure node;

s15, the subordinate transaction expenditure node sends the first encrypted transaction data to the upper node corresponding to the subordinate transaction expenditure node;

s16, checking the validity of the signature of the subordinate transaction expenditure node by the corresponding upper node, if so, continuing, and adding the corresponding signature to the first encrypted transaction data;

and S17, the corresponding upper node sends first encrypted transaction data to the higher upper node corresponding to the corresponding upper node according to the expenditure path, and the first encrypted transaction data is verified, signed and uploaded layer by layer and finally sent to the first supervision node.

S2, the first supervision node decrypts the first encrypted transaction data to obtain first transaction data, and the first transaction data reflects the balance detail of the transaction.

S3, a first supervision node detects the balance of the first transaction data and the validity of the signature in the first transaction data, wherein the detection of the balance of the first transaction data specifically comprises the following steps:

s31, calling the first transaction data, wherein the first transaction data comprises a expenditure UTXO and two income party data, and the income party data reflects the collection information of a collection party;

step S32, checking the validity of the expenditure UTXO (the blockchain network comprises all valid UTXOs), and if the expenditure UTXO is valid, detecting the balance of the income data, wherein the specific operation steps of detecting the balance of the income data comprise:

s321, detecting the denomination of the expenditure UTXO to obtain the expenditure denomination;

s322, calling the two income party data, wherein the income party data comprises income accounts and denominations to be collected;

step S323, sequentially checking the validity of each income account, and if the two income accounts are valid accounts, counting the sum of the two denominations to be collected to obtain income denominations;

step S324, comparing whether the income denomination and the expenditure denomination are the same;

s325, if the income denomination is the same as the expenditure denomination, judging that the balance of the first transaction data is in a balance state;

in step S3, the specific step of detecting the signature validity of the first transaction data includes:

s33, retrieving the first transaction data, wherein the first transaction data comprises a expenditure UTXO;

and S34, checking whether the signature of the expenditure UTXO is valid, and if the signature of the expenditure UTXO is valid, judging that the signature of the transaction data is valid.

And S4, if the balance and the signature of the first transaction data are normal, the first supervision node signs the first transaction data and then uploads the first encrypted transaction data to a blockchain network.

In one aspect, it should be noted that in step S32, the validity of the disbursement UTXOs is checked, and if the disbursement UTXOs are invalid (i.e., there is no UTXO in the blockchain network or the UTXO has been used), the first supervising node sends a first transaction failure report to the subordinate transaction disbursement node;

after receiving the first transaction failure report, the subordinate transaction expenditure node firstly detects the validity of the expenditure UTXO, after confirming invalidation, starts a self-checking program in the system, detects the related information of the invalidated UTXO, such as the user account number, the account deposit time and the like, and informs related business personnel to contact customers; and backing up the first transaction data; meanwhile, generating a failed transaction report and sending the failed transaction report to each node on the expenditure path, wherein the failed transaction report is used for notifying all nodes on the expenditure path, the subordinate transaction expenditure nodes generate fraudulent transactions together, and all nodes on the expenditure path record a first transaction failure report; that is, once the submitted transaction fails, the system considers the transaction as a fraudulent transaction, and needs to respond specific information of the failed transaction to a related mechanism, and searches for a system vulnerability which causes the fraudulent transaction to be established, and the system vulnerability is used as a backup, so that the later updating of the system is facilitated;

meanwhile, the first supervision node sends the first transaction failure report to the second supervision node (the agency node of the government supervision level), and the second supervision node gives corresponding penalties to the subordinate transaction expenditure node or the user under the subordinate transaction expenditure node according to the information such as the type, the amount and the like of the transaction in the first transaction failure report.

In a second aspect, it should be noted that, in step S325, if the revenue denomination is not the same as the payout denomination, the first supervising node sends a second transaction failure report to the subordinate transaction payout node;

after receiving the second transaction failure report, the subordinate transaction expenditure node firstly detects the validity of the expenditure UTXO, after confirming invalidation, starts a self-checking program in the system, detects the related information of the invalidated UTXO, such as the user account number, the account deposit time and the like, and informs related business personnel to contact customers; and backing up the first transaction data; meanwhile, generating a failed transaction report and sending the failed transaction report to each node on the expenditure path, wherein the failed transaction report is used for notifying all nodes on the expenditure path, the subordinate transaction expenditure nodes generate fraudulent transactions together, and all nodes on the expenditure path record a second transaction failure report; that is, once the submitted transaction fails, the system considers the transaction as a fraudulent transaction, and needs to respond specific information of the failed transaction to a related mechanism, and searches for a system vulnerability which causes the fraudulent transaction to be established, and the system vulnerability is used as a backup, so that the later updating of the system is facilitated;

meanwhile, the first supervision node sends a second transaction failure report to a second supervision node (an organization node of a government supervision level), and the second supervision node gives corresponding penalties to users under subordinate transaction expenditure nodes or subordinate transaction expenditure nodes according to the type, amount and other information of the transaction in the second transaction failure report.

In a third aspect, it should be noted that in step S34, it is checked whether the signature of the payment UTXO is valid, and if the signature is invalid, the first supervising node sends a third transaction failure report to the subordinate transaction payment node;

after receiving a third transaction failure report, the subordinate transaction expenditure node firstly detects the validity of the expenditure UTXO, starts a self-checking program in the system after confirming invalidation, detects the related information of the invalidated UTXO, such as the user account number, the account deposit time and the like, and informs related business personnel to contact customers; and backing up the first transaction data; meanwhile, generating a failed transaction report and sending the failed transaction report to each node on the expenditure path, wherein the failed transaction report is used for notifying all nodes on the expenditure path, the subordinate transaction expenditure nodes generate fraudulent transactions together, and all nodes on the expenditure path record a third transaction failure report; that is, once the submitted transaction fails, the system considers the transaction as a fraudulent transaction, and needs to respond specific information of the failed transaction to a related mechanism, and searches for a system vulnerability which causes the fraudulent transaction to be established, and the system vulnerability is used as a backup, so that the later updating of the system is facilitated;

meanwhile, the first supervision node sends the third transaction failure report to the second supervision node (the agency node of the government supervision level), and the second supervision node gives corresponding penalties to the subordinate transaction expenditure node or the user under the subordinate transaction expenditure node according to the information such as the type, the amount and the like of the transaction in the third transaction failure report.

Example 2

Based on embodiment 1, after the first supervision node uploads the first encrypted transaction data to the blockchain network, the second supervision node (the second supervision node is a node for monitoring whether the first transaction data meets the supervision rule, as shown in fig. 4, an exemplary intermediate debt-log node may be a second supervision node) will automatically perform the following steps:

s51, acquiring a supervision rule, wherein the supervision rule is a word for specifying a transaction mode;

s52, generating a first intelligent contract according to the supervision rule;

step S53, uploading the first intelligent contract to the blockchain network, wherein the first intelligent contract is used for triggering the blockchain network to detect whether the first transaction data accords with the supervision rule, and if the first transaction data meets the supervision rule, executing consensus voting operation;

s55, decrypting the second encrypted transaction data to obtain second transaction data;

and S56, saving the second transaction data, wherein the second transaction data reflects the completed transaction data.

Because the second supervision node directly acquires each transaction data from the blockchain network, the transactions among different levels can be supervised by the second supervision node, so that the penetration supervision of the second supervision node is facilitated, namely, the transactions generated by each level can be supervised.
