Example 1

As shown in fig. 1, the present embodiment provides a method for supervising a blockchain transaction based on a UTXO, which includes steps S1, S2, S3 and S4.

The method comprises the following steps that S1, first encrypted transaction data submitted by subordinate transaction expenditure nodes are received;

which comprises the following steps:

s11, a subordinate transaction expenditure node firstly extracts an expenditure UTXO from an account of the subordinate transaction expenditure node, then edits payee information, and further generates a plurality of income party data (two income party data are used for explaining the embodiment), wherein one income party data corresponds to one payee user;

s12, the subordinate transaction expenditure nodes respectively encrypt 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 collection path corresponding to each income party data, and the rest nodes in the block chain network cannot decrypt the income party data, so that the privacy of the transaction is guaranteed, wherein the collection path is a hierarchical progressive path from a first supervision node to a collection node;

step S13, the subordinate transaction expenditure node encrypts the expenditure UTXO by using a HIBE hierarchical identity-based encryption mode, so that the expenditure UTXO can be decrypted only by each node on an expenditure path, and meanwhile, the following description is that: the execution parts of the step S12 and the step S13 are in sequence at the subordinate transaction expenditure node, wherein the expenditure path is a hierarchical progressive line reflecting the subordinate transaction expenditure node to the first supervision node;

for example, in step S12 and step S13, as shown in fig. 4, it is assumed that the hosting organization 1 needs to pay 2 units to the hosting organization 4, at this time, the hosting organization a is a common parent node of the hosting organizations 1 and 4, the collection path in step S12 is hosting organization a-hosting organization b-hosting organization 4, and the payment path in step S13 is hosting organization 1-hosting organization a.

Through steps S12 and S13, the subordinate transaction expenditure node generates a first encrypted transaction data;

s14, the subordinate transaction expenditure node performs corresponding signature operation on the generated first encrypted transaction data, wherein the signature corresponding to the subordinate transaction expenditure node is included in the first encrypted transaction data;

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

s16, the corresponding upper-layer node checks the validity of the signature of the subordinate transaction expenditure node, if the signature is valid, the signature is continued, and the corresponding signature is added to the first encrypted transaction data;

and S17, the corresponding upper node sends first encrypted transaction data to a higher upper node corresponding to the corresponding upper node according to the expenditure path, and in the same way, 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 receipt and payment details of the transaction.

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

step S31, calling the first transaction data, wherein the first transaction data comprises expenditure UTXO and two income party data, and the income party data reflects collection information of a collection party;

step S32, checking the validity of the expenditure UTXO (all valid UTXOs are included in the block chain network), and if the expenditure UTXO is valid, detecting the balance of income data, wherein the specific operation step of detecting the balance of income data comprises the following steps:

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

step S322, calling the two income party data, wherein the income party data comprises income accounts and to-be-collected denominations;

step S323, the effectiveness of each income account is sequentially checked, and if the two income accounts are both effective accounts, the sum of the two to-be-collected denominations is counted to obtain income denominations;

step S324, comparing whether the income denomination is the same as the expenditure denomination;

step S325, if the income denomination is the same as the expenditure denomination, determining that the balance of the income and expenditure of the first transaction data is in a balance state;

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

s33, calling the first transaction data, wherein the first transaction data comprises a cost UTXO;

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

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

In one aspect, it should be noted that in step S32, the validity of the payout UTXO is checked, and if the payout UTXO is invalid (i.e., the UTXO is not present in the blockchain network or is already in use), the first supervisory node sends a first transaction failure report to the subordinate transaction payout node;

after receiving the first transaction failure report, the subordinate transaction expenditure node firstly detects the validity of the expenditure UTXO by itself, starts a system internal self-checking program after confirming invalidity, detects relevant information of the invalid UTXO, such as the user account number, the time for storing the account number and the like, and informs relevant business personnel to contact a customer; and backing up the first transaction data; meanwhile, a failure transaction report is generated and sent to each node on the expenditure path, the failure transaction report is used for announcing all nodes on the expenditure path, the subordinate transaction expenditure nodes have cheated transactions together, and all nodes on the expenditure path can record a first transaction failure report; once the submitted transaction fails, the system considers that the transaction is a fraudulent transaction, specific information of the failed transaction needs to be reflected to relevant organizations, and meanwhile, a system vulnerability causing establishment of the fraudulent transaction is searched for and used as a backup, so that later-stage updating of the system is facilitated;

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

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

after receiving the second transaction failure report, the subordinate transaction expenditure node firstly detects the validity of the expenditure UTXO by itself, starts a system internal self-checking program after confirming the invalidity, detects the relevant information of the invalid UTXO, such as the user account number, the time for storing the account number and the like, and informs relevant business personnel to contact the customer; and backing up the first transaction data; meanwhile, a failure transaction report is generated and sent to each node on the expenditure path, the failure transaction report is used for announcing all nodes on the expenditure path, the subordinate transaction expenditure nodes have cheated transactions together, and all nodes on the expenditure path can record a second transaction failure report; once the submitted transaction fails, the system considers that the transaction is a fraudulent transaction, specific information of the failed transaction needs to be reflected to relevant organizations, and meanwhile, a system vulnerability causing establishment of the fraudulent transaction is searched for and used as a backup, so that later-stage updating of the system is facilitated;

meanwhile, the first supervision node sends the second transaction failure report to a second supervision node (an organization node of a government supervision layer), and the second supervision node gives corresponding penalties to the users under the subordinate transaction expenditure nodes or the subordinate transaction expenditure nodes according to the information such as the type and the amount 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 expenditure UTXO is valid, and if the signature is invalid, the first supervising node sends a third transaction failure report to the subordinate transaction expenditure node;

after receiving the third transaction failure report, the subordinate transaction expenditure node firstly detects the validity of the expenditure UTXO by itself, starts a system internal self-checking program after confirming the invalidity, detects the relevant information of the invalid UTXO, such as the user account number, the time for storing the account number and the like, and informs relevant business personnel to contact the customer; and backing up the first transaction data; meanwhile, a failure transaction report is generated and sent to each node on the expenditure path, the failure transaction report is used for announcing all nodes on the expenditure path, the subordinate transaction expenditure nodes have cheated transactions together, and all nodes on the expenditure path can record a third transaction failure report; once the submitted transaction fails, the system considers that the transaction is a fraudulent transaction, specific information of the failed transaction needs to be reflected to relevant organizations, and meanwhile, a system vulnerability causing establishment of the fraudulent transaction is searched for and used as a backup, so that later-stage updating of the system is facilitated;

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

Example 2

s51, acquiring a supervision rule, wherein the supervision rule is a character 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 block chain network, wherein the first intelligent contract is used for triggering the block chain network to detect whether the first transaction data meet the supervision rule, and if the first transaction data meet the supervision rule, executing consensus voting operation;

step S54, second encrypted transaction data on the blockchain network are obtained, wherein the second encrypted transaction data are first encrypted transaction data which are agreed and executed on the blockchain network;

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

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