then, the transaction expenditure node encrypts each revenue data by using a HIBE hierarchical identity-based encryption manner, so that each revenue data can only be decrypted by each node on a collection path corresponding to each revenue data, and the rest nodes in the blockchain network cannot decrypt the revenue data, so as to ensure the privacy of the transaction, the encrypted first transaction data is the first encrypted transaction data, wherein the collection path is a hierarchical progressive path from the first monitoring node to the collection node, as shown in fig. 4, a multi-layer monitoring organization architecture form among the nodes in an exemplary blockchain network is used to further describe the concepts of the collection path, the expenditure path and the first monitoring mechanism, for example, assuming that the hosting mechanism 1 needs to pay 2 units to the hosting mechanism 4, at this time, the hosting mechanism a is the first monitoring mechanism of the hosting mechanism 1 and the hosting mechanism 4, the collection path is the hosting mechanism A, the hosting mechanism b and the hosting mechanism 4, and the payment path is the hosting mechanism 1, the hosting mechanism a and the hosting mechanism A.
After first encrypted transaction data are generated at a transaction expenditure node, the first encrypted transaction data are approved and signed layer by layer according to a preset expenditure path until the first encrypted transaction data are received by a first supervision mechanism;
after receiving the first encrypted transaction data, the first monitoring mechanism decrypts the first encrypted transaction data to obtain first transaction data; then the first supervision organization can check whether the balance of the first transaction data, the validity of the signature and the like are valid, and if so, the first encrypted transaction data is linked up;
if the first encrypted transaction data is identified on the chain, the regional inter-chain network sends the first encrypted transaction data which has achieved the identity to each node in the block chain network, and the first encrypted transaction data which has achieved the identity is called as second encrypted transaction data;
a receiving node corresponding to any one of the plurality of revenue data can decrypt only one revenue data corresponding to the receiving node after receiving the second encrypted transaction data;
the method comprises the following steps that S1, a collection node receives second encrypted transaction data sent by a blockchain network, wherein the second encrypted transaction data comprises a plurality of income data, and the second encrypted transaction data is encrypted and has a transaction detail which is agreed on the blockchain network;
s2, the collection node decrypts the second encrypted transaction data according to the identity key of the collection node, if the second encrypted transaction data can be decrypted, the transaction is related to the collection node, meanwhile, a piece of income data can be obtained after the transaction is decrypted, and if the second encrypted transaction data cannot be decrypted, the transaction is not related to the collection node;
and S3, the collection node changes a local account book corresponding to the collection node according to the income data obtained by decryption, wherein the fact that only one income data related to the collection node can be decrypted and other income data cannot be decrypted under the condition that the collection node is related to the transaction is stated, and the privacy of each collection node is effectively protected.
Wherein in step S3, the method further comprises:
step S31, calling the corresponding income data and the local account book, wherein the corresponding income data comprises a first income account and a first income denomination, and the local account book comprises a plurality of user account books;
step S32, finding a first user account book in the local account book according to the first income account, wherein the first user account book is a user account book corresponding to the first income account, the first user account book comprises a first account book signature, and the first account book signature is used for verifying whether user information and user balance corresponding to the first user account book are falsified;
s33, calling a first account book signature, checking whether the current user balance in the first user account book is valid according to the first account book signature, if the user balance is valid, indicating that the balance in the account book is not tampered, and then adding a first income denomination to the user balance;
s34, signing the account book of the first user according to the current balance and the user information, wherein the account book needs to be re-signed after being changed each time;
and S35, generating a bookkeeping detail according to the corresponding income data, recording the bookkeeping detail in the flow record in the local book, and balancing mutual reconciliation credence among the nodes in the later period and trial calculation inside the nodes in the later period.
After step S3, the method further includes:
s4, calling the local account book, wherein the local account book comprises running records and comprises total liabilities and total balances;
s5, intercepting all accounting details in a preset time period on the flow record to obtain a first sub-flow record;
and S6, generating a balance report and a first reconciliation report according to the first sub-flow record, the total balance and the total liability, wherein the balance report is used for checking balance of income and expense, and the first reconciliation report is used for reconciliation check with other nodes in the block chain network.
In step S6, after generating the balance report, the method further includes:
and S7, the collection node checks the balance state of the balance in the preset time period according to the balance report, and if the balance state of the balance is an unbalanced state, early warning data is sent to a terminal of a corresponding technician, and the early warning data is used for requesting the corresponding technician to intervene in investigation.
In step S6, after generating the first reconciliation report, the method further includes:
s81, acquiring second account checking reports sent by other nodes in the block chain network;
s82, comparing whether the second reconciliation report is completely the same as the first reconciliation report, if so, intercepting difference details, wherein the difference details are a plurality of transaction detail numbers of the second reconciliation report, which are different from the first reconciliation report;
s83, sending the difference detail to a second supervision node, wherein the second supervision node records each transaction data on a blockchain network, and the difference detail is used for triggering the second supervision node to call a plurality of corresponding third transaction data according to the transaction detail numbers and sending the corresponding third transaction data to a request node;
step S84, receiving a plurality of third transaction data sent by the second supervision node;
s85, changing the first reconciliation report according to the third transaction data;
step S86, the local account book is changed according to the third transaction data.
