A plurality of transaction records are recorded in each block, and the transaction records also comprise the hash (hash) value of the previous block, and all blocks store the hash value of the previous block in the way and are connected in sequence to form a block chain. The hash value of the previous block is stored in the block head of the next block in the block chain, and when the transaction data in the current block changes, the hash value of the block is changed, so that the transaction data uploaded to the block chain network is difficult to tamper, the transaction between the client and the service platform is carried out on the block chain, the transaction process is transparent, and the reliability of the transaction data is improved.

For example, when a fund mutual contribution apportionment event occurs, the mutual contribution event, i.e. the apportioned amount, is sent to the chain in the form of a transaction, and the transaction content (i.e. the seventh transaction data) includes the mutual contribution event information, the user platform account number and the apportioned amount (i.e. the target electronic resource).

S412: and the first block chain node equipment carries out uplink processing on the seventh transaction data.

During specific implementation, the first block chain node equipment judges whether a sixth preset database contains a user platform account; if the first block chain node point device judges that the sixth preset database contains the user platform account, the first block chain node point device compares the balance of the account with the apportioned amount; and if the balance of the account is larger than the apportioned amount, the first block chain node equipment transfers the target electronic resource from the mutual account to a user account of the client, and generates the description information of the target electronic resource.

In one implementation, the uplink processing of the seventh transaction data by the first blockchain node device includes: the first block chain link point device verifies the seventh transaction data; after the first block chain link point device successfully verifies the seventh transaction data, the first block chain link point device sends the seventh transaction data to each second block chain link point device in the block chain network, so that each second block chain link point device performs block chain consensus on the seventh transaction data; when the block chain consensus passes, the first block chain link point device generates a block from the seventh transaction data; the first block-link point device publishes the block into the block chain network to which the first block-link point device belongs.

For example, in the execution process, an intelligent contract is called to start a mutual contribution sharing process, the first block link node equipment inquires whether an account number of a user platform exists or not, and if not, an execution failure result is returned; if yes, checking whether the balance of the account is enough to deduct the apportioned amount, and if not, returning an execution failure result; if the balance is sufficient, deducting the allocated amount, and simultaneously recording fund allocation events, namely mutual events and the allocated amount.

S413: the first block link point device sends the mutual aid event to the client and the mutual aid platform.

For example, the first tile link point device sends the target electronic resource and description information of the target electronic resource to the client and the mutual aid platform. The user can inquire the mutual aid record through the platform account number and inquire the fund sharing record through the block chain, and the fund data risk is checked.

The embodiment of the application provides a data processing method, which realizes the management of mutual-aid insurance business based on a block chain technology, and the method ensures that the management process of the insurance business is open and transparent, and has the witnesses of a plurality of block chain node devices, thereby improving the public credibility of insurance business data; meanwhile, after the user signs a mutual-help insurance plan contract with the mutual-help platform, a fund mutual-help allocation event can be carried out on the block chain, and the phenomenon that illegal persons profit from the fund mutual-help allocation event in the prior art is avoided.

S506: and the first block link point equipment carries out uplink processing on the second transaction data.

S507: and the first block chain node point equipment sends the signing result to the client and the service platform.

Steps S501 to S507 in this embodiment may specifically refer to the execution processes of steps S301 to S307 in the above embodiment, and this embodiment of the present invention is not described again.

S508: and the first block chain node equipment receives eighth transaction data sent by the service platform.

The eighth transaction data includes the contract return data, and the specific execution process of the first block link point device may refer to the execution process of the first block link point device in step S301. For example, in the application scenario of the travel service, the travel agency (i.e., the service platform) digitally signs the travel service performance information in the form of transaction and sends the digitally signed travel service performance information to the block chain, and the transaction content (i.e., the eighth transaction data) mainly includes the user ID, the published travel route summary hash, the travel service contract performance information (i.e., the contract data), the travel service order number, the enterprise certificate summary hash, and the public key.

For example, after the first block link node device receives the transaction, the validity of the transaction signature is verified through a public key, and after the verification is passed, the virtual machine is called to execute the transaction; in the execution process, calling an intelligent contract to start a travel service termination flow; the first block link point equipment checks whether the summary hash of the tourist route information can find the issued tourist route and whether the summary hash generated by the tourist route data is the same as the summary hash in the transaction, and if the check fails, an execution failure result is returned; checking whether the order number exists and whether the order number state is a valid state, and if the checking fails, returning an execution failure result; the certificate is inquired through the enterprise certificate abstract hash, and if the inquiry fails, an execution failure result is returned; and comparing whether the public key in the certificate is consistent with the public key information in the transaction, and if not, returning an execution failure result.

And if and only if the verification is successful, the first block link point equipment sets the order number state as the order of the travel agency, adds the travel service contract performance information and the travel agency transaction hash information into the order content, and writes the order content into the intelligent contract. The first block chain link point device sends the eighth transaction data to each second block chain link point device in the block chain network, so that each second block chain link point device performs block chain consensus on the eighth transaction data; when the block chain consensus passes, the first block chain link point device generates a block from the eighth transaction data; the first block-link point device publishes the block into the block chain network to which the first block-link point device belongs.

S511: and the service platform sends the summary hash of the eighth transaction data to the client.

S512: and the first block chain link point device receives ninth transaction data sent by the client.

For example, the user inquires whether the travel service contract performance information and the order status on the chain are consistent with the content displayed by the travel agency through the order number, if so, the user digitally signs the contract performance termination information and sends the information to the block chain in a transaction form, and the transaction content (i.e., the ninth transaction data) includes the user ID, the issued travel route summary hash, the travel service order number, the transaction hash, and the user certificate and public key information.

S513: and the first block chain node equipment carries out uplink processing on the ninth transaction data.

For example, after the blockchain receives the transaction, the validity of the transaction signature is verified through the public key, and the transaction is executed after the verification is passed; in the execution process, calling an intelligent contract to start a contract termination flow of a user; checking whether the travel route information abstract hash can find the issued travel route and whether the abstract hash generated by the travel route information is the same as the abstract hash in the transaction, and if the check fails, returning an execution failure result; checking whether the order number exists or not, and if not, returning an execution failure result; inquiring the specific content of the order through the order number, comparing whether the transaction hash of the travel agency termination contract in the order content stored by the intelligent contract is consistent with the transaction hash of the user contract termination transaction content, and if not, returning an execution failure result; checking whether the transaction state is the bill of the travel agency, and if not, returning an execution failure result; checking whether the user IDs are consistent, if not, returning an execution failure result; the certificate is inquired through the user certificate abstract hash, and if the inquiry fails, an execution failure result is returned; comparing whether the public key in the certificate is consistent with the public key information in the transaction, and if not, returning an execution failure result;

and if and only if the verification is passed, the first block link point equipment updates the order content, updates the order state to be that the travel service contract is completed, adds a user contract to terminate transaction hash, and writes the transaction hash into an intelligent contract. The first block chain link point device sends the ninth transaction data to each second block chain link point device in the block chain network, so that each second block chain link point device performs block chain consensus on the ninth transaction data; when the block chain consensus passes, the first block chain link point device generates a block from the ninth transaction data; the first block-link point device publishes the block into the block chain network to which the first block-link point device belongs.

And after the CA mechanism performs real-name authentication on the received application, issuing a user certificate to the investor, packaging the certificate into a transaction, and sending the transaction to the first block link point equipment. After the first block link node device receives the transaction (namely, the fourth transaction data), the validity of the transaction is verified, mainly the CA mechanism digitally signs the transaction, and the virtual machine is called to execute the transaction after the verification is passed. In the execution process of the first block chain node equipment, calling an intelligent contract to start certificate storage, firstly performing summary hash calculation on the certificate, then inquiring whether the certificate exists through the summary hash, and if so, returning an execution failure result. After the verification is passed, the first block chain node equipment takes the digest hash as a Key, and writes the certificate as a Value into an intelligent contract. When the blockchain consensus passes, the first blockchain link point device generates a block from the fourth transaction data. The first block-link point device publishes the block into the block chain network to which the first block-link point device belongs. The first block chain node equipment returns the uplink result and the certificate digest hash (namely, the digest hash of the user certificate) to the CA mechanism; the CA authority returns the user certificate and the certificate digest hash to the investor, who stores the user certificate and the certificate digest hash.

Wherein the uplink result is uplink success or uplink failure. When the condition that the user certificate does not exist on the intelligent contract and the block chain link point equipment passes the block chain consensus of the user certificate is met, the uplink is successful; and when the user certificate exists on the intelligent contract or when the user certificate does not exist on the intelligent contract, the block chain link point equipment fails to pass the block chain consensus of the user certificate, namely the uplink failure is determined.

Wherein the uplink result is uplink success or uplink failure. When the condition that the service platform certificate does not exist on the intelligent contract and the block chain link point equipment passes the block chain consensus of the service platform certificate is met, the uplink is successful; and when the service platform certificate exists on the intelligent contract or when the service platform certificate does not exist on the intelligent contract, the block chain link point equipment does not pass the block chain consensus of the service platform certificate, namely the uplink failure.
