The following describes schematically a data processing method based on a blockchain network according to an embodiment of the present invention with reference to the accompanying drawings.

Referring to fig. 3 specifically, fig. 3 is a schematic flow chart of a data processing method based on a blockchain network according to an embodiment of the present invention, where the data processing method based on a blockchain network according to the embodiment of the present invention may be executed by a data processing apparatus, where the data processing apparatus is disposed in a platform server, and the platform server includes a resource management platform, and the resource management platform is used for a publisher to publish a resource and a co-user to appreciate the published resource. Specifically, the method of the embodiment of the present invention includes the following steps.

S301: obtaining reward behavior data of a user on a target resource, wherein the reward behavior data comprises a block chain account address of a publisher of the target resource, the block chain account address of the user and a transaction amount, and the target resource carries a public key of the publisher.

In the embodiment of the invention, a platform server can acquire reward behavior data of a user on a target resource in a resource management platform, wherein the reward behavior data comprises a block chain account address of a publisher of the target resource, a block chain account address of the user and a transaction amount, and the target resource carries a public key of the publisher. In certain embodiments, the target resources include, but are not limited to, articles, pictures, video, audio, and the like.

In an embodiment, before obtaining the reward behavior data of the user for the target resource, the platform server may detect whether the user has historical reward behavior data on the resource management platform, and if the detection result is negative, may generate a private key of the user, generate a public key of the user according to the private key of the user, and send the public key and the private key of the user to the terminal device corresponding to the user, so that the user logs in the resource management platform with the public key as a login account and the private key as a password. In some embodiments, the platform server may randomly generate the private key of the user, and in other embodiments, the platform server may also generate the private key of the user in other manners, which is not limited herein.

In an embodiment, when the platform server generates the public key of the user according to the private key of the user, the platform server may calculate the private key of the user according to an elliptic curve cryptography algorithm to generate the public key of the user. In some embodiments, the elliptic curve cryptography algorithm is an existing cryptography algorithm and is not specifically set forth herein. In some embodiments, the platform server may also generate the public key of the user by using the private key of the user through other manners, which is not limited herein.

For example, when it is assumed that a platform server detects that a user approves a target resource in a resource management platform, if it is detected that historical approval behavior data does not exist on the resource management platform for the user, the user can be determined to log in the resource management platform for the first time, so that a private key of the user can be randomly generated, a public key of the user is generated by calculating the private key of the user according to an elliptic curve encryption algorithm, and the public key and the private key of the user are sent to a terminal device corresponding to the user, so that the user logs in the resource management platform with the public key as a login account and the private key as a password.

In an embodiment, before obtaining the reward behavior data of the user for the target resource, the platform server may detect whether the publisher logs in the resource management platform for the first time, and if the detection result is yes, may generate a private key of the publisher, generate a public key of the publisher according to the private key of the publisher, and send the public key and the private key of the publisher to the terminal device corresponding to the publisher, so that the publisher logs in the resource management platform with the public key as a login account and the private key as a password. In some embodiments, the platform server may randomly generate the private key of the publisher, and in other embodiments, the platform server may also generate the private key of the publisher in other manners, which is not limited herein.

In an embodiment, when the platform server generates the public key of the publisher according to the private key of the publisher, the platform server may calculate the private key of the publisher according to an elliptic curve cryptography algorithm to generate the public key of the publisher. In some embodiments, the elliptic curve cryptography algorithm is an existing cryptography algorithm and is not specifically set forth herein. In some embodiments, the platform server may also generate the public key of the publisher by using the private key of the publisher in other manners, which is not limited herein. The example of the specific embodiment is similar to the foregoing example of generating the public key of the user according to the private key of the user, and is not described herein again.

In an embodiment, before obtaining the reward behavior data of the user for the target resource, the platform server may further obtain, when detecting the reward behavior operation of the user for the target resource, a transaction amount corresponding to the reward behavior operation, query an asset balance of a blockchain account of the user from a node of the blockchain network according to a blockchain account address of the user, detect whether the asset balance is greater than or equal to the transaction amount, and if the detection result is negative, send a recharge notification message to a terminal device corresponding to the user, where the recharge notification message is used to notify the user to recharge the blockchain account of the user. In some embodiments, the recharge notification message may carry a recharge amount, where the recharge amount is used to notify the user of a minimum recharge amount for performing a reward action operation on the target resource. In some embodiments, the favorable behavior operation may be a selection operation of a favorable icon on an interactive interface with the platform server in the terminal device corresponding to the user by the user, and in other embodiments, the favorable behavior operation may also be another operation on an interactive interface with the platform server in the terminal device corresponding to the user, which is not specifically limited herein.

For example, assuming that a platform server obtains a transaction amount corresponding to a reward behavior operation when detecting the reward behavior operation of the user on the target resource, if the platform server queries, according to a blockchain account address of the user, that an asset balance of a blockchain account of the user is Y from a node of the blockchain network, and detects that the asset balance Y is less than the transaction amount X, the platform server may send a recharge notification message to a terminal device corresponding to the user to notify the user to recharge the blockchain account of the user.

By the implementation mode, the problem that the target resource issued on the resource management platform on the platform server cannot be appreciated due to insufficient balance in the block chain account of the user can be avoided, and the effectiveness of the user in appreciating the resource is improved.

In one embodiment, after the user recharges the user's blockchain account, the platform server may generate a recharge record according to the user's blockchain account address, recharge amount, and asset balance, and send the recharge record to the blockchain network to synchronize the recharge record in each node of the blockchain network. By the implementation, the reliability and the safety of recharging the user's blockchain account by the user can be ensured.

S302: and encrypting the appreciation behavior data by utilizing the public key of the publisher and the private key of the user to generate transaction data to be processed.

In the embodiment of the present invention, the platform server may encrypt the reward behavior data by using the public key of the publisher and the private key of the user, so as to generate the transaction data to be processed.

In one embodiment, when the platform server encrypts the reward behavior data by using the public key of the publisher and the private key of the user to generate the transaction data to be processed, the platform server may encrypt the blockchain account address of the publisher and the blockchain account address of the user by using the public key of the publisher and encrypt the transaction amount by using the private key of the user, so as to generate the transaction data to be processed according to the encrypted blockchain account address of the publisher, the encrypted blockchain account address of the user, and the encrypted transaction amount.

The public key of the publisher is used for encrypting the blockchain account address of the publisher and the blockchain account address of the user, and the private key of the user is used for encrypting the transaction amount, so that the security of the transaction data to be processed can be improved.

S303: and sending the transaction data to be processed to a node of the blockchain network, so that after the node decrypts the transaction data to be processed to obtain the appreciation behavior data, the assets in the blockchain account of the publisher and the assets in the blockchain account of the user are adjusted according to the blockchain account address of the publisher, the blockchain account address of the user and the transaction amount.

In this embodiment of the present invention, the platform server may send the transaction data to be processed to a node of the blockchain network, so that after the node decrypts the transaction data to be processed to obtain the reward behavior data, the node adjusts the asset in the blockchain account of the publisher and the asset in the blockchain account of the user according to the blockchain account address of the publisher, the blockchain account address of the user, and the transaction amount, generates an adjustment record, and writes the transaction data to be processed and the adjustment record into a blockchain after the common identification verification of the transaction data to be processed and the adjustment record with other nodes of the blockchain network passes. In some embodiments, the adjustment record includes change information for assets in the publisher's blockchain account, as well as change information for assets in the user's blockchain account.
