Detailed Description
The embodiment of the invention provides a data processing method based on a block chain, which can be applied to a node of a block chain network, wherein the node can be any node accessed into the block chain network, and the node can be any form of electronic equipment, such as a server, a user terminal and the like. In one embodiment, a node may receive a proportion ticket request submitted by a terminal device, where the proportion ticket request carries proportion data of each first user included in a target user set for an asset corresponding to a target ticket, the target ticket is generated based on transaction information about the asset between a second user and each first user, and the proportion data includes a proportion of each first user to the asset. Further, the node may generate a proportion ticket for each first user included in the target user set based on the proportion data and the target ticket, write the identification information of each first user and the corresponding proportion ticket into the block chain, and send the proportion ticket of each first user to the terminal device corresponding to each first user, and each subsequent first user may declare ownership (i.e., proportion) of the asset based on the proportion ticket of each subsequent first user. The first user may be a buyer who purchases the asset, and the second user may be a seller who sells the asset. According to the embodiment of the invention, the ownership management of each first user for the assets is realized through the block chain in combination with the non-tamper-proof property of the block chain, so that the problems of the existing ownership management process that the ownership is easily tampered are solved, and the accuracy and the reliability of ownership determination are favorably improved.
The Block Chain (Block Chain) is a Chain data structure which combines data blocks in a sequential connection mode according to a time sequence and is a distributed book which is cryptographically used for ensuring that the data cannot be tampered and forged. Multiple independent distributed nodes (i.e., block-linked node devices) maintain the same record. The blockchain technology realizes decentralization and becomes a foundation for credible digital asset storage, transfer and transaction.
Taking the block chain structure diagram shown in fig. 1 as an example, when new data needs to be written into the block chain, the data is collected into a block (block) and added to the end of the existing block chain, and the newly added block of each node is ensured to be identical through a consensus algorithm. 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 is carried out on the block chain, the transaction process is transparent, and the reliability of the transaction data is improved.

The first node 202 may also be obtained by periodic election through a consensus algorithm, and the first nodes 202 obtained by different periodic elections may be the same or different.
In one embodiment, after the second user performs an asset transaction with each first user in the target user set, the second user may upload, through the terminal device 202, invoicing data related to the asset transaction to the first node 202 in the blockchain network, and the first node 202 may generate a target ticket for the asset based on the invoicing data and write the target ticket into the blockchain. Further, any one of the first users may submit a proportion bill request for the target bill through the terminal device 201, where the proportion bill request carries proportion data of the first user for an asset corresponding to the target bill, and the proportion data includes a proportion of the first user to the asset. Further, after receiving the duty ticket request, the first node 202 may generate a duty ticket for each first user based on the duty data and the target ticket, write the identification information of each first user and the corresponding duty ticket into the block chain, send the duty ticket of each first user to the terminal device 201 corresponding to each first user, and each subsequent first user may view its own duty ticket through the terminal device 201 and declare its own ownership of the asset based on its own duty ticket.

In one embodiment, after the second user performs asset transaction with each first user in the target user set, the second user may upload, through a terminal device, invoicing data related to the asset transaction to a node of a blockchain network, where the node may generate a target ticket for the asset based on the invoicing data, and write the target ticket into a blockchain. Each first user in the target user set may refer to all buyers (i.e., owners) who purchase the assets, and the second user may refer to a seller who sells the assets.
Further, in an embodiment, after the target ticket is written into the block chain, each first user in the target user set may agree on the occupation ratio of the first user to the asset, generate occupation ratio data for the asset corresponding to the target ticket, and digitally sign the occupation ratio data based on a private key of the first user. In this case, the digitally signed percentage data includes the digital signature of each first user, before the node generates one percentage ticket for each first user included in the target user set based on the percentage data and the target ticket, the node may also verify the digital signature of each first user based on the public key of each first user, and when the node passes the verification of the digital signature of each first user, the following step S302 is triggered to be executed.

S303: and the node writes the identification information of each first user and the corresponding proportion bill into the block chain, and sends the proportion bill of each first user to the terminal equipment corresponding to each first user.
In one implementation, the node may perform consensus verification on the identification information of each first user and the corresponding proportion ticket, and if the consensus verification passes, the node generates a new block corresponding to the identification information of each first user and the corresponding proportion ticket, and adds the new block to the block chain.
The specific implementation manner of performing consensus verification on the identification information of each first user and the corresponding proportion bill by the node may be that the node sends the identification information of each first user and the corresponding proportion bill to other nodes in the block chain network, the other nodes may perform block chain consensus on the identification information of each first user and the corresponding proportion bill, and if the identification information of each first user and the corresponding proportion bill are confirmed to pass by more than a preset number of other nodes in the block chain network, it is determined that the consensus verification on the identification information of each first user and the corresponding proportion bill passes. Wherein the preset number is preset by a developer based on experimental measurement and calculation data.
In the embodiment of the present invention, a node of a block chain network may receive a proportion bill request submitted by a terminal device, where the proportion bill request carries proportion data of assets corresponding to a target bill by each first user included in a target user set. Further, the node generates a proportion bill for each first user included in the target user set based on the proportion data and the target bill, writes the identification information of each first user and the corresponding proportion bill into the block chain, and sends the proportion bill of each first user to the terminal device corresponding to each first user. And each subsequent first user can view the own occupation bill through the terminal equipment and declares own ownership of the asset based on the own occupation bill. Therefore, the ownership management of each first user for the assets is realized through the block chain, the opacity of the existing ownership management process is solved, and the accuracy and the reliability of ownership determination are improved.
Referring to fig. 4, which is a schematic flow chart of a data processing method based on a blockchain according to another embodiment of the present invention, the method according to an embodiment of the present invention may be executed by a node of a blockchain network, as shown in fig. 4, where the method includes:
s401: a node of the block chain network receives a proportion bill request submitted by a terminal device, wherein the proportion bill request carries proportion data of each first user, which is included in a target user set, aiming at assets corresponding to a target bill, the target bill is generated based on transaction information of the second user and each first user about the assets, and the proportion data comprises the proportion of each first user to the assets.
S402: the node generates a proportion ticket for each first user included in the set of target users based on the proportion data and the target tickets.
S403: and the node writes the identification information of each first user and the corresponding proportion bill into the block chain, and sends the proportion bill of each first user to the terminal equipment corresponding to each first user. For specific implementation of steps S401 to S403, refer to the related description of steps S301 to S303 in the above embodiments.
S404: the node receives a transfer application aiming at the target bill, the transfer application is provided when each first user and each third user included in the target user set trade aiming at the assets, and the transfer application carries a virtual resource transfer amount corresponding to the trade.
In one embodiment, after the second user performs asset transaction with each first user in the target user set, the second user may upload, through a terminal device, invoicing data related to the asset transaction to a node of a blockchain network, where the node may generate a target ticket for the asset based on the invoicing data, and write the target ticket into a blockchain. Further, when the asset is transferred and transferred from each first user in the target user set to a third user (that is, when each first user and the third user perform a transaction on the asset), any one of the first users may submit a transfer application for the target ticket to a node in the blockchain network through the terminal device, where the transfer application carries a virtual resource transfer amount corresponding to the transaction. The virtual resource transfer amount may be a transaction amount (e.g., 100 ten thousand yuan) related to the current transaction, or may be a virtual currency transfer amount (e.g., 10 bitcoins) related to the current transaction, and the like, which is not specifically limited in this embodiment of the present application.
In an embodiment, before any one of the first users in the target user set submits a transfer application for the target ticket to a node in the block chain network through a terminal device, the first users in the target user set need to perform data signature on the transfer application based on their own private keys, and the transfer application after data signature also carries the data signature of each first user. In this case, after receiving the transfer application for the target ticket, the node may further obtain the data signature of each first user from the transfer application, verify the data signature of each first user based on the own public key of each first user, and if the verification passes, execute the following step S405.
Illustratively, suppose that a first user included in the target user set is a user Zhang and a user Li respectively, the user Zhang and the user Li are ownership of an asset corresponding to the target instrument, and a third user is a user K, and a transaction occurs between the user Zhang and the user Li and the user K for the asset, and the asset is transferred from the user Zhang and the user Li to the user K. In this case, after the negotiation between the user bundle and the user bundle, any one of the user bundle and the user bundle can submit a transfer application for the target bill to a node in the block chain network through the terminal device, where the transfer application carries a virtual resource transfer amount corresponding to the transaction.
S405: and the node determines the transfer income of each first user according to the occupation ratio indicated by the occupation ratio bill of each first user and the virtual resource transfer amount. The transfer revenue may be the amount of revenue (e.g., 100 ten thousand dollars) or the amount of virtual currency (e.g., 7 bitcoins) obtained by each first user during the current asset transfer process, etc.
Illustratively, assuming that the virtual resource transfer amount is 100 ten thousand yuan, the target user set includes 2 first users, namely user zhang and user lie, and the duty ratio indicated by the duty ratio ticket of each first user is shown in table 2. In this case, the node may determine that the transfer income obtained by the user sheet in the asset transfer process is "100 ten thousand yuan by 70%" according to the occupation ratio "70%" indicated by the occupation ratio ticket of the user sheet and the virtual resource transfer amount "100 ten thousand yuan"; the node can determine that the transfer income obtained by the user plum in the asset transfer process is 100 ten thousand yuan by 30 percent to 30 ten thousand yuan according to the occupation ratio '30 percent' indicated by the occupation ratio bill of the user plum and the virtual resource transfer amount '100 ten thousand yuan'.
TABLE 2
| First user | Percentage ratio indicated by percentage ratio Ticket (%) |
| User sheet | 70 |
| User baggage | 30 |
S406: and the node transmits the virtual resource transfer amount and the transfer income of each first user to the terminal equipment corresponding to each first user.
In one embodiment, the first user also carries the device information of the terminal device corresponding to each first user in the target user set through the preemption bill request submitted by the terminal device, and the device information can be a terminal number; or the first user also carries account information (such as a social application account, a mailbox address and the like) corresponding to each first user in the target user set in the comparison bill request submitted by the first user through the terminal device. In this case, the node writes account information of each user or device information of the corresponding terminal device, and identification information of each first user and the corresponding proportion ticket into the blockchain when executing step S403.
Further, after determining the transfer revenue of each first user according to the occupation ratio and the virtual resource transfer amount indicated by the occupation ratio bill of each first user, the node may send the virtual resource transfer amount and the transfer revenue of each first user to the terminal device corresponding to each first user through account information of each user or device information of the corresponding terminal device, so that each first user can know the transfer revenue which should be obtained by the first user for the current transaction of the asset, and the virtual resource transfer amount corresponding to the current transaction may be reasonably distributed among the first users based on the transfer revenue corresponding to each first user.
In one embodiment, after the node sends the virtual resource transfer amount and the transfer income of each first user to the terminal device corresponding to each first user, each first user in the target user set is no longer an owner of the asset because the asset corresponding to the target data has been transferred, and therefore, for this case, the node may mark the proportion bill of each first user as a failure state. Further, in one embodiment, in addition to marking the status of each first user's proportion instrument as invalid, the node may also mark the reason for each first user's proportion instrument as invalid (e.g., a transfer of an asset occurred).
In one embodiment, the node acquires the asset account of each first user and the asset account of the third user, and the node transfers the virtual resource amount corresponding to the transfer income of each first user from the asset account of the third user to the asset account of each first user. The asset account may refer to a bank account (e.g., a bank card number), or may refer to a platform account corresponding to a service platform of the first user or the third account in the blockchain network.
Illustratively, assuming the above asset accounts are bank card numbers of the first user, the second user, and the third user, the first user in the target user set includes user Zhang and user Li, the bank card number of the user Zhang is XXXXXXXXXXX 01, the bank card number of the user Li is XXXXXXXXXXX 02, the bank card number of the third user is XXXXXXXXXXXXXXX 03, the transfer income of the user Zhang is 70 ten thousand yuan, and the transfer income of the user Li is 30 ten thousand yuan. In this case, the node may send a transfer request to a bank corresponding to the bank card of the third user requesting the bank to transfer 70 ten thousand dollars from the bank card xxxxxxxx03 of the third user to the bank card xxxxxxxxxx 01 of the third user and 30 ten thousand dollars from the bank card xxxxxxxxxx 03 of the third user to the bank card xxxxxxxx02 of the user's lie.
In the embodiment of the present invention, a node of a block chain network may receive a transfer application for a target ticket, where the transfer application is provided when each first user and a third user included in a target user set transact for an asset, and the transfer application carries a virtual resource transfer amount corresponding to the transaction. Further, the transfer revenue of each first user can be determined according to the proportion indicated by the proportion ticket of each first user and the virtual resource transfer amount, and the virtual resource transfer amount and the transfer revenue of each first user are sent to the terminal device corresponding to each first user.
