For example, a certain experimental institution a obtains experimental data through experiments, if the experimental data needs to be sold by a, the experimental data is to-be-transacted data, at this time, a is a producer and an owner of the to-be-transacted data, if the to-be-transacted data is sold by a to B, at this time, B is a purchaser of the to-be-transacted data, after the transaction is completed, a transaction amount paid by B is obtained, and the transaction amount is revenue generated by the transaction, the revenue generated by the transaction is respectively allocated to accounts corresponding to the producer of the to-be-transacted data and the owner of the to-be-transacted data according to the right and interest allocation rule, and at this time, a is both the producer of the to-be-transacted data and the owner of the to-be-transacted data, so that all the revenue generated by the transaction is allocated to the account of a.
Further, after the experimental data are sold to the data storage device B, the data storage device A is a producer of the experimental data, and the data storage device B is an owner of the experimental data; and if the experimental data needs to be sold by the B, the experimental data is to-be-traded data, if the C wants to purchase the experimental data, the C is a purchaser of the to-be-traded data, after the transaction is completed, the transaction amount paid by the C is obtained, the transaction amount is income generated by the transaction, the income generated by the transaction is respectively distributed to a producer of the to-be-traded data and an owner of the to-be-traded data according to the right and interest distribution proportion rule, and the income generated by the transaction is respectively distributed to accounts corresponding to the A and the B according to the right and interest distribution proportion.
It should be noted that the equity proportion rule in the embodiment of the present application may indicate that the equity distribution proportion corresponding to each equity relevant party is fixed, or may be changed according to a preset rule, which is not limited herein.
In the prior art, data to be traded is directly traded in a point-to-point mode, if the data is traded for multiple times, the owner of the data to be traded is probably not the originator of the data, under the condition, when the owner of the data to be traded trades the data again, the legal benefit of the originator is difficult to guarantee, and the rights and interests of other rights and interests relevant parties cannot be determined in the trading process, so in the implementation process, the benefits generated by the data to be traded are respectively distributed to accounts corresponding to each rights and interests relevant party according to the rights and interests distribution example rule in the second intelligent contract, and the legal rights and interests of each rights and interests relevant party are effectively ensured.
Illustratively, capturing revenue generated by the transaction may be accomplished by any one or a combination of the following:
the method I comprises the following steps: when a purchaser of data to be traded determines a trading order, the blockchain data trading platform acquires corresponding payment amount from an account of the purchaser, the payment amount is income generated by trading, the income generated by the trading is stored in the blockchain data trading platform, and the saved income generated by the trading is called when the blockchain data trading platform executes rights and interests distribution.
In the implementation process, the income generated by the transaction is stored in the blockchain data transaction platform in advance, so that the blockchain data transaction platform can conveniently execute rights and interests distribution according to the second intelligent contract.
The second method comprises the following steps: when a purchaser of data to be traded determines a trading order and pays money to the blockchain data trading platform, the blockchain data trading platform obtains income generated by trading, and further, the blockchain data trading platform executes rights and interests allocation.
In the implementation process, the income generated by the transaction is acquired according to the payment operation of the buyer, and the safety of the payment amount of the buyer can be effectively ensured.
As another example, the second intelligent contract further includes transaction times of the current data to be transacted and corresponding allocation proportions of the rights and the interests, and the allocation proportions of the rights and the interests corresponding to the different transaction times of the data to be transacted are different.
For example, if the current transaction frequency of the data to be transacted is 5 th time, the corresponding rights and interests allocation proportion of a producer of the data to be transacted and an owner of the data to be transacted is 3: 7; if the current transaction frequency of the data to be transacted is 6 th time, the corresponding rights and interests allocation proportion 2:8 of the producer of the data to be transacted and the owner of the data to be transacted are respectively corresponding currently.
It should be noted that, in the embodiment of the present application, only the determination of the right and gain allocation ratio by the number of transactions is taken as an example for description, and in an actual application process, the right and gain allocation ratio may also be determined according to a transaction time period, where the transaction time period is different, the corresponding right and gain allocation ratio is different, or other determination manners may also be used, and no limitation is made herein.
As another embodiment, the second intelligent contract may further include that the data to be traded is respectively in the right and benefit valid period of each right and benefit related party, and the profit generated by the trade is respectively distributed to the account corresponding to each right and benefit related party according to the right and benefit distribution ratio, and may further include:
and judging whether the current transaction time is within the right and interest valid period corresponding to each right and interest related party, if so, distributing the income generated by the transaction to the account corresponding to the corresponding right and interest related party according to the right and interest distribution proportion, and if not, not distributing the income generated by the transaction to the right and interest related party exceeding the right and interest valid period.
For example, whether the current transaction time is within the right and interest validity period corresponding to the producer of the data to be transacted and the owner of the data to be transacted is judged, if the current transaction time is within the right and interest period of the producer of the data to be transacted, the income generated by the transaction is distributed to the producer of the data to be transacted according to the right and interest distribution proportion, if the current transaction time exceeds the right and interest period of the producer of the data to be transacted, the income generated by the transaction is not distributed to the owner of the data to be transacted according to the right and interest distribution proportion, if the current transaction time exceeds the right and interest period of the owner of the data to be transacted, the income generated by the transaction is not distributed to the owner of the data to be transacted.
In the implementation process, the right validity period is set in the second contract, and the right time of the relevant party can be reasonably controlled, so that the controllability of the right of the data to be traded is improved.
In some embodiments, after allocating the revenue generated by the transaction to the account corresponding to each equity relevant party according to the equity allocation proportion, the method further includes: and generating updating information of the intelligent contract, wherein the updating information is used for updating the intelligent contract.
Illustratively, after allocating the revenue generated by the transaction to the accounts corresponding to the producer of the data to be traded and the owner of the data to be traded respectively according to the allocation proportion of the rights and the interests, generating the update information of the intelligent contract, sending the update information to the owner of the data to be traded, and further updating the intelligent contract according to the update information by the owner of the data to be traded.
In the implementation process, after the income generated by the transaction is respectively distributed to the accounts corresponding to the producer of the data to be transacted and the owner of the data to be transacted according to the right and interest distribution proportion, the updating information of the intelligent contract is generated and sent to the owner of the data to be transacted, so that the owner of the data to be transacted can update the intelligent contract according to the updating information.
