In practical application, based on the traditional digital asset right-determining trading platform based on blockchain, an asset and right-evidence integrated trading platform is innovatively provided. Each participating node of the blockchain can access the blockchain network to serve as a user of the blockchain, and can also serve as an authentication node to authenticate, decrypt and the like when offline.
First, digital assets are divided into three types, an unacknowledged asset, an ownership-granted asset, a usage-granted asset. The correlation is shown in fig. 3, and after the ownership right is confirmed, the digital assets with the un-confirmed rights are encrypted by using the public key of the ownership person. In conducting digital asset usage transactions, the digital asset usage purchaser will obtain a determined right to encrypt and bind its corresponding usage ticket using its own public key by means of an intelligent contract, all of which are unique to different digital asset users.
Unlike traditional blockchain digital assets, the system designed in the method can realize ownership free transaction and use free transaction of the digital assets. The owner of the digital asset is able to conduct two types of transactions, ownership transactions, usage transactions, respectively. And the rights holder of the digital asset is able to conduct transactions of the rights, as described in more detail below.
Ownership transaction:
the owner of the digital asset is able to transfer ownership of the digital asset and the original owner no longer enjoys ownership of the asset after transfer. The transaction flow is achieved in an intelligent contract form in a similar manner to the conventional blockchain digital asset transaction manner, and therefore, the detailed description is omitted.
Usage right transaction:
the right-of-use transactions are classified into two types, namely, transactions in which owners participate, and transactions in which non-owners participate. The transaction flow is shown in fig. 4 and 5, respectively. In particular, in transactions involving non-owners, transfer of assets is only achieved using rights-in-process assets, and in the process of transactions, transfer of assets is ensured by destroying original rights-in-process assets.
In this embodiment, a digital asset right and transaction method, device, equipment and storage medium are provided, the method includes performing ownership right on a target digital asset; when a second user node initiates a digital asset transaction with a first user node, judging transaction content of the digital asset transaction; if the transaction content is ownership, carrying out ownership transaction action on the target digital asset; and if the transaction content is the use right, carrying out use right confirmation on the target digital asset, and carrying out use right transaction action on the target digital asset. The invention can realize the ownership free transaction and the use free transaction of the digital asset by dividing the digital asset into the un-authorized asset, the ownership authorized asset and the use authorized asset. The owner of the digital asset is able to conduct two types of transactions, ownership transactions, usage transactions, respectively. And the rights holder of the digital asset can conduct transactions of the rights.
