s341, a transaction party applies for the required transaction content to the transaction party, meanwhile, external matching and broadcasting are suspended, the transaction party uploads the transaction content through a personal node according to the requirements of the transaction party, an aggregation node checks whether the NFT authenticates or not, after the data of the transaction content is standardized through a self-adaptive universal data structure table, encryption algorithm processing is carried out to form a data ciphertext, and a hash value summary is obtained through a hash algorithm;
s342, the aggregation node sends brief introduction of transaction content data for a transaction party to check whether the transaction content data is needed or not, after confirming that the transaction content data is correct, the data ciphertext is uploaded to an intelligent contract, after processing, the intelligent contract is automatically uploaded to a sub-aggregation point and returns a hash value summary, the intelligent contract generates and issues a key and the hash value summary to the transaction party, meanwhile, an operation log is recorded to a personal terminal of a data contributor entity in the real physical world, and related information records such as stored information, summary, hash script and the like are subjected to trace processing;
s343, the aggregation node generates a data processing darkroom and a corresponding character string storage address, the other party of the transaction authorizes the transaction party, the intelligent contract is called after the digital identity of the transaction party is verified, the data or the data set is simulated, predicted and derived through a prediction algorithm, an optimal sample is obtained and transmitted to the data processing darkroom, the transaction party is informed of sharing the data storage address, after the sharing condition is met, the transaction party acquires a secret key, passes the verification and triggers the intelligent contract, meanwhile, the relevant data attribute of the personal terminal of the participant is updated, and marks are reserved again;
s344, the transaction party respectively unlocks the data processing secret room and the data result ciphertext by using the key string to obtain shared scientific transaction content, the shared transaction flow feeds back the data processing result monitored by the other party of the consensus transaction, and the transaction party leaves the shared result script.
9. The method for constructing a guest group ecological scene based on metauniverse virtual reality technology according to claim 8, wherein the transaction contents include goods, money, services, intellectual property, services, etc. capable of being transacted, assets or services.
10. A guest group ecological scene construction system based on a meta-universe virtual reality technology, comprising:
virtual scene generation module: the method comprises the steps of obtaining basic data provided by a user, wherein the basic data comprise basic map geometric topography files and setting parameters, and generating a meta-universe virtual scene based on the basic data;
the virtual character creation module is used for creating a virtual character;
virtual scene optimization module: monitoring the metauniverse virtual scene by using a metauniverse optimization model, and optimizing the metauniverse virtual scene when disturbance abnormality occurs in a monitoring result;
a transaction module: and configuring at least one aggregation node and a plurality of common nodes for the metauniverse virtual scene, and realizing exchange of transaction contents by using the common nodes and the aggregation nodes by the transaction parties.
