Purchasing public partial meta-universe assets and switching private partial meta-universe scenes according to the middle-order user rights to obtain middle-order user functions;
the method comprises the steps of purchasing public part meta-universe assets and switching discounts on private part meta-universe scenes according to high-order user rights to obtain high-order user functions;
dividing the public part universe into purchased resources and unpopulated resources according to the purchased resources of the user;
the method comprises the steps that selling processing is carried out according to purchased resources of a user, the purchased resources of the user are marked as unpopulated resources, and virtual currency data are obtained;
extracting history change record information of the non-purchased resources to generate history change information;
carrying out quantization processing on the history change information to obtain resource quantization data;
and predicting the tendency of the value of the unpopulated resource in the quantized data of the resource by using a meta space market price fluctuation emotion calculation formula, and generating the value of the unpopulated resource to construct a transaction rule link.
7. The blockchain network-based metauniverse access method of claim 6, wherein the metauniverse user asset class formula is as follows:
where K is denoted as metauniverse user asset class, w is denoted as balance data of virtual currency data, Weight information expressed as resources purchased by the user, a expressed as total amount data of virtual currency data, t expressed as the existence time of a trusted virtual user, and ω expressed as an abnormal adjustment item of the asset class of the metauniverse user.
8. The method for accessing a metauniverse based on a blockchain network as claimed in claim 6, wherein the metauniverse market price fluctuation emotion calculation formula is as follows:
wherein Q is expressed as a metauniverse market price fluctuation emotion index, N is expressed as metauniverse market historical trading days, and x i Expressed as the average daily cost of the non-purchased resources,historical average price of the purchase, θ is weight information of market emotion value, +.>Expressed as the average price of the day for the unpopulated resource, ω is expressed as an adjustment term for the metauniverse market price fluctuation emotion abnormality index.
9. The blockchain network-based meta-universe access method of claim 6, wherein step S5 includes the steps of:
step S51: data encryption is carried out on the virtual currency data and the transaction data by utilizing the homomorphic encryption public key, and a transaction ciphertext is generated;
step S52: when the virtual currency data and the transaction data are changed, corresponding data change is carried out on the transaction encryption data, and a transaction result ciphertext is generated;
Step S53: carrying out block storage processing on the transaction result ciphertext, thereby generating an encrypted storage file;
step S54: when the virtual currency data and the transaction data are called, the encrypted storage file is decrypted by using the homomorphic encrypted private key, so that the meta-universe access operation is realized.
10. A blockchain network device, comprising:
at least one processor; the method comprises the steps of,
a memory communicatively coupled to the at least one processor; wherein,
the memory stores a computer program executable by the at least one processor to enable the at least one processor to perform the blockchain network-based meta-universe access method of any one of claims 1 to 9.
