  • Publication number: 20240354878
    Abstract: The present disclosure discloses a method and an apparatus for data verification, and relates to the field of computer technology. A implementation of the method includes: performing a first verification on data-to-be-verified, where the data-to-be-verified includes a first contract parameter, a identifier of the smart contract, and a first execution result; processing, after the first verification is passed, the first contract parameter to obtain second contract parameter, and executing a smart contract based on the second contract parameter to obtain a second execution result; and sending the second contract parameter, the identifier of the smart contract, and the second execution result to a consensus verification node for a consensus verification.

  • Patent number: 12086107
    Abstract: A file sharing method, apparatus, and system, mainly relate to the technical field of computers. The method comprises: obtaining a file to be shared; concurrently transmitting the shared file compression packages onto a blockchain; forming data blocks according to a compressed package file name and a hash value thereof, wherein the data blocks comprise the hash value of a previous data block; using the hash value of a last data block as a root hash value; and according to the root hash value, obtaining a file comprised in the last data block, and then obtaining each file compression package in a blockchain indicated by the root hash value.

  • Publication number: 20240281802
    Abstract: The present disclosure relates to a digital currency-based payment method, platform and system, and a terminal, and relates to the technical field of computers. An implementation of the method includes: receiving a target payment request for a first digital currency in a frozen state, the first digital currency in the frozen state being generated based on a pre-payment request and a pre-configured pre-payment deposit smart contract; generating a second digital currency according to a target payment amount indicated by the target payment request, the first digital currency, and a pre-configured pre-payment verification smart contract; and sending the second digital currency to a first account corresponding to the first digital currency. The implementation improves the transaction security, and is conducive to protecting the rights and interests of a user.

  • Publication number: 20240146509
    Abstract: Provided are a method and apparatus for generating a random number in a blockchain, wherein the method includes: a first random number and a first digest value of the first random number are locally generated by a first node in a blockchain; the first node submits the first digest value to a smart contract; the smart contract broadcasts a first service; the smart contract determines a second node from the at least one blockchain node; when the first service ends, the first node submits the first random number to the smart contract; when the smart contract verifies that the first random number corresponds to the first digest value, the smart contract generates a second random number based on a second digest value of the second node and the first random number; and a second service is started based on the second random number.
