DIGITAL CERTIFICATE MANAGEMENT METHOD AND APPARATUS, COMPUTER DEVICE, AND STORAGE MEDIUM

Resumen de: EP4773544A1

0001 Embodiments of this application disclose a digital certificate management method and apparatus, a computer device, and a storage medium, and belong to the field of network security technologies. In this application, a BCF node may send certificate information of a first NF node to a plurality of target CA nodes in different network domains in a blockchain system based on CA node indication information in a certificate issuance request of the first NF node, the plurality of target CA nodes jointly provide certificate signatures for the certificate information of the first NF node, and then the BCF node sends an authorized digital certificate to the first NF node based on the signatures, thereby implementing decentralized cross-domain certificate issuance.

PLATFORM AND METHOD FOR GENERATING CONSECUTIVE TIME-BASED SNAPSHOTS REPRESENTATIVE OF TRANSACTIONS PERFORMED ON DIGITAL TOKEN POOLS MANAGED BY A BLOCKCHAIN

Resumen de: US2024086912A1

Platform and method for collecting and analyzing transactions performed on digital token pools managed by a blockchain. The platform collects transaction data related to transactions performed on the digital token pools managed by the blockchain. The transaction data related to each transaction are collected from N geographically distributed nodes belonging to the blockchain, the transaction data being stored in data blocks at the N nodes. A validation algorithm is used to determine validated transaction data based on the collected transaction data, comprising comparing for each transaction the transaction data collected from the N nodes and determining the validated transaction data for the transaction based at least on a result of the comparison. The validated transaction data are processed to calculate a value of at least one metric based on the validated transaction data. The transaction data may be related to transactions performed on digital token pools managed by several blockchains.

Resumen de: WO2026142154A1

The present invention provides a blockchain-based competitive random number generation method and a system for performing same, wherein: an encryption module, having received user input seeds from first and second user terminals, respectively, generates first hash values, generates second hash values on the basis of the respective first hash values, and transmits the generated first and second hash values to each of the first and second user terminals; and a blockchain system receives and stores the second hash values transmitted from the first and second user terminals, verifies the first hash values transmitted from the first and second user terminals, and, when all verifications of the first hash values received from the first and second user terminals are successful, generates a random number on the basis of the first hash values transmitted from the first user terminal and the second user terminal, and transmits the generated random number to at least one of the first and second user terminals.
