Firstly, blockchain adopts a decentralized network architecture, where transaction data is synchronized and stored on all nodes in the system, ensuring data consistency and security. Secondly, consensus mechanisms in blockchain technology (such as proof of work, proof of stake, etc.) are used to validate transactions and determine the effectiveness of data, thereby guaranteeing the accuracy and credibility of real-time transaction data.↵↵In addition, blockchain technology can also be combined with other real-time data processing technologies (such as the Internet  of Things, big data analysis, etc.) to further optimize the query of real-time transaction data. For example, through smart contracts and distributed application platforms, blockchain can provide efficient and reliable data storage and transaction processing capabilities, which are essential for real-time data analysis and decision-making."}]}],"pr":"850c3d0cb70cda8cd5e1fe688de9967661ce1862f69c18fc5bc5426a63e41e32"}
