Through its decentralized design, blockchain stores data on multiple nodes rather than focusing on a central server. This distributed data storage reduces the risk of single-point failure and improves the stability and availability of the system. Meanwhile, blockchain employs consensus algorithms to ensure data consistency between nodes, further enhancing the system's reliability. However, there are still some limitations to blockchain technology, such as performance degradation due to increased node numbers and the potential risk of local failures in partially decentralized  designs. Therefore, in practical applications, the degree of decentralization of blockchain needs to be comprehensively considered."}]}],"pr":"8b08e0fe103a61731757f6809b52332f7062eed73118399ee1b2ef21f7cacb46"}
