The main limitations include: 1. Technical challenges, such as scalability and energy efficiency issues; 2. High throughput, resulting in limited processing speed; 3. Existing latency time, unable to meet the needs of high-frequency trading; 4. Whether the capacity and bandwidth are sufficient, which cannot yet meet the large-scale data storage and transmission requirements; 5. Ensuring security, facing risks of hacker attacks and cybersecurity; 6. Causing resource waste, such  as energy consumption and hardware resource waste; 7. Government regulation."}]}],"pr":"6084379ccce2eaf50df58cd9552ef7f6c68b8c14961cf1a823f3302dcedd4a34"}
