Distributed storage technology enables the blockchain system to achieve distributed recording and storage of data information, ensuring the security and efficient access to data. Decentralized storage reduces the impact of single-node failures on the entire system by storing data on multiple nodes in the network, thereby improving system stability and reliability. Edge storage technology stores data  on edge nodes closer to users, reducing data transmission latency and improving the user experience. These storage technologies together form the foundation of the blockchain system, providing support for decentralized, secure, and reliable blockchain applications."}]}],"pr":"6b1993ebe71ecbfc714dee1c7d0ca2273d7102de70ca01626338960f5031c9ef"}
