In the blockchain network, participants (nodes) communicate with each other and collaborate to record and store transaction records and information on multiple nodes, rather than concentrating on a central server. This distributed network  structure gives blockchain higher resistance to attacks and fault tolerance. Even if some nodes are attacked or fail, other nodes can still operate smoothly to ensure the normal operation of the system."}]}],"pr":"dd07f20f61cee3409164e96704cd8da07a043ebcb73eeb2f4078dcbe82d5913b"}
