When a node or system fails, fault tolerance settings can help transfer tasks  and data to other nodes that are operating normally, thereby ensuring the stability and continuous operation of the blockchain network. This setup can include technologies such as consensus algorithms, smart contracts, and cross-chain communication, which help reduce the risk of single-point failures and enhance the fault tolerance of the entire blockchain system."}]}],"pr":"f16bd985b146adcd8b3259cb241f15fb3d337c060ce27338f6744bb35864f56a"}
