Network security is guaranteed across three areas: An unmanipulable and unpredictable node selection process for temporal xx node teams: We randomly select nodes for mixing, endorser, and block producer teams, making it almost impossible for malicious nodes to seize control of these teams. New quantum-secure signatures: The new compact, quantum-secure endorser group signatures used by xx network make it impossible for malicious nodes to control these signatures by breaking xx network’s hash-based quantum secure crypto. Node staking: node operators are highly motivated to fulfill their roles. They can stake their nodes, earn block rewards, or lose rewards in case of poor performance, which encourages efficient work in the network.
