# Network Topology

Nodes form a flat P2P mesh: each X1Node connects to peers (over Internet or the mobile channel) and broadcasts new blocks. The network has no special supernodes – every full node is equal. Data (the blockchain state, ledger, smart contracts) is fully replicated and sharded across nodes, eliminating any central hub or single point of failure . This contrasts with traditional systems that use centralized servers; here every user’s device helps secure the network. The protocol includes built-in security for node communication, leveraging each node’s unique authenticator and secure channels.
