The xDai network functions as a virtual public utility, with its security maintained by validators and delegators who utilize the xDai token. Participants can contribute to chain consensus by staking their xDai, which helps secure the network and yields rewards.
Connectivity to the Ethereum mainnet is established through two bridges that enable smooth two-way asset transfers. Transaction tokens are moved from the mainnet to the xDai sidechain via the DAI-xDai bridge, while the OmniBridge handles other cross-chain transfers.
xDai operates on the public POSDAO consensus mechanism, which is based on delegated proof-of-stake. Any individual possessing sufficient STAKE to operate a node is eligible to become a validator. Delegators influence this process by assigning their STAKE to specific candidates they wish to see appointed as validators.
