 This design allows Omni to manage DDoS attacks, provide "gas liquidity" for seamless transactions across rollups, and progressively decentralize governance. This approach ensures backward compatibility with local gas tokens through an abstracted gas marketplace, highlighting the native token's role in enhancing the network's functionality and security.

 ## Restaking ETH
 
-The Omni Network consists of validators who restake **\$ETH** and monitor the state of rollups. These validators relay state updates from one domain to others and provide crypto-economic assurance of validity.

 This means that the Omni Network is going to be the first platform that provides developers with a global view of state from all rollups, making cross-rollup application development extremely simple. All of this is made possible through the unique insight to use Ethereum's validator set to aggregate a global perspective of Ethereum's L2 ecosystem.

 - **Omni Staking Contract**: Implemented on the Omni EVM, this contract tracks each validator’s stake and delegations, distributes rewards, and manages slashing events.
