# Guardian Chain

### Guardian Chain

The Guardian chain is an L1 blockchain that acts as a security coordination layer, enabling other sovereign L1s to leverage the economic security of restaked ETH. The nodes in the Guardian chain are a set of ‘Guardians’ who leverage the restaked ETH allocated to them by the Ethos operators, to extend security to other chains and provide further services.
