A CopyrightChain validator is responsible for verifying transactions on the CopyrightChains. Once transactions are verified, they are added to the ledger. In proof of stake systems like CopyrightChains, validators are given re- wards as long as they stake the network’s token (i.e. NIMs Utility Token). This consensus mechanism also helps secure the network.
A Copyrightchain, or a subnetwork, is a dynamic set of validators (aka computer servers) working together to achieve consensus on the state of a set of blockchains. Each blockchain is validated by exactly one subnet. A subnet can validate many blockchains. A node may be a member of many subnets.
A subnet manages its own membership, and it may require that its constituent validators have certain properties.
