The Green Chains are built to be a community of interconnected  individual ledgers through a network, but it can also be used in offline mode for applications that do not require constant interaction with other nodes, provided that it happens for a brief period. This is very useful for low-powered devices, like the ones used in IoT environments.  Devices implementing the GreenChains standard may generate new records while remaining disconnected if their purpose is not to interact directly with other instances. Such devices must be connected to the network only to publish their records and get interlocks from other instances. After that is done, they can go back offline. Until published and mirrored, though, offline records are not considered part of the InterlockLedger network.
