By necessity, the Nexus mobile wallet will only store and process block headers and the user's signature chain, starting with the hash of the very first Tritium block hard-coded into the wallet. For an advanced user running their own full node and certain API functionality, it is possible to enable the mobile wallet to establish a direct connection. This enables a user to offload heavy computational work to their desktop node, such as searching through historical data or maintaining a full copy of the blockchain.
