 Operates a single peer node instance of the AIN blockchain. A single blockchain node instance processes incoming transaction requests and maintains a local copy of the entire blockchain. The blockchain node first queries the tracker-server for ip addresses of other peers, and then syncs its local blockchain to the network consensus blockchain. If a node is included in the whitelist and has staked appropriate amount of AIN, it will then take part in the consensus protocol.
