How to run a Validator node

System Requirements

CPU:  minimum 4core, recommend 8core +
RAM:  minimum 16GB, recommend 32GB +
DISK : minimum SSD 2.5TB, recommend SSD 3TB +
Network: minimum 1Gbps, recommend 2Gbps +

External Communications
TCP 7100: TCP port used for peer-to-peer connection between peer nodes.
TCP 9000: JSON-RPC or RESTful API port serving application requests.P-Rep must allow TCP connections to port 7100 and 9000 of an external host. ( Use 0.0.0.0/0 for a source from any network )
