Detailed Description

CChainParams defines various tweakable parameters of a given instance of the Bitcoin system.

There are three: the main network on which people trade goods and services, the public test network which gets reset from time to time and a regression test mode which is intended for private networks only. It has minimal difficulty to ensure that blocks can be found instantly.
