sealed abstract class ChainParams extends AnyRef
Created by chris on 5/22/16. ChainParams 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.

Abstract Value Members
- abstract def allowMinDifficultyBlocks: Boolean
Whether we should allow minimum difficulty blocks or not As an example you can trivially mine blocks on RegTestNetChainParams and TestNetChainParams but not the MainNetChainParams
- abstract def base58Prefixes: Map[Base58Type, ByteVector]
The mapping from a Base58Typeto a String.
The mapping from a Base58Typeto a String. Base58 prefixes for various keys/hashes on the network.
