The ParamsForNet function was removed, so likewise this change removes
ErrUnknownNet error that it used to return.
As network registration is now necessary for correct handling of
alternate network encoding magics, and therefore the ErrDuplicateNet
error returned by Register is here to stay, kill the comment about the
error being removed later.
This commit adds more chain-related fields to the parameters as a part of
converting btcchain to work with btcnet parameters instead of coding the
network-specific knowledge into the package itself.
It also moves the checkpoints from btcchain since checkpoints are a
network parameter and make more sense here.
ok @jrick
This change adds two parameters to the Params struct which are used by
btcd to alter behavior based on the active network, rather than
hardcoding checks for a particular network.
The first, ResetMinDifficulty, specifies whether the target difficulty
can change between the retarget intervals.
The second, RelayNonStdTxs, specifies whether standard transaction
checks should not be performed when accepting mempool transactions.
The zero values (false) for both of these bools are the correct
parameter values for mainnet.
While here, rename the test network version 3 to "testnet3", as both
btcd and btcwallet will include additional handling to rename this to
"testnet" for directory names, and a switch to "testnet3" is planned
in the future.
