type NumSoftwareVersion = Word32 Source #
Numeric software version associated with
ApplicationName
checkSoftwareVersion :: MonadError SoftwareVersionError m => SoftwareVersion -> m () Source #
A software version is valid iff its application name is valid
data SoftforkRule Source #
Values defining softfork resolution rule
If a proposal is confirmed at the
s
-th epoch, softfork resolution
threshold at the
t
-th epoch will be 'max spMinThd (spInitThd - (t - s) *
spThdDecrement)'.
Softfork resolution threshold is the portion of total stake such that if total stake of issuers of blocks with some block version is greater than this portion, this block version becomes adopted.

upAdptThd :: Word8 -> ProtocolParameters -> Int Source #
In Byron we do not have a
upAdptThd
protocol parameter, so we have to
use the existing ones.
lovelacePortionToRational . srMinThd . ppSoftforkRule
will give us the
ratio (in the interval
[0, 1]
) of the total stake that has to endorse a
protocol version to become adopted. In genesis configuration, this ratio
will evaluate to
0.6
, so if we have 7 genesis keys,
upAdptThd = 4
.
isBootstrapEraPP :: ProtocolParameters -> EpochNumber -> Bool Source #
Version of
isBootstrapEra
which takes
ProtocolParameters
instead of
unlock stake epoch
