Network.Polkadot.Extrinsic.Era

An era to describe the longevity of a transaction.

Documentation

data Era

The era for an extrinsic, indicating either a mortal or immortal extrinsic.

Constructors

ImmortalEra

The ImmortalEra for an extrinsic.

MortalEra !Word32 !Word32

The MortalEra for an extrinsic, indicating period and phase.

Period and phase are encoded: - The period of validity from the block hash found in the signing material. - The phase in the period that this transaction's lifetime begins (and, importantly, implies which block hash is included in the signature material). If the period is greater than 1 << 12, then it will be a factor of the times greater than 1 << 12 that period is.
