Hydra.Party

Description

Types and functions revolving around a Hydra Party. That is, a participant in a Hydra Head, which signs transactions or snapshots in the Hydra protocol.

Synopsis

newtype Party = Party {
- vkey :: VerificationKey HydraKey
}
deriveParty :: SigningKey HydraKey -> Party
partyToChain :: Party -> Party
partyFromChain :: MonadFail m => Party -> m Party
class HasParty a where
- getParty :: a -> Party

Documentation

newtype Party Source #

deriveParty :: SigningKey HydraKey -> Party Source #

Get the Party given some Hydra SigningKey.

partyToChain :: Party -> Party Source #

Convert "high-level" Party to the "low-level" representation as used on-chain. See Party for an explanation why this is a distinct type.

partyFromChain :: MonadFail m => Party -> m Party Source #

Retrieve the "high-level" 'Party from the "low-level" on-chain representation. This can fail because of the lower type-safety used on-chain and a non-guaranteed verification key length. See Party for an explanation why this is a distinct type.

class HasParty a where Source #

Type class to retrieve the Party from some type.
