data HardForkSpec Source #

This data structure is used to specify if and when hardforks should take place, and the version used at each era. See stayInByron and hardForkInto for examples.

ProtocolInfo elaboration

mkSimpleTestProtocolInfo Source #

Arguments

∷ ∀ c. (CardanoHardForkConstraints c, c ~ StandardCrypto)
⇒ DecentralizationParam	Network decentralization parameter.
→ SecurityParam
→ ByronSlotLengthInSeconds
→ ShelleySlotLengthInSeconds
→ ProtVer
→ HardForkSpec
→ ProtocolInfo (CardanoBlock c)

Create a Cardano protocol info for testing purposes, using some predifined settings (see below). For a more general version see mkTestProtocolInfo.

The resulting ProtocolInfo will use a randomly generated core node. This generation will use a fixed seed. See mkTestProtocolInfo for a function that takes a core node as parameter.

The resulting ProtocolInfo will:

Use a NeutralNonce.
Use a fixed number of slots per KES evolution.
Have version 0 0 0 as Byron protocol version.
Use 1 as PbftSignatureThreshold

If you want to tweak the resulting protocol info further see mkTestProtocolInfo.

The resulting ProtocolInfo contains a ledger state. The HardForkSpec parameter will determine to which era this ledger state belongs. See HardForkSpec for more details on how to specify a value of this type.

mkTestProtocolInfo Source #

Arguments

∷ ∀ m c. (CardanoHardForkConstraints c, IOLike m, c ~ StandardCrypto)
⇒ (CoreNodeId, CoreNode c)	Id of the node for which the protocol info will be elaborated.
→ ShelleyGenesis c	These nodes will be part of the initial delegation mapping, and funds will be allocated to these nodes.
→ ProtocolVersion	Protocol version of the Byron era proposal.
→ Nonce
→ Config
→ GeneratedSecrets
→ Maybe PBftSignatureThreshold
→ ProtVer	See `protocolInfoCardano` for the details of what is the relation between this version and any `TriggerHardForkAtVersion` that might appear in the `HardForkSpec` parameter.
→ HardForkSpec	Specification of the era to which the initial state should hard-fork to.
→ (ProtocolInfo (CardanoBlock c), m [BlockForging m (CardanoBlock c)])
