The updatable protocol parameters

data ProtocolParameters Source #

Deprecated: Use the ledger's PParams (from module Cardano.Api.Ledger) type instead of ProtocolParameters. The type will be removed after Chang hard fork.

The values of the set of updatable protocol parameters. At any particular point on the chain there is a current set of parameters in use.

These parameters can be updated (at epoch boundaries) via an UpdateProposal, which contains a ProtocolParametersUpdate.

The ProtocolParametersUpdate is essentially a diff for the ProtocolParameters.

There are also parameters fixed in the Genesis file. See GenesisParameters.

ProtocolParameters

Deprecated: Use the ledger's PParams (from module Cardano.Api.Ledger) type instead of ProtocolParameters. The type will be removed after Chang hard fork.

Fields

protocolParamProtocolVersion :: (Natural, Natural)
Protocol version, major and minor. Updating the major version is used to trigger hard forks. (Major , Minor )
protocolParamDecentralization :: Maybe Rational
The decentralization parameter. This is fraction of slots that belong to the BFT overlay schedule, rather than the Praos schedule. So 1 means fully centralised, while 0 means fully decentralised.
This is the "d" parameter from the design document.
Deprecated in Babbage
protocolParamExtraPraosEntropy :: Maybe PraosNonce
Extra entropy for the Praos per-epoch nonce.
This can be used to add extra entropy during the decentralisation process. If the extra entropy can be demonstrated to be generated randomly then this method can be used to show that the initial federated operators did not subtly bias the initial schedule so that they retain undue influence after decentralisation.
protocolParamMaxBlockHeaderSize :: Natural
The maximum permitted size of a block header.
This must be at least as big as the largest legitimate block headers but should not be too much larger, to help prevent DoS attacks.
Caution: setting this to be smaller than legitimate block headers is a sure way to brick the system!
protocolParamMaxBlockBodySize :: Natural
The maximum permitted size of the block body (that is, the block payload, without the block header).
This should be picked with the Praos network delta security parameter in mind. Making this too large can severely weaken the Praos consensus properties.
Caution: setting this to be smaller than a transaction that can change the protocol parameters is a sure way to brick the system!
protocolParamMaxTxSize :: Natural
The maximum permitted size of a transaction.
Typically this should not be too high a fraction of the block size, otherwise wastage from block fragmentation becomes a problem, and the current implementation does not use any sophisticated box packing algorithm.
protocolParamTxFeeFixed :: Coin
The constant factor for the minimum fee calculation.
protocolParamTxFeePerByte :: Coin
Per byte linear factor for the minimum fee calculation.
protocolParamMinUTxOValue :: Maybe Coin
The minimum permitted value for new UTxO entries, ie for transaction outputs.
protocolParamStakeAddressDeposit :: Coin
The deposit required to register a stake address.
protocolParamStakePoolDeposit :: Coin
The deposit required to register a stake pool.
protocolParamMinPoolCost :: Coin
The minimum value that stake pools are permitted to declare for their cost parameter.
protocolParamPoolRetireMaxEpoch :: EpochInterval
The maximum number of epochs into the future that stake pools are permitted to schedule a retirement.
protocolParamStakePoolTargetNum :: Natural
The equilibrium target number of stake pools.
This is the "k" incentives parameter from the design document.
protocolParamPoolPledgeInfluence :: Rational
The influence of the pledge in stake pool rewards.
This is the "a_0" incentives parameter from the design document.
protocolParamMonetaryExpansion :: Rational
The monetary expansion rate. This determines the fraction of the reserves that are added to the fee pot each epoch.
This is the "rho" incentives parameter from the design document.
protocolParamTreasuryCut :: Rational
The fraction of the fee pot each epoch that goes to the treasury.
This is the "tau" incentives parameter from the design document.
protocolParamCostModels :: Map AnyPlutusScriptVersion CostModel
Cost models for script languages that use them.
Introduced in Alonzo
protocolParamPrices :: Maybe ExecutionUnitPrices
Price of execution units for script languages that use them.
Introduced in Alonzo
protocolParamMaxTxExUnits :: Maybe ExecutionUnits
Max total script execution resources units allowed per tx
Introduced in Alonzo
protocolParamMaxBlockExUnits :: Maybe ExecutionUnits
Max total script execution resources units allowed per block
Introduced in Alonzo
protocolParamMaxValueSize :: Maybe Natural
Max size of a Value in a tx output.
Introduced in Alonzo
protocolParamCollateralPercent :: Maybe Natural
The percentage of the script contribution to the txfee that must be provided as collateral inputs when including Plutus scripts.
Introduced in Alonzo
protocolParamMaxCollateralInputs :: Maybe Natural
The maximum number of collateral inputs allowed in a transaction.
Introduced in Alonzo
protocolParamUTxOCostPerByte :: Maybe Coin
Cost in ada per byte of UTxO storage.
Introduced in Babbage
