newtype NatNonce Source #

We provide our own nonces to mkBlock, which we then wish to recover as the output of the VRF functions. In general, however, we just derive them from a natural. Since the nonce is a hash, we do not want to recover it to find a preimage. In testing, therefore, we just wrap the raw natural, which we then encode into the fake VRF implementation.

Constructors

NatNonce Natural

findPayKeyPairAddr ∷ Addr → Map (KeyHash 'Payment) (KeyPair 'Payment) → KeyPair 'Payment Source #

Find first matching key pair for address. Returns the matching key pair where the first element of the pair matched the hash in addr.

findPayKeyPairCred ∷ ∀ kr. Credential kr → Map (KeyHash kr) (KeyPair kr) → KeyPair kr Source #

Find first matching key pair for a credential. Returns the matching key pair where the first element of the pair matched the hash in addr.

findPayScriptFromCred ∷ ∀ era. Credential 'Witness → Map ScriptHash (Script era, Script era) → (Script era, Script era) Source #

Find matching multisig scripts for a credential.

findStakeScriptFromCred ∷ Credential 'Witness → Map ScriptHash (Script era, Script era) → (Script era, Script era) Source #

Find first matching script for a credential.

findPayScriptFromAddr ∷ ∀ era. Addr → Map ScriptHash (Script era, Script era) → (Script era, Script era) Source #

Find first matching multisig script for an address.

genBool ∷ Gen Bool Source #

genCoinList ∷ Integer → Integer → Int → Gen [Coin] Source #

Generates a list of Coin values of length between lower and upper and with values between minCoin and maxCoin.

genInteger ∷ Integer → Integer → Gen Integer Source #

genNatural ∷ Natural → Natural → Gen Natural Source #

Generator for a natural number between lower and upper

genWord64 ∷ Word64 → Word64 → Gen Word64 Source #

Generator for a Word64 between lower and upper

genTxOut ∷ ∀ era. EraTxOut era ⇒ Gen (Value era) → [Addr] → Gen [TxOut era] Source #

Generates a list of coins for the given Addr and produced a TxOut for each Addr

Note: we need to keep the initial utxo coin sizes large enough so that when we simulate sequences of transactions, we have enough funds available to include certificates that require deposits.

genesisCoins ∷ TxId → [TxOut era] → UTxO era Source #

Creates the UTxO for a new ledger with the specified genesis TxId and transaction outputs.

increasingProbabilityAt ∷ Gen a → (a, a) → Gen a Source #

Generate values the given distribution in 90% of the cases, and values at the bounds of the range in 10% of the cases.

This can be used to generate enough extreme values. The exponential and linear distributions provided by hedgehog will generate a small percentage of these (0-1%).

pickStakeKey ∷ KeyPairs → Gen (VKey 'Staking) Source #

Select one random verification staking key from list of pairs of KeyPair.

Create a block with a faked VRF result.

mkOCert ∷ ∀ c (r ∷ KeyRole). Crypto c ⇒ AllIssuerKeys c r → Word64 → KESPeriod → OCert c Source #

getKESPeriodRenewalNo ∷ AllIssuerKeys h r → KESPeriod → Integer Source #

Takes a sequence of KES hot keys and checks to see whether there is one whose range contains the current KES period. If so, return its index in the list of hot keys.

tooLateInEpoch ∷ SlotNo → Bool Source #

True if the given slot is within the last `2 * stabilityWindow` slots of the current epoch.
