Ouroboros.Consensus.Shelley.Protocol.Abstract

Description

Commonality between multiple protocols.

Everything in this module is indexed on the protocol (or the crypto), rather than on the block type. This allows it to be imported in Ouroboros.Consensus.Shelley.Ledger.Block.

class (Eq (EnvelopeCheckError proto), NoThunks (EnvelopeCheckError proto), Show (EnvelopeCheckError proto)) ⇒ ProtocolHeaderSupportsEnvelope proto where Source #

Indicates that the header (determined by the protocol) supports " Envelope " functionality. Envelope functionality refers to the minimal functionality required to construct a chain.

pHeaderBlockSize ∷ ShelleyProtocolHeader proto → Natural Source #

envelopeChecks ∷ ConsensusConfig proto → LedgerView proto → ShelleyProtocolHeader proto → Except (EnvelopeCheckError proto) () Source #

Carry out any protocol-specific envelope checks. For example, this might check things like maximum header size.

class ProtocolHeaderSupportsKES proto where Source #

ProtocolHeaderSupportsKES describes functionality common to protocols using key evolving signature schemes. This includes verifying the header integrity (e.g. validating the KES signature), as well as constructing the header (made specific to KES-using protocols through the need to handle the hot key).

Methods

configSlotsPerKESPeriod ∷ ConsensusConfig proto → Word64 Source #

Extract the "slots per KES period" value from the protocol config.

Note that we do not require ConsensusConfig in verifyHeaderIntegrity since that function is also invoked with StorageConfig.

verifyHeaderIntegrity Source #

Arguments

∷ Word64

Slots per KES period

→ ShelleyProtocolHeader proto 
→ Bool 

Verify that the signature on a header is correct and valid.

mkHeader Source #

Arguments

∷ ∀ crypto m. (Crypto crypto, Monad m, crypto ~ ProtoCrypto proto) 
⇒ HotKey crypto m 
→ CanBeLeader proto 
→ IsLeader proto 
→ SlotNo

Slot no

→ BlockNo

Block no

→ PrevHash crypto

Hash of the previous block

→ Hash crypto EraIndependentBlockBody

Hash of the block body to include in the header

→ Int

Size of the block body

→ ProtVer

Protocol version

→ m (ShelleyProtocolHeader proto)
