Crate tp_consensus_babe

Primitives for BABE.

Modules

digests	Private implementation details of BABE digests.
inherents	Inherents for BABE

Structs

BabeEpochConfiguration	Configuration data used by the BABE consensus engine.
BabeGenesisConfiguration	Configuration data used by the BABE consensus engine.
BabeGenesisConfigurationV1	Configuration data used by the BABE consensus engine.
Epoch	BABE epoch information
OpaqueKeyOwnershipProof	An opaque type used to represent the key ownership proof at the runtime API boundary. The inner value is an encoded representation of the actual key ownership proof which will be parameterized when defining the runtime. At the runtime API boundary this type is unknown and as such we keep this opaque representation, implementors of the runtime API will have to make sure that all usages of OpaqueKeyOwnershipProof refer to the same type.
Slot	Unit type wrapper that represents a slot.
Transcript	A transcript of a public-coin argument.

Enums

AllowedSlots	Types of allowed slots.
ConsensusLog	An consensus log item for BABE.

Constants

BABE_ENGINE_ID	The ConsensusEngineId of BABE.
BABE_VRF_PREFIX	The prefix used by BABE for its VRF keys.
KEY_TYPE	Key type for BABE module.
MEDIAN_ALGORITHM_CARDINALITY	How many blocks to wait before running the median algorithm for relative time This will not vary from chain to chain as it is not dependent on slot duration or epoch length.
PUBLIC_KEY_LENGTH	The length of the public key
RANDOMNESS_LENGTH	The length of the Randomness.
VRF_OUTPUT_LENGTH	Length of VRF output.
VRF_PROOF_LENGTH	Length of the short VRF proof which lacks support for batch verification.

Statics

BABE_VRF_INOUT_CONTEXT

BABE VRFInOut context.

Traits

BabeApi

API necessary for block authorship with BABE.

Functions

check_equivocation_proof	Verifies the equivocation proof by making sure that: both headers have different hashes, are targetting the same slot, and have valid signatures by the same authority.
make_transcript	Make a VRF transcript from given randomness, slot number and epoch.
make_transcript_data	Make a VRF transcript data container

Type Definitions

AuthorityId	A Babe authority identifier. Necessarily equivalent to the schnorrkel public key used in the main Babe module. If that ever changes, then this must, too.
AuthorityIndex	The index of an authority.
AuthorityPair	A Babe authority keypair. Necessarily equivalent to the schnorrkel public key used in the main Babe module. If that ever changes, then this must, too.
AuthoritySignature	A Babe authority signature.
BabeAuthorityWeight	The weight of an authority.
BabeBlockWeight	The weight of a BABE block.
EquivocationProof	An equivocation proof for multiple block authorships on the same slot (i.e. double vote).
Randomness	Schnorrkel randomness value. Same size as VRFOutput.
