Crate beefy_primitives[−][src]
Expand description
Primitives for BEEFY protocol.
The crate contains shared data types used by BEEFY protocol and documentation (in a form of code) for building a BEEFY light client.
BEEFY is a gadget that runs alongside another finality gadget (for instance GRANDPA).
For simplicity (and the initially intended use case) the documentation says GRANDPA in places
where a more abstract “Finality Gadget” term could be used, but there is no reason why BEEFY
wouldn’t run with some other finality scheme.
BEEFY validator set is supposed to be tracking the Finality Gadget validator set, but note that
it will use a different set of keys. For Polkadot use case we plan to use secp256k1 for BEEFY,
while GRANDPA uses ed25519.
Modules
BEEFY cryptographic types
BEEFY + MMR utilties.
Primitives for light, 2-phase interactive verification protocol.
Structs
A commitment signed by GRANDPA validators as part of BEEFY protocol.
A commitment with matching GRANDPA validators’ signatures.
A set of BEEFY authorities, a.k.a. validators.
BEEFY vote message.
