}

Substrate-based chain with BEEFY && MMR pallets deployed.

Both BEEFY and MMR pallets and their clients may be configured to use different primitives. Some of types can be configured in low-level pallets, but are constrained when BEEFY+MMR bundle is used.

Required Associated Types

type CommitmentHasher: Hash

The hashing algorithm used to compute the digest of the BEEFY commitment.

Corresponds to the hashing algorithm, used by sc_consensus_beefy::BeefyKeystore.

type MmrHashing: Hash<Output = Self::MmrHash>

The hashing algorithm used to build the MMR.

The same algorithm is also used to compute merkle roots in BEEFY (e.g. validator addresses root in leaf data).

Corresponds to the Hashing field of the pallet-mmr configuration.

type MmrHash: Hash + Parameter + Copy + AsRef<[u8]> + Default + MaybeSerializeDeserialize + PartialOrd

The output type of the hashing algorithm used to build the MMR.

This type is actually stored in the MMR. Corresponds to the Hash field of the pallet-mmr configuration.

type BeefyMmrLeafExtra: Parameter

The type expected for the MMR leaf extra data.

type AuthorityId: BeefyAuthorityId<Self::CommitmentHasher> + Parameter

A way to identify a BEEFY validator.

Corresponds to the BeefyId field of the pallet-beefy configuration.

type AuthorityIdToMerkleLeaf: Convert<Self::AuthorityId, Vec<u8>>

A way to convert validator id to its raw representation in the BEEFY merkle tree.

Corresponds to the BeefyAuthorityToMerkleLeaf field of the pallet-beefy-mmr configuration.
