Provided Methods§
fn mmr_root(
&self,
__runtime_api_at_param__: <Block as Block>::Hash,
) -> Result<Result<Hash, Error>, ApiError>
fn mmr_root( &self, __runtime_api_at_param__: <Block as Block>::Hash, ) -> Result<Result<Hash, Error>, ApiError>
Return the on-chain MMR root hash.
fn mmr_leaf_count(
&self,
__runtime_api_at_param__: <Block as Block>::Hash,
) -> Result<Result<u64, Error>, ApiError>
fn mmr_leaf_count( &self, __runtime_api_at_param__: <Block as Block>::Hash, ) -> Result<Result<u64, Error>, ApiError>
Return the number of MMR blocks in the chain.
fn generate_proof(
&self,
__runtime_api_at_param__: <Block as Block>::Hash,
block_numbers: Vec<BlockNumber>,
best_known_block_number: Option<BlockNumber>,
) -> Result<Result<(Vec<EncodableOpaqueLeaf>, LeafProof<Hash>), Error>, ApiError>
fn generate_proof( &self, __runtime_api_at_param__: <Block as Block>::Hash, block_numbers: Vec<BlockNumber>, best_known_block_number: Option<BlockNumber>, ) -> Result<Result<(Vec<EncodableOpaqueLeaf>, LeafProof<Hash>), Error>, ApiError>
Generate MMR proof for a series of block numbers. If best_known_block_number = Some(n)
,
use historical MMR state at given block height n
. Else, use current MMR state.
fn verify_proof(
&self,
__runtime_api_at_param__: <Block as Block>::Hash,
leaves: Vec<EncodableOpaqueLeaf>,
proof: LeafProof<Hash>,
) -> Result<Result<(), Error>, ApiError>
fn verify_proof( &self, __runtime_api_at_param__: <Block as Block>::Hash, leaves: Vec<EncodableOpaqueLeaf>, proof: LeafProof<Hash>, ) -> Result<Result<(), Error>, ApiError>
Verify MMR proof against on-chain MMR for a batch of leaves.
Note this function will use on-chain MMR root hash and check if the proof matches the hash.
Note, the leaves should be sorted such that corresponding leaves and leaf indices have the
same position in both the leaves
vector and the leaf_indices
vector contained in the [LeafProof]
fn verify_proof_stateless(
&self,
__runtime_api_at_param__: <Block as Block>::Hash,
root: Hash,
leaves: Vec<EncodableOpaqueLeaf>,
proof: LeafProof<Hash>,
) -> Result<Result<(), Error>, ApiError>
fn verify_proof_stateless( &self, __runtime_api_at_param__: <Block as Block>::Hash, root: Hash, leaves: Vec<EncodableOpaqueLeaf>, proof: LeafProof<Hash>, ) -> Result<Result<(), Error>, ApiError>
Verify MMR proof against given root hash for a batch of leaves.
Note this function does not require any on-chain storage - the proof is verified against given MMR root hash.
Note, the leaves should be sorted such that corresponding leaves and leaf indices have the
same position in both the leaves
vector and the leaf_indices
vector contained in the [LeafProof]
