API to interact with MMR pallet.

Provided Methods§

Generate MMR proof for a leaf under given index.

Generate MMR proof for a leaf under given index.

Verify MMR proof against on-chain MMR.

Note this function will use on-chain MMR root hash and check if the proof matches the hash. See Self::verify_proof_stateless for a stateless verifier.

Verify MMR proof against on-chain MMR.

Note this function will use on-chain MMR root hash and check if the proof matches the hash. See Self::verify_proof_stateless for a stateless verifier.

Verify MMR proof against given root hash.

Note this function does not require any on-chain storage - the proof is verified against given MMR root hash.

The leaf data is expected to be encoded in its compact form.

Verify MMR proof against given root hash.

Note this function does not require any on-chain storage - the proof is verified against given MMR root hash.

The leaf data is expected to be encoded in its compact form.

Return the on-chain MMR root hash.

Return the on-chain MMR root hash.

Generate MMR proof for a series of leaves under given indices.

Generate MMR proof for a series of leaves under given indices.

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 BatchProof

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 BatchProof

Verify MMR proof against given root hash or 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 BatchProof
