Struct MmrVerifyFromMemory

pub struct MmrVerifyFromMemory;

Check whether a given leaf is a member of a pointed-to MMR, with the inclusion proof (the authentication path) residing in RAM.

Behavior

BEFORE: _ *peaks [leaf_count: u64] [leaf_index: u64] [leaf: Digest] *auth_path
AFTER:  _ [validation_result: bool]

Preconditions

• all input arguments are properly BFieldCodec encoded
• input arguments *peaks points to a properly BFieldCodec encoded list of Digests
• input arguments *auth_path points to a properly BFieldCodec encoded list of Digests
• the leaf_count is consistent with the pointed-to MMR
• the leaf_index is smaller than the leaf_count

Postconditions

• all output is properly BFieldCodec encoded
