Tendermint and Cosmos Cryptographic Types

# Signatures in Tendermint are raw bytes representing the underlying signature
type Signature bytes

# Public key
type PubKey bytes

# Private key
type PrivKey bytes

# AuntCIDs is a list of CID links to the nodes intervening a leaf's sibling and a root node's child
type AuntCIDs [AppStateNodeCID]

# Proof represents a Merkle proof.
# NOTE: The convention for proofs is to include leaf hashes but to
# exclude the root hash.
# This convention is implemented across IAVL range proofs as well.
# Keep this consistent unless there's a very good reason to change
# everything. This also affects the generalized proof system as
# well.
type Proof struct {
Total Int # Total number of items.
Index Int # Index of item to prove.
LeafCID AppStateNodeCID # CID link to the leaf containing the item to prove.
