MerklePatriciapuut
MerklePatriciapuut is the term used for Merkle Patricia trees, a family of authenticated data structures that blend Merkle trees with a Patricia trie to provide a compact, tamper-evident key-value store with efficient proofs of membership and non-membership. In English-language sources the standard term is Merkle Patricia Trie (MPT); MerklePatriciapuut appears in some non-English renderings or as a localized name.
Its structure consists of a trie-like tree where nodes can be extension, leaf, or branch nodes. Each
Merkle Patricia trees are widely used in blockchain systems to store state in a way that enables
Advantages include compact proofs, deterministic lookup times, and efficient synchronization between peers. Limitations include the complexity
