   What are Merkle Trees and Proofs?

   Merkle trees are a data structure used to verify data presence efficiently within a blockchain without downloading the entire chain. They consist of hashed data organized in a tree-like structure to ensure data authenticity through hashing and comparing nodes. Merkle proofs allow users to verify the presence of specific data in the tree without accessing the whole structure, optimizing data storage and verification processes.
