In cryptography and computer science Hash trees or Merkle trees are a type of data structure which contains a tree of summary information about a larger piece of data – for instance a file – used to verify its contents. Hash trees are an extension of hash lists, which in turn are an extension of hashing. Hash trees in which the underlying hash function is Tiger are often called Tiger trees or Tiger tree hashes.
