The purpose of this data structure is to provide persistent storage for key-value pairs (say to store account balances) such that a deterministic merkle root hash can be computed. The tree is balanced using a variant of the AVL algorithm so all operations are O (log (n)). Nodes of this tree are immutable and indexed by their hash.

For some arbitrary node in the tree, we can derive its value by applying a hash function on the values of all of its children nodes [8]. One can think of a merkle tree as a set. By applying the deﬁnition of a node’s value, inserting data into a merkle tree can be thought of as a commitment to the data. date of birth bradley chubb
