Cryptographic hashes can be non-deterministic

WebIrreversible: Unlike encryption, Cryptographic Hash Functions are one-way. Once encrypted, you can never decrypt them even if you have the exact hashing algorithm that was used for the encryption. Simply put, there is no decryption in CHFs. Hence, they are irreversible.

Webstructure. Most implemented hash trees require the use of a cryptographic hash function h in order to prevent collisions. Like most hash trees, the Merkle tree is a binary tree, so each internal node N ij is the hash value of the concatenation of its two children: N ij =h(N i-1 ,0 N i-1 ,1), where i is the depth of node in the tree.
