WebHash tree (persistent data structure) In computer science, a hash tree (or hash trie) is a persistent data structure that can be used to implement sets and maps, intended to replace hash tables in purely functional programming. In its basic form, a hash tree stores the hashes of its keys, regarded as strings of bits, in a trie, with the actual ... WebMay 7, 2012 · A short explanation of Brent method and Binary Hash Trees.
