Hash Tables

A hash table is a data structure that implements an associative array, a structure that can map keys to values. A hash function is used to compute an index into an array of buckets or slots, from which the desired value can be found.

In the context of smart contracts, mappings are the primary implementation of hash tables. They are highly efficient, providing average-case constant-time performance for insertions, deletions, and lookups.

Hash tables are essential for any protocol that needs to manage large amounts of data, such as account balances or order books, where quick access is required. Because they provide fast data retrieval, they are a preferred choice for state management.

Developers must understand how to design keys and manage collisions, although the underlying virtual machine handles most of the collision resolution for standard mappings.
