## Bitmap Indices

Bitmap indices are a data structure that uses bit arrays to represent the presence or absence of specific values or attributes in a dataset. Each bit in the array corresponds to a unique record, where a value of one indicates the attribute is present and zero indicates it is absent.

This method is highly efficient for performing complex queries and filtering operations because it relies on fast bitwise logical operations like AND, OR, and XOR. In a blockchain context, bitmap indices can be used to track user statuses, such as whether an account is eligible for a certain liquidity pool or has participated in a specific governance vote.

Because these operations are computationally inexpensive, they help keep gas costs low even when dealing with large numbers of participants. They provide a compact way to store and query categorical data.

By leveraging bitwise logic, developers can execute complex filters that would otherwise require expensive iterations over large arrays.
