## Bitmasking

Bitmasking is a technique that uses bitwise operators to manipulate or query specific bits within a data word. It allows developers to perform multiple operations on a single variable, which is highly efficient for managing complex states.

For example, a single 256-bit integer can store dozens of individual flags or small values, each accessible through specific bitmasks. By applying AND, OR, or XOR operations, developers can read or modify these values without affecting others.

This method is essential for high-performance smart contracts where minimizing storage writes is a priority. Bitmasking reduces the need for multiple storage slots, directly lowering gas fees.

It requires a deep understanding of binary arithmetic and the underlying storage structure of the virtual machine. It is a powerful tool for optimizing both storage and computational logic in decentralized protocols.
