## Unstructured Storage

Unstructured storage is a technique used in proxy contracts to prevent storage collisions by storing data in arbitrary, randomized storage slots. Instead of relying on the standard Solidity variable ordering, developers use the keccak256 hash of a string to determine the location of a variable.

This ensures that the proxy logic and the implementation logic do not overlap in the contract memory. It allows for more flexible contract upgrades without the need to maintain strict variable orderings.

This method is considered a robust way to handle state in upgradeable systems. It is a fundamental pattern for modern smart contract architecture.
