## Merkle Patricia Trees

Merkle Patricia Trees are a specialized data structure that combines the properties of a Merkle tree and a Patricia trie to store key-value pairs efficiently. They are widely used in blockchain platforms like Ethereum to store the global state, including account balances and smart contract data.

The structure allows for fast lookups, insertions, and deletions while maintaining a cryptographic root that summarizes the entire dataset. Because it is a prefix tree, it saves space by sharing common prefixes among keys, making it highly efficient for storing large amounts of state data.

Any change to the data results in a new root hash, which is essential for tracking state transitions across blocks. It is a highly optimized way to manage complex data states in a decentralized environment.
