## Mempool Message Integrity

Mempool Message Integrity refers to the mechanisms used to ensure that transactions waiting in the mempool have not been altered or corrupted before being included in a block. This involves verifying digital signatures and transaction hashes to guarantee that the transaction remains exactly as the user intended.

In an environment where transactions are public and potentially subject to front-running or other interference, maintaining the integrity of the message is paramount. If a transaction is modified in the mempool, it could result in the execution of an unintended action or the loss of funds.

Mempool integrity is a critical aspect of transaction security, protecting the user's intent from the moment of submission until the moment of inclusion. It is a key factor in the overall reliability of the network.

These integrity checks are performed by nodes as they propagate and store transactions, ensuring that only valid and unaltered messages reach the block producers. This is a vital defense against transaction-level attacks.

It ensures that the network acts as a trustworthy medium for value transfer.
