## Transaction Validity Verification

Transaction Validity Verification is the process by which a node confirms that a transaction follows all network rules before including it in a block. This involves checking digital signatures, ensuring the sender has sufficient funds, and validating the smart contract logic.

This process is the first line of defense against malicious activity. It ensures that only authorized and correct state changes are recorded on the ledger.

Verification must be performed rapidly to maintain high transaction throughput. It is a computationally intensive task that is optimized by modern blockchain clients.

Without rigorous verification, the integrity of the entire system would be compromised. It is a critical component of the node's software stack.
