## Explain the Difference between “Gas” and “Gas Limit” in a Transaction.

"Gas" refers to the computational effort required to execute an operation on the blockchain, and its cost is measured in the blockchain's native currency. "Gas limit" is the maximum amount of gas a user is willing to spend on a transaction.

Setting a gas limit prevents users from spending excessive funds on a faulty or complex transaction. If the operation costs less than the limit, the user is refunded the difference.

This artifact visually represents the intersection of legacy data infrastructure and future decentralized finance mechanisms, specifically focusing on data integrity necessary for robust smart contract deployment. The polished surface suggests the required transparency in blockchain validation processes, juxtaposed against the intricate circuitry symbolizing the underlying computational complexity of Layer 2 scaling solutions. Consider this depiction as a metaphor for securely tokenizing proprietary trading algorithms or structuring complex portfolio collateralization using undercollateralized synthetic assets. The composition speaks to securing digital property rights through cryptographic primitives, moving beyond traditional centralized custodianship. Understanding this data persistence layer is crucial for advanced users navigating regulated digital asset derivatives markets and understanding the computational overhead associated with on-chain governance proposals and efficient block production validation mechanisms. This image conceptually anchors the need for robust cryptographic solutions to manage distributed ledger technology effectively."
