Block Gas Limits

Gas

⎊ Block gas limits represent the maximum computational effort, measured in units of gas, a transaction can consume within a single block on a blockchain network. This constraint is fundamental to preventing denial-of-service attacks and ensuring network stability by limiting the resources any single transaction can monopolize. The limit directly impacts the complexity of smart contracts that can be executed, influencing the feasibility of decentralized applications and the cost of operations. Consequently, developers must optimize code for gas efficiency, and users must consider gas costs when initiating transactions, particularly within decentralized finance (DeFi) protocols.
