EVM Security Model

Definition ∞ The EVM security model is the set of rules and safeguards protecting applications on Ethereum-compatible blockchains. This refers to the architectural and operational framework that defines how smart contracts execute and interact within the Ethereum Virtual Machine environment, including its inherent protections against common vulnerabilities. This model governs transaction validity, state transitions, and gas mechanisms, establishing a secure, deterministic execution context. Understanding its parameters is crucial for developing robust and resilient decentralized applications.
Context ∞ Discussions in crypto news often focus on the strengths and weaknesses of the EVM security model, especially in the context of smart contract exploits and audits. The continuous development of tools and practices aims to fortify this model against emerging threats and reduce attack surfaces. The ongoing efforts to enhance EVM security are central to the overall trustworthiness of the Ethereum ecosystem and its many derivative chains.
