EOA Security Model

Definition ∞ The EOA Security Model refers to the security framework for Externally Owned Accounts in blockchain systems, where control of assets relies solely on a single private key. Transactions from an EOA are signed directly by this private key, making its compromise a direct threat to all associated assets. This model is foundational to many early cryptocurrency wallets.
Context ∞ News often discusses the limitations and risks of the EOA Security Model, especially when comparing it to more advanced smart contract-based wallet solutions. Incidents of stolen private keys or phishing attacks that compromise EOAs frequently appear, underscoring the need for strong user-side operational security. The evolution toward account abstraction seeks to mitigate some inherent EOA vulnerabilities.
