Abstract Security Model

Definition ∞ An abstract security model provides a high-level framework that defines the security properties and assumptions of a digital system. It outlines the fundamental requirements for data integrity, confidentiality, and availability, independent of specific implementation details. This model helps assess potential vulnerabilities and design robust defense mechanisms for distributed ledgers. Its primary purpose is to ensure the reliable operation and protection of digital assets and transactional data within a given architecture.
Context ∞ Discussions surrounding abstract security models frequently appear in news concerning new blockchain protocols or updates to existing ones. Evaluating these models assists in understanding the theoretical resilience of a digital asset system against various attacks. Ongoing developments focus on formal verification methods to validate these models rigorously, ensuring their practical applicability.
