Foundational Security Model

Definition ∞ A foundational security model defines the fundamental principles, assumptions, and mechanisms that secure a digital system. In the context of blockchain and digital assets, this model outlines how consensus is achieved, how data integrity is maintained, and how participants are incentivized to act honestly. It includes the cryptographic primitives, the consensus algorithm, and the economic game theory underlying the network’s operation. A robust foundational security model is essential for the long-term viability and trustworthiness of any decentralized system.
Context ∞ Discussions about new blockchain architectures, comparisons between different consensus mechanisms, or analyses of protocol vulnerabilities often center on the strengths and weaknesses of their foundational security models. News reports frequently evaluate projects based on the soundness of their underlying security design. The evolution of these models aims to enhance scalability, decentralization, and resistance to various attack vectors.
