Constrained Optimality describes the best possible outcome or state achievable for a system, given a specific set of limitations or restrictions. It signifies reaching a peak performance level within predefined boundaries. This concept acknowledges that absolute perfection is often unattainable, focusing instead on maximizing results under practical conditions.
Context
In blockchain design, constrained optimality is frequently observed in the trade-offs between decentralization, security, and scalability, often termed the “blockchain trilemma.” Protocols strive to achieve the best possible balance among these attributes, recognizing that optimizing one may necessitate compromises in others. This principle guides the architectural decisions in developing new digital asset platforms.
Introducing the MINSLACK mechanism, this work formally resolves the PoS utility-security trade-off by dynamically constraining validator exits to maintain crypto-economic safety.
