Definition ∞ Tower Defense is a popular genre of strategy video games where players construct defensive structures, typically towers, to prevent waves of enemies from reaching a designated objective. Players strategically place and upgrade these defenses along a predefined path or within an open field to optimize their effectiveness against various enemy types. The core gameplay involves resource management, tactical placement, and anticipating enemy movements. It challenges players to design efficient defensive layouts.
Context ∞ While primarily a gaming genre, Tower Defense principles can conceptually relate to blockchain security models, where network nodes or validators act as “towers” defending the network against malicious actors or attacks. The strategic allocation of resources, such as staked tokens, to secure the network against various threats bears a conceptual similarity to optimizing defenses. Discussions in crypto news might draw parallels when explaining network resilience or the economic security models of decentralized protocols.
