Rational security in blockchain protocols refers to the principle that the network’s integrity and functionality are maintained because it is economically disadvantageous for participants to act maliciously. This security model relies on game theory, where honest behavior is incentivized through rewards, and dishonest actions are deterred by significant financial penalties. It assumes that all network participants are rational actors. This approach aligns economic interests with protocol adherence.
Context
This security model is central to the design of many proof-of-stake blockchains, where validators are economically bound to act honestly. Crypto news often discusses the effectiveness of rational security in preventing attacks and maintaining network stability. The ongoing analysis of economic incentives and their impact on participant behavior is a critical aspect of evaluating a protocol’s long-term resilience.
This research introduces Cryptographic Whistleblowing, a mechanism design primitive that uses provable on-chain penalties to enforce honesty against financially rational colluders.
