Definition ∞ Crypto-economic security models utilize a combination of cryptographic proofs and economic incentives to secure decentralized systems against malicious behavior. These models align participant interests with the network’s overall integrity. They ensure that acting honestly is more profitable than attempting to subvert the system.
Context ∞ Crypto-economic security models are fundamental to the stability and reliability of most blockchain protocols and digital assets. News often discusses the efficacy of different proof mechanisms, such as Proof of Work or Proof of Stake, and their role in preventing attacks like 51% attacks. Ongoing research and development focus on refining these models to enhance scalability and resilience, addressing the evolving threat landscape in decentralized networks.
