Crypto-economic security refers to the design principle where a blockchain network’s safety and integrity are maintained through a combination of cryptographic techniques and economic incentives. Participants are motivated to act honestly by potential rewards for good behavior and financial penalties for malicious actions. This balance ensures that the cost of attacking the system outweighs the potential gains.
Context
Discussions about crypto-economic security are fundamental to understanding the resilience of various blockchain protocols, particularly in proof-of-stake systems. News often analyzes how different incentive structures impact network stability, censorship resistance, and overall attack costs. A robust crypto-economic security design is considered essential for the long-term viability and trustworthiness of any decentralized ledger.
Introducing the MINSLACK mechanism, this work formally resolves the PoS utility-security trade-off by dynamically constraining validator exits to maintain crypto-economic safety.
This research extends accountable safety to liveness, introducing 'certificates of guilt' to cryptographically punish nodes that intentionally stall transaction finality.
