Chain Reorganization Resistance

Chain

⎊ A blockchain’s inherent resistance to reorganization, specifically concerning the probabilistic cost of reverting confirmed blocks, directly impacts the security assumptions underpinning derivative contracts settled on that chain. This resistance is quantified by the computational power required to successfully mount a 51% attack, influencing the confidence intervals for option pricing and the validity of collateralized debt positions. Consequently, lower reorganization resistance increases counterparty risk within decentralized finance (DeFi) protocols and necessitates higher capital reserves for market makers.
