CONVEX AND CONCAVE DISPOSITIONS

Summary from the TLDR Crypto newsletter

Vitalik Buterin introduces a decision-making framework that distinguishes "concave disposition" (favoring compromise/middle ground) from "convex disposition" (favoring commitment to extremes), using Bitcoin's all-or-nothing approach to decentralization versus Ethereum's pragmatic willingness to accept tradeoffs as primary examples. He argues most real-world decisions are multidimensional "saddle points" that are simultaneously convex in some dimensions and concave in others, meaning effective protocol design requires identifying which aspects demand purity versus which benefit from balance. The framework challenges the crypto industry's tendency toward single-dimensional thinking in governance debates.
