Blockchain Trilemma
The design claim that a consensus system optimizes at most two of decentralization, security, and scalability: Nakamoto consensus buys decentralized security with low throughput, DPoS buys throughput with a small validator set, and Gasper-style designs pay in protocol complexity. It frames every consensus mechanism as a chosen point in this tradeoff space rather than a strict impossibility result.
This Concept is waiting for its first lesson!
