For years, the "Scalability-Security-Decentralization Trilemma" was considered an unbreakable law of blockchain physics. However, at the recent ETH ChiangMai event, Vitalik Buterin challenged this notion, declaring it an engineering problem rather than a mathematical impossibility. This quest explores how Ethereum is using cutting-edge technologies like zk-SNARKs and PeerDAS to break this mold, moving from theoretical trade-offs to a future where high capacity and decentralization coexist.
