True blockchain progress hinges on breaking the trilemma: security, decentralization, scalability. Layer‑2 rollups boost throughput without sacrificing decentralization. Sharding and hybrid PoS‑PoW designs improve security while keeping node counts high. Protocols that combine these—e.g., Ethereum 2.0, Solana, Polkadot—show that trade‑offs can be nudged, not erased. The future lies in layered, interoperable ecosystems that evolve together.
