Blockchain trilemma—security, decentralization, scalability—has long been a design puzzle. Today hybrid solutions are closing the gap: PoS + sharding on Ethereum 2.0, roll‑ups on L2, and zk‑rollups on Solana. Layer‑2 scaling boosts throughput while keeping consensus secure, letting networks grow without centralizing. The next era is about layering, not choosing one trait.
