Blockchain trilemma: security, decentralization, scalability—three goals that clash. Recent strides show a path forward. Layer‑2 rollups keep data on‑chain while off‑loading computation, preserving decentralization. Sharding splits state, boosting throughput. Proof‑of‑Stake keeps nodes honest with less energy. Together, they bring a future where every transaction is fast, fair, and safe.
