Ever wondered how blockchains keep up? Layer‑1 scaling like sharding or larger blocks boosts throughput but can dilute decentralization. Layer‑2 rollups—optimistic or zk—offload work off‑chain, giving speed and lower fees, yet rely on fraud proofs or heavy proofs. Sidechains add flexibility but risk weaker security. Each choice shapes the future of scaling.
