Layer‑1 scaling pushes protocol limits—sharding and PoS raise throughput but can dilute decentralization and require heavy changes. Layer‑2 rollups keep base chain secure while batching transactions, yet they depend on underlying L1 consensus and can face data availability concerns. Sidechains offer speed and flexibility but trade off security for speed. Choosing the right mix depends on your risk tolerance and desired performance.
