Scalability isn't a one‑size‑fits‑all. Layer‑1 upgrades like sharding or PoS‑based blockchains boost native throughput but often trade off decentralization or require heavy hardware. Layer‑2 roll‑ups (Optimistic, ZK) keep base chain secure and cheap, but depend on off‑chain data availability and can introduce complexity. Sidechains offer speed but risk centralization. Choosing the right mix hinges on your risk appetite, cost, and future growth.
