Scalability isn't one‑size‑fits‑all. Layer‑1 sharding boosts throughput but splits security across shards. Roll‑ups—optimistic or zk—compute off‑chain with on‑chain proof, keeping base chain lean but adding a trust layer. Sidechains trade decentralization for speed, while state‑channels offer instant micro‑txs but limited scope. Pick the mix that balances speed, safety, and user experience for your project.
