Layer‑2 rollups, sharding, and sidechains are the main paths to scale. Rollups bundle off‑chain txs, commit proofs on‑main for speed and low fees, but rely on the host chain’s security. Sharding splits the network into shards, boosting throughput but adding inter‑shard coordination. Sidechains run their consensus, freeing the main chain but risking centralization. Choosing the right mix balances speed, cost, and decentralization.
