Scalability is the heart of the next‑gen crypto. Layer‑2 rollups bundle thousands of txs off‑chain and post proofs to mainnet, giving speed and low fees but relying on the host chain’s security. Sharding splits the chain into shards, boosting throughput but adding complexity and cross‑shard sync costs. Sidechains grant flexibility and custom rules, yet they trade decentralisation for interoperability. Pick the right mix for your use case.
