Scaling still the biggest hurdle. Layer‑1 upgrades like sharding boost raw throughput but risk centralisation. Layer‑2 roll‑ups keep base‑chain security while slashing fees, yet require users to trust operators. Sidechains offer speed but trade a weaker security model. Pick the right mix: high‑throughput for payments, roll‑ups for dApps, and sharding for future‑proofing.
