Scaling blockchains is a race between speed, security, and decentralization. Layer‑1 sharding boosts raw throughput but stretches consensus; rollups (Optimistic, zk) keep the main chain safe while packing many off‑chain txs; sidechains trade security for speed and require bridge trust. Each path trades decentralization for performance—pick the one that fits your use case.
