Scalability is the beating heart of crypto growth. Layer‑2 rollups—Optimistic and zk—bundle thousands of transactions off‑chain, keeping on‑chain security while adding a short wait or heavy proofs. Sharding splits the network into parallel shards, boosting throughput but diluting security and coordination. Sidechains run independent consensus for speed, at the cost of trust. Each trade‑off balances speed, security, and decentralization—choose what fits your use case.
