When it comes to blockchain scalability, people’s minds are always filled with TPS numbers—bigger is better. But if we look at privacy-compliant Layer-1 solutions from a different perspective, the logic might actually be reversed.

Take projects like Dusk as an example. If your application scenario doesn’t involve high-frequency matching or complex derivatives settlement, blindly stacking Layer-2 solutions for speed might actually be a waste of effort.

The reason the Lightspeed Layer-2 plan exists is based on a prerequisite—the application must face a real dilemma: privacy computing latency versus the market’s extreme demand for liquidity. Lightspeed’s ambition is quite clear: to support matching engines comparable to traditional securities exchanges. In other words, only when on-chain asset trading frequency is so high that millisecond-level responses are needed, and each order must be invisible to the counterparty (to prevent front-running), do you truly need a Rollup that inherits the mainnet’s privacy features and can handle ultra-high concurrency.

For ecosystem builders, the real motivation to integrate Lightspeed shouldn’t just be about “speed,” but about—are you really trying to replicate a decentralized NASDAQ on-chain? If your application is limited to low-frequency asset storage or simple peer-to-peer transfers, the existing instant finality of the Dusk mainnet is already sufficient.

In simple terms: whether to adopt a scalability solution depends on whether your business scenario actually has that need.
