Layer2 networks were never meant to be mere throughput boosters; their real value is to act as experimental sandboxes where bold ideas can be battle-tested without endangering Ethereum main-net. Arbitrum tinkers with DAO governance, Optimism pilots RetroPGF public-goods funding, Base experiments with CEX integration, and ZKSync pushes account-abstraction forward. Each of these initiatives would be far too risky to deploy directly on L1, yet on a Layer2 they enjoy a controlled arena for trial and error.

From Universal Chains to Vertical Solutions
Different Layer2s can now speak to radically different user bases: a compliance-first enterprise chain, a censorship-resistant privacy chain, a high-frequency gaming chain, and so on. None has yet become the fabled “savior” that funnels infinite traffic back to Ethereum, but together they have expanded the design space of scalability solutions more than any single monolithic chain ever could.

Why Not Just Spin Up a New L1?
Standalone chains such as Hyperliquid or the forthcoming Wall-Street enterprise L1s can deliver silky UX, yet they do so by trading away decentralization. A Layer2, by contrast, inherits Ethereum’s hardened security guarantees. Token incentives may look similar on the surface, yet the underlying commitment to decentralization is what sets the two models apart.

The Road Ahead: Specific-Chain Strategies
The path forward is clear: abandon the “general-purpose everything” mindset and double-down on vertical specialization. Future breakthroughs will come from:

• Licensing beloved gaming IPs

• Building privacy-preserving yet compliant rails

• Serving AI agents that demand millisecond settlement

• Tokenizing real-world assets under strict regulatory umbrellas

Success will hinge less on squeezing another 10× out of the tech stack and more on deep integration with TradFi business logic
