Don’t believe the noise: There can never be too many L2s

The proliferation of Layer 2 (L2) scaling solutions on Ethereum, with a new one launching approximately every 19 days, has sparked debate within the Web3 community. Critics argue that this rapid expansion leads to fragmentation and redundancy, suggesting a saturation point has been reached. However, this perspective overlooks the long-term potential and necessity of specialized L2s.

The analogy to the early days of the internet is apt. The vast number of websites in existence today wasn’t deemed excessive in 1998; similarly, the current number of L2 blockchains is still relatively small compared to the potential for growth and specialization. This expansion isn’t a fleeting trend driven by decentralized finance (DeFi) enthusiasts; instead, it reflects a crucial shift in enterprise-grade infrastructure adoption.

Banks, game studios, logistics networks, and manufacturers are increasingly adopting L2s to overcome limitations of public Layer 1 (L1) blockchains. These risk-averse industries require custom performance, predictable costs, jurisdictional compliance, and granular-level privacy—features often lacking in shared L1 environments. This mirrors the historical development of the internet, where companies like Facebook, Netflix, and JPMorgan didn’t share a single platform. Similarly, shared L1s are insufficient for the complex requirements of real-world businesses.

The increasing viability of L2s is due to advancements in modular stacks, rollup-as-a-service platforms, and zero-knowledge proof technology. These advancements lower the cost and complexity of launching and maintaining specialized chains, further fueling L2 growth. Concerns about user experience and liquidity fragmentation due to numerous chains are short-sighted. Future interoperability solutions, such as shared settlement layers and unified account abstraction, will address these challenges. Ultimately, users will transact seamlessly, regardless of the underlying L2.

The analogy to cloud computing is relevant. Cloud computing abstracted the hardware layer, enabling hyper-scale; modular blockchains similarly unlock hyper-scale for value transfer and asset issuance. Specialized L2s, far from competing, will cater to diverse verticals and use cases, coexisting harmoniously. Betting against the proliferation of L2s is betting against the fundamental principles of scale and sovereignty. The future points towards a modular, scalable ecosystem comprised of hundreds of L2s supporting thousands of use cases.
