The hype around Ethereum’s Layer 2 (L2) scaling solutions is overwhelming. We’re misled into thinking they are the only means to attain mass adoption. Their hype has some people questioning if they’re really Ethereum’s salvation, or if they’re unwittingly draining the main chain’s lifeblood. Have we become so entranced by the glow of scalability that we’re overlooking its ugly underbelly?

L2s: Scalability At What Cost?

Let's be clear: Ethereum needed scaling solutions. Gas fees on L1 were, and still are at times, L1 friendly costs. Picture that every time you go to buy a coffee, you’re hitting $50 in transaction costs. Absurd, right? L2s including Arbitrum and Optimism filled the void, providing users cheaper and faster transactions. The initial enthusiasm was palpable. That big win is beginning to look a little…empty.

So Quinn Thompson’s statement that ETH is “entirely dead” as an investment probably qualifies as hyperbole. Is it entirely wrong? Nic Carter’s agreement exposing the “greedy” L2s poses a relevant and real concern.

The data paints a complex picture. L2s have undeniably increased transaction throughput. Look closer. What’s going on with demand for ETH itself? Are we just diverting activity from the core chain, in a sense killing it by starvation? In the process, are we not exchanging the long-term health of Ethereum for short-term gain in transaction speed?

Consider this analogy: Imagine a city (Ethereum L1) with a thriving central business district (DeFi, NFTs, etc.). A network of privately built and maintained L2 “express lanes” quickly blankets the metro. She noted that these lanes provide faster, high-quality travel from origin to destination. Initially, everyone is excited about the speed. But eventually, businesses in the central district begin to struggle as less and less people walk through. The city becomes fragmented. Is that truly progress?

ETH Burn: Usage Doesn't Equal Value?

Scott Johnsson from the Ethos Academy explains how the more Ethereum is used and the more ETH that’s burned, the more valuable ETH may become. A neoclassical theory of an inverse relationship between burn and transaction volume. Sounds great, in theory. Thompson's rebuttal hits hard: where is the sustained period of this actually happening?

The hope for a deflationary ETH supply was a big part of the early ETH investment thesis. If L2s are indeed minimizing activity on the core chain, they are affecting the burn rate. Less activity, less burn, potentially more inflation. Suddenly, that compelling narrative starts to crumble.

What if high ETH prices are actually a feature, not a bug? Think about it. High gas fees incentivize people to migrate to L2s, which in turn scales the entire Ethereum ecosystem to reach more users. It’s an often painful, Darwinian, but necessary process that compels such innovation and adoption. Have we become so addicted to the quick-hit, the low-cost deal, that we ignore the long term?

Centralization: The Silent Killer?

Scalability can’t be achieved by sacrificing decentralization. It's the core principle of blockchain technology. Yet, L2s introduce new points of centralization. This leads to a situation on some of these networks where a handful of entities control the sequencers and validators. Now are we really just trading one set of problems (high gas fees) with another (centralized control).

Look at the history of the internet. Initially, it was decentralized and open. Over the years, that power was funneled over to a few big tech companies. Have we learned nothing and are now making the same mistake with Ethereum? Are we sleepwalking into a future where a handful of L2 operators control the vast majority of Ethereum's economic activity?

What the long-term impact of L2s on Ethereum will be is an open question. However, much more data and analysis are needed to understand the significant implications. This requires us to ask hard questions and question the assumptions of conventional wisdom. It’s time to stop accepting at face value the idea that L2s are the cure-all. All of Ethereum’s future depends on it.

The long-term impact of L2s on Ethereum remains an open question. More data and analysis are needed to fully understand the implications. We need to ask tough questions, challenge conventional wisdom, and avoid blindly accepting the narrative that L2s are a panacea. The future of Ethereum hangs in the balance.
