Celo’s move from Layer 1 to Ethereum L2 isn’t just technical—it signals a fundamental economic shift in crypto. Independent L1 chains can’t capture revenue because their income directly flows to stakers, leaving no money for R&D growth. L2s, however, can retain and reinvest revenue into innovation and sustainability. As projects become more economically rational, expect more chains to follow Celo, leveraging Ethereum’s security and dramatically reducing costs.

Last week, something big happened in crypto — but only a few % folks grasped its full importance.

Celo announced its move from being a standalone Layer 1 blockchain to becoming an Ethereum Layer 2.

It’s easy to read that as just another technical migration. But in reality, it signals a much broader shift that Ethereum has quietly been pushing toward — one that’s reshaping how we think about building in crypto.

Let’s break it down.

The Industry is Getting Real About Costs and Revenue

We’re in the middle of a long-overdue correction. The crypto market is starting to value fundamentals again. Narrative still matters, but now, people are asking:

• What’s the actual revenue of this chain?
• What are its operating costs?
• Where does value accrue?

A new set of metrics like REV (h/t @smyyguy ) are starting to matter more — and they reveal stark differences between chains that look similar on the surface.

This is where Celo’s decision makes total sense.

L1s Don’t Capture Revenue — L2s Do

Here’s the part that’s often missed in the economic conversation: L1s can’t actually capture revenue in a sustainable way.

Why? Because all the value is routed straight to stakers or miners. The L1 collects fees, and those fees are immediately distributed as block rewards or staking yields. There’s no retained margin. No surplus. Nothing left over to fund innovation or protocol development.

This creates a weird dynamic: L1s can be massively valuable platforms, yet still operate like public infrastructure with no built-in funding mechanism to evolve.

Contrast that with L2s.

L2s can retain and redirect revenue. Sequencer fees, MEV, and even custom tolls on blockspace can be collected and then reinvested: into R&D, developer grants, growth campaigns, or public goods. It’s a model that allows real sustainability and incentive alignment over time.

That’s why so many new ecosystems are choosing to build L2-first. It’s not just about technical architecture. It’s about economic design.

L1s Are the Mainframes of Web3

Here’s a simple mental model: Layer 1 blockchains are the mainframes of crypto.

In the early internet era, if you wanted to run a serious application, you bought a mainframe. You maintained the hardware. You wrote your own networking stack. You were responsible for uptime, security, performance — everything.

It was powerful, but expensive.

That’s what running an L1 looks like today. You need your own consensus. Your own validator set. Your own token incentives to secure the network. And to keep the system live and secure, you’re often spending millions each year.

In Celo’s case, they were spending 4–6% of annual token emissions — roughly $15M to $25M per year — just to maintain baseline security and liveness.

That’s not unusual. Ethereum does it. Solana does it (at even larger scale). Every independent L1 pays that cost. But what’s important is: that cost doesn’t scale down. If you’re a smaller chain, it’s often a disproportionate burden.

L2s Are Hosted Servers — Same Power, Lower Cost

Now imagine instead of running a mainframe, you switch to a hosted server.

You still control your environment. You can customize how your chain works. You still have sovereignty over execution. But you don’t have to secure the physical box yourself.

That’s what becoming an L2 on Ethereum looks like.

Celo, as an L2, will still provide the same user experience. But now, the heavy lifting on security — fraud proofs, consensus, base-layer finality — is handled by Ethereum. The cost of maintaining the chain drops dramatically.

Instead of $20M per year on security, the cost is now just state fees and data availability — which can be optimized further using compression and alternative DA layers (Celo choose @eigen_da).

Why This Is a Strategic Masterstroke by Ethereum

This isn’t just about Celo. This is about Ethereum’s long-term strategy finally starting to click into place.

Ethereum is no longer trying to be the “one server to rule them all.” That vision — of a single dominant chain — has already been proven false in every era of computing: Web1, Web2, and now Web3.

Instead, Ethereum is becoming the base layer other chains can build on — offering security, decentralization, and interoperability as a service.

Yes, it looks like cannibalization at first. Ethereum is reducing its L1 “premium.” But in reality, it’s capturing a much bigger market — by being the foundation others rely on.

You can die on the hill that there will only be 1 server or help build the next billions of them.

The same way no one runs their own mainframes anymore, in the future, very few projects will run their own L1s.

They’ll run hosted servers. They’ll become L2s.

And they’ll do it on Ethereum.

The Inevitable Gravity Toward Efficiency

As projects face market pressure to reduce costs and increase revenue, they’ll come to the same conclusion Celo did:

“Why spend tens of millions to secure your own chain when Ethereum offers stronger security for less?”

It might not happen overnight. But it will happen — because economics always win.
