We are told that Layer 2s are the final frontier of Ethereum scaling. That they will bring millions of users to decentralized finance, reduce fees to fractions of a cent, and make the blockchain vision of “world computer” a reality. VCs are pouring billions into rollup ecosystems, and every week a new project announces its own OP Stack chain or ZK-powered L2. The narrative is intoxicating: scalability is solved, we just need adoption.
But in my three years as a protocol PM for a Seattle-based L2 scaling solution, I have watched this narrative warp into something dangerous. The bull market of 2024-2025 has created a gold rush mentality where teams deploy chains faster than they can audit them. And the real winner isn’t the best technology — it’s the one that captures the most developer mindshare. I have sat in institutional meetings where decision-makers ask “Which rollup should we use?” and the answer is always “It depends on your exit strategy, not your values.”
Decentralization is a verb, not a noun. And right now, the verb is being conjugated in a very specific way: “We fork, we deploy, we raise.”
Context: The Great L2 Forking Frenzy
Let me give you the numbers. As of Q2 2025, there are over 120 active Layer 2 chains on Ethereum, according to L2Beat. Of those, approximately 70% are built on the OP Stack — Optimism’s modular rollup framework. Another 20% use various ZK rollup stacks (zkSync, StarkNet, Scroll, Polygon zkEVM), and the remaining 10% are custom or specialized solutions (Arbitrum Orbit, Cartesi, etc.).
The OP Stack’s dominance is not accidental. It offers a “one-click deployment” experience: fork the repository, configure your tokenomics, and launch a chain. The documentation is excellent, the community is active, and the scaling logic is battle-tested through Optimism’s own mainnet. For a team that wants to launch quickly and capture users in a bull market, the OP Stack is the path of least resistance.
But here’s the problem: quick deployment does not mean long-term viability. I have personally reviewed the architecture of eight OP Stack chains in the past six months. Three of them had no custom fraud proof system — they simply copied the default settings. Two used the same sequencer set as Optimism, meaning they have zero sovereignty. One even forgot to change the chain ID and accidentally broadcast transactions to the wrong L2. These are not edge cases; they are the norm in a market that rewards speed over substance.
The Core: Why OP Stack Is Winning (And Why It Might Not Matter)
The technical argument for OP Stack is straightforward: it provides a shared security layer through the Superchain vision. Chains built on the OP Stack can eventually share liquidity, sequencing, and governance. In theory, this creates a unified network of interoperable L2s that can scale Ethereum horizontally. In practice, most teams are deploying isolated chains that do not benefit from any of these synergies because the Superchain infrastructure is still in development.
Let me contrast this with the ZK Stack. ZK rollups are technically superior in almost every dimension: instant finality (instead of 7-day challenge periods for optimistic rollups), lower overhead costs for verification, and stronger privacy guarantees. zkSync Era and StarkNet have demonstrated that ZK proofs can be generated for general-purpose smart contracts at scale. Yet ZK stack chains account for only 20% of new deployments. Why?
The answer is not technical — it is sociological. Building a ZK rollup requires hiring developers who understand arcane mathematics and circuit design. The tooling is immature; debugging a ZK circuit can take weeks instead of hours. The documentation is written by researchers for researchers. In a bull market, teams want to ship, not research.
I recall a conversation with a founder in January 2025. He told me: “We chose OP Stack because we could get a testnet live in two weeks. With zkSync, it would take two months, and by then the narrative would have moved to something else.” He was right. The bull market punishes deliberation. It rewards speed, even if that speed comes at the cost of decentralization or security.
But here is the contrarian angle: The very forces that make OP Stack win today are the forces that will lead to a fragmentation crisis within 18 months. Think about it. If every chain is easy to deploy but hard to migrate, we end up with hundreds of isolated L2s with no meaningful interoperability. Users will have to bridge tokens between ten different rollup ecosystems, each with its own security model, sequencer trust assumptions, and governance token. The UX will become a nightmare — worse than the current Ethereum Layer 1.
I have seen this movie before. During DeFi Summer 2020, we had a Cambrian explosion of fork farms on Uniswap and SushiSwap. Everyone launched a shitcoin with a funny name and a double-digit APR. Within six months, 90% of those farms were ghost towns, and the remaining liquidity consolidated on a few dominant protocols. The same consolidation will happen in the L2 space. The only question is which chains survive the culling.
The bear market of 2022-2023 was a crucible that forced teams to focus on fundamentals. The current bull market is rewarding hype again. I fear that we are building a house of cards: beautiful on the outside but hollow inside.
The Contrarian: What If the Winner Is Not Ethereum?
While the crypto community obsesses over which L2 stack will dominate, a larger threat looms. Bitcoin Layer 2s have entered the conversation with increasing volume. Projects like Stacks, RSK, Lightning Network, and newer entrants like Bison Labs and Nomic are positioning themselves as scaling solutions for the Bitcoin ecosystem. The narrative is powerful: “Bitcoin is digital gold, but it also needs programmability. Let’s bring DeFi to Bitcoin.”
I want to be blunt: 90% of so-called Bitcoin L2s are Ethereum projects rebranding for hype. They fork the EVM, run a sidechain, and call it a “Bitcoin Layer 2” because they deposit BTC as collateral. The real Bitcoin community does not acknowledge them. They violate the core ethos of Bitcoin: minimalism, trust minimization, and maximal decentralization.
I attended a conference in Austin in April 2025 where a presenter claimed their project was “the first true Bitcoin L2.” I raised my hand and asked: “Does your bridge rely on a multisig of three validators?” He said yes. I asked: “Then how is this different from a federated sidechain?” He did not have an answer.
The honest truth is that Bitcoin does not need L2s in the way Ethereum does. Bitcoin’s utility is as a store of value and settlement layer. Attempting to turn it into a smart contract platform introduces attack surfaces and compromises its security model. I have spent many nights thinking about this — maybe I am wrong. But my experience in the 2022 bear market, when I wrote “Privacy as a Human Right in the Trustless Era,” taught me that narrative can be more powerful than reality. The market will decide, but I hope it decides based on technical truth, not marketing budgets.
Takeaway: The Real Battle Is for Values, Not Technology
My time as a protocol PM has taught me that the most important variable in decentralized systems is not transaction throughput or finality — it is alignment. Chains that align with the values of their users and developers will survive. Chains that are built solely for speculation will die when the music stops.
I think back to the “Ghost Protocol” days of 2022, when I buried myself in zero-knowledge proofs to find meaning in a market that had lost its soul. That experience showed me that bear markets are the best time to build because the noise is gone. Now, in the bull market, the noise is deafening. Every day a new L2 announces a raise. Every week a new Bitcoin L2 fork appears. Every month a new narrative cycle begins.
But underneath all that noise, the same truth holds: decentralization is a verb, not a noun. It requires constant work, constant vigilance, and constant alignment. The teams that treat L2 deployment as a verb — something they actively maintain and improve — will be the ones that matter in the next cycle.
I do not have a conclusion to offer. I can only pose a question: Are we building the infrastructure for a truly decentralized world, or are we just repeating the same mistakes of centralized finance under a new brand? The answer will become clear when the next bear market arrives. And it will arrive.
Until then, I will keep writing, keep auditing, and keep asking the uncomfortable questions. That is the only way to ensure that when the hype fades, what remains is something worth keeping.
