CHALLENGE ACCEPTED. Not a challenge related to drama farmers saying "L2s bad, Ethereum dumb." But instead the challenge of creating a modular L2 Stack that supports and enables customization and the full spectrum of decentralization. And you know -- we're already closer to that reality than you might think. We already have chains built using the OP Stack at Stage 0, Stage 1, and Stage 2. We already have a custom builder API which enables different sequencing rules. You can use ZK proofs you can use fault proofs. It's honestly overwhelming and yet it's just the beginning. But I don't want bull posting to get in the way of the reality. We still have a long way to go to realize the Ethereum vision: * Default withdrawal window from Ethereum is a week! This is insane and a priority. We gotta get that down to an hour or try 10 minutes?! * Stage 2 isn't production ready. We've got a lot of proofs but nothing nearly secure enough to power a major bridge. Aside: I've been advocating for a native eth precompile for rollups for literally almost a decade. Ever since Vitalik posted this: github.com/ethereum/EIPs/… . I guess L1 takes a while to ship features too 😄 just playin ❤️ excited to support it * We still don't have block explorers and developer tooling to enable cross chain applications which makes ecosystem lock-in much more powerful. It's critical that we continue to push the frontier of what is possible and also call out those who don't. There are a few "just a separate L1 with a bridge"s out there. But that's why we just gotta keep our heads down and ship real software. It's a new era. We're bringing Ethereum to the masses with a stack that fits what they need. And we're cooking on gas rn. Alright I gotta get back to the TUI

There have recently been some discussions on the ongoing role of L2s in the Ethereum ecosystem, especially in the face of two facts: * L2s' progress to stage 2 (and, secondarily, on interop) has been far slower and more difficult than originally expected * L1 itself is scaling, fees are very low, and gaslimits are projected to increase greatly in 2026 Both of these facts, for their own separate reasons, mean that the original vision of L2s and their role in Ethereum no longer makes sense, and we need a new path. First, let us recap the original vision. Ethereum needs to scale. The definition of "Ethereum scaling" is the existence of large quantities of block space that is backed by the full faith and credit of Ethereum - that is, block space where, if you do things (including with ETH) inside that block space, your activities are guaranteed to be valid, uncensored, unreverted, untouched, as long as Ethereum itself functions. If you create a 10000 TPS EVM where its connection to L1 is mediated by a multisig bridge, then you are not scaling Ethereum. This vision no longer makes sense. L1 does not need L2s to be "branded shards", because L1 is itself scaling. And L2s are not able or willing to satisfy the properties that a true "branded shard" would require. I've even seen at least one explicitly saying that they may never want to go beyond stage 1, not just for technical reasons around ZK-EVM safety, but also because their customers' regulatory needs require them to have ultimate control. This may be doing the right thing for your customers. But it should be obvious that if you are doing this, then you are not "scaling Ethereum" in the sense meant by the rollup-centric roadmap. But that's fine! it's fine because Ethereum itself is now scaling directly on L1, with large planned increases to its gas limit this year and the years ahead. We should stop thinking about L2s as literally being "branded shards" of Ethereum, with the social status and responsibilities that this entails. Instead, we can think of L2s as being a full spectrum, which includes both chains backed by the full faith and credit of Ethereum with various unique properties (eg. not just EVM), as well as a whole array of options at different levels of connection to Ethereum, that each person (or bot) is free to care about or not care about depending on their needs. What would I do today if I were an L2? * Identify a value add other than "scaling". Examples: (i) non-EVM specialized features/VMs around privacy, (ii) efficiency specialized around a particular application, (iii) truly extreme levels of scaling that even a greatly expanded L1 will not do, (iv) a totally different design for non-financial applications, eg. social, identity, AI, (v) ultra-low-latency and other sequencing properties, (vi) maybe built-in oracles or decentralized dispute resolution or other "non-computationally-verifiable" features * Be stage 1 at the minimum (otherwise you really are just a separate L1 with a bridge, and you should just call yourself that) if you're doing things with ETH or other ethereum-issued assets * Support maximum interoperability with Ethereum, though this will differ for each one (eg. what if you're not EVM, or even not financial?) From Ethereum's side, over the past few months I've become more convinced of the value of the native rollup precompile, particuarly once we have enshrined ZK-EVM proofs that we need anyway to scale L1. This is a precompile that verifies a ZK-EVM proof, and it's "part of Ethereum", so (i) it auto-upgrades along with Ethereum, and (ii) if the precompile has a bug, Ethereum will hard-fork to fix the bug. The native rollup precompile would make full, security-council-free, EVM verification accessible. We should spend much more time working out how to design it in such a way that if your L2 is "EVM plus other stuff", then the native rollup precompile would verify the EVM, and you only have to bring your own prover for the "other stuff" (eg. Stylus). This might involve a canonical way of exposing a lookup table between contract call inputs and outputs, and letting you provide your own values to the lookup table (that you would prove separately). This would make it easy to have safe, strong, trustless interoperability with Ethereum. It also enables synchronous composability (see: ethresear.ch/t/combining-pr… and ethresear.ch/t/synchronous-… ). And from there, it's each L2's choice exactly what they want to build. Don't just "extend L1", figure out something new to add. This of course means that some will add things that are trust-dependent, or backdoored, or otherwise insecure; this is unavoidable in a permissionless ecosystem where developers have freedom. Our job should make to make it clear to users what guarantees they have, and to build up the strongest Ethereum that we can.
