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.

@yuki_sat お、おかえりなさーい！ひと足先に日本に帰ってました！

ドイツには13年間暮らしました。ほとんどベルリン。改めて振り返ると13年は長い。これ以上いたらさらに腰が重くなると思い、やる気が出たタイミングでExitしました。帰国後やりたいことの準備も含めて1年がかり。ようやく移動できて今は一安心です

日本に引っ越しました。12月でも紅葉が楽しめるのは想像外でした 久々の日本での生活、ドキドキワクワク☺️

We are investigating a potential security incident in our AWS infrastructure and have therefore taken Lisk Portal offline out of caution. Note that we have not received any reports of any malicious activity related to the Lisk Portal so far.

Lisk x United Nations 🇺🇳 We’re excited to announce we’ve joined ScaleX, the @UN's new deep-tech accelerator led by @UNIDO, as its first partner. Together, we are launching the Lisk x ScaleX Web3 Incubator for founders in emerging markets to run real pilots with governments and industry 🧵

Behind closed doors, big things have been happening at Lisk. Today, we can finally start talking about one of them. 🚀 🌍💡 Last week in Riyadh 🇸🇦, our Head of Investments, @gideongreaves, attended the United Nations convention where the @UN officially launched ScaleX; a global accelerator helping startups run real pilots with governments and enterprises. 🏛️📈 ScaleX is led by @UNIDO, which is the United Nations Industrial Development Organization. A UN body responsible for advancing industrial growth and economic development worldwide. And here’s the part that matters: 👉 Lisk was announced as the first organization partnering with UNIDO on ScaleX. Together, we are creating the Lisk x ScaleX Web3 Incubator. A UN-supported initiative focused on applying decentralized technologies to industrial and supply-chain challenges in Emerging Markets. 🌐🤝 This partnership positions Lisk at the center of a global initiative connecting tech, industry, and sustainable development and aligns directly with our Mission in Emerging Markets. Governments, VCs, and ecosystem leaders were present, including representatives from Barbados 🇧🇧, Georgia 🇬🇪, and Slovenia 🇸🇮, many of whom expressed interest in future collaboration. A major milestone for Lisk and the beginning of a powerful new chapter for Web3 adoption. 💥

That’s one of the reasons why we choose to move to Ethereum and use op stack years ago! The infra won’t be the moat but the ecosystem, apps, AIs and humans on and off the chain, is the main differentiator. Building that takes time, but we are in the right direction

We are investigating a potential DNS hijacking. Please do not use our primary domain as we investigate.

You can't just launch a project nowadays and expect market to care. Oversaturation of tokens, lack of actual product-market fit and real business models, has led to people questioning their reality and having a reality check smack in their face about what is really happening in this industry. It's time for the entire industry to wake the f*ck up and return to fundamentals.

1/ Since a lot of people are waking up to see their perps positions closed and wondering what the hell “Auto-Deleveraging” means, here’s a quick and dirty primer. What is ADL? How does it work? And why does it exist?

Today, the Lisk EMpower Fund goes live — a $15M venture fund backing founders in Africa, Southeast Asia, and Latin America. 🌍 Our mission: close the capital gap and support proven products on their path to global scale. 👉 lisk.com/fund The opportunity ahead 🧵

🚨 There’s a large-scale supply chain attack in progress: the NPM account of a reputable developer has been compromised. The affected packages have already been downloaded over 1 billion times, meaning the entire JavaScript ecosystem may be at risk. The malicious payload works by silently swapping crypto addresses on the fly to steal funds. If you use a hardware wallet, pay attention to every transaction before signing and you're safe. If you don’t use a hardware wallet, refrain from making any on-chain transactions for now. It’s still unclear whether the attacker is also stealing seeds from software wallets directly at this stage. Excellent report here: jdstaerk.substack.com/p/we-just-foun…

JPYC盛り上がったてるけどステーブル事業って、銀行とかが大きく出してきた時一気に持ってかれないのかな？🤔

セキュリティ担保とエコシステムを作るコストを考えると今だと資金が数100億単位でないとL1作るのは難しいだろうなー そのコストあるならL2に全力投球した方が業界全体としては良さそう
