Always underestimates how long a trade will take. Slow. :(

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: https://t.co/9jy6v1X6Fw and https://t.co/gZmu3YjebM ). 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.

@DecideMadrid no me llega el sms para verificar la cuenta. Me podéis dar alguna solucion??.

Gracias.

@canalsurcordoba @pasoapasocsr @CanalSurRadio Y para descargarlo??

[Laupome® ツ✌🏼 @PlanFallacy]

@canalsurcordoba @pasoapasocsr @Gentedepaz @agrupacioncor @procesionescord Y va a estar disponible para descargarlo y llevarlo en el móvil?

[Laupome® ツ✌🏼 @PlanFallacy]

@minube para cuando tendremos novedades de la Quedada Viajera de fitur??

[Laupome® ツ✌🏼 @PlanFallacy]

@pasoapasocsr Lo podemos obtener en PDF??

[Laupome® ツ✌🏼 @PlanFallacy]

@agrupacioncor Y no nos lo podemos descargar desde la web como otros años??

[Laupome® ツ✌🏼 @PlanFallacy]

@agrupacioncor para cuando estará el librito de los itinerarios??. Por cierto la nueva web no está actualizada en la parte de Hermandades. Recordad que la Hermandad de la Veracruz sale el Domingo de Ramos y no el Lunes Santo como pone en vuestra web…

[Laupome® ツ✌🏼 @PlanFallacy]

@EMTmadrid verguenza os tenía que dar que llevamos mas de 20 minutos esperando un 35 en la parada 594 y el que pasa no admite viajeros y el que viene munutos despues pues lleno… y luego nos dicen que cojamos el transporte público

[Laupome® ツ✌🏼 @PlanFallacy]

@minube Para cuando salen las entradas de la maravillosa Quedada de todos los años??

[Laupome® ツ✌🏼 @PlanFallacy]

@minube @minube habéis mandado los mails para las entradas del domingo??, es que a día de hoy no me ha llegado nada y no se si es porque no he sido afortunada o porque aún no se ha mandado

[Laupome® ツ✌🏼 @PlanFallacy]

@Mercadona me gustaría saber el motivo del cierre del Mercadona de la Avda. del Consuelo en Ciempozuelos ya que vivo al lado!

[Laupome® ツ✌🏼 @PlanFallacy]

@minube para cuando mas info sobre la quedada viajera??

[Laupome® ツ✌🏼 @PlanFallacy]

@minube Este año habrá la Quedada Viajera para Fitur??

[Laupome® ツ✌🏼 @PlanFallacy]

@pili71 @vodafone_es Desde un principio siempre pensé que era del cajetín de fuera pero parece ser que el técnico solo se empeñó en cambiarlo y no mirarlo.... al final tuvo que abrirse otra avería y finalmente era del cajetín, en fin así son los técnicos de impresentables

[Laupome® ツ✌🏼 @PlanFallacy]

@vodafone_es mañana será el tercer día q no tengo internet en casa. No puedo teletrabajar y tengo q desplazarme, ya he abierto la 2ª avería y ni cambiándome el router me funciona!!, por favor a ver si me lo solucionan pronto y miren bien, no puedo estar tanto tiempo sin internet

[Laupome® ツ✌🏼 @PlanFallacy]

@EMTmadrid tuvimos un accidente en el 35, mi madre fue afectada como viajera, la tuvieron que llevar al hospital por un traumatismo craneoencefálico. El conductor me dijo que iba a dar parte él y que tenía que llamar yo a la EMT?, que se hace en estos casos?

[Laupome® ツ✌🏼 @PlanFallacy]

@agrupacioncor cuando va a salir los itinerarios de esta semana santa???

[Laupome® ツ✌🏼 @PlanFallacy]

@vodafone_es quisiera confirmar si este teléfono os pertenece 912777442. No se si me han llamado por lo insatisfecha que estoy con vosotros y varias reclamaciones puestas que no me sirven para nada.
