Otra red basada en Ethereum sin futuro 🤷

[Relay @RelayProtocol]

We’re aware of reports of tokens disappearing from wallets after purchase on Robinhood Chain.

There’s been an increase in scam tokens designed to remove themselves after purchase. If you bought one, the funds you spent are unfortunately gone. We’re blocking these tokens as they show up and verifying safe ones.

Importantly, this is not a wallet compromise. Your private keys and other balances are untouched — nothing beyond the scam token purchase itself is at risk.

Reminder: anyone can list a token. Stick to tokens verified by us or another trusted source.

SuperTeam en #Argentina vamaaaaaa!!! 🚀🚀

[Superteam Argentina @SuperteamAR]

Some days mark the beginning of something bigger.

210 years ago, Argentina declared its independence.

Today, a new chapter begins for Solana in Argentina.

After two years of building this community from the ground up, our talent finally has a home.

A place for builders, founders and dreamers ready to grow, get support, and build for the world.

Welcome to Superteam Argentina.

Solana is down.

Yeah, down to breaking another all-time record. 😄

June 2026 officially became the strongest month in the network's history, with an incredible 3.8 billion transactions processed across the ecosystem.

The number is impressive on its own, but what really stands out is the trend. Every year, the network is handling more activity, serving more users, and proving that its infrastructure can support growth at an entirely different scale.

No single update creates a milestone like this.

It comes from years of improving performance, expanding the ecosystem, and making it easier for developers to build products that people genuinely use.

And it's another reminder that real adoption is measured in activity, not headlines.

Se viene "Lean Ethereum", una serie de profundos cambios en esa blockchain que será reescrita de cero y todos sus componentes cambiados para prepararla para un mundo post-quantum 🤯

[vitalik.eth @VitalikButerin]

Two weeks ago, Ethereum researchers met in Berlin to continue charting the protocol's long-term trajectory, following along discussions with client teams in Svalbard in April.

The updated strawmap is at https://t.co/9e2AQ6rhz6, and I attached a picture of it to this post.

My own high-level takeaways:

* "Lean Ethereum" is not a single one-shot upgrade, it is a collection of improvements that will come online to the Ethereum network over the course of three or four years. But make no mistake, this IS the third major iteration of Ethereum in the same way that the Merge was the second. Almost every major piece of the protocol will be replaced:

- Verification through recursive STARKs, rather than direct re-execution. Recursive STARKs become an enshrined first-class core component of the protocol
- Replacing everything quantum-vulnerable with quantum-safe alternatives
- Consensus: decoupled available chain and finality, one or two-round finality. Theoretically optimal security properties, simpler than today, and faster than today
- Multidimensional gas
- State: not just tree structure, but what *types* of state are available
- Changes to client architecture
...

At the same time, simplification, cleanup and future-proofing. And this will all be done in a way that minimizes disruption to existing application. We've done this before (the Merge), we can do it again.

* H-star (aka Hegota) is probably Ethereum's last thematically "pre-Lean" fork. Starting from I-star, most of everything we do will have a very strong "Lean" feel to it in one way or another.

* Privacy is no longer an afterthought, it is a first class goal. When designing Frames, the mempool, additions to the state tree, we explicitly ask the question "okay, how do quantum-safe, intermediary-free privacy protocol transactions go through this, and what is the overhead?"

* Formal verification of everything for security.

* FV also makes us much more comfortable with canonicalization (having pieces of the protocol that are directly defined as a piece of bytecode expressed in some language). evm-asm is being written in part to become a canonical proof system for the EVM.

* Quantum safety has shifted up a LOT in priority. This adds a lot of work (eg. finalizing a quantum-safe blobs design has become urgent; this work has already been ongoing for months)

* Probably the single most disruptive part of the plan is the changes to state. There is growing consensus around leaving present-day-style "dynamic state" mostly unchanged, but scaling it only a medium amount, and adding new types of state that are more scalability-friendly (eg. no need for builders to sync/store all of it) but more restrictive, and that will scale a large amount.

eg. possible Ethereum in 2030: 2 TB of present-day-style (dynamic) state, and 100 TB of new-style (scalable but restrictive) state

This "new-style" state would work very well for ERC20s, NFTs, many defi use cases, but not eg. highly "central" objects like Uniswap contracts, or onchain order books, or other complex things (which are crucial for Ethereum but which only take up a small percentage of state)

Hence, it will not be *necessary* to rewrite any apps, but it will be *very cost-effective* to eg. rewrite an ERC20 token into a newer design that uses a new type of UTXO storage that is currently being explored, so that it will have >10x lower txfees.

Design of these new state types (current ideas: keyed nonces, ring buffers, UTXOs, statically accessible state, temp state) is an area where we will need a lot of feedback from application developers (incl. privacy-friendly application developers) and probably several rounds of rethinking and iteration.

* In the context of a much larger total state size, we need to figure out the incentive issues around who stores this state and what motivates them to. Even saying "each node stores 1%" is not good enough - why do they store that 1% and why are they willing to serve it? This is being elevated as a first-class research area.

* Ethereum will need to have a "VM" other than EVM in one form or another - at the very least, we need something like leanISA for recursive STARKs - and the gains are large in exposing it to users so that we support programmable privacy and better scalability. Right now, the most likely contenders are leanISA and RISC-V.

My own ideal is that in this world, we adjust the protocol so that the EVM becomes a high-level-language compiler-level feature, and the protocol only "sees" RISC-V / leanISA directly. But this is still far away.

* Gas limit increases, blob increases and slot time decreases will happen many times over the next ~5 years. We expect a large gas limit increase with Glasterdam. Each step of increased scale or decreased slot time is a matter of getting to the point where it is safe to do it, which comes from a combination of client optimization and protocol changes.

Ethereum is CROPS.

Ethereum is scaling.

Ethereum is reinventing itself.

Onward.

Ornith 1.0 32B🦜 vs GLM5.2 🐲

i ran Ornith 1.0 32B locally on my Mac M2 Max (~60 tok/s) against GLM-5.2 on the same 5 animation tasks:

- burning paper
- paper slice
- bubble wrap
- zipper opening
- mechanical watch

as expected GLM-5.2 wins on quality, but Ornith is surprisingly competitive for a model running entirely on-device.

the gap is smaller than I expected

Hermoso recordatorio para alguien que apenas algunos conocen, pero que hace que Internet funcione hoy, en una enorme proporción, gracias a su software 😍

[Spencer Baggins @bigaiguy]

A French engineer who lives quietly in Paris has spent 30 years writing software that the entire internet now runs on without knowing his name.

He wrote the code that streams every YouTube video, every Netflix show, every TikTok clip. He wrote the code that runs the virtual servers underneath AWS, Google Cloud, and Microsoft Azure. He calculated more digits of pi than anyone in history. He has no Twitter. He has no marketing. He just keeps shipping.

His name is Fabrice Bellard.

Here is the story, because almost nobody outside the systems programming world knows what one man has built.

Fabrice was born in 1972 in Grenoble, France. He studied at École Polytechnique, the top French engineering school. He never went to Silicon Valley. He never built a startup empire. He just wrote code.

In 2000 he started a project called FFmpeg, an open-source multimedia framework for encoding, decoding, and streaming video. He was 28. The project did one thing nobody else had done well. It handled every video and audio format that existed, in one library, on every operating system. He led it himself for years.

Today FFmpeg is the invisible engine of the internet. YouTube uses it. Netflix uses it. VLC uses it. Chrome and Firefox use parts of it. Every Android phone, every iPhone, every smart TV, every video editing tool you have ever touched runs FFmpeg somewhere underneath. If you have watched a video on a screen in the last 20 years, Fabrice's code processed it.

He was not done.

In 2003 he started QEMU, a machine emulator and virtualizer. He wrote it solo until version 0.7.1 in 2005. QEMU lets you run any operating system on any other operating system. It became the foundation of modern virtualization. KVM, the Linux kernel hypervisor, runs on top of QEMU. Every major cloud provider, AWS, Google Cloud, Microsoft Azure, IBM Cloud, runs virtual machines on infrastructure built around it. The Quick Emulator is the most cited piece of cloud infrastructure code on Earth.

He kept going.

In 2001 he won the International Obfuscated C Code Contest with a small C compiler that grew into TCC, the Tiny C Compiler. TCC can compile and boot a Linux kernel from source in under 15 seconds. In 2004 he calculated the most digits of pi ever computed at the time, using a personal desktop computer and an algorithm he derived himself called Bellard's formula. In 2011 he wrote a complete PC emulator in pure JavaScript that runs Linux in your browser, a project called JSLinux that engineers still cannot believe is real.

In 2019 he released QuickJS, a small but complete JavaScript engine that fits where V8 cannot. In 2021 he released NNCP, a neural network based lossless data compressor that immediately took the lead on the Large Text Compression Benchmark.

Then he turned his attention to large language models. He built TextSynth Server, a web server with a REST API for running LLMs locally. He released ts_zip and ts_sms, compression utilities that use language models to compress text and short messages at ratios traditional algorithms cannot reach. He released TSAC, a very low bitrate audio compression system. In December 2025 he released Micro QuickJS, a new JavaScript engine for microcontrollers, separate from QuickJS, designed for environments with almost no memory.

Fabrice co-founded a telecom company called Amarisoft in 2012, where he serves as CTO. Amarisoft builds 4G and 5G base station software used by carriers and labs around the world. He has been running it for over a decade while continuing to ship personal projects from his own home page at bellard dot org

He has no Twitter. He has no Instagram. He gives almost no interviews. His personal website is a flat list of projects with no styling, no fonts, no marketing copy. Just titles and links.

A quiet French engineer who never moved to Silicon Valley wrote the code that quietly runs the internet.

He is still shipping.

OTRO KIOSKO QUE SE VA… HOY, LA BUROCRACIA PARA IMPORTAR PILAS. Puede parecer una boludez, pero resultaba un impedimento para la importación y un sobrecosto para relojes, juguetes, controles remotos, calculadoras, linternas, teclados inalámbricos y miles de productos de uso cotidiano. Como toda barrera, tiene su “cara linda”: el supuesto objetivo de evitar la comercialización de productos con niveles peligrosos de mercurio, cadmio y plomo. Pero la realidad era un lobby atrás que encarecía el precio de esos productos.

Por eso, hace unos meses, con el Decreto Delegado 431/25 habíamos empezado a desmontar esa parafernalia. Pensemos en una pila botón fabricada en Japón para un reloj. Se vende en Europa, Estados Unidos y Japón. Fue ensayada por laboratorios especializados, certificada por organismos reconocidos internacionalmente y utilizada en millones de productos alrededor del mundo. Sin embargo, para venderse en Argentina había que volver a certificarla localmente. Y volver a hacerlo para cada modelo. Y volver a hacerlo al año siguiente. Para juguetes, por ejemplo, era una gran barrera de entrada y además un gran negocito para los certificadores de pilas (acá la política industrial más exitosa ¡fue el de la industria de las certificaciones!)

El Decreto 431/25 introdujo un cambio conceptual en línea con todo lo que venimos haciendo: si una pila ya acreditó su conformidad ante organismos técnicos reconocidos internacionalmente, Argentina reconoce esa acreditación sin obligar a repetir todo el procedimiento desde cero. La Resolución Conjunta 1/26 firmada por el Secretario de Coordinación Productiva @PALavigne83 y el Secretario de Turismo y Ambiente @danielscioli reglamenta y completa esta reforma.

Desaparecen las autorizaciones previas para importar y comercializar y el cumplimiento se acredita mediante una declaración jurada de conformidad (donde se adjunta un informe de ensayo o se acredita la certificación internacional). Un paso más en el proceso de libertad económica que nos pide el presidente @JMilei. VLLC!

[The White Whale @WhiteWhaleLabs]

Dear Solana:

Solana is my favorite blockchain to transact on. It is still one of my favorite assets to trade. And when price is attractive, I still think there is a good case for accumulating it.

But I am less bullish on SOL’s next-cycle price targets than I was last time.

Last cycle, while everyone was calling for $500+ SOL, I publicly said I planned to be out before $250. Solana’s ATH came earlier than BTC and much of the market, but that call ended up being pretty damn close.

This time, unless I see a real fundamental shift, I will probably be lowering my targets. As things stand now, I would likely be out before $200 next cycle.

That is not because I hate Solana. I don’t.

But love is not a sound investment thesis.

The reasons are pretty straightforward.

Pump fun has historically made up a meaningful chunk of Solana volume, and I believe the pump (and broader memecoin casino) meta is dying. Maybe it evolves. Maybe something replaces it. But pretending that was not a significant driver of activity feels dishonest.

Solana DeFi has also taken a serious hit. A lot of Solana DeFi was tied into Drift, and the damage there impacted dozens of protocols. It hurt the broader perception of Solana DeFi.

Then there is the capital markets side.

A lot of Solana DATs were formed at some of the worst possible price points, then unwound, restructured, or de-risked at some of the worst possible price points.

CT forgets everything in 72 hours but institutional capital does not.

If a bunch of institutions got dragged into Solana exposure near the highs, then unwound for losses, that leaves a mark. It does not mean they will never touch SOL again. But it does mean the next wave of institutional appetite may not be as easy, clean, or deep as people assume.

Then there is the cultural layer.

Solana feels disjointed right now. Some of the most prominent Solana voices have spent an incredible amount of time relentlessly shilling an entirely different blockchain. Yes, ZEC is it's own Layer 1.

It does not exactly scream focus on Solana itself. It reads as devs thinking their bag is cooked and so they start pumping their next bag.

Only now does there finally seem to be real traction around addressing the inflation issue, which should have been more meaningfully a long time ago.

But what really read as desperation to me was the @PhoenixTrade push. That moment actually influenced my vision more than any of the others.

Look, I have traded over $5B in perps across various protocols. I have tested or used almost every “perp DEX” worth testing. And Phoenix is about as basic as it gets.

Yes, the engineering under the hood is interesting. Fine. Mad respect to the builders.

But traders do not ultimately care about engineering.

They care about three things:

Does it work?

Can I make money there?

Is it safe?

And right now, the best Solana-adjacent perps venue is @pacifica_fi . I say Solana-adjacent because it is mostly the stables on-ramp and Solana TVL. It is not generating massive activity for the Solana network itself. And even Pacifica has already talked about building its own L1. (A decision I'm skeptical about, even as a fan)

My exact reaction to the huge marketing push on one of the most basic perp dexs I've ever traded on was: they are so very desperate for something to gain traction on Solana it actually scares me.

Solana talks a lot about what it wants to be when it grows up. And to be clear, the vision is compelling. The ambition is real. The talent is definitely real.

But ambition is not maturity.

Every kid wants to be a doctor, an astronaut, or a superhero when they grow up.

I care more about what something actually is than what it says it wants to become.

So what is my favorite new blockchain?

Solana.

Because you can still love something and still be rational about it.

this is just the most ridiculous AI application i've ever seen lol

a Peter Thiel-backed startup that makes AI collars for cows is now worth $2 billion

and the more I read about it the cooler it gets. here's how it works:

every cow wears a solar-powered collar that talks to a network of radio towers and an app on the farmer's phone

instead of building physical fences, the farmer draws the fence on a map in the app, and the collar keeps each cow inside that invisible line using GPS

when a cow drifts toward the edge, the collar plays a sound to steer her, and a gentle vibration tells her which way to go.

it's like how a car beeps as you back up toward a wall

the cows learn the cues in a few days

so now a rancher can move an entire herd to fresh grass by sliding the fence on a map, without driving out to open a single gate

and that same collar is reading each cow's body the whole time.

it takes five readings per second on every animal, so the AI can catch a cow that's sick, injured, ready to breed, or about to give birth before a person would ever notice walking the field

so it's basically like WHOOP for cows too lol

and they gave the AI behind it the perfect name: the Cowgorithm

it's been trained on more than 7 billion hours of real cow behavior, which is why Halter calls the data its real asset and moat.

they know what a normal cow looks like better than anyone, so they can flag the odd one out instantly

it's already on more than 1M cattle across New Zealand, Australia, and a bunch of US states.

California even used it on public land to graze cattle in patterns that clear dry brush and slow down wildfires

costs about $5 to $8 per cow per month

a job that used to mean barbed wire, gates, and driving the fields all day is now mostly 1 person on their phone

Extremely rare 'White Auroras' spotted over Norway.

The sky over Norway just did something it almost never does.
Photographers chasing the northern lights got the shock of their lives.

Instead of the usual greens and purples dancing overhead, the auroras turned ghostly white.

Pure. Pale. Almost glowing.

It's one of the rarest aurora displays on Earth.

Scientists say white auroras happen when multiple aurora colors overload the human eye at once, blending together until they appear colorless. The brain simply can't process all the wavelengths firing at the same time, so it surrenders and sees white.

Most aurora chasers go their entire careers without witnessing it.
Norway just delivered the impossible.

Cameras across the Arctic captured the eerie phenomenon lighting up the night like frozen lightning, leaving even seasoned skywatchers speechless.

Some called it otherworldly.
Others said it looked like the sky was bleeding light.

And for a few unforgettable minutes, the heavens above Norway turned into something nobody had ever seen before.
