New year new role 🚨 I’ve joined @ethereum as part of the Account & Chain Abstraction Team! This new chapter is deeply connected to a goal I’ve held: to positively impact 1 billion people in my lifetime. To me, Ethereum is the perfect place to make that happen.

@hiaubree @RoseParade I think this is the year I met you!! So cool to see where you are now

2023 was a crucial year of growth for me in this industry. After 6 months of being "on the ground" at crypto events and helping to collaborate on the first-ever DAO-funded parade float for the Pasadena @RoseParade, I ventured even further onto the event scene to talk to people about crypto and DAOs. At one of my first events of the year, @poapxyz let me take over half of their booth at @nft_paris to do interviews with people from our industry. This led to an interview with @jnbarrot, who at the time was the Minister Delegate for Digital Transition and Telecommunications in France. Going from daily Twitter Spaces and weekly Discord meetings for holders to talking with political leaders who had the power to push positive narratives in our industry is a moment I will never forget and one I've continued to build upon. Although I can look back on this interview and be critical about how I personally did and what I might have done differently, it doesn't change the opportunity that was given to me. This is what it looks like when a non-technical person lugs 2 suitcases of camera and podcast equipment around the world for a year and a half to shine a light on our industry. Storytelling has and always will be a major pillar in my life. Now, I get to do this from the viewpoint of someone who helps execute large-scale hackathons for @ethereum. I am forever grateful for the opportunity that was given to me on this day. This may be the end of an era, but I hold hope that there's a new era on the horizon for the POAP team. They have affected too many lives in this industry for that not to be the case. ❤️

$TAO TAO at $234. Biggest green volume candle in months just printed. The accumulation pattern I've been watching for 6 weeks looks like it's finally resolving to the upside. My first target is $267 — the 200 EMA. If we lose $220 — the setup is invalidated and I reassess. But personally... this is the chart I'm most bullish on right now. The halving is done. The supply is tightening. The smart money loaded at $160. We're just getting started.

@izgnzlz Good luck going forward 🚀 I’ve always been a big POAP fan and can’t wait to see what you guys do next

My dear compatriots, Decisive moments lie before us. The assistance that the President of the United States had promised to the brave people of Iran has now arrived. This is a humanitarian intervention, and its target is the Islamic Republic, its apparatus of repression, and its machinery of killing—not the country and great nation of Iran. However, despite the arrival of this assistance, the final victory will still be achieved by us. It is we, the people of Iran, who will finish this task in this final battle. The time to return to the streets is approaching. Now that the Islamic Republic is collapsing, my message to the country’s military, law enforcement, and security forces is clear: You have sworn an oath to protect Iran and the Iranian nation, not the Islamic Republic and its leaders. Your duty is to defend the people, not to defend a regime that has taken our homeland hostage through repression and crime. Join the nation and help ensure a stable and secure transition. Otherwise, you will sink with Khamenei’s ship and his crumbling regime. And my message to the President of the United States, President Trump, is this: The honorable people of Iran, despite the brutal repression and killings carried out by this regime, stood bravely for nearly two months. I now ask you to exercise the utmost possible caution to preserve the lives of civilians and my compatriots. The people of Iran are your natural allies and the allies of the free world, and they will not forget your assistance during the most difficult period of Iran’s contemporary history. And to you, my dear compatriots in Iran: In these sensitive hours and days, more than ever we must remain focused on our ultimate goal: reclaiming Iran. I ask you, for now, to remain in your homes and remain calm and safe. Stay alert and ready to return to the streets for the final action at the appropriate time, which I will communicate to you. Follow my messages through social media and satellite media. If disruptions occur in the internet and satellite broadcasts, I will remain in contact with you via radio. We are very close to final victory. I hope to be with you as soon as possible so that together we may reclaim Iran and rebuild it. Long live Iran. Reza Pahlavi

Introducing strawmap, a strawman roadmap by EF Protocol. Believe in something. Believe in an Ethereum strawmap. Who is this for? The document, available at strawmap[.]org, is intended for advanced readers. It is a dense and technical resource primarily for researchers, developers, and participants in Ethereum governance. Visit ethereum[.]org/roadmap for more introductory material. Accessible explainers unpacking the strawmap will follow soon™. What is the strawmap? The strawmap is an invitation to view L1 protocol upgrades through a holistic lens. By placing proposals on a single visual it provides a unified perspective on Ethereum L1 ambitions. The time horizon spans years, extending beyond the immediate focus of All Core Devs (ACD) and forkcast[.]org which typically cover only the next couple of forks. What are some of the highlights? The strawmap features five simple north stars, presented as black boxes on the right: → fast L1: fast UX, via short slots and finality in seconds → gigagas L1: 1 gigagas/sec (10K TPS), via zkEVMs and real-time proving → teragas L2: 1 gigabyte/sec (10M TPS), via data availability sampling → post quantum L1: durable cryptography, via hash-based schemes → private L1: first-class privacy, via shielded ETH transfers What is the origin story? The strawman roadmap originated as a discussion starter at an EF workshop in Jan 2026, partly motivated by a desire to integrate lean Ethereum with shorter-term initiatives. Upgrade dependencies and fork constraints became particularly effective at surfacing valuable discussion topics. The strawman is now shared publicly in a spirit of proactive transparency and accelerationism. Why the "strawmap" name? "Strawmap" is a portmanteau of "strawman" and "roadmap". The strawman qualifier is deliberate for two reasons: 1. It acknowledges the limits of drafting a roadmap in a highly decentralized ecosystem. An "official" roadmap reflecting all Ethereum stakeholders is effectively impossible. Rough consensus is fundamentally an emergent, continuous, and inherent uncertain process. 2. It underscores the document's status as a work-in-progress. Although it originated within the EF Protocol cluster, there are competing views held among its 100 members, not to mention a rich diversity of non-EFer views. The strawmap is not a prediction. It is an accelerationist coordination tool, sketching one reasonably coherent path among millions of possible outcomes. What is the strawmap time frame? The strawmap focuses on forks extending through the end of the decade. It outlines seven forks by 2029 based on a rough cadence of one fork every six months. While grounded in current expectations, these timelines should be treated with healthy skepticism. The current draft assumes human-first development. AI-driven development and formal verification could significantly compress schedules. What do the letters on top represent? The strawmap is organized as a timeline, with forks progressing from left to right. Consensus layer forks follow a star-based naming scheme with incrementing first letters: Altair, Bellatrix, Capella, Deneb, Electra, Fulu, etc. Upcoming forks such as Glamsterdam and Hegotá have finalized names. Other forks, like I* and J*, have placeholder names (with I* pronounced "I star"). What do the colors and arrows represent? Upgrades are grouped into three color-coded horizontal layers: consensus (CL), data (DL), execution (EL). Dark boxes denote headliners (see below), grey boxes indicate offchain upgrades, and black boxes represent north stars. An explanatory legend appears at the bottom. Within each layer, upgrades are further organized by theme and sub-theme. Arrows signal hard technical dependencies or natural upgrade progressions. Underlined text in boxes links to relevant EIPs and write-ups. What are headliners? Headliners are particularly prominent and ambitious upgrades. To maintain a fast fork cadence, the modern ACD process limits itself to one consensus and one execution headliner per fork. For example, in Glamsterdam, these headliners are ePBS and BALs, respectively. (L* is an exceptional fork, displaying two headliners tied to the bigger lean consensus fork. Lean consensus landing in L* would be a fateful coincidence.) Will the strawmap evolve? Yes, the strawmap is a living and malleable document. It will evolve alongside community feedback, R&D advancements, and governance. Expect at least quarterly updates, with the latest revision date noted on the document. Can I share feedback? Yes, feedback is actively encouraged. The EF Protocol strawmap is maintained by the EF Architecture team: @adietrichs, @barnabemonnot, @fradamt, @drakefjustin. Each has open DMs and can be reached at first.name@ethereum[.]org. General inquiries can be sent to strawmap@ethereum[.]org.

@dwr @gakonst @tempo @matthuang Congrats!

I'm thrilled to announce that I'm joining @tempo! Stablecoins are a generational opportunity and I'm excited to work with @matthuang, @gakonst and the rest of the team to make them mainstream.

Ethereum’s biggest mistake would be outsourcing trust at the exact moment it becomes hardest to reason about. Cross-chain execution is that moment! EIL lets users self-execute transactions cross-chain while preserving Ethereum’s trustless execution model. Why this matters 👇

TheDAO is back. BULLISH A decade later, we’re opening a new chapter. TheDAO Security Fund: activating 75,000+ ETH to strengthen Ethereum security. thedao.fund

@gmoneyNFT What prompt did you use?

Claude is amazing. Just did a comprehensive genetic analysis in about 10 mins this morning. Found out was consuming some stuff I shouldn’t have been, ordered some supplements to help me out.

This is your weekly reminder to stay trustless ✌️

@gaudenzio_eth @VitalikButerin @yoavw Love that you’re rocking your trustless manifesto poster all over the world!

While some shake hands at Davos, others bring uncomfortable truths @VitalikButerin. The World Economic Forum convenes to discuss "rebuilding trust" in institutions. Meanwhile, @yoavw, Vitalik, @ThewizardofPOS answered with The Trustless Manifesto: we shouldn't need to trust at all. trustlessness.eth.limo/general/2025/1… The inconvenient reality: Every centralized system begins with good intentions. Gateways become platforms. Platforms become landlords. Landlords decide who enters and what they do. @ethereum wasn't built to make the old system more efficient. It was built to make it obsolete. The manifesto's message is clear: -Self-sovereignty over delegation -Verification over blind trust -Code over policy -Math over middlemen Trustlessness costs complexity, latency, and mental effort. It buys resilience, longevity, neutrality, and freedom. The drift is already here: Hosted RPCs as defaults. Centralized sequencing. Upgrade keys that never disappear. Cross-chain relayers acting as gatekeepers. Decentralization doesn't die through capture, it erodes through convenience. So yes, I'm at Davos. Not to participate in the theater of "rebuilding trust," but to remind the architects of centralized systems why we're building the alternative. Someone has to be here as well @VitalikButerin Some conversations need to happen in uncomfortable rooms. The world doesn't need more efficient middlemen. It needs fewer reasons to trust them.

Decentralized social needs to feel like social to succeed. Currently, it feels like crypto news in a feed. It should feel like a normal app that happens to run on crypto rails. I should be able to onboard my normie friends. They should enjoy the app experience & not get bored.

FOCIL matters bc it hardens ethereum’s core promise: if a tx is valid, it gets in. It ensures institutions, L2s, DeFi users, & everyday txs all get the same inclusion guarantees, even under pressure. Credible neutrality at scale is the future of ethereum! FOCIL for Hegotá 🚀

@andruyeung Was this thread about me?

The most successful people I know all have an almost irrational belief that everything will work out And I just recently learned the word for it: Pronoia. It means the opposite of paranoia. The belief that the world is secretly conspiring in your favor. The funny thing about Pronoia is that it's self-fulfilling. When you believe things will work out, you try harder. You persist longer, and you see opportunities where others see dead ends. What's that quote again? "Pessimists sound smart. Optimists make money." – Nat Friedman We all need a little more pronoia in our lives.

@_franzihei @yoavw @VitalikButerin Thanks for signing the manifesto 💖 keep Ethereum trustless

I know I'm late to the party but in case you didn't read it yet - please do so now! Thanks to @yoavw, @ThewizardofPOS and @VitalikButerin for stating so clearly why trustlessness matters for Ethereum and the world. 🤍 trustlessness.eth.limo/general/2025/1…

I just signed the Trustless Manifesto! 📜 "Trustlessness is expensive. It requires redundancy, openness, and complexity. [...] Trustlessness depends on free open source software — not only code that can be read, but code that can be freely run, verified, and improved." 💯
