Replying to @DCinvestor
We use a ton of AI in testing, working with LLMs to define test plans and letting them execute stuff in contained local kurtosis runs. Devnet tools all got an API so we can programmatically test stuff.
github.com/ethpandaops/panda became the central way to ingest logs,
There is exactly zero chance this goes live in 4 months
This is so disappointing on every level.
EIP released with 48 hours notice for comments. Realistically 4 months before it goes live. For a major network economics change with far reaching implications for all of DeFi.
Every builder on Ethereum opposes this. Why is this a focus?
None of the reasoning makes any damn sense.
This will self evidently push out solo stakers who aren't subsidized by the EF or others. It will essentially guarantee that the only ones staking are large centralized entities with zero cost of capital where users passively hold their ETH. Why?
It will obviously kill a huge chunk of DeFi which is built around the staking ecosystem. Seven of the top 10 DeFi protocols with face a capital exodus. Why?
Is the idea that a 0.8% reduction in issuance is somehow going to help ETH price? People who stake ETH don't sell it. This change will halt any new ETH getting staked and realistically will result in tens of billions of $ of ETH getting unstaked and entering into the market, not to mention the implosion of the core Ethereum use case. Why?
Is the concern that liquid staking tokens, which intermediate about a quarter of staked ETH, displace ETH as money? This reasoning betrays a cash-accounting level of understanding of the economy, as if only M1 counts as real money. LSTs serve as valuable building blocks, and in fact implement a lot of user protections that would not be appropriate to do at the network level. At a near zero cost of 10-15 bps.
I say this as a builder on Ethereum, not as someone who stands to benefit from staking issuance. I don't have much at risk here. Almost all of @ether_fi revenue is now coming from vaults and payments, staking is a small (and shrinking) part of our business.
This is bad for decentralization, this is bad for Ethereum adoption, and this is bad for the credibility of the network to roll things out this way.
This reinforces the Ethereum critics' position that the network is run by a small group of insiders with no regard for the actual users and builders on the chain. I can say that neither I nor any builder I know was asked for feedback on this before it went live.
Any nation state or large institution looking at this will justifiably have a dramatic loss of confidence in the governance and stability of Ethereum.
> Fable 5 will be included for up to 50% of weekly usage limits through July 7, after which it will be available via usage credits
Claude Fable 5 will be available again globally tomorrow.
After a series of productive conversations with the US government, we're redeploying the model with a new set of classifiers to target and block more cybersecurity tasks. In the near term, some routine tasks like coding and debugging will fall back to Opus 4.8. We’ll continue to refine these classifiers over the coming weeks to reduce false positives and better distinguish genuine misuse from legitimate requests.
We’ve also begun drafting a consensus framework—with Amazon, Microsoft, Google, and other Glasswing partners—for assessing the severity of AI jailbreaks and how AI developers should respond to them. We invite other industry partners and model providers to join us in this effort.
Finally, we’re scaling up our collaboration with the US government on model testing and safeguards. This will include pre-release access to models and safeguards for evaluation, information sharing on jailbreaks and misuse, and dedicated resources for joint research.
Thank you to our users for your patience, and to our partners across the government, industry, and the research community who worked alongside us to make Fable 5 available again.

STRONGLY recommend reading this one if you're thinking about how your team or organization interacts with your platform.
While it's still not perfect, we've landed on something that ticks a lot of boxes and has been a real productivity multiplier for our team.

A year of backtesting for the Fast Confirmation Rule confirms (!) that:
- 96% of past blocks would have been fast-confirmed in a single slot. This could mean deposits from Ethereum to L2s or CEXes available in about 12 seconds!
- The remaining 4% are usually confirmed fast too, usually much faster than other, less secure confirmation rules such as k-deep confirmations
- No false confirmation is ever issued
Client implementations continue 🫡
Some really positive results here. Looking forward to the fast confirmation rule rolling out and adoption picking up!

The Flash variant is a large step increase on the cost Pareto frontier when looking at just EVM execution. The architecture improvements across long context are probably directly responsible here.
You can expect this model to stay coherent on longer chats compared to others at its price point.

Two can play this game.
Solana feels like it was designed by devs that haven't actually worked on distributed systems: "let's scale by throwing hardware at the problem and coordinate validator restarts over Discord when the network halts"
Ethereum has been built by devs focused on correctness: "years of real load and active attacks haven't taken down the chain. Let's scale without compromising that."
Please have a day off from the crypto PVP.
Ethereum feels like it was designed by architects and researchers that haven’t actually worked on scalable systems: “let’s scale by creating microservices that all require pushing updates to a stale system that doesn’t work under high load”
Solana has been built by pragmatic devs focused on high throughput systems: “live load tests revealed bottlenecks in the transaction ingestion, block propagation, and block space. Let’s fix that and continuously optimize”
Grok 4.20 scored 56.3% on EthIQ, placing it around Claude Sonnet 4 & GLM 5 level.

Grok 4.20 deep dive: ethiq.ethpandaops.io/model/g…
xAI has released Grok 4.20 for API access in beta, and it scores 48 on the Artificial Analysis Intelligence Index with reasoning enabled
Compared to @xAI’s previous Grok 4 flagship, Grok 4.20 Beta 0309 is an intelligence upgrade, achieving +6 points on the Intelligence Index. It launches with a longer 2M token context window (up from Grok 4’s 256K context window, matching Grok 4.1 Fast’s 2M), and significantly lower pricing ($2/$6 vs Grok 4’s $3/$15).
Grok 4.20’s performance lags behind the current intelligence frontier, but it performs strongly on instruction following and features a notably low hallucination rate, beating all other models we’ve tested on AA-Omniscience for hallucination.
xAI released 3 variants: reasoning, non-reasoning, and multi-agent. We’ve evaluated the reasoning and non-reasoning modes, and are considering the best approach for testing the new multi-agent functionality, which parallelizes over multiple agents behind the scenes in one API call.
Key takeaways:
➤ Improved intelligence over Grok 4: Grok 4.20 Beta 0309 (Reasoning) scores 48 on the Artificial Analysis Intelligence Index, +6 from Grok 4 and +9 compared to Grok 4.1 Fast. This score falls short of the current intelligence frontier at 57 (Gemini 3.1 Pro Preview and GPT-5.4)
➤ Low price for the level of intelligence: Grok 4.20 is priced at $2/$6 per 1M input/output tokens, representing a decrease compared with Grok 4’s $3/$15 API rates. The reasoning variant cost $484 to complete the evaluations in the Artificial Analysis Intelligence Index, which is a reduction of ~70% compared to Grok 4, driven by lower pricing and lower token use
➤ Leading non-hallucination rate: Grok 4.20 scores 78% in the AA-Omniscience non-hallucination metric. This is the best result we have seen yet for this metric, and reflects the model only answering around one fifth of the time when it did not know the answer
➤ Fast inference performance: xAI is serving Grok 4.20 at 267 tokens per second - similar to what we see for gpt-oss-120b across providers and on the Pareto frontier for speed versus intelligence
➤ Mixed improvements in tool use: Grok 4.20 improved on the tool calling performance of Grok 4 in some evaluations, scoring 97% on Tau2-Telecom. However, its score of 1,062 on GDPval-AA, our benchmark of general agent performance on real work tasks, is well behind frontier peers and sits approximately in line with Grok 4.1 Fast
In retrospect asking `llama-3.2-instruct-1b` to step through the EVM & do consensus shuffling was quite cruel. It had a solid crack though!

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.
