Been heads down building the Cabal app and it's coming out soon! Website is out at cabal.cooking If you want to learn more about the app, NFT collection, and token, give this a read🫡
Today, we're releasing the first look of the Cabal app, the Hushpuppies NFT collection, and the $CABAL token. Cabal is the private social trading app on Robinhood Chain. Read the thread🧵👇

✨Introducing ZKLean, formal verification for interconnected software✨ Frontier AIs keep finding critical bugs everywhere. Formal verification is the obvious cure, but what if your software has dependencies like npm packages or API endpoints? ZKLean is the solution👇

This means you can: - Cheaply check formal specs released by your dependencies - Ensure your formal proofs don't break on every release - Cheaply prove to someone your software is formally verified Repo: github.com/ZeframLou/zklean

I also made a library called HTTPV (HTTP-Verified) HTTPV lets your server serve ZKLean certificates for each API endpoint, and lets your clients verify those certificates cheaply. Drop-in replacement for Bun.serve() Repo: github.com/ZeframLou/httpv

People are confused about semis dumping and gpu spot price increasing. This is only because demand is moving to open source models, and all the GPUs are being hoarded by the big labs or stuck under commitments, so GPU on the rental market absorb the demand. IMO SpaceX will drop the race, and will fully pivot to compute provider. Thesis is the same, frontier is platauing, reward on training is getting lower, and all of a sudden big labs hoarding gpus will rush to capture the inference margin before it collapses.
There is an absolute barrage of inference providers popping up that get to $1M/mo extremely quickly. This is the rough economics of inference providers: Even if you rent on-demand B300s at $8/GPU-hr, many open source models (GLM 5.3, Kimi K3, DeepSeek 4.1 Flash / Pro) can get you >$10-20/GPU-hr at reasonable throughputs (100tok/s). DeepInfer from DeepSeek directly shows they can get $38/GPU-hr on off-peak hours. Every chip / model has a different throughput / interactivity curve, but there is a lot of arbitrage between even high rental spot prices and token prices. New chips (Vera Rubins) also change this meaningfully. Your ability to be making gross margin relies on your utilization and how good your stack is. Gateways like OpenRouter, Vercel and more help solve that problem by aggregating demand to you. May inference providers discount their tokens to get longer term commits too. I've even heard stories of selling back Chinese model tokens to Chinese labs! One thorn in the economics of these players is that many Chinese open source model labs are now asking for rev share if you're at a certain scale, espp for pre-release access to their models for day 1 support. That further pushes the threshold to be in the money. The barrier to entry seems low and falling. There are even stories of smaller ones who can "vibe code" a way to stand up OSS models on a cluster they rent. And as a result, we're seeing 10s of such companies pop up almost every week and immediately skyrocketing revenue at low-ish gross margin and raising rounds on the back of that. Unsurprisingly, because the actual service provided seems commodity, this eventually drives up compute prices and drives down token prices. In theory, it would seem like neoclouds who have the lowest cost of compute and themselves have started inference businesses would win the race to the bottom (Crusoe Coreweave Nebius and GMI all have inference businesses), with larger players (Modal Fireworks Baseten) being second because they are well capitalized to make bigger compute commits cheaply and have demand (high utilization), but the reality is the pie is growing so quickly that even upstarts are absolutely crushing it and growing aggressively (inference dot net, DeepInfra, Wafer, Relace, Morph). Strategies vary across the board: neoclouds want to serve inference, inference players want to be neoclouds and do higher margin reserved instances / post training, and some want to go heterogeneous hardware or creatively flexible compute constructs. The risks are: do open source models continue to be competitive? Will their creators rent seek more? Will their shape change compute needs? How do different chips change economics? Who gets compute in a supply crunch? Below is a aggressive sketch of how gross margin scales with utilization for various models / chip sets. For now, there are many inference providers and they’re all ripping!

Introducing Tama, a dev toolchain for secure-by-construction EVM smart contracts Tama enables you to build provably secure apps in 3 steps: 1. Code: write the contract itself 2. Spec: define what correct behavior looks like 3. Prove: prove the code matches the specs

Introducing Tamago🍳, a standard contract suite for Verity analogous to Solady for Solidity First ever (!!!) formally verified implementations of sqrt(), cbrt(), log10(), and log256() in EVM. Also the first ever formally verified ERC-4626 vault! cc @VitalikButerin @Fricoben

If you’re formally verifying software with Lean and you’re not proving inductive specs you’re doing it wrong Inductive specs allow you to describe and prove powerful properties like “this app will never crash” or “nobody can steal funds”

What do you mean I can just buy GitHub stars? I’ve been a sucker for getting stars by building cool and innovative things I suppose
so i have been in the sf tech scene for a couple of months now, and i learned the games that ppl play 1. land a $3M lab order in 2 weeks, *26 = ~$80m as the annual revenue 2. schedule all orders to be signed in the same month, and multiply the best month by 12 3. sign $5M LOIs with friend's companies and batchmates. they sign one back (also happens at scale with large labs/compute) 4. buy github stars at 6 cents each the last company that swapped invoices with a partner reported $220M - and it's bankrupt now sad that it's a whole gresham's law game right now and if you dont play you just get downvoted

Pretty wild
Did you know that in the nix bootstrapping chain, there's as much code implementing C++ as there is doing *everything else combined* (Linux, Python, Perl, make, autotools, a Scheme interpreter, ...) Compilers are big, monolithic, and pull in a lot of complexity.

What if: - Startup equity as collateral - Borrow GPU access Maybe onchain. Who’s building this?

Formal verification at the compiled bytecode level is insane work If Anthropic can do that, why not simply formally model popular languages/compilers which can then be used to much more easily prove code written in those languages?
New on our Frontier Red Team blog: using Claude to formally verify software at large scale. Formal verification can prove that code is free of certain bugs, but historically it has only been feasible for small codebases (or required a lot of expert time). With AI models, however, this is beginning to change. In collaboration with @theoremlabs, we used Claude to prove security properties in over one hundred real-world open-source libraries over the span of a few weeks.

PSA: Do NOT use public WiFi or shady DNS servers for the next few weeks. SSL is practically broken and you can be attcked with an MITM attack. Your ISP and other intermediaries can also spy on you. Use a trusted VPN. It will take a few days at least to flush out this crap CA.
Instead of using 384 bit random private keys, they used private keys like the super secret, unguessable number 4. They are a cryptography company. They had one job. They're selling Post-Quantum Cryptography while doing shit like this lmao.
Readers added context they thought people might want to know
SSL/TLS is not broken. The vulnerability involved eight eMudhra intermediate certificates, which major browsers and operating systems (Chrome, Firefox, Apple, and Microsoft) had already blocked by October 20. Updated devices are protected against these MITM attacks. arstechnica.com/security/2026/… emudhra.we-have-a-problem.com

Introducing the US Gov Graph - a complete map of the people and positions of power in the federal government. To fix our institutions we must understand how they work, so we are using AI to model and monitor every government in America. This is Palantir for The People. Check it out here: graph.civlab.org/us We exist to set the conditions for an era of civic excellence unmatched since the Founding. We will need nothing less to navigate the age of AI. I'm looking for exceptional engineers and designers to work with me in San Francisco. If that's you, inquire here: tally.so/r/KY97RK. Self-governing civilization is counting on you.

Due to popular demand, we have renamed the Hushpuppies NFT collection to ZK9s. Cabal uses ZK technology to provide true onchain privacy to traders, and the new name emphasizes that (and is *just cooler*) Woof woof🐶
