Detecting Crashes with Fat-Tail Statistics
We built fatcrash, a Rust+Python toolkit with 17 crash detection methods: LPPLS, DFA, EVT, Hill, Kappa, Hurst, GSADF, momentum/reversal, price velocity, and 2 n…
I grew up in Argentina, where you learn early that money breaks, institutions fail, and the systems people depend on are more fragile than anyone admits. That shaped everything I build now.
Through LambdaClass I build one of the fastest Ethereum clients, a new programming language called Concrete with a formally verified kernel, and the cryptographic infrastructure that protocols depend on. Through Ergodic Group I hold companies across distributed systems, AI, gaming, wine, and culture. This site is where I write about what compounds over time rather than what trends today.
We tested Spitznagel's tail hedging strategy and AQR's critique with 17 years of real SPY options data. AQR is correct about a strategy nobody runs. Spitznagel's actual strategy, leveraged deep OTM puts, wins on every metric. Weekly rebalancing pushes Sharpe to 2.0. Macro signals are useless for timing.

We assembled forex-centuries, an open dataset of exchange rates, gold, silver, interest rates, commodity prices, GDP, sovereign debt, and more — 27 sources span…
The scarcity that matters most in a post AGI world won't be compute or energy. It will be desire itself.
What if consciousness emerged in humans when external dialogue internalized? Could multi-agent AI be building the same precondition?
If AI makes cognition cheap, portable, and good enough, services lose margin and geopolitical advantage shifts toward players that pair industrial scale with co…
Our stack and practices for building SaaS applications: Elixir on the backend, React on the frontend, Nix for everything else. No Docker. No Kubernetes.
Humanity is completely unprepared for what's coming. The pace of AI advancement might give people months to adapt, not decades.
A practical guide through the landscape of type systems, from everyday generics to dependent types that prove correctness, with examples in Rust, Scala, and Idr…
Concrete is a systems language proposal built for machine reasoning, aiming to combine low-level performance with formal verification, safety, and expressive de…
A draft thesis that individuality and modern consciousness are historical coordination technologies now being eroded by computation, capital, and automated feed…
A framework for building institutions that compound under pressure: treat time as information, preserve loop integrity, and focus on domains where repetition im…
Ethereum is emerging as a neutral financial backend, lowering the cost of global financial services by encoding ownership and obligations in shared infrastructu…
The internet scaled information but not ownership institutions; Ethereum addresses this gap by embedding rights, records, and enforcement into programmable econ…
Discussion about Ethereum's native rollup roadmap
Crypto found product-market fit where trust is weakest: inflationary or censored economies, and internet-native communities that need programmable coordination …
Zero-knowledge proofs, FHE, and modern distributed-systems primitives can expand trust-minimized coordination by proving computation correctness without reveali…
