ok hear me out, what if you could encrypt to a TEE that doesn't exist (yet)? Turns out, if you flip the QAP we use for groth16 proving systems you can construct a witness encryption scheme for TDX attestaions. IMO big for confidential and censorship-resistant P2P systems? (besides v interesting applied cryptography).

fortunately and unfortunately LLMs are still kinda bad at writing complex (correct) formal specs from natural language.

I wish I could just have a clone of myself that writes about all the experiments I'm working on. It's a never ending loop because just when I'm typing the writeups I get more ideas that I must immediately work on.

do you think concrete can be relevant as its own language? idea is excelent and the work you guys have been doing as well (it's also helped me draw several conclusions on our pipeline for tightening gaps btw execution <> definition). To me tho the underlying idea can be evantually separated from the language and retrofit with existing tooling once we have a production lean frontend + e.g a verified rust backend. Or is there an angle I'm not seeing here? (I still haven't read the full series tho, had only read episode 4, hopefully will have time to go over the others in the weekend)

Great week: - multiple of our companies growing at two digits per week - @alignedlayer risc-v zkvm performance becoming top notch - @alignedlayer and @class_lambda find another riscv zkvm soundness bug - i finally finished the PoC and paper of what I consider a relevant finding in AI. the math lambda team already double checked things - concrete, our programming language is becoming better and better. i will soon explain why is it so good and important in an AI world

@minimario1729 have you tried with types that are not from mathlib i.e. non striclty mathematical theorem statements?

🚨 Math Inc is introducing FormalQualBench: an open-source benchmark for end-to-end auto-formalization capabilities with math PhD qualifying exam level problems. We build this benchmark for the Lean community, allowing anyone to compare different auto-formalization agents!

Math, Inc.@mathematics_inc·
Today, at the @DARPA expMath kickoff, we launched 𝗢𝗽𝗲𝗻𝗚𝗮𝘂𝘀𝘀, an open source and state of the art autoformalization agent harness for developers and practitioners to accelerate progress at the frontier. It is stronger, faster, and more cost-efficient than off-the-shelf alternatives. On FormalQualBench, running with a 4-hour timeout, it beats @HarmonicMath's Aristotle agent with no time limit. Users of OpenGauss can interact with it as much or as little as they want, can easily manage many subagents working in parallel, and can extend / modify / introspect OpenGauss because it is permissively open-source. OpenGauss was developed in close collaboration with maintainers of leading open-source AI tooling for Lean. Read the report and try it out:

the fact that @leanprover gets you to native code from a proof is too undervalued; no intermediary = what is proven is what is run. i.e. we can get kernel checks on proven rules. extracting algebraic properties from generic transformations to express them as eval is going to be interesting for optimizations.

all this makes more sense once I fully finish this one piece: heytdep.github.io/research/verif…. not the core of the idea but a pyramidal LLM model here feels very interesting for adversarial mechanisms; high level idea is open model gets hold of formal spec over confidential code > finds security gaps in spec i.e properties that must be satisfied > frontier model validates if suggested properties are redundant/invalid // open model autoresearches to improve and trains on feedback from frontier model, confidential code and provided specs.

if your "agentic harness" relies on external apis and models, keep in mind these are being cost subsidized a la uber and will be jacked up soon sovereignity is only building what you can

@mempirate agreed. unless you have some degree of trusted execution leaving easily configurable anything that is not protocol is the best way to document possible states. common example is network-level censorship, arguments against are virtual signaling imo (if outside of protocol ofc)

An interesting discussion point on configurable timing games for the new direct proposer-to-builder API. I agree that sophisticated proposers will find a way around this any way, widening the gap between them and regular validators. (Or it just invites continued usage of relays)

good take on many counts; most interestingly preparing for the end of the inference subsidy and privacy/trust

@heytdep models are a pyramid we have passed the frontier only era imo only funnel things up when you have to. the frontier models code a harness for the open models, but never actually get the sensitive data using this approach I have reduced my frontier queries 98% or more

@phildaian was just now trying to solve an issue in a formal verification workflow I'm working on and this exact reply might've partially solved it (i.e largely improved) for me.

Cool read. if you want to see how to elegantly handle post handshake attestation read this <- hooks are a very natural way of doing this IMO as it makes it almost feel like it's part of the handshake when it isn't.

@mempirate indeed. "boringly" tcp having effectively bounded and occasionally spiking delays makes it work best with partial synchrony.

@heytdep Without partial sync we wouldn't have Tendermint though 🥲

Async is more fun than partial sync while sync is really fun. (Opinion subject to change)
