We’re bringing Aristotle to code. AI is writing more code than anyone can review. We're building the AI that verifies it. Starting today with C and Verilog.

This Saturday, our formal verification engineer Petar Maksimovic (@petarmax) takes the stage at Scale or Die in London. See you there, @solana_devs!

Yesterday we said all code will be formally verified in two years. A lot of you asked how, so here’s how we think about it. 🧵

One sentence. That’s the whole prompt. Aristotle proved every multiply and divide instruction in the Ibex RISC-V core matches the official RISC-V spec, divide-by-zero and signed overflow included. @satnam6502 walks through how he did it 👇

This article shows how a one line prompt can be used to formally verify MUL and DIV instructions of the Ibex RISC-V CPU using Aristotle. It's incredible easy to get started with formal hardware verification when you use Aristotle.

Your first $500 of Aristotle is on us. Pick the C function or Verilog module you trust least, and find out whether you were right to worry. aristotle.harmonic.fun

assert(len <= buf_size) means “this never happens.” Your tests check that on a few inputs. Aristotle proves it for all of them. Try Aristotle today: aristotle.harmonic.fun

A buffer overflow sat in PXE boot code for 16 years. We built Aristotle for bugs like this. You write the rule in English, like “the copy never runs past the buffer.” Aristotle proves your code, or finds the input that doesn’t. How it works: harmonic.fun/aristotle/?r=x

‼️ Critical 16-year-old flaw in EDK II UEFI firmware could let attackers execute code before Secure Boot checks. CVE-2026-97631 affects PXE network boot, requires local network access and target-specific exploitation. No patched stable EDK II release yet. Full details → thehackernews.com/2026/10/cr…

Fifty years of C and we're still shipping buffer overflows. Aristotle proves your C does what you said it should. When it doesn't, you get the input that breaks it. New sign-ups get $500 in credits. Get started with the most effective way to protect your enterprise: aristotle.harmonic.fun/?r=x

Tensordyne gave Aristotle its hardest block to verify: 12.2 million gate equivalents. 185 properties proved, 56 refuted. Jonathan Ko, their verification engineer, calls it "unthinkable with traditional tools." Read the the full @TensordyneInc case study: harmonic.fun/aristotle/case-…

Aristotle proved 185 properties of Tensordyne’s most complex block, refuted 56 with counterexamples, and found bugs up to 110,000 cycles deep.

You don't need to be a formal verification expert to use it. What used to take years to master can now be run by any engineer on every commit.
