Formal verification is all the rage, given the excitement about auto-formalization

The Ying memory profiler was released last week in the middle of Rustconf. It's the easiest path to memory introspection superpowers for Rust. Thanks @Evanfchan!

Recently at @0xMiden we started getting AI-assisted security reports at a rate hand-triaging could not survive. So I wrote up the workflow we now use to triage them, where nothing moves without evidence. www.garillot.net/posts/2026/...

Triaging security reports with a workflow that demands proof
I work on Miden, where we build a zero-knowledge virtual machine. Programs execute in miden-vm, our ZKVM implementation, and the prover produces a proof that each execution was correct. Like a lot of open source projects this year, we started getting security reports written with AI assistance, in numbers that hand-triaging could not keep up with. This post is a piece-by-piece walkthrough of the workflow we now run to triage that queue, in the order a report meets each piece. The full workflow file is public as a gist, and nothing in it is specific to Miden beyond repository names, so you can adapt it if your own inbox starts to look like ours did.

A partial list of historically "edgy" / "risky" behaviours that could expose your cryptographic keys through weak, repeated, predictable, biased, or subverted randomness: 1/13

Google’s latest Shor resource estimate: secp256k1 ECDLP (and ECDSA over that curve) may be breakable with <500K physical qubits under specific assumptions.

There's much talk about Q-day, the future date when quantum computers become powerful enough to break some of today’s public-key cryptography—specifically RSA & elliptic-curve schemes. We do have good quantum-resistant cryptography, but when should we invest the work needed to switch?

One thing to recall from @hdevalence.bsky.social 's work: @lmao.bsky.social, @pinged.bsky.social & @alexhevans.bsky.social showed that just encrypting a continuously updated CFMM (e.g. via FHE) fails to provide real privacy, since the very structure of a live, convex invariant leaks information.

At ACM #Facct2025, learning that LLMs face diminishing returns & comparatively worse task-specific performance when fixating on a larger scale. arxiv.org/abs/2409.14160 (paper by ‪@sashamtl.bsky.social‬ ‪@gaelvaroquaux.bsky.social‬ & ‪@meredithmeredith.bsky.social‬)

I spoke at @protocol_berg on Modern Multi-Proposer Consensus. Consensus researchers know that algorithms like Mysticeti and Cordial Miners now elegantly blend HashGraph's virtual voting and @brynosaurus's Threshold Logical Clocks on a DAG. High throughput, low latency, the dream.

Ever wonder exactly where your Rust code spends its time? I wrote a note on how to light up perf bottlenecks with Tokio’s tracing and the lightweight tracing-texray layer.

I might just have stumbled on the same functionality for Rust, and it was indeed quite simple to do! Have a look at github.com/huitseeker/l... : hopefully this is useful for someone! Thanks @filippo.abyssdomain.expert for the inspiration and @simonwillison.net for the llm tool! #rustlang #llm

New blog post ! Byzantine Consistent Broadcast (BCB) has re-emerged as a path toward ultra-fast digital asset transfers. Projects like pod and delta claim major performance gains through parallel execution—but what's the catch? 1/7

The recording of my talk at the Agglayer Summit in Bangkok is out ! I tried to outline an approach to ZK-proof verification that combines parallel processing, sharded state, and 500ms latency. Here's to making proof verification more accessible & efficient in 2025! #ZKProofs
