πCreds is out!! Come see how to prove things about yourself to third parties — your health status, financial reliability, or that you're actually good at your job — without giving up your data 👇

1/ Privacy-preserving credentials can prove you're over 18, but not much else. New IC3 research changes that. 𝜋Creds introduces verifiable credentials generated by trusted LLM inference over authenticated data.

Feed-forward 3D reconstruction methods typically predict pointmaps in camera-centric frames. But why should a camera's arbitrary orientation define the coordinate system?
We introduce G3T, a transformer that predicts pointmaps in gravity-aligned frames. Regardless of input image orientation, our method always produces upright pointmaps (see demo).
We leverage this uprightness to create G3T-Long, a submap-based reconstruction method that improves robustness on long-sequence 3D reconstruction (more on that below).
Interactive demos, code, and model weights are available on our project page.

@BlockEnthusiast @AriJuels Great point—our system handles this with a corrected noisy tally, which publishes the noisy totals alongside the true winner. This raises a key question under DP: how does revealing the winner affect the effectiveness of the noise? We provide bounds that answer this on Section 7.

@AriJuels How do you avoid swinging close votes when adding noise?

Secret-ballot crypto voting—e.g., in DAOs—is a great idea. But our research has uncovered a privacy gotcha.

@sightnoah @AriJuels Great question! Quadratic voting increases B-Privacy when combined with noised tallying. It reduces whale dominance, which in turn raises the minimum decisive coalition size (the number of voters needed to flip an outcome) making bribery significantly more costly (see Figure 6).

@AriJuels Great work!
The general trend seems to be toward weighted quadratic voting with zk-uniqueness verification. Would the quadratic transformation affect the bribe-ability/discoverability?

Paper: B-Privacy: Defining and Enforcing Privacy in Weighted Voting available at arxiv.org/pdf/2509.17871. Co-first-authored by Sam Breckenridge and @danivilardell77, with Andrés Fábrega, @theamyzhao, @stonecoldpat0 (Arbitrum Foundation), @rafaelsolari (Tally), and yours truly.

Check out the new research on privacy in DAO voting by @stonecoldpat0, @tallyxyz, @theamyzhao and folks at @initc3org!
They show how weighted voting can leak voter choices, introduce a new framework called B-Privacy, and propose ways to make bribery much harder.

New IC3 research: Token-weighted voting in DAOs is common across web3, but comes with a serious privacy flaw: voter choices can be inferred from tallies even if ballots are kept secret. 🧵⬇️

Take My Ape is out! Try it at takemyape.com.
Own a Bored Ape for 15 minutes with one Ethereum transaction.
Ownership ≠ rental. It means copyright license, access to BAYC spaces, and your address on chain as owner.
TMA's goal? To demo the power of Liquefaction.

We've now publicly released code for Liquefaction: github.com/key-encumbranc….
Liqufaction privately liqufies any blockchain asset, showing how TEEs are poised to transform the blockchain landscape. Impacts in the table below.

Locked / unvested tokens. Airdrops. Soulbound Tokens. DAO voting. These crypto applications all have one thing in common…
They assume critically that private keys are controlled by an individual.

NEW: IC3 researchers present Liquefaction — a wallet platform that redefines private key control in crypto.
Liquefaction allows private key access to be shared, rented, or pooled, supporting multi-user policies around crypto assets without direct on-chain traces. Trusted Execution Environments (TEEs) help make this possible.
