No fable here, no lesson. No singing meadowlark.

I'm thrilled to announce that I'll be joining Bluesky as interim CEO. I deeply believe in what this team has built and the open social web they're fighting for. More here: toni.org/2026/03/09/c...

In 2025, as Bluesky grew from 25M to 42M users, we took actions to keep it welcoming, using proactive design to reduce toxic content by 79%.  Our 2025 Transparency Report shares how we're building a safer platform while keeping a transparent and human-centered approach: bsky.social/about/blog/0...

🧵 Could Bitchat have 5x the range and 100x the throughput for the same power expenditure? I explored how Wi-Fi Aware could improve the reliability and throughput of Bitchat and mobile ad-hoc networks in the absence of internet connectivity. #bitchat 👇

Module 5 is live! We’re diving into The Ligero Proof System with @mvenkita and @GuilleAngeris Thanks to @BainCapCrypto for the support. Full access to all module resources zkhack.dev/whiteboard/s...

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.

The Accidental Computer: Polynomial Commitments from Data Availability (Alex Evans, Guillermo Angeris) ia.cr/2025/918

Very informal experimentation with combining two worlds I like ☺️ www.notion.so/Verifiable-... 2/2

Some thoughts about how verifications in Bluesky can be extended to ZK-based methods, to achieve Verifiable Verifications This builds on ideas from the recent verification protocol, and explores both direct integrations and lightweight ones, with different points in the tradeoff space of trust 1/2

🧵 The AT Protocol shows the power of a personal data store. All of our public atproto data is easy to find and access. We can interact with it flexibly in myriad ways and combinations. Wouldn't it be nice to do the same for our private and collaborative data? 👇

The last of @grjte.sh’s Groundmist experiments, combining #localfirst with ATProto Private, local first sync that is user centric using Lexicons, rather than app-specific sync.

ZK provers on mobile? some thoughts on what needs to change to uphold the security guarantees we work so hard to get tl;dr - the deployment supply chain, at least, should be better www.kobi.one/The-Lies-Our...

🧵 The AT Protocol (atproto), which underlies Bluesky, lets us to interface with the same data in as many ways as we can conceive of through AppViews that each provide a different "view" of the network. Can we make our local-first software as interoperable as the AT Protocol? 👇

Second in the #groundmist series - #localfirst + ATProto I’m actively using the local first essay editor (using @inkandswitch.com Automerge + tiny essay editor) - I can login with my ATProto account and work on private drafts and then publish to @whtwnd.com.

🧵 I've been experimenting with combining local-first software and the AT Protocol (atproto) to play with the design space of apps that live at both ends of the privacy spectrum - maximally private AND maximally public, without some of the downsides of the modern web.  Why? 👇

When Andrija and @lmao.bsky.social told me they're writing an extremely fast cryptography library in Julia I didn't know what to think... And then they showed me the following cool stuff: baincapitalcrypto.com/releasing-c... 1/4

friendly reminder that building on atproto gives you immediate access to >30 million users, an existing social graph, and a huge network of open data & content it's increasingly becoming a no-brainer to build new social apps on atproto congrats to the skylight team on the launch 🙌

anon, what if you could train your own personal offline model, on your phone, suited to your tastes, filtering posts with ~ bad vibes ~ and letting good ones through? well, have i got the thing for you

15 weeks ago I sat down and wrote up some ideas about how custom feeds could become a high-leverage mechanism for fundamentally changing the economics of the attention economy. Today was my last day at my day job- I’m now full time @graze.social! Incredibly excited to give this all I got!

This week's ZK Podcast episode was on ZODA & The Accidental Computer from @baincapitalcrypto.com research team, with the trio @alexhevans.bsky.social @guilleangeris.bsky.social @nicomnbl.bsky.social chatting with @arro.bsky.social about these innovations. Ep: https://zeroknowledge.fm/podcast/349/

it's funny, for a long time, i always assumed that computation was this very sacred, brittle, difficult thing: so many things need to work "exactly" right to get an output but i’ve realized that it’s actually much *harder* to make a thing that doesn't accidentally enable ~ arbitrary computation!

These two lectures by @danboneh.bsky.social for @zkhack.bsky.social are the best explanation of IOPPs, FRI and its variants by a country mile. Cannot recommend them enough zkhack.dev/whiteboard/s... zkhack.dev/whiteboard/s...

oh hello @zkhack.bsky.social 👀👀

Welcome Mark Fiorentino to BCV! As Matt Harris writes, Mark is constantly learning w/ a career+life trajectory powered by changes, pivots & the quest for new experiences (ask him about being a Sommelier or upcoming CrossFit competitions). baincapitalventures.com/insight/mark... #fintech #SaaS #AI

ZODA w/ @alexhevans.bsky.social and @nicomnbl.bsky.social : now up on eprint! (with a few updates and smol changes to the appendix)

Cool checking out @graze.social -- ability to generate, share, (one day monetize?) your own type of feed. I wonder when we'll have dynamic, prompted LLM-style feeds. Aka say "make me smarter, show me things that are funnier" and the feed will be curated as such

this is a great writeup on the differences between atproto & activity pub it also highlights the most meaningful ways to make bluesky more resilient

Maybe the most interesting DeFi research in recent years

Everyone on the X is too distracted with immigration, so I’m giving a sneak peek of some research here Decentralized Perpetuals have long been the dream but they’ve been too capital inefficient Many advances pushed DEX-CEX market share to >6% — but how are how are they related? We answer this!

if someone tells you “succinct proofs are too short to leak information about the witness”, please send them this. The ZK property is not just a cool acronym. baincapitalcrypto.com/chosen-insta... This was also the theme of the "Zeitgeist" puzzle at ZK Hack 5!

ZODA Joint work with @nicomnbl.bsky.social and @lmao.bsky.social (with help from our friends Nash, Sanaz, and John at @celestiaorg.bsky.social) A minor tweak to the encoding procedure makes data squares like Celestia's provably correct Paper: bit.ly/zoda2 Blog: bit.ly/zoda1
