excited about zk, solving hard problems, or building with a world-class team?

we’re hiring at @succinctlabs 👇

@SuccinctLabs Right place. Right time. Right team.

[Succinct @SuccinctLabs]

Migrating Ethereum to post-quantum security is a herculean task. That's why we released VEIL, a new compiler.

Succinct's SP1 — the protocol Google used for generating ZK proofs — relies on a Groth16 wrapper. VEIL swaps the elliptic-curve dependency for a PQS hash-based one.

@yugacohler @CoinbaseDev Congrats Yuga!

[Succinct @SuccinctLabs]

With the Azul upgrade, the Base network is now secured by validity proofs through Succinct’s SP1.

Base joins Optimism, Katana, and Mantle in adopting ZK proofs, bringing SP1’s total value secured to $13.5 billion.

[Justin T Chen @justintchen]

@Sir_Damilare Big facts

[Succinct @SuccinctLabs]

Succinct is bringing zero-knowledge proofs to @base. The upcoming Azul upgrade will use SP1 to prove every transaction on the network.

Succinct will soon secure over $10 billion across major rollups, making SP1 the most widely deployed zkVM in production.

AI content is indistinguishable from reality.

That's why OpenAI is watermarking its images and adopting C2PA so platforms can flag AI-generated content. But there’s one line that stands out to us, "No single provenance technique is enough."

Here's what we're doing about it ↓

The current approach is to detect what's fake. Our research shows how fragile that is: detection rates among leading AI detectors drop by as much as 90% with simple image manipulation like blur, noise, and compression.

The other half of the equation is to Prove What's Real. That's why we built ZCAM to cryptographically sign photos at the moment of capture using the secure hardware already in modern iPhones. If a single pixel changes — through edits or AI manipulation — the signature breaks. If it holds, the viewer knows the photo is real.

Both ZCAM and OpenAI support the C2PA standard, so information about a piece of media can travel with the content itself. Together, images and videos can be verified as authentic or generated.

SynthID to detect what's fake, ZCAM to prove what’s real.

@jconnorholliman @svmvn Come up to the Bay and we’ll play!

[Succinct @SuccinctLabs]

Cryptographers at Succinct experimented with AI to formally verify VEIL, our newly introduced ZK compiler.

Our findings echo Vitalik's – formal verification, paired with software verification, builds confidence in cryptographic systems.

AI can do this work much faster.

Step 1: make cryptographic money work (Bitcoin)
Step 2: make it programmable (Ethereum)
Step 3: make it scale (Solana)
Step 4: make it private (Zcash)

let's get clarity passed

@jconnorholliman @coinbase Class

[Connor Holliman @jconnorholliman]

One of the worst parts about being impacted by the @coinbase layoffs is no longer being in the Slack channels with my team

I truly miss having everyone in one place

Fortunately, we built such strong relationships that we set up WhatsApp groups, where we’re actively helping each other find our next opportunities

I’m directly connected with some of the strongest ex-Coinbase Talent and Growth people globally

I’m also connecting with ex-Coinbase talent I didn’t know personally on a daily basis, who span Software Engineering, Blockchain Security Engineering, Customer Success, Sales, BD, and many other verticals

I want to help my former colleagues find their next opportunity

If you’re a hiring manager looking for exceptional ex-Coinbase talent, reach out

I’d love to connect you to your next great hire

[Justin T Chen @justintchen]

@em_calderon It's doable!

[Gary Vaynerchuk @garyvee]

So much talking .. too much talking .. everyone’s talking .. not enough playing .. share this with someone in your life who needs to finally “act”

High signal question

[Codie Sanchez @Codie_Sanchez]

My new favorite interview question, "What is the hardest thing you have ever done, tell me about it."

Sadly shocking how many have NEVER done something painfully hard.

[Marc Andreessen 🇺🇸 @pmarca]

The confounding factor is that virtually every big company is overstaffed by 2-4x and has been for decades. AI is the catalyst/excuse to finally fix that. Of course nobody wants to say this out loud.

[edgar @edgarpavlovsky]

if you've been impacted by layoffs at

- @coinbase
- @Cloudflare

and you are an exceptional & agent-native:

- sales / AE
- engineer

my DMs are open, we and a lot of incredible YC companies are hiring & laying their team foundation right now

[Charlie Kerr @charliekerr]

If you were affected by the Coinbase layoff I will gladly connect you with good people.
