Whyyyy join? Because sometimes the best ideas spark over coffee ☕ and a burger 🍔

ZK Cafe is your moment to meet the zk crew IRL, share stories, ask questions, and BUILD together

🗓️ 30 Aug, 11AM
📍 Bangalore

we're waiting for you ~ RSVP and pull up!

Bangalore whattt ??🌍

The next zk stop is here and Proof of Witness is pulling up this Saturday with ZK Cafe

Coffee ☕ burgers 🍔 and zk frens all vibing together to connect and create

but like… what even is ZK Cafe?👀

[ProofOfWitness @ProofOfWitness]

It’s not a talk. It’s not a workshop.
Then wtf?

ZK Cafe is a hangout where builders, devs, and explorers meet IRL

A space to swap ideas, ask questions, share projects, vibe over coffee and burgers 🍔☕

Sounds fun right? But whyy should you join? 🤔

Last week in the Proof of Witness event at Coimbatore, had a chance to talk about Zk beyond buzz words and honestly, the more we talk about it, the more fascinating each time it is.

Super bullish on zk. More coming

[Ajay @le_ajay]

Reimagining Identity through Zero Knowledge Proof 🔥
Tats core of recent zk meetup in Coimbatore. ZK as alternative Blockchain way of modernizing privacy and security layered KYC! To more ZK adoption ⚡

Coimbatore fam showed up heavy

From devs to curious first-timers,
y’all pulled up, asked great questions, stayed curious and brought good energy

snacks were had
POAP were minted
connections were made

with Plenty of “wait this is actually cool” moments🤍

[ProofOfWitness @ProofOfWitness]

ZK Witness Coimbatore was a whole vibe yesterday 🌀

Talks were super chill and useful
The workshop was packed
Some folks built their first ZK circuit ever

big shoutout to @ashwin_dev0x for hosting the entire event

here’s a quick thread on what went down

[ProofOfWitness @ProofOfWitness]

Talk 3: Reimagining KYC with ZK

Mohamed Younus pulled up with one of the most practical zk talks we’ve had

Shared insights from CoinDCX hacks and explained how ZK can totally rewire the KYC mess

def gave fintech + compliance heads something to think about

[ProofOfWitness @ProofOfWitness]

Not just talks we’re running a hands-on ZK workshop made for newbies.

Never built a ZK circuit? No stress, you’ll make one in 30 minutes.

We’ll build a simple age check circuit using Noir. It’s super chill, zero scary math, just bring your curiosity.

Led by @Kaushikk1704

Next stop: ZK Witness in Coimbatore 🎉

We’re hosting a fun, hands-on ZK meetup this Sunday!
Talks, building, snacks, and great company.

Coimbatore folks, we’d love to see you there!💖

Here’s what’s planned

[ProofOfWitness @ProofOfWitness]

If you’re curious about zero-knowledge proofs or want to start building, you’ll want to catch these

@idkshabnam ~ ZK beyond Crypto Buzzwords
@MadhuVarshaP ~ How a ZK Circuit becomes a Proof
Mohamed Younus ~ Reimagining KYC with ZK

Total newbie? We’re here to make it easy

[Kaushik @0xkaushik_k]

Just read a paper on how to make zero-knowledge proofs secure even against quantum computers doing wild stuff like superposition attacks.

Let’s talk about how researchers are tackling this scary but fascinating problem in post-quantum cryptography

So here’s the problem:

In zero-knowledge proofs (ZKPs), one party proves something is true without revealing why.

But with quantum computers, a verifier can do spooky stuff like run the proof in a superposition of states.
That could leak secrets.

This is what’s called a superposition attack where the verifier queries the proof in all possible ways at once (thanks to quantum superposition).

Traditional ZKPs break under that.

[ProofOfWitness @ProofOfWitness]

ZK Witness heads to Coimbatore!

After a packed house in Chennai & Pondicherry, we’re bringing the Zero-Knowledge vibes to Coimbatore!

- Date: 03.08.25
- Location: Coimbatore

~ Talks.
~ Workshop.
~ Real conversations.

Last Saturday,

I had the best time in Pondicherry discussing ‘Zk and its importance’ along with our @ProofOfWitness team.

Somehow, it was one of the best events I’ve attended in a while. Zk’s usecases beyond blockchain is fascinating, and I plan to dive deep into Zk soon.

[Ashwin @ashwin_dev0x]

Just wrapped up ZK Witness: Pondicherry.

Repo is live with the circuits and a breakdown of @NoirLang architecture and its proving system, Barretenberg built by @aztecnetwork
🔗 https://t.co/BCKYuD0TkH

ZK Witness is growing into something real. Let’s keep building.

#ZKProofs

[ProofOfWitness @ProofOfWitness]

Then came the snacks, the networking & the proof photo

And ofc we minted our ZK Witness POAPs

Proof of Participation. On-chain.

Forever.

This isn’t just talks we’re building a real community of real builders
Next up?

[ProofOfWitness @ProofOfWitness]

2nd edition of ZK Witness wrapped in Pondicherry this weekend

From intro talks to hands-on ZK workshops, we brought together curious folks, devs, ZK believers

We kicked off with our ever-energetic host @Hari_priyoo

She opened the vibe, broke the ice, gave a quick intro.

[ProofOfWitness @ProofOfWitness]

Workshop time! 
@ashwin_dev0x took us straight into Noir with:
“Build Your First ZK Circuit in 30 Mins”

He demo’d how to build an age verification app with ZK

no scary math, just practical building.
The devs were loving it
