[Zenith @ZenithFdn]

Zenith is expanding and we're hiring two people to grow with us.

> Business Development Associate: shape Zenith's launch by managing inbound client relationships, qualifying partnerships, and building the workflows that keep everything moving. You're organized, relationship-driven, and fluent in both Web3 and institutional finance conversations.
https://t.co/xEg65zmUXO

> Head of Security (Engineering): own security end-to-end across our full stack. This is a deeply technical role: threat modeling, vulnerability research, incident response, secure architecture from blockchain protocol layer to cloud infrastructure.

If you want to work at the forefront of where DeFi meets institutional finance with an ambitious team playing the long game, we'd love to hear from you.

Zth.

Canton builders in Cannes ☕️

Joined the @CantonFdn x @ZenithFdn Builders Breakfast at EthCC this morning - great conversations about where institutional DeFi is heading.

Find us if you're here 😉

[Henri Kämäräinen @Henrixbor]

Time to clear our Social calendars. @CantonNetwork, @zenithfdn, it's time to cook.

[Zenith @ZenithFdn]

They told us it was impossible. We did it anyways. Today we announce Zenith.

POV: You wake up H2 2026 and Ethereum‘s application layer has fully teleported into Wall Street’s blockchain of choice. We are that protocol, now opening a direct on-ramp between the world’s largest programmable and institutional blockchain ecosystems.

breakthrough by @thezkcloud :)

→ Fetching Ethereum block data to feed into zkVMs used to take minutes.
→ ZkCloud slashed that by 1,000x — from hundreds of seconds to hundreds of milliseconds.
→ The trick? A custom fetcher using Reth's debug_executionWitness. Open source soon™.

Time spent outside proving for block 22,795,300:

🥇 ZkCloud: 3s 😎
🥈 Succinct: 117s
🥉 Cysic: 298s
4️⃣ Brevis: 311s
5️⃣ Snarkify: 317s
6️⃣ ZKM: 365s

[Henri Kämäräinen @Henrixbor]

In Cannes for EthCC? Come say hi! 😃

[Henri Kämäräinen @Henrixbor]

ZK could be the next major meta-play that has yet to gain widespread attention. I can’t help but wonder about the opportunity cost many might face by not delving deeper into ZK now if we simply let things unfold.

[Henri Kämäräinen @Henrixbor]

@thezkcloud It does feel like the start of a new era is on the horizon☁���

[Henri Kämäräinen @Henrixbor]

@teemupai @jur7v2 @HeslinKim @jur7v3 Feel free to reach out to me on discord on tg to discuss more :)

[Henri Kämäräinen @Henrixbor]

Bitcoin hits 100k, and the Firestarter launch happens on the same day. Coincidence? I don't think so.

[Julia Suontama @SuontamaJulia]

Funny thing I've noticed since diving into Web3 this summer: coming from the outside, I'm constantly amazed at how sharp people are. The way they think is next-level. No one takes anything at face value—they question, explore different angles, and come up with the most out-of-the-box solutions.

Makes me wonder where this mindset comes from.

Eager to meet these folks again this week when heading to #DevCon2024

See you at zk events and rAAVE!
Few #zeroknowledge events to join:

[zerokn0wledge.hl 🪬✨ @zerokn0wledge_]

For the first time ever, @aztecnetwork blocks were ZK proved by third parties in its ProverNet contest, aiming to test provers ability to produce the proofs necessary validate Aztec blocks.

15 teams stepped up to the challenge and produced Aztec blocks over several days, competing in two categories (custom and generic)

Now, the results are in. ⤵️

Custom:

➊ @gevulot_network

Generic*:

➊ @gevulot_network (avg time: 419s)
➋ @MarlinProtocol (avg time: 430s)
➌ @lagrangedev (avg time: 483s)
➍ @Ember_Stake (avg time: 604s)

* ) four teams tied, proving all eligible blocks in time

Great to see @aztecnetwork pushing towards prover decentralization and how strong these teams have performed!

[Norbert Vadas @NorbertVadas]

Come and meet @gevulot_network in Singapore next week.

[Norbert Vadas @NorbertVadas]

Coming to Montreal for @__zkhack__ ?
Check out the bounties of @gevulot_network !

Bounty #1: Port a ZK-rollup prover to Gevulot
Hint: @zksync 's prover or @StarkWareLtd 's Stwo might be great candidates.

Tfw you’re used to crypto asset liquidity, but then you go try to buy stocks in a local stock exchange and discover that multibillion dollar companies have less than 100K€ order book depth. Also seemingly no market making.

Wtf is tradfi doing?

Something is brewing..

[Tπ @vectordrift]

I think the decentralised prover network market dynamics will end up looking a lot more like web2 cloud market dynamics than people are expecting.
