For the past 5 months several unwell people @LidoFinance have been trying to build the most private AI imaginable. Today I'm opening the waitlist.
Wisp (@usewisp_io) is the antithesis to Sam and Dario's 'trust me bro' privacy. Architected so no one - even Wisp - can read, train on or retain your data.
Waitlist: https://t.co/3xFnn3TNO8
How it works:
@devanshmehta Obviously depends on where you are, but service workers in the US are usually very nice to me. I have an idea though why your experience might be different
Big day for the Superchain. ๐ดโจ
Weโre integrating ZK more deeply into the OP Stack, and are excited to announce that @SuccinctLabs is our first preferred proving partner in this area. Validity proofs are going โ and withdrawals are about to get faster.
Here's what that means.
โธป
THE 7-DAY PROBLEM
Optimistic rollups have a 7-day challenge window. Anyone can challenge a bad state transition during that period. For most users, this is abstracted away with app-layer bridges.
For institutions? Different story.
Custody providers can't lock capital for a week every time they move funds off L2. Market makers need capital efficiency across positions. Treasury teams need faster withdrawal finality that matches traditional infrastructure expectations.
The 7-day window was always a tradeoff. Now we're addressing it.
โธป
ZK CHANGES THE MATH
With validity proofs, we don't wait for challenges. We prove the state transition cryptographically. When the proof verifies on L1, the withdrawal is final.
The goal: instant, real-time withdrawals.
โธป
WHY SUCCINCT
Their proving system works โ fast proving, low costs, compatible with our existing architecture. @SuccinctLabs secures billions in TVL across the ecosystem.
OP Succinct, their proving engine for the OP Stack, is a drop-in upgrade. Deploy one smart contract, spin up a lightweight proposer service. Everything else โ sequencer, batcher, op-node โ stays the same.
We built the OP Stack to be modular for exactly this reason.
โธป
THIS ISN'T ABOUT CHEAP TRANSACTIONS
L2s were never just "cheaper Ethereum." That framing missed it.
The best Superchain deployments aren't discount L1s. They're doing things L1 structurally can't:
* Sub-200ms blocks for real-time apps
* Embedded distribution (Base: 110M Coinbase users)
* Custom sequencing for specific use cases
* Native identity infrastructure (World Chain)
* Exchange-integrated DeFi (Ink)
These bring real users, real distribution, real use cases that didn't exist before.
ZK validity proofs unlock real economic efficiency for users & institutions.
โธป
WHAT THIS UNLOCKS
* Custody providers can move client assets without locking capital for a week
* Market makers gain capital efficiency across L2 positions
* Treasury operations get faster withdrawal finality, matching expectations from traditional infrastructure
โธป
MULTI-PROOF FUTURE
This is step one.
The vision: OP Stack chains choose the prover networks that fits their needs. Different security tradeoffs, different cost profiles. Modular infrastructure, sovereign choices.
After ZK goes live on OP Mainnet, every OP Stack chain can upgrade seamlessly. Weโre bringing fast withdrawals with strong cryptographic security to the Superchain!

The OP Stack was designed for this moment! ZK for your Blockchain. Your Revenue. Enterprise Guarantees.
Thanks to @SuccinctLabs and @pumatheuma for building what we needed.
Full announcement: https://t.co/Co0tyEvwtd
Messari report is out - The OP Stack processed 3.6 billion transactions in H2 alone. That's 13% of all transactions in crypto.
All the new L1s will learn the lessons we did 4 years ago. Performance optimizations are not differentiators.
The OP Stack is the peak of customizability. You really have to be, in order to enable such vastly different businesses & business models to succeed:
@base โ consumer adoption at scale
@unichain โ DeFi trading infrastructure
@worldcoin โ identity for 20M+ verified users
@soneium โ creators and entertainment
@inkonchain โ institutional DeFi
@Celo โ mobile payments
Plus @OKX migrating XLayer to OP Stack, @Official_Upbit launching @giwa_io, @EYnews deploying Nightfall for enterprise privacy.
All working because we set our roadmap based on what our partners need, not what's trending.
Your blockchain. Your revenue. Enterprise guarantees.
More at Scaling Summit next week.
