This GPT Image 2 prompt is going insanely viral right now. “Redraw the attached image in the most clumsy, scribbly, and utterly pathetic way possible. Use a white background, and make it look like it was drawn in MS Paint with a mouse. It should be vaguely similar but also not really, kind of matching but also off in a confusing, awkward way, with that low-quality pixel-by-pixel feel that really emphasizes how ridiculously bad it is. Actually, you know what, whatever, just draw it however you want.”

a bit of @rive_app animation feels nostalgic as an old geezer that started with Flash… when it was Macromedia 👴

The Superchain is going ZK! We're honored to partner with @Optimism to bring ZK to the Superchain, starting with OP Mainnet. Succinct now covers 90% of the rollup market. The infrastructure layer for ZK is consolidating and we're at the center.

Big day for the Superchain. 🔴✨ We’re 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 — and withdrawals are about to get faster. Here's what that means. ⸻ 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. ⸻ 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. ⸻ WHY SUCCINCT Their proving system works — 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 — sequencer, batcher, op-node — stays the same. We built the OP Stack to be modular for exactly this reason. ⸻ 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. ⸻ 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 ⸻ 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. We’re 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: optimism.io/blog/optimism-pa…
