Imagine a future where ZK is more secure, more performant, and ready to scale without compromise. That’s the future we’re building at ZisK. ⚡️🫡
Jordi Baylina (@jbaylina) x @ziskvm has helped build across donations, independent infrastructure, digital identity and cryptography. Now working on ZisK, Jordi Baylina develops open-source infrastructure for zero-knowledge proofs: tools that let software verify claims while limiting what information needs to be disclosed. That experience matters beyond blockchain development. More private credentials and independently verifiable systems need foundations other people can inspect and build upon.

Atomic synchronous composability is no longer a promise. History made on mainnet: the first atomic cross-chain L1->L2 transaction ever 🔥 And this is only the beginning for EEZ ... 🚀 @etheconomiczone

Ethereum mints ~33,800 ETH ($80M) a year so light clients can trust 512 validators I'm proving every epoch over all 901,832 validators for $4,116 a year in one GPU in <30 sec w/ @ziskvm Live in mainnet now.

We're excited that GnosisDAO approved GIP-153 by a landslide, putting Gnosis Chain on a path from a standalone L1 to an EEZ rollup settling on Ethereum. 🔥 Being first onto EEZ gives Gnosis Chain synchronous composability with Ethereum, something no existing L2 offers: the one axis where Gnosis Chain competes on its own terms, plus a first-mover seat in the emerging EEZ deployment market.
GIP-153 has passed. Gnosis Chain becomes the first Ethereum Economic Zone instance. This will see synchronous composability with mainnet, something no L2 currently offers, whilst Gnosis optimizes to become a consumer-friendly ecosystem. We will build with Ethereum, not on Ethereum. snapshot.org/#/s:gnosis.eth/…

Ethereum's fragmentation problem just got its most serious answer yet. The Ethereum Economic Zone, led by Gnosis and ZisK, funded by the EF. The goal: SYNCHRONOUS composability for the L1 and its L2s, so one transaction can execute cleanly across multiple chains. > Right now your coins on L2s can't interact with contracts on L1 or other L2s without bridging. Costs money, costs time, fragments liquidity. The EEZ ends that > Rollups plugged into the EEZ can call contracts on L1 or other L2s and receive a response in a SINGLE transaction. It feels like you're using one chain > This doesn't require any Ethereum protocol-level changes. The entire system runs on smart contracts + real-time ZK proving > Gnosis isn't some unknown team. They built CoW Protocol, Safe multisigs, the Conditional Tokens format underpinning Polymarket, Gnosis Chain, Gnosis Pay. ZisK brings an efficient open-source zkVM for real-time proving > NO ONE owns the stack. The EF is funding this as credibly neutral shared infrastructure. Free and open source for all Imagine an Aave position on Ethereum interacting with a Uniswap pool on Unichain in a single transaction. That'd be beautiful. That's the EEZ.

Welcome to the Ethereum Economic Zone (EEZ), a framework for synchronously composable rollups. What does that mean? One deployment. Shared liquidity. Single transactions across L1 & L2. Identity verified anywhere. Smart wallets connected everywhere. No additional trust assumptions. This means L2s that are as credibly neutral, economically aligned, and publicly governed as the base layer itself. EEZ furthers Ethereum as the leading decentralized economy.

ZisK v0.15.0 moves the system to 128-bit proven security without increasing proving time. This is enabled primarily by a new Keccak arithmetization. The Keccak optimization offsets the additional cost introduced by stronger recursion and verification constraints, allowing end-to-end proving performance to remain comparable to v0.14.0, while reducing the final proof size to ~240 KB.

ZisK was recently featured by @drakefjustin during the @eth_proofs demo [ youtube.com/live/IbXLIcCK-6Y…] Real-time Ethereum proving on our Girona cluster (16×5090) reflects the principles we build around: security, performance, and open-source integrity. We’re grateful to @drakefjustin and @eth_proofs for the standards that continue to guide the ecosystem. Our team remains committed to the values that define Ethereum, and we’ll keep building with the same focus. If you’re exploring zkVMs or proving systems, we’re always up for a thoughtful conversation.

A friend asked me what I thought about the gun debate and I said I was pretty firmly in the "tighter gun laws" camp, but that I was also for sure on Child's Hill about this. Then I realized that acknowledging being on Child's Hill meant I was actually in Insecure Canyon.

There is an important vulnerability in the snarkJS plonk implementation that affects this smart contract. We will disclosure and push the fix very soon. But please remove your funds from this smart contract before it’s too late. Please RT
