The global digital economy can’t run on a single mega-chain.
Banks, businesses, and institutions will operate their own chains, private where needed, and connect directly via ZK proofs, not intermediaries.
This requires high performance & real-time proofs.
Atlas delivers both.
Atlas combines:
✦ A new ultra-high performance sequencer
✦ A new EVM-equivalent execution environment optimized for ZK
✦ Airbender, the world’s fastest open source RISC-V prover
The Atlas sequencer delivers 15K+ TPS on stablecoin transfers.
That’s 2× VISA’s annualized avg. load, giving businesses and institutions confidence they can scale onchain.
Airbender proves transactions for as little as $0.0001/transfer.
To put it in perspective: a single modern GPU can sustain >1M tx/day at that cost (less than $100/day for Ethereum-grade security).
This ability to run proofs on in-house infrastructure is especially relevant for private chains that must keep data local - for compliance, privacy, or regulatory needs.
Finally, the most consequential aspect of Atlas is what we call 1-second ZK finality.
Each block is proven by Airbender in about a second, and then committed to the ZKsync Gateway - the coordination layer linking all ZK Chains together.
What does that mean in practice?
Within one second of a user sending a tx, the entire network of chains can verify its correctness. The proofs carry trust between domains.
This is what enables seamless interoperability on ZKsync.
Legacy 3rd party bridges put heavy limits on UX: they rely on external liquidity, support only the most liquid tokens, and often require costly routing. Sometimes transactions can’t go through at all.
With interop based on 1-second ZK finality, none of that applies. You send funds from one ZK Chain to another, the block is proven and committed to the Gateway in ~1 second, and those funds are immediately usable on the receiving chain.
Any size. Any asset. Any network.

Ready to prove Ethereum in seconds on a single GPU?
Introducing ZKsync Airbender:
The world’s fastest open-source RISC-V zkVM ⚡️
On an H100 GPU Airbender reaches ~21.8 MHz base proving speed on a standardized benchmark, followed by 3.45 MHz for SP1 Turbo and 1.1 MHz for RiscZero.
Airbender is ~6x faster than the closest contender.
Powered by Airbender, ZKsync OS (our new zkEVM execution environment) is proving Ethereum blocks end-to-end in under 35 seconds on a single GPU.
This opens the door for truly decentralized at-home proving.

When you send a transaction on any rollup, it’s not “final” immediately. Rollups derive their security from Ethereum, which means Ethereum needs to finalize your transaction. This happens when the rollup sends data and a proof of that data to an Ethereum smart contract to finalize.
⚖️ Execution delays for Optimistic Rollups are several days to account for their challenge period.
➕ Execution delays for ZK Rollups are very short due to ZK-proofs. However, most core teams extend this period as an added security measure.
Why is ZKsync’s execution delay currently 21 hours?
ZK rollups have shorter execution delays because they use zero-knowledge proofs for transaction validation (trust math, not validators). However, core teams often extend this period as an added security measure.
@the_matter_labs introduced this execution delay to ZKsync so the team could investigate and respond to anomalies such as rapid outflow or unusually large withdrawals.
.@NethermindEth and @the_matter_labs just completed the first formal verification of ZKsync's on-chain zk-verifier. This is a major milestone for ZKsync and blockchain security.
So, what does this mean? 🧵👇
2/10 What is a zk-verifier?
The zk-verifier ensures that ZK rollups process transactions correctly. It checks the correctness of zero-knowledge proofs, which are central to making rollups scalable and efficient.
3/10 Why is this important?
If a verifier has errors, it could make the system vulnerable to attacks. But since verifiers are complex, ensuring their accuracy is no simple task. So, how can we confidently verify that transactions are not vulnerable to errors?
