ZKsync Prover Hits 10-Second Proof Speed on Ethereum
ZKsync's new proving system verified thousands of Ethereum blocks in seconds, using just one consumer graphics card. For everyday wallet users, this breakthrough could mean faster transaction finality and cheaper fees across rollups, long before most people notice any change at all.
What actually happened
ZKsync unveiled Airbender Prime on 17 October 2026, according to Wu Blockchain. A single NVIDIA RTX PRO 6000 Blackwell GPU proved a consecutive run of 7,200 Ethereum mainnet blocks. 99% of those proofs finished in under 10 seconds, and every block, including witness preparation, finished within 12 seconds. The system runs on the open RISC-V architecture and relies on hash-based STARK proofs, designed to resist quantum attacks. It also comes with a separate verifier so outside parties can check results independently. Ethereum co-founder Vitalik Buterin praised the team, calling the proof-speed race effectively settled. He said attention must now turn fully toward security rather than raw performance.
How we got here
Zero-knowledge proofs let rollups confirm Ethereum transactions without rerunning every computation, cutting costs and speeding up finality. For years, zkEVM teams competed almost entirely on proving speed, since slow proofs delayed withdrawals and raised costs for users. Airbender Prime's benchmark, near-instant proofs on ordinary hardware, now ranks among the fastest public results for an Ethereum-equivalent prover. Buterin outlined three remaining tasks: confirming the proof system matches Ethereum's exact rules, fixing cost limits tied to gas usage, and verifying the cryptography itself holds up. That shifts the entire zkEVM contest from a speed race into a security audit.
Why this matters for you
For people using bonuz wallets or any zk-rollup, faster proving could eventually mean quicker transfers and smaller fees, assuming networks adopt similar technology. For developers building on Ethereum-style rollups, Buterin's comments set a new expectation: security guarantees now matter more than leaderboard speed. Teams that skip formal verification may face more scrutiny from users and auditors alike. Holders of assets on zk-rollups should watch which projects invest in mathematical proof correctness, since that reduces the risk of a prover bug draining funds. For everyday users, the real benefit will arrive once these improvements quietly reach the wallets and apps they already use.
The bigger question
If raw speed no longer decides which zkEVM wins, what new benchmark will take its place? Formal verification can confirm a system behaves exactly as designed, but it cannot promise every real-world attack has been considered. For an industry now moving billions through rollups, who ultimately decides a prover is safe enough to trust with everyday savings and transactions today?
What to watch
ZKsync has not set a mainnet launch date for Airbender Prime. Watch for Ethereum core developers to respond to Buterin's security roadmap in coming weeks. Rival zkEVM teams may release their own benchmarks as the industry pivots toward audits. Bonuz is tracking this shift, since faster, cheaper proof verification could eventually support lightweight devices like smart glasses.
