The Ethereum Basis has set a twelve-month clock operating on one of the crucial audacious upgrades within the community’s decade-long historical past: changing full block re-execution with real-time verification of succinct zero-knowledge proofs native to Layer 1. “Ethereum goes all in on ZK,” analysis engineer Sophia Gold declared in a July 10 weblog publish that sketches the trail to an L1 zkEVM able to dealing with reside main-net visitors with out compromising decentralization or safety.
Ethereum Goes All-In On ZK
Gold’s plan begins by letting validators choose into so-called “ZK purchasers.” As a substitute of replaying transactions, these purchasers will “statelessly confirm” three unbiased proofs—every produced by a distinct zkVM mirroring the EVM—to attain the identical defence-in-depth that consumer range gives as we speak. Proof verification is fast sufficient, and the artefacts compact sufficient, that downloading a number of proofs per block is “very affordable,” she wrote.
For the primary launch the heavy cryptography can run off-chain, supplied the Glamsterdam hard fork introduces pipelining to purchase provers a couple of additional seconds. As soon as a super-majority of stake is snug, gas limits will rise to ranges that make proof verification, slightly than re-execution, a {hardware} necessity. Those self same proofs can then feed an EXECUTE precompile, opening the door to native zk-rollups.
To forestall bottlenecks, the Basis proposes a strict “real-time” proving goal: ninety-nine p.c of main-net blocks should be proved in ten seconds or much less—nicely inside the twelve-second slot time minus propagation overhead. Proof programs should hit 128-bit safety and keep below 300 KiB with out trusted recursive wrappers, although a brief ground of 100 bits is tolerated through the first months.
A parallel effort focuses on “house proving.” Gold argues that some solo stakers operating validators from their residing rooms must also have the ability to generate proofs, offering a ultimate bulwark in opposition to censorship. The Basis subsequently caps on-premise capital expenditure at $100,000—simply above as we speak’s 32-ETH stake—and limits energy draw to 10 kW, a load appropriate with residential EV chargers. “Greater than {hardware} value, essentially the most important constraint for house proving … is vitality utilization,” she famous.
The announcement lands amid a break-neck zero-knowledge arms race. Final month Succinct’s open-sourced SP1 Hypercube zkVM proved 93 p.c of 10,000 reside Ethereum blocks in a mean 10.3 seconds, edging contained in the Basis’s latency envelope—albeit on a GPU cluster costing roughly $300,000–400,000.
Between now and Devconnect Argentina in mid-November, the Basis expects zkVM groups to drive these figures right down to the purpose the place proofs might be minted on a single rack and verified virtually immediately by each validator. Gold framed the competitors as a “race to real-time,” one whose end line will see Ethereum remodeled into “by far the biggest ZK utility on the planet.”
Ought to the roadmap maintain, 2026 may open with an Ethereum mainnet the place each block, transaction and smart-contract name is vouched for by cryptographic certainty slightly than costly re-execution—a radical shift that guarantees larger throughput, decrease {hardware} boundaries and new on-chain privateness primitives, all with out splitting the chain or compromising its core ethos of trustless computation.
At press time, ETH traded at $2,984.
