Scroll announces OpenVM, a new zkVM

It is a phase from the 0xResearch e-newsletter. To learn the total editions, subscribe.

Right this moment, Scroll, Axiom, developer Max Gillet, and the Ethereum Basis’s Privateness & Scaling Explorations (PSE) staff introduced OpenVM, an open-source zkVM framework for immediate proofing.

OpenVM will likely be adopted by the Scroll L2 as its zkVM and plans to validate mainnet blocks within the coming months. This transitions from a at present Sort-3 to a Sort-1 zkEVM – essentially the most totally Ethereum equal zkEVM kind.

Scroll’s improve to a Stage-1 rollup with a completely functioning pilot system will comply with shortly afterwards.

Based on a press launch, Scroll’s choice to design a brand new zkVM from the bottom up was pushed by the idea that many current zkVM options have been “monolithic” and “locked builders into vertically built-in stacks.”

OpenVM’s open-source and modular structure would enable Scroll to introduce options with out making adjustments to the underlying circuitry, and builders might benefit from zkVM enhancements with out having to vary the appliance code.

The state of ZK

OpenVM joins a market already filled with zkVMs. Not like conventional digital machines, zkVMs are designed to compile and execute good contracts into zero-knowledge proofs in a safe and personal method that doesn’t reveal any underlying information.

Right this moment, the zkVM market contains at the least a dozen totally different zkVMs, resembling RISC Zero “RISC0” and Succinct’s “SP1.”

As proven within the chart under, proofs submitted to the Ethereum mainnet peaked in December 2023, largely coming from zk rollups like Linea, ZKsync, and Scroll, fairly than purposes. Trial volumes declined in 2024, largely on account of two components.

First, proof technology is more and more achieved in batches utilizing recursive proof aggregation – a way that verifies a number of proofs inside a single proof – to scale back prices.

Second, proof verification turns into extra environment friendly, considerably lowering prices in comparison with only a 12 months in the past.

Proof networks like Risc Zero’s “Boundless” and Fermah have additionally helped apps and rollups drive down the price of ZK testing. These networks enable groups to outsource proof technology to specialised {hardware} distributors with ASICs and GPUs that compete to generate zk proofs cheaply.

Based mostly on Electrical Capital’s current developer report, there are 2,054 lively builders working in zk each month. Using zk has seen super development, with the variety of zk contract implementations rising from 40 over the previous 4 years to 639 right now.
