Today, Scroll, Axiom, is the developer Max Gillette The Ethereum Foundation's Privacy and Scaling Explorations (PSE) team announces OpenVM, an open source zkVM framework for instant proof.
OpenVM will be adopted by Scroll L2 as its zkVM, and plans to validate its main network blocks in the coming months. This moves the current Type 3 rollover to Type 1 zkEVM – the most equivalent zkEVM type in Ethereum.
Upgrade scroll to A Stage 1 A rollup of updates with a fully operational proof system will follow shortly thereafter.
According to a press release, Scroll's decision to design a new zkVM from the ground up was driven by the belief that many existing zkVM solutions were "monolithic" and "confined developers into vertically integrated stacks."
OpenVM's open source modular architecture enables Scroll to deliver features without making changes to the underlying circuitry, and enables developers to take advantage of zkVM improvements without having to modify the application code.
State of Zak
OpenVM joins an already crowded market with zkVMs. Unlike traditional virtual machines, zkVMs are designed to compile and execute smart contracts in zero-knowledge proofs in a secure and private way that does not reveal underlying data.
Today, the zkVM market carries at least a dozen different zkVM devices, such as the RISC Zero.risk0And “succinct.”SP1".
As shown in the chart below, proofs submitted to the Ethereum mainnet saw their peak in December 2023, and came largely from zk pools like Linea, ZKsync, and Scroll, rather than applications. Evidence volumes saw a decline in 2024, largely due to two factors.
First, batch proof generation has been increasingly used Recursive evidence collection — A technique that verifies multiple proofs within a single proof — to reduce costs.
Second, verification of evidence has become more efficient, so costs are very high decrease Only one year ago.
Prover networks, such as Risc Zero's "Boundless" and Fermah, have also helped batch applications and clusters reduce zk proof costs. These networks allow teams to outsource directory creation to specialized hardware providers who have ASIC hardware and GPUs that compete to create zk directories on the cheap.
Based on electrical capital Latest developer reportThere are 2,054 monthly active developers working at zk. The use of zk has seen tremendous growth, with zk contract deployments increasing from 40 to 639 today over the past four years.
