- Plonky3 will bring modular flexibility and an improved proving system.
- It seeks to accelerate the development of zero-knowledge systems in the Polygon network.
- Developers will be able to build bespoke systems for zk-VMs and zk-EVMs
Researchers at Polygon Labs, the firm behind the Polygon network, have announced the production readiness of Plonky3, the latest version of its zero-knowledge proving system.
According to a Polygon blog post, Plonky3 is more flexible and dynamic. It allows developers to build bespoke systems for zk-VMs or zk-EVMs that can be extensively modified to suit specific use cases and applications. The firm said the software is open-source and under MIT and Apache licenses.
All in all, Plonky3 is a significant step up from Plonky2, which was launched two years ago. Despite Plonky2 becoming a widely adopted ZK proving system, it didn’t have the generality that Polygon wanted, as it had a lot of fixed properties.
On the other hand, Plonky3 delivers an open-source toolkit for developers to build use-case-specific zk-VMs or zk-EVMs with extensive cryptographic security.
Polygon Fully Embraces Zero-Knowledge
Polygon is not shy about its belief in zero-knowledge technology and the benefits it can bring to Ethereum and the decentralised finance (DeFi) sector.

In the official blog post, the protocol stated:
No other scaling technology can do what ZK can do. Cryptographic security, at speed; recursion, for efficiency; and the ability to unify liquidity and state across a web of sovereign chains that’s simply not possible otherwise.
Polygon In the context of ZK-rollups, a proving system refers to a cryptographic mechanism used to generate and verify the validity proofs submitted to the main blockchain. Proving systems usually rely on a prover and a verifier.
The prover can use different types of Zero-knowledge proofs (ZKPs) techniques, such as zk-SNARKs or zk-STARKs, to ultimately generate the cryptographic proof.
zk-EVMs
As Vitalik Buterin explains in his article titled The Different Types of ZK-EVMs, the main obstacle to zero-knowledge rollups is the lack of EVM compatibility.
Zero-knowledge Ethereum Virtual Machine (zk-EVM) refers to a virtual machine capable of executing smart contracts while being compatible with Zero-knowledge proof computation and the Ethereum infrastructure.
In simpler words, they are a type of layer-2 that uses Zero-knowledge rollups but is also compatible (or somewhat compatible) with the Ethereum infrastructure.

Meanwhile, Zero-knowledge Virtual Machines (zk-VMs) refer to more general-purpose systems that also use ZKPs. The main difference between the two is that zk-VMs focus on providing general scalability and privacy, while zk-EVMs are specifically designed for the Ethereum blockchain.
Overall, zk-EVMs have become a popular narrative in the crypto world, with many protocols like Linea and Scroll amassing US$
