In a strategic move set to accelerate the development of next-generation blockchain infrastructure, Polygon Labs has announced a major hardware initiative focused on zero-knowledge (ZK) cryptography. As part of a broader collaboration with Fabric, a specialized hardware manufacturer, Polygon will purchase $5 million worth of server systems powered by custom-built verifiable processing units (VPUs) designed specifically for ZK-proof generation.
This advancement marks a pivotal step in scaling Ethereum’s layer-2 ecosystem through optimized cryptographic computation, with direct implications for the performance and interoperability of Polygon’s AggLayer—a protocol designed to unify multiple blockchains into a seamlessly connected network.
Advancing Blockchain Scalability Through Custom Hardware
Zero-knowledge proofs have emerged as one of the most promising technologies in modern blockchain architecture. By enabling one party to prove the validity of a statement without revealing any underlying data, ZK cryptography enhances privacy, security, and scalability across decentralized networks.
However, generating these proofs is computationally intensive. Traditional computing infrastructure often struggles to keep up with demand, leading to high costs and slow verification times—key bottlenecks in mass adoption.
To address this, Polygon Labs has partnered with Fabric, a startup focused on building application-specific integrated circuits (ASICs) tailored for cryptographic workloads. Their joint effort centers around the development of Verifiable Processing Units (VPUs)—a new class of chip engineered from the ground up to accelerate ZK-proof generation.

The Role of VPUs in ZK Proof Acceleration
Unlike general-purpose CPUs or even GPUs adapted for crypto workloads, VPUs are purpose-built for verifiable computation. They are optimized to run complex mathematical operations required by advanced proving systems such as Plonky2 and Plonky3, both developed by Polygon’s ZK research team.
These recursive proof systems allow for faster and more compact proofs, making them ideal for layer-2 scaling solutions. With Fabric’s VPUs, Polygon aims to drastically reduce:
- Time required to generate ZK proofs
- Energy consumption per proof
- Operational costs for validators and rollup operators
According to Mihailo Bjelic, co-founder of Polygon, "Fabric’s VPUs can accelerate the timeline for wider adoption of zero-knowledge technology from three to five years to six to 12 months." This dramatic improvement could bring real-time, affordable proofs—once considered years away—into immediate reach.
AggLayer: Building a Unified Blockchain Network
At the heart of this hardware investment lies AggLayer, Polygon’s ambitious interoperability framework. Designed to connect multiple layer-2 and layer-3 blockchains into a single cohesive system, AggLayer enables trust-minimized communication and asset transfers across chains without relying on third-party bridges.
By integrating VPU-powered servers into its infrastructure stack, Polygon aims to supercharge AggLayer’s proving capabilities. Faster proof generation means quicker finality, lower fees, and improved user experience across all connected chains.
The partnership goes beyond procurement. Fabric will collaborate directly with Polygon Labs to develop software that optimizes Plonky2 and Plonky3 libraries for VPU execution. Additionally, future iterations of the VPU will be co-designed to align with AggLayer’s long-term roadmap, ensuring sustained performance gains as network complexity grows.
Strategic Investment in Blockchain Infrastructure
Polygon Labs’ acquisition of $5 million in VPU-based server systems underscores its commitment to leading innovation in ZK infrastructure. Rather than relying solely on cloud computing or off-the-shelf hardware, the team is vertically integrating critical components of the tech stack—a move reminiscent of how major tech companies optimize performance through custom silicon.
This investment not only strengthens Polygon’s internal capabilities but also sets a precedent for how blockchain projects can leverage hardware specialization to overcome scalability limits.

Why This Matters for the Future of Web3
The convergence of hardware and blockchain software represents a paradigm shift in how decentralized systems scale. Historically, blockchain development has focused almost exclusively on protocol-level optimizations—consensus mechanisms, compression algorithms, and rollup architectures.
Now, with projects like Polygon pushing into custom silicon, we’re witnessing the dawn of hardware-aware blockchain design. This approach recognizes that software alone cannot solve all performance constraints; true scalability requires co-engineering both layers.
For developers and users alike, the benefits are tangible:
- Near-instant cross-chain transactions
- Drastically reduced gas fees
- Enhanced security via faster finality
- Greater accessibility due to lower operational overhead
Moreover, open-sourcing tools like Plonky3 ensures that advancements made through this collaboration can benefit the broader ecosystem—not just Polygon’s network.
