  • Polygon Labs introduced the “type 1 prover” to enable seamless integration of zero-knowledge (ZK) scaling solutions into Ethereum Virtual Machine (EVM) compatible chains, enhancing blockchain scalability and efficiency without requiring hard forks or client modifications.
  • Alongside the type 1 prover, the AggLayer interoperability protocol is launching, aimed at connecting blockchains within the ecosystem to foster interoperability, unified liquidity, and enhanced security through the aggregation of ZK proofs.

In an innovative stride towards blockchain scalability and efficiency, Polygon Labs recently unveiled its latest technological breakthrough: the “type 1 prover.” 

The pioneering technology stands to revolutionize the way Ethereum Virtual Machine (EVM) compatible chains integrate zero-knowledge (ZK) scaling solutions, marking a significant leap towards broader adoption of validium networks for proof verification and settlement on the Ethereum blockchain.

Polygon Labs advancing blockchain scalability with type 1 prover

Polygon Labs’ introduction of the type 1 prover represents a pivotal advancement in blockchain technology, enabling EVM chains to seamlessly adopt ZK proofs without the need for hard forks or modifications to existing clients. Set to be released later the year and integrated into Polygon’s Comprehensive Development Kit (CDK), the technology supersedes the project’s previous type 2 proving mechanism by offering compatibility across a wide array of EVM chains.

Brendan Farmer, a co-founder of Polygon, emphasized the type 1 prover’s ability to generate zero-knowledge proofs for any EVM chain, thereby facilitating a smooth transition for these networks into validiums. Validiums are specialized Layer 2 networks that leverage ZK proofs to enhance transaction efficiency and reduce costs, storing only ZK-proofs on the Ethereum mainnet while keeping actual transaction data off-chain, bolstered by a data availability solution. The approach offers a stark contrast to ZK-Rollups, which necessitate the publication of proofs of app data on the Ethereum mainnet as well.

The transition to ZK-based networks

The shift towards ZK-based networks, such as validiums and ZK-rollups, presents numerous benefits for Layer 2 projects, particularly in addressing the limitations associated with optimistic rollup solutions. Notably, optimistic rollups, including platforms like Optimism and Arbitrum, impose a seven-day withdrawal delay, imposing additional time and financial burdens on users. Farmer pointed out the inefficiencies in the system, highlighting the excessive costs borne by users due to reliance on third-party bridges for transactions.

By adopting a ZK-based network, projects can eliminate these delays and unnecessary costs, streamlining the user experience. Polygon Labs aims to support the transition, offering projects the flexibility to become full-fledged ZK-rollups using their type-1 prover. Ultimately, the decision rests with the teams behind these projects, underscoring the customizable nature of Polygon’s technological offerings.

Enhancing interoperability and security with AggLayer

In tandem with the rollout of the type 1 prover, Polygon Labs is set to launch the first version of its interoperability protocol, the AggLayer, in February. The protocol aims to connect blockchains within the ecosystem, fostering interoperability and unified liquidity for Layer 2 solutions. The AggLayer will play a crucial role in the forthcoming Polygon 2.0 network, aggregating ZK proofs from all connected chains to ensure uniform security across both modular and monolithic chains.

The introduction of AggLayer signifies a strategic effort to enhance the security and efficiency of the blockchain ecosystem. Unlike conventional interoperability solutions, AggLayer’s unique capability to aggregate ZK proofs promises a more cohesive and secure network, paving the way for the next iteration of the Polygon network.


Polygon Labs’ unveiling of the type 1 prover and the forthcoming launch of AggLayer mark significant milestones in the evolution of blockchain technology. By enabling EVM-compatible chains to integrate ZK scaling solutions more effectively, Polygon Labs is not only enhancing the scalability and efficiency of these networks but also paving the way for a more interconnected and secure blockchain ecosystem. As the blockchain community anticipates the release of these technologies later in the year, the potential for innovation and growth within the space is boundless. With a focus on reducing transaction costs, eliminating unnecessary delays, and ensuring robust security across the network, Polygon Labs continues to lead the charge in advancing blockchain technology for a more efficient and interconnected future.
