Polygon Labs, the creator of the Polygon network, has put forward a proposed architecture for its upcoming project called “Polygon 2.0.” In a recent blog post, the team outlined a vision for the project, suggesting that it should consist of four layers that will be interconnected with Ethereum. The team also proposed the inclusion of an aggregator bridge that will facilitate near-instant and atomic bridge transactions if approved by validators.

Summary

Polygon Labs has presented an architecture proposal for its project, Polygon 2.0. The proposal outlines the inclusion of four layers that will be connected through Ethereum, along with the introduction of an aggregator bridge for improved bridge transactions. If approved, Polygon 2.0 aims to achieve unlimited scalability and unified liquidity.

The team initially revealed Polygon 2.0 on June 12, claiming that it would establish the “value layer” of the internet. However, detailed information was limited at that time. On June 20, co-founder Mihailo Bjelic suggested upgrading the current Polygon network to incorporate zero-knowledge proofs, which are essential for aligning the old network with the vision of Polygon 2.0.

In its recent blog post on June 30, Polygon provided further insights into the proposed architecture of Polygon 2.0. The project will be based on a foundational staking layer, which is already in existence. This layer includes a validator manager contract on Ethereum and a chain manager contract for each individual Polygon chain. New Polygon chains can be established by launching new chain manager contracts on Ethereum.

Additionally, Polygon 2.0 will have an interoperability layer that connects all Polygon chains through bridges, utilizing zero-knowledge proofs for validation. The interoperability layer will feature an aggregator that combines individual zero-knowledge proofs from each bridge into one proof before sending it to Ethereum. The aim is to enable seamless bridge transactions and reduce Ethereum gas consumption for proof verification.

The project will also include the current execution layer, which relies on the Erigon Ethereum client, and a proving layer that standardizes the zero-knowledge proof process across all Polygon chains. Further details about each layer will be provided in the future, as announced by the Polygon team.

Polygon is not the only network aiming to expand into a multichain ecosystem. Another project called zkSync Era plans to create a network of “Hyperchains” and hopes to launch them in a testnet phase by the end of the year. Optimism is also working on creating a “Superchain” in collaboration with Coinbase’s Base network and recently implemented the “Bedrock” upgrade to facilitate this transformation.

FAQ

What is Polygon 2.0?

Polygon 2.0 is an upcoming project proposed by Polygon Labs that aims to establish the “value layer” of the internet. It will consist of four interconnected layers and feature an aggregator bridge for improved bridge transactions.

What are the four layers of Polygon 2.0?

The four layers of Polygon 2.0 include the foundational staking layer, the interoperability layer, the execution layer, and the proving layer. Each layer has specific functions and contributes to the overall architecture of Polygon 2.0.

How will the aggregator bridge work in Polygon 2.0?

The aggregator bridge in Polygon 2.0 will combine individual zero-knowledge proofs from each bridge into one proof before sending it to Ethereum. This will enable near-instant and atomic bridge transactions and reduce Ethereum gas consumption for proof verification.

What are some other projects aiming to create a multichain ecosystem?

Some other projects working towards a multichain ecosystem include zkSync Era, which plans to create “Hyperchains,” and Optimism, which is collaborating with Coinbase’s Base network to create a “Superchain.”
