Polygon Labs, the creator of the Polygon (MATIC) network, has proposed an architectural plan for its upcoming project called “Polygon 2.0.” The project aims to establish a web of interconnected networks, forming the “Value Layer of the Internet.” The newly presented architecture consists of four layers, including an aggregator bridge that enables near-instant and atomic bridge transactions.
Initially announced on June 12, Polygon 2.0 seeks to transform the existing Polygon network into a scalable and unified liquidity solution. Co-founder Mihailo Bjelic further elaborated on June 20, stating that implementing zero-knowledge proofs (ZK proofs) would be crucial to align the old network with the vision of Polygon 2.0.
Architecture of Polygon 2.0
The recently published blog post on June 30 provides more in-depth insights into the structure of Polygon 2.0. The foundation of the project lies in the existing staking layer, which includes a validator manager contract on Ethereum and a chain manager contract for each individual Polygon chain. New Polygon chains can be created by launching new chain manager contracts on Ethereum.
The interoperability layer connects the foundational staking layer and features bridges connecting each Polygon chain through Ethereum. Zero-knowledge proofs are utilized to validate all transfers, ensuring security. Additionally, an aggregator within this layer combines ZK-proofs from each bridge into one proof before sending it to Ethereum. This streamlines bridge transactions and reduces Ethereum gas consumption for proof verification.
Polygon 2.0’s third layer encompasses the current execution layer, relying on the Erigon Ethereum client. The fourth layer, known as the proving layer, standardizes the ZK-proof process across all Polygon chains. Further details about each layer will be revealed at a later date.
Expanding into a Multi-chain Ecosystem
Polygon is not the only network attempting to expand into a multi-chain ecosystem. Other projects, such as zkSync Era and Optimism, are also exploring similar concepts, aiming to create interconnected networks or “Hyperchains” and “Superchains,” respectively.
The architecture proposed by Polygon for Polygon 2.0 showcases their commitment to scalability and interoperability within the blockchain space. By leveraging ZK proofs and an aggregator bridge, Polygon aims to enhance the efficiency and accessibility of transactions across its network of interconnected chains.
