Polygon Labs has revealed the proposed architecture for the next iteration of the layer 2 Ethereum network of the same name. Polygon 2.0 is formalized as a set of protocols designed to work together.
1/ Today, we are excited to propose the Polygon 2.0 architecture, designed to provide unlimited scalability and unified liquidity, thus transforming Polygon into the Value Layer of the Internet!

The developers proposed four levels, each of which provides its own part of the processes in the network:
- staking (Staking Layer);
- interactions (Interop Layer);
- performance (Execution Layer);
- proofs (Proving Layer).
Staking Layer is a Proof-of-Stake based protocol that uses the Polygon (MATIC) token to ensure decentralization of existing chains in the ecosystem. This is achieved through a pool of validators and a built-in staking model. The former receive rewards for blocked assets and additional income from commissions for verifying transactions.
The Interop Layer provides messaging between networks within an ecosystem.
“It abstracts away the complexity of cross-chain transactions and makes Polygon look like a single chain, enabling native Ethereum assets to be shared and seamlessly linked,” the developers explained.
The Interop Layer is based on the LxLy protocol (used by Polygon zkEVM) based on zero-knowledge proof (ZK-Rollups) technology for security.
The Execution Layer allows any network on Polygon to create sequential batches of transactions – blocks. It includes several components that are typical for most blockchains (Bitcoin, Ethereum and others) like consensus, mempool, database, synchronization, etc.
“This protocol layer is quite commercialized, as it is used in a similar format by most networks, but is relatively difficult to implement,” the developers noted.
For this reason, they plan to use existing effective solutions as widely as possible.
Proving Layer is a productive and flexible verification protocol. It confirms all transactions on the network. The level has three components:
- common prover for proof of transactions;
- state machine for their interpretation;
- and optionally a State machine constructor that will define them.
According to the team, this structure provides a number of advantages, including simple and efficient creation, aggregation, and verification of evidence.
The developers promised to share more details about each component of Polygon 2.0 in the near future.
Recall that when presenting the concept of the planned update, they outlined its goal as turning the network into a “value level” for the Internet.
