Polygon 2.0 Roadmap includes unified liquidity, restaking, and new chains on demand.

Polygon, a scaling solution for the Ethereum blockchain, aims to bring together liquidity from various networks in its ecosystem as part of a new architecture under its rebranding as Polygon 2.0.

The plan also includes restaking tokens, allowing investors to stake the same tokens on multiple projects simultaneously. Additionally, Polygon plans to enable developers to add new decentralized chains as needed, joining competitors such as Arbitrum, Optimism, and zkSync’s Matter Labs in the pursuit of fostering broader ecosystems of specialized but compatible blockchains.

Under the new tech stack, Polygon will link the different Polygon chains through a shared crypto bridge powered by zero-knowledge (ZK) proofs, one of the hottest blockchain technologies this year. Earlier this year, it was reported that Polygon would prioritize ZK technology in its future project roadmap.

“Unified liquidity is the key to everything in Polygon 2.0,” said Brendan Farmer, the co-founder of Polygon in a press release. “We need to support unlimited scalability, but the entire Polygon 2.0 ecosystem must still feel like using a single chain. The validity of cross-chain transactions is guaranteed by ZK proofs posted to Ethereum, but we want bridging to feel seamless. We can’t make users wait for a chain to generate a proof or settle on Ethereum.”

With the new architecture, a coordination layer will be introduced to confirm cross-chain transactions, while the shared bridge will be powered by ZK proofs.

“With zero knowledge proofs, we can essentially bridge or initiate cross-chain transactions in a safe and instant manner,” Farmer explained in an interview.

“And so what we want is this coordination layer for the shared bridge that allows for an unlimited number of chains, but for those chains to behave in a unified way,” Farmer said. “For a user, it feels like you’re using a single chain.”

Polygon provided a technical description of how it works: “Native Ethereum tokens will be deposited into a single contract on Ethereum, so when a user transacts across Polygon chains, the corresponding assets will be mapped to the tokens deposited on Ethereum. There is no need for wrapped tokens and the associated UX difficulties.” UX stands for user experience.

The proposal also emphasizes restaking, which enables users to repurpose their staked crypto to ensure the security of other applications on a blockchain. Many protocols, such as Eigenlayer, have recently embraced restaking.

Vitalik Buterin, the co-founder of the Ethereum blockchain, has expressed concerns about restaking, fearing that it could create systemic risks for blockchains.

“I think restaking is a really nice answer to that question where there will be validators that stake the token in order to validate chains on Polygon,” Farmer said. “They’ll be able to not only validate one chain, but they’ll be able to restake their tokens to actually serve as decentralized validators.”

The announcement about Polygon’s new architecture and tech stack comes shortly after sharing a proposal to upgrade its Polygon PoS chain to a zkEVM validium. Polygon has also stated that it will release further announcements in the coming weeks regarding its token, $MATIC, and its governance process.

“I think one of the guiding principles behind Polygon 2.0 is that we want to build this foundational piece of the internet, the value layer for the internet,” Farmer said.
