The engineering team at Polygon Labs has proposed an upgrade to its flagship Polygon Proof-of-Stake (PoS) sidechain to “zkEVM Validium,” a Layer 2 network secured by Ethereum.

According to the proposal, the upgrade aims to align the current Polygon PoS chain with the vision for Polygon 2.0, a future version of Polygon that leverages a specific type of zero-knowledge scaling technology called validium.

The proposal, titled “Polygon 2.0,” states its intention to utilize Polygon’s in-house zkEVM to enhance the sidechain’s security and performance while preserving its low fees. This would be separate from the team’s existing zkEVM, which was rolled out in March 2023.

Polygon Labs upgrade

Polygon Labs indicated that it envisions both the upgraded Polygon PoS and the existing zkEVM coexisting within the Polygon ecosystem. If approved, the upgrade could be implemented on the mainnet by the end of 2024.

If accepted by the community, the upgrade will mark the first time that an existing chain has added ZK proofs and transitioned to become an L2. Polygon is currently one of the most widely used blockchains in the crypto sector in terms of daily transactions and holds over $2 billion in on-chain assets.
