Celestia and Polygon Labs have partnered to integrate Celestia’s data availability layer with Polygon’s Chain Development Kit.

This partnership marks a step in advancing the capabilities of Layer 2 projects like OKX, Immutable, Astar, IDEX, and Palm Network, which are part of Polygon 2.0 – an ecosystem designed for inter-operating Layer 2 chains.

Layer 2 networks, mainly those built using Polygon’s CDK, utilize zero-knowledge rollup technology. This method involves aggregating transactions off-chain and consolidating them on the mainnet. Data availability verification is key to this process, which ensures all network participants can access and validate data stored off-chain.

However, a challenge presents itself with Ethereum, the underlying platform for many of these chains. Ethereum (ETH) lacks a specific execution environment for its Data Availability (DA) layer, leading to nodes having to process and store data on-chain indefinitely. This results in higher gas fees for Layer 2 solutions.

Celestia’s (TIA) approach brings a data availability solution. It offers storage bandwidth to multiple Layer 2 networks simultaneously, allowing networks to operate light nodes. This method streamlines DA verification without overwhelming the network.

“Combined with interoperability and unified liquidity provided by Polygon 2.0, Celestia’s out-of-the-box solution will make creating new L2 chains as simple and affordable as deploying a smart contract,” Polygon co-founder Sandeep Nailwal said in a release.
