Celestia to integrate data availability layer with Polygon CDK
Celestia will integrate its data availability layer with Polygon Labs’ chain development kit, an open-source codebase used for developing Layer 2 chains.This integration introduces a specialized data availability solution to Layer 2 projects using Polygon CDK, such as OKX, Immutable, Astar, IDEX, Palm Network and others. It aims to potentially reduce gas fees for these projects, which are part of Polygon 2.0, which purports to be an ecosystem of Layer 2 chains capable of interacting with one another.
Layer 2 networks developed on Polygon’s CDK employ zero-knowledge rollup technology. They aggregate transactions off-chain and finalize them in bundles on the mainnet. However, these chains necessitate verifying data availability, which means ensuring every network member can securely retrieve and confirm off-chain stored data. A challenge arises as Ethereum, the platform these chains often rely on, lacks a dedicated execution environment for its DA layer. As a result, Ethereum nodes must process and store data on-chain indefinitely, contributing to increased fees for Layer 2 solutions. This is where data availability solutions may come in.
