We plan to integrate the data availability layer with Polygon Labs’ chain development kit, an open source codebase used for layer 2 chain development.
This integration introduces a specialized data availability solution for Layer 2 projects using Polygon CDK, such as OKX, Immutable, Astar, IDEX, Palm Network, and more. This aims to potentially reduce gas fees for these projects, which are part of Polygon 2.0, which envisions an ecosystem of layer 2 chains that can interact with each other.
The layer 2 network developed in Polygon’s CDK uses zero-knowledge rollup technology. They aggregate off-chain transactions and finalize them into bundles on the mainnet. However, these chains require data availability checks. This means that all network members can securely retrieve and verify data stored off-chain.
The problem arises because Ethereum, the platform these chains often rely on, lacks a dedicated execution environment for the 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 can come into play.
Celestia’s strategy includes its own data availability solution that can provide storage bandwidth to multiple Layer 2 networks simultaneously. This solution facilitates DA verification without placing undue burden on the network by allowing light nodes to run on the network.
“Celestia’s native solution, combined with the interoperability and unified liquidity provided by Polygon 2.0, will make creating new L2 chains as simple and cheap as deploying smart contracts,” said Sandeep Nailwal, co-founder of Polygon. “He said.
What is Celestia?
Unlike monolithic layer 1 blockchains like Ethereum and Solana, Celestia aims to be a modular network. Its architecture is designed to allow nodes to reach consensus on transactions in parallel across chains executing off-chain.
In October 2022, Celestia Labs raised $55 million at a valuation of over $1 billion in a funding round led by Bain Capital and Polychain.
