Polygon CDK will integrate Celestia’s data availability to lower transaction fees by 100x

Polygon Labs announced that Polygon CDK will add Celestia’s data availability plug-in to lower transaction fees by 100x.

Polygon Chain Development Kit (Polygon CDK) is a blockchain development tool that allow developers to build their own zk-EVM blockchains. Astar and Immutable zkEVM are blockchains that built using Polygon CDK.

Polygon CDK will integrate with Celestia’s data availability. Polygon said that Celestia’s data availability layer can reduce Polygon CDK’s transaction fees for end users by more than 100x because storing compressed data on Celestia is 100x cheaper than on Ethereum.

How Celestia’s data availability works?

A blockchain transaction consists of 4 layers including

Execution layer

It imposes programming language that build on top of a blockchain such as Solidity, Rust, Cairo.

Or it tells what blockchain development tool a particular blockchain builds on such as OP Stack, Cosmos SDK, Polygon CDK.

Consensus layer

It is a mechanism to create new blocks confirm and transactions such as Proof-of-Work and Proof-of-Stake.

Data availability layer

It is data that available for downloading to verify the transactions such as Alice transferred 5 BTC to Bob.

Settlement layer

It adds transaction data into the blockchain. Settlement layers ensures the transaction cannot be rolled back when the transaction is completed.

Celestia is a modular blockchain as opposed to traditional monolithic blockchain.

Celestia blockchain’s nodes can process 4 layers of a blockchain transaction separately. This make Celestia’s nodes be able to process data availability layer of blockchains that use Polygon CDK.

Data availability solution is an easily-pluggable component, it will be available to developers of Polygon CDK in early 2024.
