Witness Chain has unveiled plans to create the DePIN Coordination Layer (DCL) in collaboration with the Polygon CDK (Chain Development Kit). The DCL is designed to serve various functions. Initially, it enables the development of composite DePIN DApps, combining DeFi and DePIN to offer innovative software solutions.

Moreover, it empowers DePIN nodes to be programmable, facilitating the trading of futures market resources such as computation, electricity, bandwidth, and storage. Additionally, it implements rollups and dual staking for DePIN.

Furthermore, the DCL promotes on-chain asset listing and consensus on real-world scenarios involving DePIN nodes. It also streamlines the bridging process and supports optimistic rollups by consolidating Rollup Watchtower proofs on AggLayer.

The qualities of the Polygon CDK make it well-suited for the DePIN Coordination Layer. Firstly, it ensures Ethereum Security by leveraging Ethereum's robust security measures and settling proofs on the Ethereum network. Secondly, it enables interoperability, allowing CDK chains to exchange data and interact seamlessly through AggLayer. This facilitates the utilization of proofs from the Witness Chain's DCL layer within other chains. Additionally, CDK offers gas customization services.

The Polygon Chain Development Kit (CDK) is an open-source, modular software toolkit that developers can utilize to construct new L2 chains on Ethereum, featuring zero-knowledge proof (zkEVM) with optional validium.
