CPChain, which stands for Cyber Physical Chain, is developing a decentralized IoT infrastructure. Their goal is to build a blockchain-based data platform for IoT systems that will use distributed storage, encryption, and decentralized exchanges of value to better connect devices. CPChain will enable IoT-connected devices to connect with each other, and will serve as a decentralized marketplace for IoT related data. Their platform will have a parallel distributed architecture, a hybrid two-layer consensus mechanism, and a side chain consensus protocol. Their network is currently powered by the Ethereum-based CPC token.

Oyster is a blockchain-based platform that is designed to provide both a decentralized file storage solution and an alternative ad revenue system for content distribution. Their network is powered by PRL tokens. Oyster hopes to allow users to store data anonymously and securely on the IOTA Tangle. It uses IOTA’s infrastructure for hosting data stored on the Oyster platform. A data file is broken into chunks, and each of these chunks is encrypted. These encrypted chunks exist as transactions on the IOTA Tangle and are retained on the Tangle.
Oyster's alternative ad revenue platform will use this decentralized data storage network to incentivize users to contribute their devices' computing resources.
