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.

Filament develops hardware and software solutions that allow machines and devices that are connected to the Internet-of-Things to securely interact with a blockchain. Their products leverage the decentralized transaction capabilities of blockchains to better connect these devices and allow them to transact in new ways. Filament offers both external hardware as well as software for embedded devices connected to the IoT.
