Nethereum is an open source .NET integration library for Ethereum. It is designed to help developers easily integrate the Ethereum blockchain into their .NET applications. It consists of modular libraries for features that are covered are writing smart contracts, cryptographic wallets, DApps, and managing blockchain data.

CanonChain is developing an underlying blockchain protocol based on Fog networking and a Proof-of-Participation (PoP) consensus mechanism. Their network is designed to provide incentives for contributing computing resources on fragmented networks, and is powered by the Ethereum-based CZR token, known as Xuanchi.

IOST (Internet of Services Token) is a blockchain platform that is focused on improving transaction speed and scalability. IOST has a unique Proof of Believability consensus mechanism that is based on past contributions and behavior.
The company claims that their platform will increase security and efficiency compared to other platforms. IOST uses a sharding technique that splits the network into smaller ones and randomly assigns tasks for the nodes on the network.
