The Nervos Network is an open-source public blockchain ecosystem that is designed to secure multiple assets. Unlike other smart contract platforms that require users to pay transaction fees to help secure the underlying networks, the Nervos Network hopes to create an incentive system that will enable multiple assets to be secured regardless of their price volatility. It does this by capturing the total network value through its native coin the Nervos CKByte, which entitles holders to storage rights on the Nervos blockchain. The network uses a PoW consensus mechanism.

ArcBlock is creating a blockchain ecosystem for building decentralized applications. Their goal is to provide consumers with the framework and tools to use decentralized apps as easily as current web-based versions. ArcBlock was founded by Robert Mao and Flavien Charlton, who also created Colored Coins, Open Assets Protocol and Openchain.
ArcBlock's Open Chain Access Protocol gives developers an abstract layer for using underlying blockchains. It has a serverless computing architecture that supports various types of applications. ArcBlock is based on the Blocknet application protocol that executes smart contracts and can access external data sources. Blocknet's design and open chain access protocol provide a layer for accessing multiple blockchains.

Hshare is the token that was released in an ICO for the development of the Hcash (Hyper Cash) project. Hcash will be a dual-chain cryptocurrency that will have a side chain for both blockchain-based and other decentralized networks. Hcash is a community driven platform that is designed to exchange value and data across these platforms. Hcash's dual sidechain consists of a blockchain and a Directed Acyclic Graph (DAG) network. It's designed to facilitate exchanges of value between blockchain-based and non-blockchain decentralized systems with a high degree of privacy and encryption. Hcash's dual networks will offer addresses that are inter-operable with other common cryptocurrencies, allowing users to send and receive various currencies in their Hcash wallet.
Hcash has a hybrid PoW and PoS consensus algorithm that combines verification and governance features of both mechanisms.
