BitNew Chain is building a development platform for commercial DApps. BitNew Chain aims to make it easier to develop large scale DApps that can be used with hardware. It will be based on a two-tier decentralized blockchain network with standard physical masternodes, resource segregation, a decentralized computing subsystem（BTN-DC）, and decentralized storage subsystem（BTN-FS). Consensus will be achieved through a hybrid mining process that will combine Proof-of-Stake (PoS) with Proof of Masternode. The network is powered by the BTN coin.

ChainLink is developing the LINK Network, which will enable connected smart contracts. LINK will provide smart contracts with a variety of external data and access to APIs. ChainLink's goal is to solve the connectivity problem that plagues smart contract based systems, and discourages mass adoption. Many decentralized applications are unable to connect with important external data sources due to limitations involving their consensus protocols. The LINK network wants to connect their smart contracts with external systems and APIs by using secure middleware.
