VestChain is developing a smart contract platform that will have a double layer architecture. Their network is currently powered by the Ethereum based VEST token.

The LTO Network is a blockchain platform designed to automate workflows and collaboration between organizations. The company places an emphasis on ensuring regulatory compliance. Their network has a hybrid architecture that combines elements of private and public blockchains.

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.
