ProximaX is developing a NEM-based platform with several on-chain and off-chain protocols. At its core, ProximaX is based on the NEM blockchain, and is designed to be an all-in-one platform for developing DApps. The platform has several parallel layers that are intended to provide decentralized storage, messaging, streaming, and content delivery services. The network is powered by the NEM-based XPX token. ProximaX intends on using a hybrid consensus mechanism for validating value transfers on these layers. Consensus will be driven with a combination of Proof-of-Importance (PoI), Proof-of-Storage (PoSt), and Proof-of-Bandwidth (PoB).

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.

Truffle is one of the leading providers of blockchain development tools. The Truffle platform consists of three tools that are designed to assist developers in creating DApps: Truffle, Ganache and Drizzle. Truffle is a testing framework for DApps using the Etereum Virtual Machine. Ganache allows users to easily create a personalized version of the Ethereum blockchain to run tests and execute commands. Drizzle is a collection of front-end libraries that help developers create user interfaces for DApps.
