Nebulas is an innovative project that aims to be the first blockchain search engine. It has been called the “Google for Blockchains." They want to build a self-evolving blockchain system that is based on incentives and will also provide a development infrastructure. The company developed two concepts to achieve their goal: Rank and Force. Similar to Google's PageRank, Nebulas Rank will be a measure of overall value for blockchains. While Nebulas Force, will be a solution that will support smart contracts, and will be able to adapt to market demands. This will prevent forking from occurring because new technologies can be incorporated and bugs can be fixed without changing the underlying code. The development system will provide all of the essential tools needed to create distributed applications. One of the key components of the platform is the incentive structure that has a Developer Incentive Protocol (DIP) and a Proof of Devotion (PoD) protocol that will reward users with Nebulas tokens to create quality applications. Nebulas was created by Hitters Xu, who is also the founder of NEO, and is an important figure in the Chinese blockchain community.

Cardstack is a blockchain technology company that is developing an open-source framework and consensus protocol to make blockchains more usable and scalable. Their goal is to create a decentralized modular smart contract ecosystem. The Cardstack network is powered by the Ethereum-based CARD token.

NEO, formerly known as AntShares, is one of the leading smart contract enabled blockchain platforms that allows for the development of digital assets. Similar to Ethereum, NEO uses two different tokens: NEO and GAS, each of which have a specific purpose on the network. NEO tokens give holders a share in the ownership of the NEO blockchain, and when they are held in a compatible wallet, they are rewarded with GAS tokens. NEO has a Delegated Byzantine Fault Tolerance (dBFT) consensus algorithm that has uses some features of PoS, and is designed to be more scalable than other consensus mechanisms.
