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.

T‍he Flow Blockchain aims to be a developer-friendly blockchain for a new generation of DApps and digital assets that power them. Flow Blockchain is based on a unique, multi-role architecture, and is designed to scale without sharding, so that it can accommodate consumer applications with more users. The project was created by Dapper Labs, which previously created Crypto Kitties, one of the most popular blockchain collectible projects. Flow is now being used by NBA Top Shot, an officially licensed NBA platform for player related, blockchan-based collectibles. The founders: Roham Gharegozlou, Dieter Shirley, and Mikhael Naayem launched Flow with the goal of simplifying the DApp development experience.
Flow uses a Proof of Stake consensus mechanism. Flow coins are intended to be used as payment for validation services, data and computation, governance, as well as for collateral for secondary tokens that may be created on the platform in the future.

The Elrond blockchain platform is designed to be a public development infrastructure that will be more secure, efficient, and scalable than other blockchain platforms. The Elrond blockchain is aimed at DApp developers and enterprises. Elrond will have a Prof of Stake consensus mechanism, and will include an Adaptive State Sharding feature that will allow multiple validators to process transactions in parallel.
