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.

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.

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.
