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.

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.
