The Avalanche token (AVAX) performs various tasks within Avalanche's Proof of Stake blockchain network. The Avalanche token functions as a rewards and payment system for users. The network is designed to be an open-source platform for launching highly decentralized applications, enterprise deployments, and decentralized financial instruments. The Avalanche ecosystem is meant to be smore scalable and interoperable than other blockchain platforms. Unlike Bitcoin and many other networks, transaction fees are “burnt” in order to increase token scarcity. This process is offset by the release, or “minting,” of new coins.
Avalanche was launched by Ava Labs, whose founder Emin Gün Sirer is a veteran computer scientist that has been very influential in the Blockchain space. Gün Sirer is a computer science professor at Cornell University and has written extensively about scaling blockchain networks.

FLO is a Proof-of-Work blockchain with a metadata layer called floData. It enables users to easily record notes to its blocks, and can be used to create DApps. One of FLO's central features is the Open Index Protocol, which standardizes cryptographic ownership on open networks. The founders of FLO are also working on Alexandria; an open-source standard for users to publish and distribute original content. FLO's source code is based on that of Bitcoin and Litecoin. It is designed to enable fast transactions times.

The Cardano blockchain is a 3rd generation blockchain platform that was designed with a collaborative peer-to-peer review system, It aims to improve upon prior blockchain systems to enable larger and more sustainable uses of the technology.
Cardano was built with a governance model that is based on collaboration. This allows the platform to evolve quickly and adapt to the changing needs of its users. Unlike many other blockchain projects, it also installed a treasury system to fund the ongoing development needs that may arise as it moves forward.
The Cardano blockchain uses a unique proof of stake algorithm called Ouroboros and has a protocol that consists of two layers, a settlement layer and a control layer. The settlement layer is designed to perform accounting functions, while the control layer is tasked with running smart contracts. The platform tries to balance the privacy concerns of users with the requirements of regulators in an effective way.
Cardano uses the Haskell programming language and is fueled by the ADA coin
