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.

Harmony is developing an open consensus blockchain platform. Harmony's sharding-based consensus mechanism is designed to scale as the number of nodes increases in the network. Harmony aims to tackle issues related to scalability by optimizing across multiple layers in a way that will enable parallel transaction processing with reduced latency. Harmony is currently powered by the ONE token, which is built on the Binance blockchain.

ProximaX is developing a NEM-based platform with several on-chain and off-chain protocols. At its core, ProximaX is based on the NEM blockchain, and is designed to be an all-in-one platform for developing DApps. The platform has several parallel layers that are intended to provide decentralized storage, messaging, streaming, and content delivery services. The network is powered by the NEM-based XPX token. ProximaX intends on using a hybrid consensus mechanism for validating value transfers on these layers. Consensus will be driven with a combination of Proof-of-Importance (PoI), Proof-of-Storage (PoSt), and Proof-of-Bandwidth (PoB).
