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.

Skycoin began as an ambitious infrastructure project aimed at replacing the Proof-of-Work (PoW) and Proof-of-Stake (PoS) consensus algorithms that dominate current blockchain platforms. It has since evolved into a project focused on creating a decentralized mesh-Internet and a platform for other blockchain-based projects. Skycoin is developing an ecosystem with a variety of goals, including: the elimination of mining rewards, development of energy-efficient custom hardware, advancing security and privacy, and achieving transaction speeds that rival current digital payment systems. The ecosystem consists of the native SKY coin, Skywire (decentralized mesh-Internet), Skyminer (hardware and access point for Skywire), Skyledger (decentralized open blockchain network), and a suite of DApps. The consensus algorithm is called Obelisk. The network's nodes agree based on a Web-of-Trust consensus. The ability to influence transaction verification is distributed over the network creating a web of trust. To eliminate mining completely each node on the network connects to a list of nodes that it sees as trustworthy.

Namecoin is a blockchain-based DNS that allows users to register domain names with a ".bit" domain. Namecoin was the first fork of the Bitcoin protocol and it aims to remove centralized control over domain registration. It was the first cryptocurrency to use Auxiliary Proof of Work (AuxPoW) as a consensus mechanism,
where a child blockchain is dependent on the Proof-of-Work consensus of the parent blockchain. This allows for Namecoin and Bitcoin to be mined simultaneously, and when a new block is created on Bitcoin, it will also be added to the Namecoin blockchain.
Namecoin is a very important project that represents one of the best use cases of blockchain technology in protecting free speech and resisting censorship on the internet. It is powered by the NMC coin. The decentralized DNS provides more security from hackers and government intervention.
