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.

Nebulas is an innovative project that aims to be the first blockchain search engine. It has been called the “Google for Blockchains." They want to build a self-evolving blockchain system that is based on incentives and will also provide a development infrastructure. The company developed two concepts to achieve their goal: Rank and Force. Similar to Google's PageRank, Nebulas Rank will be a measure of overall value for blockchains. While Nebulas Force, will be a solution that will support smart contracts, and will be able to adapt to market demands. This will prevent forking from occurring because new technologies can be incorporated and bugs can be fixed without changing the underlying code. The development system will provide all of the essential tools needed to create distributed applications. One of the key components of the platform is the incentive structure that has a Developer Incentive Protocol (DIP) and a Proof of Devotion (PoD) protocol that will reward users with Nebulas tokens to create quality applications. Nebulas was created by Hitters Xu, who is also the founder of NEO, and is an important figure in the Chinese blockchain community.

Alqo is developing an ecosystem of decentralized products and services that will be powered by the Alqo coin (XLQ). Their blockchain-based ecosystem enables instant and anonymous transactions. The XLQ coin is designed to be a multipurpose coin that will be used by all projects in the "Alqo Planetary System." Alqo is currently building Bitfineon (cryptocurrency exchange) and Payinx (payment solution for merchants). They plan on adding more projects (planets) to their ecosystem later. The Alqo network uses a modified Proof-of-Stake (PoS) consensus mechanism and an improved version of Zerocoin for encryption. The Alqo DAO (Decentralized Autonomous Organization) uses a Carbon Voting system to resolve governance issues.
