Primecoin is a rather interesting digital currency. It was developed by Sunny King, one of the same developers that created PPCoin and invented Proof-of-stake. Primecoin does not follow the same rules as the other currencies, and has a built in mathematical benefit. Due to the way it is mined, Primecoin actually discovers previously unknown prime numbers.

Primecoin does not follow the same rules as the other currencies, and has a built in mathematical benefit. Due to the way it is mined, Primecoin actually discovers previously unknown prime numbers. The innovative prime proof-of-work in Primecoin not only provides security and minting to the network, but also generates a special form of prime number chains of interest to mathematical research. Thus primecoin network is energy-multiuse, compared to bitcoin network. Primecoin is designed to sustain a prosperous mining market and high level of security, while maintaining good scarcity property like gold. Primecoin also processes payment transactions 10x faster than bitcoin network. All in all, Primecoin presents itself as an extremely interesting experiment; for the first time, we have a currency whose mining algorithm has a secondary value, and at the same time Primecoin, unlike so many other coins before it, actually makes serious attempts to improve on Bitcoin in unrelated aspects. Not taking into account Bitcoin’s massive headstart, Primecoin may well be the first alternative coin to actually be better than Bitcoin, giving the currency the potential for a bright future ahead.
Lunyr (pronounced Lunar), however, is one of the most unique implementations of blockchain yet, aiming to be a decentralized, and peer-to-peer knowledge database, aka the “Blockchain-based Wikipedia”. It strives to be the most innovative and comprehensive source of knowledge in domains like crypto projects, technology, finance, law, investment, and more, on the web. The cofounders of Lunyr are Arnold Pham, Andrew Tran, and Christopher Smith. The Lunyr ICO ended on 26th April 2017, with around USD 0.3 million in capital being generated. The open beta was then launched on 30th January 2018. It is based on the Ethereum network. The reward system which enables writers to earn rewards for authoring articles was also launched at the same time, allowing writers to earn LUN coins in exchange for quality pieces. Initially, Lunyr will mostly focus on the world of cryptocurrencies and related domains, with emphasis on up and coming projects. After an active and dedicated community of readers and writers is developed, Lunyr will branch into other areas such as science and technology, investment, finance, etc. Lunyr is unique in its vision, and usage of the blockchain technology in order to provide a comprehensive, decentralised, crowdsource, and peer-reviewed vault of knowledge, open and free to everyone. Lunyr aims to not only be a knowledge encyclopedia for the web, but also intends to enhance the blockchain technology by giving DApps (Decentralised Applications) the ability to tap into the knowledge base and access real-time data. This innovative feature can be used in applications ranging from Virtual Reality to Artificial Intelligence. The decentralised and peer-to-peer nature of Lunyr allows all content on the knowledge-base to be free from manipulation, and censorship. Since all submissions are peer-reviewed by the community, the chances of incorrect or dubious data making its way onto the encyclopedia are very low.
