Howdoo is a revolutionary new messaging and social media platform that offers greater choice and control to users. Designed to encourage a more open and decentralized approach to mass social networking, it’s a platform that gives people full command over their personal data. It’s about incentivizing participation and contribution; allowing this value to flow freely across the network; enabling users to select for themselves the content they want to engage with; and inspiring a fairer, more community-driven form of moderation.
Novacoin is a hybrid Proof of work (POW) / Proof of stake (POS) decentralized peer-to-peer cryptocurrency.The Proof of Work part of Novacoin is based on the Scrypt hashing algorithm. Proof of Stake contributes to the coins energy efficiency, as there is no need for nodes to contribute mining power to part of the money creation process. As of now, Novacoin is set to be capped at 2 billion coins. However Novacoin stated that the cap limit may be lifted if the situation requires it. It looks very much like a variation of Sunny King Peercoin.
