BitTorrent was initially conceived by Bram Cohen, a peer-to-peer protocol for users to transfer files around the world. The BitTorrent Token (BTT), a TRC-10 token is created on top of the TRON blockchain platform as a way to extend the capability of BitTorrent. The token is added to introduce some economics feature on BitTorrent for networking, bandwidth, and storage resources to be shared and tradeed. Some of the other feature that BitTorrent Token (BTT) offers would be BitTorrent Speed. This is whereby BTT tokens can be big in exchange for faster download speed.

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.
