The Interplanetary File System (IPFS) is a decentralized network protocol for sharing hypermedia in a distributed file system. IPFS can be used to link blockchain transactions This effectively timestamps and secures the content, without having to put the data on the chain itself. Filecoin, an IPFS-based decentralized storage cloud, is closely related with the IPFS protocol, and provides the incentive system.

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.
