Nebulas combines a value-based blockchain and a search engine. Its token called NAS is Ethereum-based and serves as a currency in the network. Marketed as ‘next generation blockchain,’ Nebulas uses consensus systems, oriented to the future innovations. The main structure of the network is presented by three elements – Nebulas Rank (NR), Nebulas Force (NF) and Nebulas Incentive (NI). It is value-based, meaning that a ranking system measures value for every unit in the blockchain; it is self-evolving which enables it to develop quickly and efficiently, and it has a reward system that gives back to its devoted developers and users. Nebulas is a search engine as well, and it works just like Google, but for blockchains – users can get information on more than 2000 decentralized blockchains that are currently in the market. NR rankings are used to determine results in the searches, giving users information on applications and tools that are the most relevant to their needs in the moment.
