The NAS token, which is an Ethereum based ERC20, serves as a currency on the Nebulas ecosystem. In order to attract top developers to create more value in Nebulas, the NAS token is used an incentive.
The Nebulas itself is a blockchain operating system and search engine based on value. It’s designed to feature Nebulas Rank (NR) that measures value by considering liquidity and propagation of the address, Nebulas Force (NF). The NF supports smart contract and core protocol upgrading as well as the Developer Incentive Protocol (DIP) that is designed to improve the blockchain ecosystem.
