NNS is an ending in “.neo” decentralized domain name service based on the NEO blockchain. NNS can replace long, irregular strings that are hard for human brains to remember with words and phrases.
For example, you can transfer a token to an NNS domain name instead of a blockchain address. NNS is extensible. Domain names can be mapped to any blockchain identifier or resource such as contract hash, content hash, public key, and so forth. NNS is a purely smart contract services system on NEO platform with its purpose of improving NEO’s usability.
NNS’s management and services are both done via the smart contract, which is completely decentralized, highly secure and credible. NNS has its own token called NNC with a total supply of 1 billion. System income will be redistributed to NNC holders. NNC is the only payment token to buy and sell .neo domains on the domain secondary market. NNC holders will also be airdropped an equal ratio of the new token when we do the name service on Ontology.
