According to a medium post(
https://ethereumworldnews.com/neo-and-gas-on-a-tear-with-double-digit-gains/) last week the Neo Name Service mainnet launch date has been set for October 9th. This service will allow domain mining and rewards for those entering the .neo domain name ecosystem. Neos fuel, GAS, is surging right now as it will be used to bid for domains using the NNS. Reddit commenters have speculated a number of reasons including an Upbit lising for GAS and ONT, but the pump is likely to be linked to the upcoming NNS and associated GAS airdrops.
