Nectar was originally launched in 2017 by the Bitfinex spin-off exchange, Ethfinex — a team based out of London, UK — with the purpose of rewarding market makers for the value they create whilst simultaneously serving as the primary voting mechanism, allowing traders to govern the exchange and decide, among other things, which tokens they wish to see listed next.
