NEO, previously known as ANT-Shares, is a smart contracts platform from China. It was the first major Ethereum competitor, but was later overtaken by many of its competitors. NEO underwent massive changes to its protocol over the years to remain competitive. Last year, the NEO 3.0 version was released. One interesting aspect to NEO is the separation of native token and gas.
