Job McCaleb founded the network Stellar and created the network's native currency in the year 2014.
Stellar Lumen is an intermidiary currency that facilities currency exchange in transactions. This should not come as suprise; because Stellar Lumen project is a fork of the more popular Ripple crpytocurrenc.
This is a huge step not only for Stellar projet but also for the crpytocurrency industry.
I believe in Stellar project as they are adding a lot in blockchain and crypto space.
