NEM stands for New Economy Movement and powers the Smart Asset System. It’s written in Java and was launched in 2015 – the platform’s currency is called XEM. XEM are harvested through Pol – once you own 10,000 XEM and deposit them in the official NEM Nano wallet they begin ‘harvesting’ and therefore grow in number through interest. Smart Assets allow unique data to be created representing any asset meaning that these assets can be traded using XEM. Multiple ledgers can also exist on one blockchain. CoinDesk also provides a suite of institutional-grade price indexes. Find out more about them here.
