NEM is written in Java; built on an entirely new codebase separate and apart from Bitcoin’s open-source code. There are a few other intriguing differences from Bitcoin as well. In NEM, you harvest rather than mine. It’s essentially the same as mining in Bitcoin, only that multiple people profit – albeit in much smaller quantities – from a generated block.
NEM introduced the proof-of-importance algorithm to the digital ledger. A user’s wealth and number of transactions are used to timestamp transactions.
NEM has seen rapid growth in its valuation since the beginning of 2017 as the altcoin is currently being embraced in Japan.
