NEM (New Economy Movement) is a blockchain platform and cryptocurrency that was launched in March 2015 with the goal of offering an improved experience to developers and users. The main cryptocurrency of the NEM network is called XEM. NEM has a unique architecture that includes a smart contract system and a Proof-of-Importance (PoI) consensus algorithm that evaluates the contribution of network participants not only by the number of coins, but also by their activity. The platform also offers built-in functionality for creating and managing digital assets, as well as integration with other blockchains and traditional systems.
