NEM (XEM) is a decentralized blockchain platform that aims to provide fast, secure, and scalable transactions for enterprise-level applications. It was created in 2015 by the NEM.io Foundation and operates on a consensus algorithm called Proof of Importance (PoI) which takes into account a user’s overall contributions to the network rather than just the amount of tokens held. NEM also has a unique multisignature feature which allows for secure and efficient transaction approvals from multiple parties.
NEM also has its own native cryptocurrency, XEM, which is used to pay for transactions and to vote for supernodes, who are responsible for maintaining the network. NEM has been gaining popularity among enterprise-level projects due to its high-performance and security attributes, positioning itself as a next-generation blockchain platform for enterprise-level applications.
