NEM

NEM is a peer-to-peer cryptocurrency and blockchain platform launched on 2015. NEM was started by a Bitcoin Talk forum user called UtopianFuture who was inspired by Nxt. The initial plan for NEM was to create a fork of NXT, but this was eventually dismissed in favor of a completely new codebase NEM has a stated goal of a wide distribution model and has introduced new features to blockchain technology such as its proof-of-importance (POI) algorithm, multisignature accounts, encrypted messaging, and an Eigentrust++ reputation system.
NEM's design architecture consists of two components. One is the node or NEM Infrastructure Server (NIS). The second is the client used for interacting with the nodes. The current supported cryptocurrency wallet is the NanoWallet. The NanoWallet is a full cryptocurrency wallet built with HTML and Javascript. As such, it is able to run on any platform with a web browser. NanoWallet communicates with any NIS in order to broadcast transactions to the rest of the network as well as receive information about network events.
The NEM blockchain software is used in a commercial blockchain called Mijin, which is being tested by financial institutions and private companies in Japan and internationally.
