Nexus (NXS) is an open source blockchain and peer-to-peer network. The project aims to 'develop technology for communities, enterprise, and connectivity'. Operating since Sep 2014, the project has undergone a series of improvements. The Tritium protocol is running in testnet mode (As of 1 Mar 2019) and will replace the legacy code. Some of the features and improvements include Network Overlays, IP Multicast Locking Groups, Higher Security Standard, and Contracts. As of 1 Mar 2019, Nexus comprises 3 Embassies in the US, UK, and Australia. Each of the Nexus Embassies is a non-profit entity created for technological/business development, along with education. The nonprofit entities have no owners, are represented by a volunteer board of directors, and are operated by teams of creatives and delegates.
