We needed a grin-node running 24/7 for our own purposes and eventually we setup a series of nodes and connected them together. Project went public and new features such as API access and CORE GRIN_DNS Seeds have been added. To encourage growth of this network we even organized a uptime challenge . This is the brief story behind the https://grinnode.live project, a high-available API and Sync-Service for Grin digital currency.
