Presearch will launch a node explorer in Q1, 2021, that will show more global stats about the overall network (how many nodes, performance, etc.).

We've been focused on getting the core search capabilities ready and both the search experience for the Presearch Engine and the Nodes Beta and testnet out and ramping up users in for beta testing prior to the holidays. We're prioritizing bug fixes right now that come in from beta testers, but we'll have the rewards system for nodes and the stats API rolled out in January. The node explorer will likely come sometime after the public launch of the Presearch Engine (with Presearch running the nodes) but before the node operator nodes fully transition from the Testnet to production.
