+
+Simple, stateless Vivocoin blockchain explorer, via RPC. Built with Node.js, express, bootstrap-v4.
+
+This tool is intended to be a simple, stateless, self-hosted explorer for the Vivocoin blockchain, driven by RPC calls to your own smartcashd node. This tool is easy to run but lacks features compared to full-fledged (stateful) explorers.
+
+I built this tool because I wanted to use it myself. Whatever reasons one might have for running a full node (trustlessness, technical curiosity, etc) it's helpful to appreciate the "fullness" of a node.
+
+# Features
+
+* List of recent blocks
+* Browse blocks by height, in ascending or descending order
+* View block details
+* View transaction details, with navigation backward via spent outputs
+* View raw JSON output used to generate most pages
+* Mempool/unconfirmed transaction counts by fee (sat/B)
