+This tool is intended to be a simple, self-hosted explorer for the Bitcoin Vault blockchain, driven by RPC calls to your own bvaultd node. This tool is easy to run but currently lacks features compared to database-backed explorers.
 
 Whatever reasons one might have for running a full node (trustlessness, technical curiosity, supporting the network, etc) it's helpful to appreciate the "fullness" of your node. With this explorer, you can not only explore the blockchain (in the traditional sense of the term "explorer"), but also explore the functional capabilities of your own node.
