# Subscan

## What is a Block Explorer

Blockchain ecosystems typically have a service that indexes the blocks of the chain and presents the information read from the blocks in a readable and searchable manner. This kind of service is called Block Explorer, and the main goal for such tools is to provide observability on what's happening on the chain.

## Subscan

In the Substrate ecosystem, the most advanced Block Explorer is called Subscan.

Subscan supports indexing the Humanode network. Use the link below to see the Humanode page on Subscan.
