Quickstart

1. Anatomy of a Ravencoin Transaction

RvnDB's main job is to:

  1. Transform a raw ravencoin transaction into a structured format
  2. Store it in MongoDB
  3. Make it available for powerful queries

Here's an example of what RvnDB saves into the database (It's a single ravencoin transaction):

2. Try Queries Online

To get familiar with how rvndb queries work, go to the Intro documentation and try out some example queries online:

Try Rvnquery Online

To make sense of what the results mean, see RvnDB 101

3. Try Queries Programmatically

RvnDB can be queried in two ways:

  1. Direct: If you're running your own RvnDB node, you can query your own database instance directly, through mongodb:// url.
  2. Via HTTP: But most people don't need to run their own RvnDB node, especially if you just want to try building things quickly.

Here we will use the HTTP method to connect to a public rvndb node at http://rvndb.ravencoin.online for making requests.

If you're ready, go to the API Dashboard to get the API key and try running the code!
