Summary Completed of outputs

  • Complete work from milestone 1
  • Create public ODV documentation and SDK
  • Build a functioning use-case prototype with a dummy solution on pre-production
  • Create a medium article with evidence showing the above

The rock star development team from Charli3 and Metalamp, under the leadership of George Flevorsky, have just completed a functioning MVP of the “pull based” Charli3 oracle!

What did we build and how will it impact Cardano?

Protocols on Cardano will now be able to use Charli3 to request data on demand (instead of setting an interval to receive the data, otherwise known as a push oracle). The benefit to protocols will be a) lower costs as you only pull data when required, and b) the ability to integrate payment for data delivery at time of user request. The latter benefit comes with increased integration work, but the elimination of the need to regularly “fill up” feeds with tokens/payment.
