Challenges we ran into

  • Loading the Hedera guardian... I was stuck at 106/143 forever Creating the schema
  • Not sure what is previewnet
  • "Hedera" autocorrects to "Header" on my computer for some reason

Accomplishments that we're proud of

  • Looking at the Verra and Gold Standard documents, I think the methodology has a lot of potential
  • Drafting schema definitions for ZEV credits, transactions, participant identities, etc.
  • Defining policies for issuing, transferring, and redeeming ZEV credits.
  • Acronoyms like VBB

What we learned

  • The Nabla symbol (∇) and Greek letter delta (Δ) are different
  • Applying the idea to an example use case ( Like Tesla or Volkswagen) was very helpful
