# Would an upgrade path change how you choose a starting evidence package?

I’m the creator of SpinStream. This is the approach behind my project.

Mark the work now and carry an upgrade credit with the record. The Marker Certificate includes an $8 Seal Credit toward either Standard Seal or Blockchain Seal.

That makes the Standard upgrade payment $27 or the Blockchain upgrade payment $67, after applying the credit. Each upgrade payment is additional to the original $4.99 Marker purchase.

Would an upgrade path change how you choose a starting evidence package?
