Recently I am trying to deploy my first blockcert from the scratch. And here is roughly what I have done:
Generated a wallet address (as well as the private key) on the bitcoin testate
Created an issuer file and post it to https://raw.githubusercontent.com/ppfish45/Blockcerts_test/master/test.json
Batched two unsigned certificates with this issuer_id above
Issue the two certificates by cert-issuer
Upload the signed certificates onto the blockcerts.org to see whether it can be verified
The step 0, 1, 2, 3 just went smoothly. However, when verifying the signed certificates on the website, it said “Transaction occurred at time when issuing address was not considered valid”.
I can’t figure out why it happens. Although there is a thread talking about this issue, I have not get any solution from it. My concerting is that - whether the website only accepts those certificates issued by the issuing address which is REGISTERED ON THE WEBSITE?
Or is it caused by some other reasons that I ignored?
I appreciate any of your help. Thanks!!!
