What is confusing me is whether or not each issuing each digital certificate in this manner costs money.
On one hand, I've read through the high-level Blockcerts documentation and blogs and haven't seen any reference to financial costs to issuing certificates on the bitcoin blockchain.
On the other hand, in the
cert-issuer repo it notes in the "Transaction Structure" of "How Batch Issuing Works", the issuer needs a minimal amount of Bitcoin to create the transaction. At the very least, this is a fixed cost.
Additionally, in the documentation we see:
Ensure you've transfered a small amount of coin to your issuing address. Note that each certificate costs 12750 satoshi
Make sure you have enough BTC in your issuing address. ($0.08 USD)
So, it sounds like each certificate costs about $0.30 to issue? Just want to make sure I understand correctly.
(Please note, I am totally new to blockchain, so apologies if this is a dumb/obvious question).
