DragonGlass Transaction Links in Proof Certificate not working
I can see transaction links (via dragonglass) on the proof certificate do not show any results on dragonglass. Am i missing something? The transaction id is however searchable on other explorers.

submitProof command not working sometimes
tried using both collection level and database level proofs but same thing happen. Also purchased the developer plan but no luck. Here is the service(for a document level proof) & the error:
dbObject.command(
{
submitProof: currentVersion,
collections: ["provenDiamonds"],
filter: newDocument, },
(error, res) => {
if (error) {
console.error(error);
reject("Could not submitproof for version.");
} else {
console.log(res);
resolve("New proof created.", res);
}
}
);
ERROR =>
MongoServerError: UNAVAILABLE: io exception

}
the thing is those documents stored in the database without a proof and the request not get resolved or rejected either. Here I attached the output when I try to get the proof of such documents using getDocumentProof.
{
"collection": "provenDiamonds",
"version": 25,
"documentId": "61de71ac00c5985c343f70e3",
"errmsg": "There is no proof for this version of the document"
}

What blockchain does ProvenDB Use?
What blockchain (bitcoin, ethereum, etc...) does ProvenDB use for posting proofs?
Do you plan to support other or private blockchains in the future?

I submitted a question earlier before I signed up and wondered if you had received it.

Add comment button was not working
Hi, sorry for writing here but the add comment button was not working on my previous post. This is the answer to this post: https://provendb.readme.io/discuss/601dd3a16d2388007def3f93
Yes, you are right, I meant submitProof.
So I created now again two documents in the database "xf1" in the collection "col_uploadedFiles" with the ids:
601e5125cf2db37b71deff4a, 601e5125cf2db37b71deff4b
Then I submit this command:
"{submitProof:45, collections:'col_uploadedFiles', filter: {_id: ObjectId('601e5125cf2db37b71deff4b')}, anchorType: 'ETH_MAINNET'}"
Now just 601e5125cf2db37b71deff4b should be verified by the blockchain.
But when I fo a getProof for 601e5125cf2db37b71deff4a,
I get this response:
"{ \"ok\" : 1, \"proofs\" : [{ \"collection\" : \"col_uploadedFiles\", \"scope\" : \"collection\", \"version\" : 45, \"documentId\" : { \"$oid\" : \"601e5125cf2db37b71deff4a\" }, \"versionProofId\" : \"9b4ce6f3-9955-4076-86ba-4763ef71b07f\", \"status\" : \"Pending\", \"documentHash\" : \"38a6d2b0bf681e43fb0186901a009955854a3af02c680223e3333a48cea9c80b\", \"versionHash\" : \"a3a27437f28b3c47a0c574f45d02dbc84cc1670c74c8ddedb7cca07e67c35d4b\", \"errmsg\" : \"The proof is not yet valid\" }] }"
It would be nice if you can check.
