Writting a document in the blockchain

Hi guys ,
Im still discovering moralis , and would like to ask:
How can I writte/create a document in the blockchain ?
It is little confusing to me what do i need for that:
This is what I think I need:
choose one of the supported blockchain.
get the destination address.
create a “document” and send it. (do I need a “token” for this?)

Now … the document can see something like.
mydoc = {
name: “certificateAB”,
date: “ddmmyyyy”

Can you point some document / concepts to read on moralis?
Thanks again for the support.

what you ask seems similar with a NFT that has an image, you could have a document instead of an image. That is in case that you want that document to be public and visible by everyone.
