Hi guys I am still quite new in web3.
So there is this client that require us to store some hash of their documents on Ethereum blockchain for tamper-proof verification purpose.
So that we can also have another verifier that can easily compare the hash of a document to the hash stored on blockchain.
Naturally we setup a prototype on the Ropsten network and it works.
Looking at the transaction, it could cost us 0.1 to 0.2 eth for every document hash.
That made me wonder, what will be the unforeseen problem if we actually use Ropsten network in the production app? So we can mine fake eth to funds the applications for the client? And it is still 100% blockchain based?
I had this fear that data on Ropsten network may be wiped out at any point of time, but I don't see this could be happening from any documentation. I maybe very wrong here but can someone advise me what could go wrong if we build production apps on ropsten?
