If the Tx ID is not stored on the file that I want it to be verified !
How can I know where was the signed hash stored?

I want to store files on IPFS and when the CID returned, I will sign that hash(cid) and store it on the Blockchain!
But, how can I find that signed hash on the Blockchain.

I mean the blockchain is huge, how can I find the signed hash of the file that I am trying to verify?

If the Tx id is unknown how can I find it?

What if the verifier is an end user?
I am trying to implement this! But, I do not think it is being coded this way.

Is this how people do it on Blockchain?

Yes, but this will be after Storing the file on IPFS

SO, I can not add it to the file

The content will be changed this way

So, what can I do?
