I am beginner and I am still learning fundamentals of block and bitcoin network.
Suppose, I do a transaction on bitcoin network, it is marked as unconfirmed transaction and is stored in mempool of full nodes.
This unconfirmed distributed over network, at some point a minor will create a block which will contain this transaction.
My question is where these unconfirmed transactions are stored before being included in block or hence block chain?
Can they be modified before a minor put them in blockchain?
