I only have a very basic understanding of iota transactions, but after reading
I have the following question: Doesn't reattaching transactions allow double-spend transactions?
How does the tangle or nodes processing transactions determine the difference between an initial transaction that transfers value and a transaction that was just reattached?
Let's assume I have account
10 Mi balance, and I send
1 Mi to
B: How is reattaching this transaction preventing other nodes to believe I am not sending the transaction again?
