I'm new to Blockchain and would like to understand few concepts in a detail. After reading about basics of Blockchain, one thing is unclear to me about tx. manipulation.
For instance, A has some (i.e: $10) money and A is sending half($5) of it to B. but C manipulate that transaction before going to Blockchain and set $10 instead.
Now, A wanted to send only $5, but some how A's account will get empty since miner will check A has enough balance or not.
How Blokchain resolves this type of scenario?
