Yeah you can create your own site and show all the fake address transactions there which is happening in the market especially those who are trying to scam people. Those who said they receive 4ETH after sending 2ETH are totally scam and they are showing some transactions on that, well its fake of course. You better to be good on IT on creating your own site but if its a school project then it must not be complicated like this. You can't make transactions like this, its not possible or else create your own address and make transactions between those addresses.
