Transactions differ, some inputs are the same
because they occured in July, 2013, before the fork point (November, 2013).
That means they belong to the part of chain from 2013 which is the same for both chains.
https://chainz.cryptoid.info/lky/address.dws?L3XnfLo5m3BrZxH5PVxxpg38G8F8X7oDfd.htmHere we can see that coins were received in 2013 and spent completely in 2015, but on a new chain which doesn't include blocks from 2015 - they could be spent again and that happened (with same inputs from July, 2013).
According to some sources, it looks like it was something called a "replay attack".
The transactions I mentioned above are just some of the few tx that has been recreated.
It does not need any interaction from the original owner of the address.
Any transactions on these old wallets that occurred later after that block can be replicated on the new chain.
As long as certain conditions are met, like balances and destination addresses.
The entire integrity of this "revival" Luckycoin is now compromised.
What a mess.
