i just seen a guy say this on the JPC ANN topic link in my SIG..
Off topic a little.
Bter exchange was hacked for 45million NXT and 112BTC. All hell has broken loose in the past few hours there as the herd mentality took over and a massive SELL ALL COINS AT ANY COST attitude took over the account holders.
Bter even paid the hacker 100BTC more to return the NXT. He failed to return the NXT. More panic selling........
Then cooler heads prevailed with the NXT devs, who agreed to erase the transaction from the blockchain. This was not a rollback, but an erasure of one transaction, requiring a download of the new editted blockchain by all NXT wallets.
made me think hmm i wonder if this could be an advantage ?
like what if they paid the guy and then had the coin team remove the 100BTC anyway even if they got the coins back ?
See how this deleting a transaction or rolling back behavior could be exploited in the future ?
we're treading on thin ice with this mentality i think !
In the future all you would need is a coin team + roll back and a corrupt exchange
and we could see all kinds of worse and worse problems with this new bad precedent we're setting.
a whole new angle of attack and exploitation could be born out of this !
