Even no disbalance in PoS.
He simply alter source and use PoW so it's only illusion.
This coins unspendable.
Where hi get 20 coins from?
Check code.
==================
main.h
27 static const int64_t STATIC_REWARD = 20 * COIN;
==================
But as nodes have right client they never accept that.
Actually it's known attack but he need 51% of all network for success.
Unreal.
Second thing orphans. I think that a lot of orphans because another new coin use same ports. 7117,7118
I post about that, see post #664
Block timeshift can be corrected too. It's not a big deal.
I hope developers will fix that soon. In my opinion even not needs to do hardfork.
About exchanges. I think no needs to disable deposits and withdrawals because market will go down soon.
Nobody need coin that can't buy or sale.
Tell me if I'm wrong.
you dont need 51% to do an attack on pos.
deposits and withdraws are most likely suspended due to the fork as a safety percaution, no harm done in that.
@Perp Thank you for your explanation. Why would those coins be unspendable (are you 100% sure that they would be rejected by a majority of nodes)? If so, what was the perpetrator's purpose in attempting that and how were those 20 reward screenshots taken from the block explorer, if those transactions were indeed true?
Also, have you seen this type of attack on other PoS coins, other similar attacks on PoW coins? There have been so many attacks this past week on various coins like Verge and others like Stipend which have also have to suspend exchange trading while updating their codebase. I read a post somewhere that these types of hacks are just getting started for 2018 as there is so much bad code out there from too many clones with outdated, vulnerable code.
