In CAP block trust calculated that PoW block means nothing. It was only PoS attack.
And now only one chain.
+51% Netweightattack ? ...

the pow hash go from 8 to 540 ? is not a POW attack ?

This is a common problem with many PoW+PoS coins. PoS has an incredible amount of weight when compared to PoW, as you've pointed out, so if there's no staking by others it is trivial to override a sequence of PoW blocks.

When I was considering running my own exchange, one idea I had was for the exchange wallet (or perhaps a separate hot wallet controlled by the exchange) to automatically stake when a customer's deposit arrived, to help lock it in. It's not perfect, since a 'private staker' with enough weight could still overtake the chain, but it's much better than relying on 20 or 30 PoW blocks as confirmation of a deposit.

Your stakes won't matter once the roll back occurs... I'm still running it just to maintain the network but that's it...  If they fork it... then I'll have a few extra coins.

Appears my wallet and Cryptsy aren't on a single connection possibly.. lost several coins.. never arrived.

I call on the community to start reporting these clowns... look at the post history and if it's obvious that they're posting to do nothing more than build post count, report to moderator...

So, any projected date from the team about a solution to the problem at Cryptopia?   

Also, we could use another exchange.  Coinsmarkets.com is taking coins that seem to need a place pretty easily.

Have someone been in contact with cryptopia? Is someone working on the hard fork?

Not that I've seen so far... I'm sure everyone would like to know what's going on.

Wallet status is OK here.   Looks like Cryptopia needs some emailing.

Hey all - Cryptopia has been contacted. I'm syncing up the blockchain for the checkpoint server - no bootstrap.

As you know this part takes awhile - when there's more to share you'll see it here first.

Options are:
- To roll back the chain past the first attack. We are looking at a loss of multiple days, most client will have issues will cause a lot of stress.  But damage is already done.
- Create a fork, that will credit Cryptopia address the coins that were lost. Assuming they were the one targeted.

To prevent this, we need a checkpoint server or much higher confirmations and difficulty.

I can run a checkpoint server, but I can't foot the bill for a VPS to run it. So I would need the community to help with that, or I can give the key to someone else to run. But if that someone does not understand the security,responsibility and how to safety use it, it could kill the chain.

I'm guessing that Cryptopia isn't going to reopen the market until they're made whole... checkpoint or not...  but that's just my guess.

I take it there has been a decision on either option in Tranz's post above... don't know which one... but I'm guessing a simple fork would be the easier and less code intensive...

And I'm guessing ReydeApio has the checkpoint key?

I'm curious as to how the attack on CAP was actually done. Since it didn't require someone to have 51% , but merely to generate faster blocks, how exactly did the attacker accomplish this?

Are there any other possible theoretical attacks we haven't seen on a POS network?

I'd like to see more the community have more discussions about this in order to minimize potential issues in the the future.

I don't know... apparently this is a first for me... didn't even really know it was happening until someone pointed out the negative balance address.

I'll have to learn a bit more about it.

it was explained above a bit... I was under the same impression about 51%. I believe this was actually a double spend attack
