Network Attack on XVG / VERGE

[ocminer]

Block 2155850 to 2206272 were mined with super-low-diff for the hackers.. About 35 Millions in a few hours raher than a few weeks.. all alone for one person or group..

What's to say that others didn't also benefit from this? Wasn't the chain open for anyone to mine on those algos? If the difficulty went down with an exploit, it went down for everyone. Right?

only if you had a modified wallet which rejected all transactions. they're not THAT dumb and addittionally spammed the network with lots of micro-transactions which brought normal wallets to become unresponsive. obviously their wallets/daemons are modified and simply don't mine those transactions (you can see that also from the block explorer, all their blocks only contain 1 TX, the TX to themselves).

Hold on here. If i leave my bike without lock, it doesn't give someone the right to steal it. The same applies here.

This is an act of hate, destroying the coin and it is irreversible.

There's a reason those bike locks exist though, especially over here in Amsterdam locks are almost worth as much as the bikes itself.
Welcome to the real world, unfortunately the same rules apply to the Internet ...

Is it an act of hate though ? Could very well just be putting the XVG devs in place after the former hack them being all cocky; we got this, no biggie, we don't need your help ... yeah look how well that worked out

I don't like this.

So, the attack also targeted pools and miners to only allow the hackers to benefit from the low difficulty?

Those hackers planned ahead.

Since nothing really was done about the previous attacks (only a band-aid), the attackers now simply use two algos to fork the chain for their own use and are gaining millions:




Both algos, scrypt and lyra2re can be rented easily for a few bucks at nicehash, they simply send one block scrypt, after that a block lyra2re and so on and all with manipulated timestamps thus lowering diff to lowest possible mining several blocks per minute like this

It seems the attacker is securing his lifetime adult content membership  Hey hey hey...

Well.. check the first post of the thread.. it isn't the first time

Verge should just become an Expanse token. The can code all the same features into smart contracts.

Does any one know why blocks from more than 19 hours before are being added into the blockchain? Wasn't the block drift set to 2 hours? How's this possible?

[cool4y]

I'm wondering when this coin will vanish and go to 0 as Bitconnect. Everybody are aware that is garbage coin used for pnd with lot of vulnerabilities and yet people  are greedy and make money of it. It's just a matter of time before it implodes.

because they "walk back in time" - every of the hacker crafted block has a timestamp previous to the one before.. at some point you are at 19h ... if he would mine some more blocks, you'd be at 24h.. then at 36.. etc. at a certain point in the future.

since the coin compares current time with the latest block's timestamp it thinks "wow, the old block is hella old, I gotta lower difficulty so someone finally gets the chain moving!" and thus lowers the diff.. the more blocks come, the lower the diff.. at a certain point it's at the minimum but still the manipulated blocks fly in so it will never retarget up again until a "recent" block is mined with correct timestamp.

PS: I've explained all that stuff previously already

Wont' happen, too many people in this purely for the greed.

Will devs blacklist the millions of hacked xvg? Will they fix once for all?
Or the xvg owners are just screwed?
I'm seeing big dump is this coin right now.

Ah okay ty, I was just confused because the drift time is meant to prevent this. Am I wrong in that regard?

[HatDen]

Thanks for the description of the bug, yesterday was the last time when the same bug was used, but it was not fixed from the middle of April?

[Hueristic]

Why are people still mining this shitty coin? The codebase is obviously fucked.

This "shitty" coin has bigger mcap than NANO, so either market is delusional or simply your assessment isn't correct.

Do you even understand why Mcap is not an indicator of a coin? If I create a 1 token coin and I buy that coin from myself then I can sell it for anything I want and whatever I sold it for is the Mcap.

Shitcoins like this should die and anyone that buys into them should lose. People that bought this shit didn't do their research or they were to stupid to google either way they deserve what they get. This coin has ZERO new features and is nothing but marketing lies, deal with it and bail while you still can.

Is forking an option ?

[ethereumnews]

Developers are working on a patch, new codebase is in the tunnel

Honestly, I thought about this after the 1st attack. Really, I think they should consider it or converting to another token. It's a logical solution IMO

For whatever reason, Verge is dump-resistant. Happened before, even before the first hack ocminer mentioned. Like one and a hlaf years back, Verge was a pure scrypt-coin and was attacked by big miners, effectively stalling the blockchain. Didn't influence price at all, quite the opposite actually, because liquidity at exchanges was just the coins already being there. This was the reasone they switched to multialg, btw.
Verge pretty much lives up to its heritage here: It was DogecoinDark before. And just like Dogecoin, it moves like a dog on speed in a wheat field.
