Some fucking dude just got destroyed by sending 232 eth to POWH shadow.

Fucking crypto is always so entertaining. Just tossed 10$ into normal POWH before everyone piles into it

fuck that noise.

meanwhile...

you are so fucking lame, no one's gonna buy, just save your gas. here is a screen shot of this dude getting fucked

Needs more R.I.P's in the comments

HEY HEY HEEEEYYYYYYYYYYYYYY

I just tossed a few out by mr.johnson. Might as well honor those failed tx's with a comment too

Wont the hardfork just fix this?

What hardfork? hahaha

Cool website.

If you guys want to know what happened....

Go to read smart contract, you will see that "reserve" = 115792089237316195418029001632089845036668699831288073378681090919681116870265

that is 0x10000000000000000000000000000000000000000000000000000000000000000
In hex

Basically a number (negative zero) got casted to positive huge number... signed -> unsigned int

So the eth developers are fine with 870eth being stuck in a smart contract forever?

>t. mindlet

Dude more than 1 million eth are stuck because of the parity multisign fiasco, 900 eth aint shit

Original POWH:
var numEthers = getEtherForTokens(amount);

Shadow POWH:
var fees = (uint)(getEtherForTokens(amount)/10);
var numEthers = getEtherForTokens(amount) - fees;

Int overflow from that cast destroyed the contract and left $1M dollars in limbo forever.

This nigga literally changed 1 line of code and fucked the entire contract, way to fuckin go, there's literally no way he can fuck that worse. Even exit scamming would have been better, at least he would have been competent.

>. Even exit scamming would have been better, at least he would have been competent.
this

at least this dude could've pumped my damn shitcoins or something

now the money is all GONE

But think about it. By removing that much eth from the global supply, forever, it makes the value of everyones eth go up! Weeeeeeeeeeeeeee

get in here boys, we're going to the moon-

Dude is this real? It’s impossible to get any out? I sent an ETH fuck

yes, check the contract right now. these values are clearly fucked: etherscan.io/address/0x9f4fd6c336388f2ab7dc7bbe4740ae7b88b880d7#readContract

And if you look at all the transactions, everything fails... bummer for you, but someone lost almost a quarter million dollars.

I'm a POWH dev
JUSTed myself out of 9ETH
Worth it for the LULZ

Which POWH got fucked? Do you meant the green one? Or are we talking about the new ones?

the new, purple one broke... the green one should be fine for now... hopefully there aren't any other errors in these contracts hahaha

Indeed, original self-sustaining green one is a go.

>because of the parity multisign fiasc
what

only the shadow fork got fucked, the original (green one) is working fine

Of course all of them put their money without anyone reading the code before hand. That'S one of the best autistic moves of Veeky Forums

lmao muh ETH is the future.
one bug can fuck up a whole smart contract with this shitty technology. what a shitcoin

on a sidenote, why dont they just open a new fork and grant the public adresses that sent in the same amount of tokens they got in the shadowfork by premining them?

motherboard.vice.com/en_us/article/ywbqmg/parity-multi-signature-wallet-vulnerability-300-million-hard-fork

cause then they don't have the 900 eth to back-up the tokens you idiot

just stick to the clones with unaltered code like that one 0x04129cff7d79a652256c73b1407f34828e79a4de

THey cant do that unless they pay 900 eth to everyone. Powhcoin doesnt really exist, it just the eth stuck in a smart contract.

...

I really hope nobody lost more than 10% of his portfolio ;_;

Ok, that made me laugh lol.

Of course one line of code can fuck up the entire code that is the fucking point of a code you brainlet

WHAT THE FUCK ARE YOU TALKING ABOUT?

I put in 7 eth and withdrew

I then did it again 2 hours later, what the fuck, how did he fuck shit up? Eth is going in and out of the contract every damn second.

The original one is still working fine, just the "shadowfork" version got fucked, because these cunts were too greedy

> 1+1=3 broke math
> damn math is complete garbage, it can't even handle 1+1=3

did they literally forget to dot an "it" or what?

How could this happen. I saw the earlier technical explantion,

but I am wondering if they just didn't paste the code right or something? The first one worked... so shouldn't the second one?

They modified the code with the intention to make even more eth with dividends..

what do you guys think? will we see that money again?

i know but that seems pretty fool-proof. How did that end up fucking 232 eth guy

from the shadowfork page:
"To put it in Laymans terms, the eth is all stuck in the contract because the robot that was giving it out thinks its going to take infintie gas to divvy out negative dividends caused by a programming error on a single line of division."

because every participant "trusted" the scheme contract dev lol ... and no one checked the code before throwing eth in .. anyway most of the participants wouldn't have spotted the bug

Sucks but probably better now than later on instead of having a bigger clusterfuck.

I dont know solidity and my coding is a bit rusty but in the line

var fees = (uint)(getEtherForTokens(amount)/10);

he casts (getEtherForTokens(amount)/10) to int, uint is unsigned int, and can only store positive numbers including 0, some weird transfer fees resulted in a negative or very small number that when casted to unsigned int caused a overflow error, crashing and causing the contract to self destruct, hence all 800ETH +are lost forever

...

look at the upcoming shit contract they are beta testing on ropsten without verified code lol then for sure they modified the shit out of it as well

MY SIDES.PNG

i understood that reference my ami/g/o

Are shares considered tokens?

pretty confused since I tried using the CASHOUT func to get into shadow, got my dividends but I'm still holding some coins.

You're welcome

That a cast can crash a smart contract is so poorly designed... In fact that they can have exceptions at all...

GARBAGE SHILLS PUMPING THIS SHITCOIN, YOUVE BEEN WARNED

Uuuhhhhhhrrrrreeeeerrrrmmmmm what

You are retarded. This wasn’t a clone and was a memorial thread to the one that broke cause of shitty code
