Gas would be your least concern if you'd find all the blocks and the setup for such an exploit seems to be very simple.
Keep bumping this.

Yeah this would imply 2 things...
1. People are actually sending transactions to this contract to answer the riddle
2. The contract has a bunch of gas

If someone could post what he said, we can debunk this very quickly.

Ethereum's POC is not turing complete as promised. It is non turing complete. The following class of algorithms catastrophically exploits their mining:
probabilistic polynomial run time algorithms
You may know a common example of these algorithms as prime factorization using random inputs to determine the prime factorization of a number, although there are other examples. The reason this works is because the uploader may know which random number solves the prime factorization. You may read about these algorithms here:

An example of an exploiting contract is this:
Prime factor a number X by guessing and checking randomly through numbers less than X

This works. All you do is multiply prime numbers together to get a larger number, then ask the network to randomly factor the larger number. You already have the answer. Ethereum is worth NOTHING.

Think about it the whole network has to solve a huge cryptgraphic riddle that you already have the answer to. They're saying " oh ya but you would have to solve the huge riddle first!" That's complete BS. All you have to do is multiply a bunch of random small primes together, for example:
7*3 = 21
then host the contract: randomly factor the number 21 into primes. You have the answer already and you post your proof:
"hey i randomly guessed the numbers 3*7 = 21 first and here's my proof while the other miners do this
21/2 = ?
21/4 = ?
21/6= ?
21/3 = 7 oh okay i solved in 4 easy steps but the author solved in 1 step only.
Now try for this number 777777777777777777.
The price is 0 its a 100% catastrophic and unpatchable exploit.
7*3 = 21

again solved in only 1 step instead of 1000s or millions of steps.The price is 0 its a 100% catastrophic and unpatchable exploit.

FUD I am the biggest expert in crypto currency. It's not an error in the code it's an error in the mathematics. Ethereum can only run non probabilistic algorithms.

I'm not sure what the original post was, but I think it had to do something with having an unsolvable block via some code?
All contracts run out of what is called "gas". Gas is Ethereum. Once a contract uses all its Ethereum, it fires an exception, and halts the contract.
If someone could post what he said, we can debunk this very quickly.

Looks like a thread to create panic selling. I am not much into mining, so I will wait for an expert to debunk or not your theory to make my mind up. However I doubt that Ethereum, second best code after Bitcoin's one, would be so flawed 
...
...a 3X inverse short of ethereum is worth about $70 billion at the moment
If OP is going to delete the OP, what is the point of this thread?
Mods should just delete it as it is a waste of space.
Unless someone copied it and post here, but still kind of pointless.
That will never work. Waste of time.
it works
That will never work. Waste of time.
OP has a post history. That is all.
"If you are unaware there was a large shift in power at the time Donald Trump was elected from established Nazi politics to a rebellious pro human political structure. The Nazis held subterranean positions that could house over 100,000,000 infantry now vacant. Humans need to get to these entrenched bunkers and make them their new homes. Security is the highest form of luxury. These are the best positions on the planet and the cheapest to defend. Zion fell to human for the first time in 8,000 years. It is huge underground network of caves and magma. "

this is extremely unrealistic but still can you seriously argue you are in better military position sitting on the surface where any moron with nps can hit you than you would be in an underground bunker.
the answer is no
So the first one to do this will find all blocks, should be easy to figure if its happening.
Could be draining like a cup of Drano.
Imagine all those ICO tokens going to exist in a vacuum ....

Well OP was not online today. Wounder if he now collects the coins.
i wish you didn't speak about price in your comments, you just devalued all the things you said because of mixing the price in the discussions about "an exploit in the code".
i am no expert and didn't understand how this is supposed to work but what i am wondering is why nobody (or you-the self claimed security expert) has already exploited this?

By design cryptocurrency code exploits 'devalue' said currency. Whether the OP mentions this or not the result is the same. His reference to monetary value was in response to a FUD claim.
Doesn't runtime cost gas?
So if you're hoping to grind the network to a halt, you'd better be prepared to pay for it.

Not much news or info out there in the wild about this.
But if confirmed then really after all the bad press and hacks with ETH it might just put the final nail in the coffin.

Are you saying this is Shelby?
I wouldn't be surprised LOL
and my math is pretty shitty but he sounds believable.
But to what extent is this a problem.
Like if you can get an edge then how much are we talking about.
It would be interesting if this was used in the wild and we can see it in action and the results.
Not a lot of people are experts in math and algorithm so I will let them address this.

Sounds like Shelby. It should be an interesting week for eforkeum.
Sadly, I'm not at all surprised by this..

Is there any way to find out if its been exploited already?

I think you are a bit disturbed. May the greatest expert in the world highlight his explanation with something taken from Ethereum GitHub repository ?
Maybe you should apply for a job as a shrink. I don't know their github. This is an algorithmic exploit.
