a premine scam.
the dev want to fool ppl twice with AC v2.
the dev want to fool ppl twice with AC v2.
Scam of epic proportions.. helped along by greedy exchanges that put the coin up very early. It netted a *lot* of people. Was highest volume on mintpal for a week... Hard to know how much was scammed.. maybe as much as $1m.
Anyways, I put up the src on github, with the markers //SCAM : url=https://github.com/micryon/AsiaCoinFix/search?q=SCAM&ref=cmdform
and posted an analysis of the code markers here: https://bitcointalksearch.org/topic/m.6535095
Amazingly this SCAM code fragment has been found on several other coins on github...
Prior to this mess i made a Topic here, warning everyone to not get fooled by the high volume and mintpal adding it and exchanges being irresponsible and addressed some concerns which all came true.

I cross posted this from the ANN thread. Seems me and micryon came to the same conclusion independently. I never got as far as checking other files besides main.h and main.cpp
Ok so here are my findings so far. Please correct me if any of this is wrong. Im on about 24 hours without sleep at this point
Note these:
static const int64 MIN_SUPPLY = 1
static const int64 MIN_STAGE_AMOUNT = 10
(Both in main.h I believe)
Here is the meat
Bypass function 1
Which should say if a transaction is larger than MAX_MONEY return error.
But is modified to say
If transaction is larger than MAX_MONEY * 10 ( = 3.4 Billion) return error
Bypass Function 2
This should state. If BlockValue is larger than GetProofOfWorkReward return false
But is modified to say
If BlockValue is larger than GetProofOfWorkReward And is not block 1 return false
Bypass Function 3
MAX_MINT_PROOF_OF_WORK is just completely removed
There are still a few things im uncertain about. But the database does not lie.

Guys does this say what I think it says?
Line 1606 Main.cpp
Line 1606 Main.cpp
Code:
uint256 prevHash = 0;
if(pindex->pprev)
{
prevHash = pindex->pprev->GetBlockHash();
// printf("==> Got prevHash = %s\n", prevHash.ToString().c_str());
}
if (vtx[0].GetValueOut() > GetProofOfWorkReward(pindex->nHeight, nFees) && pindex->nHeight != MIN_SUPPLY)
return false;

Bum bum bum, another one bites the dust..

Did they restart the blockchain because the source code surfer43 posted on the 1st page of this thread shows the maximum coins was 36 million?
May 03, 2014, 12:58:26 PM
delisted on Cryptsy and Mintpal.
why doesn't the community issue a hardfork and kill the hidden premine. I am sure there are plenty of people who would kick some satoshis to see this happen.

It's still a safe coin to invest the rest of our savings into, though, right?
