Hmm just found out that Quarkbar did indeed have a premine.. found 20 days after i posted this.

Do your own due diligence people, this is just from a github search with scam code.. you make your own decisions.

We managed to get rid of 98% of the malicious Quarkbar coins luckily and were able to freeze his trading account at an exchange.

rainbowcoin is no premine scam i mined that from the very first block.u need to stop making false accusations and do some research .u are a complete moron

There are at least two coins of the same name. LGBT isn't the one with hidden premine.

Dygus could you please link to the source of your information?

Also how does changing algorithm now affect the blocks (that may have been) pre-mined? The OP isn't claiming BeeCoin is a scam just pointing out a potential vulnerability. Don't shoot the messenger because you don't like the news they bring.

If you want to help Beecoin make sure the dev sees this tread.

Disclaimer: I own a small amount of of Beecoin (<50K) that I acquired while researching mining.

Thanks

Bee coin isn't scam there is new dev and he's changing algo from POW to X11 POS, you should read befor telling shits.

Beecoin's resurrection plan is on the move for quite some time. Check it out here:

Love QB, glad it was cleared

Same here

I can confirm that Quickbar and Beecoin does NOT have the other markers of the premine hiding (that exists in main.h and main.cpp). So it was probably is nothing.

Though that code fragment still seems incorrect and should be patched even if harmless.

You've done great work on this, btw. Impressive that you found it!

The ValueFromAmountWithFee function in itself is innocuous.
It seems to return the value of transaction in case that the tx fee exceeds the maximum.

To see where it is used to hide premine, I searched for line

Code:

ValueFromAmountWithFee(pindexBest->nMoneySupply)

The results are here

https://github.com/search?q=ValueFromAmountWithFee%28pindexBest-%3EnMoneySupply%29&type=Code&ref=searchresults

The first coin to pull the scam is
SHACoin

followed (knowingly or not) by
Evercoin
RainbowCoin
Asiacoin
xxxcoin

This clears Beecoin and Quarkbar of suspicion.

Just an FYI, the Rainbowcoin on that list is not the same one as the SHA256 one (https://github.com/Rainbowcoin/Rainbowcoin).

There are alot of changes coming with Bee , better hold it for now.
I'm the new Dev working on Bee and will update as needed.

For the moment Bee is in a transition phase to X11 with POS so I believe you can assume we are on the safe side.

yeah it may be nothing.. but just giving you guys a heads up.. might want to patch that code, regardless tho, it's just .. wrong

Quarkbar is patched, but we will have to look into the total amount of coins.

Stay away from all the coins you are not sure of. That is around 99% of that alt-xxxx!
