Earls should stop supporting scams for 30$.

Good post. But please notice that Pharma - BT scam IS NOT from Poland.

XPH-BT Scammers are from Russia!

There is no point in supporting new coins, clever money and whales have fully left new alts. Start investing in older coins and cope with the thought that you wont make 50-100x profits and be happy with 50-100% one at a time.

If you rent a rig and try to rape a new coin you usually can't even jump out since there is no volume or buy walls anymore on smaller exchanges which add these coins.

@earlz, please stop what you are doing. Making reviews for coins will just act like a noobtrap for people who can't do their own research. You are currently supporting new coins which pay you 30$. You have not taken a better look at your review even after the coin had half of LTC's nethash which is impossible for a coin which has: 1) unknown Polish devs 2) mockups as their office pictures 3) PR account can't even use proper english 4) advertised to send illegal drugs to EU countries

So according to your first "A" review, this coin had a clean code and had obviously a legit hashrate.

Literally 99% of the past few month launches have been abandoned, and this was horribly obvious.

I told that there're Rus or Ukr:)

I wonder if bagholders - if they could turn time - would want to scam those motherfuckers...

Maybe a little blackmail to scam them?  


Anyone downloaded it and can confirm??

This coin was a scam, like a fucked up bug he is selling to other dev's. Bug is some fake hashrate what should result in a high popularity because people think many people like it because of the high hash rate. Anyway the hash rate is fake, thats why the pharma dev is selling this ''bug''.

Just drop ur coins and switch back to the reall proven coins, this is just a warning, u can do whatever u want with this information.

For more proofs visit the masterdogecoin topic, same shit

Judging by the telephone number, the developer is actually Russian, this number belongs to Beeline (operator).

I was going to give exchanges a bit more time to react, but I don't want to sit on this longer than needed.

TL;DR; Exploit, blockchain is completely ruined and unsalvageable. Devs used exploit to amplify their hashrate and mine all the blocks

KNOWN COINS AFFECTED: Pharmacoin, Hexxcoin, MasterDOGE
(Note, just because a coin is affected does not mean the developer had any knowledge of this)

Pharma and thus all of it's forks have a LIVE EXPLOIT. Investigation continues as to what source code is responsible,
However. I can point to the side-effects of this exploit:

The PoW hash in Pharma is "distorted" to appear to be more powerful than it actually is.
It appears that the scrypt hash is generated correctly, but then modified seemingly unintentionally.
The end result is that this mangled hash is a higher difficulty than it actually is, thus making the entire
coin network have a higher difficulty than it really does.

A miner MUST take this into account when generating blocks on this network. A legit mining pool's blocks
will still be considered valid. However, a malicious miner can use this advantage and mine blocks that are much weaker,
and thus can basically have their hashrate amplified by a significant amount.

You can prove that a pool knowingly took part in this by taking it's PoW hash of a block it solved, shifting it left by 1 byte
and confirming that the block's PoW hash does not match the difficulty required for the network at that time

You can verify this by using this program: https://github.com/Earlz/hashchecker

Code notes:

The exploit is somewhere in pbkdf2.cpp. Some unintuitive pointer arithmetic is done which appears to malform the resulting PoW hash.

A good comparison is to diff it against the version in Crave. I replaced this file with Crave's version and it compiles fine, but results in the wallet instantly failing because the genesis seed hash is no longer matching.

Output (line breaks added for clarity) when also printing out the genesis hash:

[earlz@earlztest2 src]$ ./pharmad -daemon
hash: 00000102617cecd8aeba57d393e295389b83ff81f223898240282757ad7cdf7e

Aborted (core dumped)

For reference, here the hashes are aligned to see the obvious difference.
true hash:   0x00000102617cecd8aeba57d393e295389b83ff81f223898240282757ad7cdf7e
wallet hash: 0x0000000102617cecd8aeba57d393e295389b83ff81f223898240282757ad7cdf

How to check for this exploit in other coins:

Replace the pbkdf2.cpp file with Crave's version from https://raw.githubusercontent.com/industrialcoinmagic/crave/master/src/pbkdf2.cpp
If the blockchain syncs completely after doing this, then it should be safe.

Conclusion:

Honestly, this is the most elaborate exploit I've ever seen in the altcoin world.
The review for Pharma is of course now an invalidated F as well as for Hexxcoin because of this exploit.
I reviewed these coins and found nothing wrong initially because this exploit is so well hidden.
Measures will be taken in the future to verify PoW hashes, but I must remind everyone that my reviews are not 100% guarantees.
My reviews pick out the obvious problems and the simpler exploits. I spend about 1-2 hours per review.
Figuring out this exploit took more than 10 hours all together and I still can't point to the exact line of code that's the problem.
I will continue to strive to review the code in altcoins, but everyone needs to realize that the bad guys have the upper hand here.

CONCLUSION. IT WAS GREAT FRAUD. Upload your XPH a souvenir stick. AND RACING THE morons With PHARMA by the prosecutor.

Haven't dumped on me yet.  Funny video though,  lol.  Like it.  Hey Joseph, is that what you do with your Goat?  And then give yourself a goat award for it.

Not about being a hero.  Just to stop scammers.  Big difference.  Stealing your money would be heroic though

Nevermind, I met some people with ADHD before and I know that can be a rocky road.
Yes, name all the coins you think are mine please.
That way you can save people and become a hero.
Also if you detect my involvement in any coin warn people in advance, so they can thank you.

Has anyone identified a specific actual problem in the XPH code which would cause exaggerated hash rate reports by pharmad ?

Oh and Stuhlman.  Can we all get goat awards still?  U should give one to Caix.

Yes I lost 3.6 BTC on poolstamp.  But I made 75 BTC on Voot and 21BTC on MEOW.  I've won and lost, but as I stated, I rarely trade in ALTs.  Just gamble some BTC into ALTs now and again.  U on the other hand are not as honest as this.  Look through your history and coins you've been posting in.  Dozens.  Mmmm, gee.  I also have witnessed you posting in certain threads over the last year or so and then magically they disappear.  Mmm, I wonder who can delete posts in threads.  Maybe the newbie account that started the coin perhaps and has the power to regulate the threads?  I am honest, willing to admit when I've lost and won on ALTs.  Some of these have been yours, even though you won't admit it. That's OK.  Scammers work like this.  I personally have nothing against you.  You have outsmarted us sometimes and that you deserve credit for.  I want others though to be warned so they don't lose money they may need.  I can afford to lose 10k now and again, others cannot.  One recent scam by u:  skullbuzz, xph.  Others to name if people ask me or care to know

I am thinking you already got Goated yesterday. Why not post on your other thread. Not my fault your coin hit a wall of shit, try using a good basecode. One of the devs on Caix confided in you that I am a scammer? good I am glad you followed his advice and saved your soul. Someone confided in me that you talk more shit than you can swallow. Here is something that will make your day, Do not buy or trade any coin that J. Stuhlman is involved in, the price will go down yaaaay Does this statement meet your approval?

Edit:  "I did not buy this coin, I don't lose money on ALTs, and I rarely trade." you make a statement like this and your post history shows you invested in lots of shitcoins some are very recent, why pretend you do not lose when it's obvious you are being taken for a ride on weekly basis. I mean honestly I trade coins and lose on some on regular basis, why are you in denial?

I will not go through all your history but this quote shows exactly what you are:

And Stuhlman, can we all get goat awards?
