new amd kernel: speed bump around +100kh/s https://github.com/djm34/sgminer-msvc2015 (free of charge however donation are welcomed here: 1NENYmxwZGHsKFmyjTc5WferTn5VTFb7Ze (btc)
or here aChWVb8CpgajadpLmiwDZvZaKizQgHxfh5 (zcoin)

worksize = 32 (or lower) at least on the 290x

my 290x runs around 450kh/s with worksize = 32 and intensity of 18 (instead of 330kh with old kernel)

(for more recent card, may-be it is possible to use bigger worksize depeding of how much shared memory there is... have only a 290x so it is up to the user to try)

We have pushed the fixes for the Zerocoin bug into Github. Windows binary is already up and the rest will be up shortly:
https://github.com/zcoinofficial/zcoin/releases

Please update your wallets and nodes as soon as you can.

Bittrex trading will re-open at noon PST giving everyone some time to react. Special thanks to Bittrex for being very professional and understanding. Nova Exchange is already updating and should be up immediately once they're done. BTC38 has been informed but trading is still open there.

Also shoutout to Suprnova and MPH for also working closely with us and updating in a very timely manner.

We will post a more detailed post mortem as soon as we can on the events that has happened and what we will do moving forward. We thank those who supported us during this difficult time.

For the latest updates you can always join us on Slack (http://invite.zcoin.io:3000) or Twitter (@zcoinofficial).

interesting typo causing this issue...

but, the dev seems just replace
if (pubCoinItem.denomination == libzerocoin::ZQ_PEDERSEN && pubCoinItem.id == pubcoinId && pubCoinItem.nHeight != -1) {

etc by

if (pubCoinItem.denomination == libzerocoin::ZQ_WILLIAMSON && pubCoinItem.id == pubcoinId && pubCoinItem.nHeight != -1) {

etc

isn't this will cause problem if you sync from scratch??

the correct way is to do a fork at given block height.

what is it?
https://chainz.cryptoid.info/xzc/block.dws?21894.htm

Sooo... if fork is at block 22,000, doesn't it mean the bug is still there until the block 22,000? So coins could be still minted and dumped? Do I miss something?

still something wrong with the rich list on https://chainz.cryptoid.info/xzc/#!rich
there's no zcoin blockchain showing the real number of coins circulated. I think the devs should pay some collected coins to find some other coders to do this.

i think you need to go do some reading about what libzerocoin actually is and does.
your comments literally make you look retarded.

Looks like xzc.maxminers.net is having some issues and not allowing coins to be withdrawn.

Might want to avoid them until we hear something from the owner

Surely not.
This coin has very high potential : 0,05 or 0.1 btc without problems (x 50), and you know that : you want that people are selling and dump the price for buyig at low price

I know buddy but it looks like the perfect opportunity to take out the weak links. Wouldn't you agree?
