Sorry, it was @apurvslam. Wrong quotation code

Zcoin is just rebranding for their other project by the name of Moneta.
So? What's the deal with that? Dash is a rebrandig of DarkCoin, Monero is a rebranding of Bitmonero...
There has been zero github activity for moneta in over a year
And now it is active. Where is the problem?
The fact is that the coin works quite well.

Regarding Zerovert:
Poramin from Slack:
when I released zerovert, at that time, we didn't have investor backup, so only our choice is closed source to make sure no other competitors at that time copy our code and create new coin. as a result, in cryptocurrency world, no one want to take close source software serious as you know. It doesn't go well, and we cannot publish the code either. another reason is the name zerovert, when I decided to use that name because I want the zerovert becomes part of Vertcoin's ecosystem. Turned out the Vert community itself, also doesn't buy that idea. last but not least, we found huge perfomance issue in zerovert for using zerocoin, if you think ZCoin slows during verify zerocoin spen transaction, zerovert event worse. That all the reasons, why we don't pursue zerovert, and looked for investor so we can opensource and use new name doesn't tight to any coins, and fixed performance problem.
PS: Someone said we dump our coin in exchanges, this is FUD, we are pretty sure that if you look at blockchain explorer at that time, we didn't event send that coins to exchange, and didn't sell to anyone, the amount is the same, we spent some to giveaway and translation, which is only small proportion.

Just FYI Poramin already responded to the allegations in Slack:
Concerning Moneta at least what he says is true, Moneta isn't a different project, it's the same project as ZCoin. Moneta was a testnet, not a live currency. It was renamed before launch.

Hey that's me!
Seriously though, based on that web archive article Gary Le seems like a pretty scummy bag, and Poramin was too busy launching closed source pump and dump scam coins to keep working on Vertcoin (which according to devtome article was instamined pretty badly too). Not sure why anyone would trust this dynamic duo with a coin that requires a trusted setup.
Plus they're using the first iteration of the technology, zerocoin, that was developed in part by Poramin's former professor Matthew Green, while zerocash will use the more recent iteration, zerocash (and has Matthew Green listed as a contributor, who actually has a reputation to be put on the line, not too mention Zooko et al.). I wouldn't use zcash either, for issues related to trusted setup and opt-in privacy features, but given a choice between zcash and zcoin, there doesn't seem to be much choice at all.
I've saw a very better coin there in the forums, but I don't remember the name.

READ THIS CAREFULLY BEFORE HOPPING ON BOARD THE HYPE.
If you don't know already Gary and Poramin are the two devs leading this project. There is some good momentum building up as more and more people are become interested.
I too have been quite enthusiastic about the coin. Hell, I have been spreading the word days before it even launched, as seen here.
https://bitcointalksearch.org/topic/m.16331329
But a reply from a dev in the vertcoin thread which he later deleted made me look into it a bit deeper.
https://bitcointalksearch.org/topic/m.16332895
As you can see etang6000, who is leading the vertcoin project now had this to say about Poramin :
"Poramin did create vertcoin, but he also created a few other coins that had huge premines and we're deemed scams . He also was caught doing so pretty shady stuff . He was more or less asked to leave vertcoin or pushed out"
This worried me and I started to dig up further and came aross this AMA from Gary from 2015
https://forum.bitcoin.com/ama-ask-me-anything/i-m-gary-le-co-founder-of-moneta-the-world-s-first-implementation-of-zerocoin-ama-t2408.html
I highly recommend going through the entire AMA.
There has been a lot of accusations floating around them.
They created Zerovert coin back in late 2014 and just when it hit some major exchanges a huge premine dumping took place and the devs never replied in that thread ever again.

Zcoin is just rebranding for their other project by the name of Moneta.
https://news.bitcoin.com/first-implementation-zerocoin-released-introducing-moneta/
They took their old code just renamed it as close as possible to Zcash and launched exactly a month before Zcash's launch to get the most juice out of their rusting project.
There has been zero github activity for moneta in over a year
https://github.com/zebbra2014/moneta/graphs/contributors
Github activity as compared to Zcash https://twitter.com/dmfay89/status/779368584086626304
For those saying the devs will correct the faulty codebase in due time ,well they had over a year to fix it and they did nothing.
Gary has had some other serious accusations thrown at him to which he never gave a clear reply.
https://web.archive.org/web/20141016203212/http://blog.kevinzhang.me/posts/tracking-down-gary-le-the-thiel-fellow-and-dartmouth-dropout-who-tried-to-impersonate-me-an-encore.html

So basically the devs have had a history of dumping and abandoning projects and nefarious behavior.
Bittrex and other major exchanges are well aware of it and would be hesitant to list it anytime soon.
Sincerely hope Zcoin is going to be different than their other coins and it works out for all of it's supporters but due diligence is warranted.

I wonder how many of you know that Vertcoin creator Poramin Insom is coming up with a Zerocash competitor which is going to be launched very soon.
https://news.bitcoin.com/zero-knowledge-zcoin-launching-soon/
http://zcoin.tech/about.html
There is a possibility of zerocoin implementation on vertcoin via sidechains as hinted by him earlier.
https://bitcointalksearch.org/topic/m.9632734
No wonder this coin has been under accumulation for so long!
In before polo troll box gets a whiff of this.

Can someone write what is the best processor / server for mining this coin?

After sync, wallet always stuck on the same number of blocks. What to do?

If you guys have some free time you can easily port a GPU miner for this coin. Search for CPUMINER with OpenCL and modify the kernel to mine this Lyra2 algo with the current parameters.
Just look at the other algorithm C source codes and opencl kernels and make the necessary changes, you can use debug the program to make sure you are on the right path.
However at this moment it seems like a waste of time because nobody knows what speeds GPUs will hash at because of the matrix issue, and nobody knows when the algorithm will be changed. Maybe if it got listed on Poloniex or Bittrex and had large buy support.

This won't work, because the input for the algo is 80 bytes, not 64 bytes as in all the current available gpu miner implementations.
Current implementations use lyra2 as a chained algo, input is 64 bytes because it's in the middle of the chain. ZCoin uses pure lyra2, so it's the only algo or the first in the chain and it needs to hash 80 bytes.
Yes I am just noticing this, the height is the extra part. Wouldn't the fastest and easiest way to do this is just to re-use the current Lyra2rev2 algo and just null the blake256,keccak,skein,cubehash, bmw256 hashes and transfer the target argument from the last hash to the lyra2 part?
This way you don't have to rewrite everything from scratch.
Still won't work.. you need a GPU function for Lyra2 that hases 80 bytes, not 64 bytes
Example:
Hashin:
80bytes80bytes80bytes80bytes
Using a correct, 80 bytes hash results in:
adasebadasebadasebadasebada
Using a wrong 64 bytes hash results in:
adasebadase
The result is incomplete.

As seen in the explorer, the reward for each block is split among six addresses. The miner gets 40XZC plus transactions fees. The other five addresses are always the same, each getting 2XZC.

As it turns out that is the "Founders' Reward": https://zcoin.tech/faq.html#distribution
That and the way this blockchain was launched; it is quite certain that the founders currently hold most of the coins in existence.
On the positive side, the supply is still limited in this early stage, and now lots more people are mining.
So far this seems more like bad planning than any bad intent. And if they are who they say they are on the website, then the developers have identified themselves as people having some potential.
On one hand I wouldn't put any money into this right now. On the other hand I'd mine the hell out of it and not sell at this time.
Zcoin is a strange one that has my curiosity.....

I also started mining slowly this, although I am very curious where will the price go...
For now there are so few buyers and sellers the market is pure manipulation.
BTW, I liked this from the OP "Use at your own risk!" near the exchanges
Mining means you at least pay for electricity, so you put some money into it anyway
Right now the price and the future are so unpredictable, any option you chose is pretty good.
