so when is going to happen the hard fork?, I just want to transfer my zcoins to my personal wallet before

and why miningpoolhub always shows less hashrate than i have?

2x GTX 970, miner shows 2042 kH/s, pool shows 1491kH/s
Ryzen 1600X, miner shows 450kH/s, pool shows 224kH/s
i5 7300HQ, miner shows 349kH/s, pool shows 93kH/s
GTX 1050, miner shows 495kH/s, pool shows 194kH/s

why?

suprnova reporting pretty accurately 1070 ~1300kH/s 1080ti ~2500kH/s

with these stats not really worth mining at the moment. I believe in this project but bills need to be paid Smiley

what are u mining now? i was looking at signatum but its not profitable anymore and zcash consumes a lot.

Crypto is the separation of Power and State.
I'm writing this in my personal capacity not as community manager and my experience as a lawyer and this is to answer the accusation that founders are just swimming in their founder's reward. This is not based on any inside info but my own deductions. For marketing, although i'm not privy to how they spend it, you can see the ads that are popping up on Zcoin so there's some marketing ad spend going on there.

But let's get into the nitty gritty which I think a lot of people are not thinking clearly about.

First of all, Roger Ver's investment is real. It has been disclosed EXPLICITLY in bitcoin.com publications (which Roger owns), confirmed by other independent members approaching him directly, regularly posts on his MemoryDealers account in Reddit in Zcoin and created a sub-forum for it in Bitcoin forums. He still remains invested.
https://news.bitcoin.com/zero-knowledge-zcoin-launching-soon/ (see the disclaimer)
https://www.reddit.com/r/ZCoinProject/

First of all there were definitely certain agreements in place when obtaining investor funding for Zcoin (or as it was then named Moneta). This is what made the project possible in the first place.

It is common for these investors to choose to remain anonymous. Only Roger has stepped forward to confirm he is an investor but I don't think you can blame the founders for not disclosing the others especially since the investors are the one who funded Zcoin and their wishes should be respected. Note that backing a privacy coin can be controversial and not everyone may want to come forward. With Zcash, which is a much more high profile investment with serious marketing dollar, there's bound to be more investors who are willing to be public.

Now to the next point, I think it's naive to think that these investors didn't have certain stakes in the growth and reward of the coin. They need a return on their investment. With no premine, there's the founder's reward. The most logical thing is to assume that some investors are entitled to certain payouts. The whole project started when it was Moneta in 2015 and much time has passed and only about one month back was it launched. Now that a milestone has been achieved (coin launch and listing), some investors may want to recoup part of their investment back while others decide to hold. Where would this payout come from? It may be, to be paid in XZC or it may be 'interest' on their investment or a share of the founder's reward. If you watch Shark Tank, you'll know what I'm talking about. This also makes sense on a contractual standpoint.

Gary and Poramin both mentioned NDAs which are also common and they may not be able to disclose the identity, the size of the investment and their entitlements from their investment. Now they are asked to explain the wallets being drained, but bound by the NDA, now you can imagine the situation they are in. In frustration, Gary said well when Zcash is transparent about their expenditure, they will be too which was received negatively but the fact is a much larger project like Zcash that's involving a lot more money is not subject to scrutiny because big names are involved while with Zcoin, the only known big name is Roger. Again, Zcoin's funding is i think many many many many times smaller than Zcash's and yet I think it is impressive they managed to get out a WORKING implementation of Zerocoin and minting.

Bounties are also being paid for website design, coding work, community management, recruitment activities, marketing and also with important partners to increase adoption.

If you follow their slack you know that Poramin is full time working hard to implement MTP and improve Zcoin and I'm in almost daily contact with Gary and Poramin.


WARNING: BolehVPN is at best a scam and at worst a honey pot.

Exhibit A is the post above, where Boleh's lawyer kisses Roger Ver's ass until his lips are chapped.  Embracing a bad actor like Bitcoin Judas is a red flag.

Exhibit B is BolehVPN's embrace of the instamined scamcoin known as Dash (alias Darkcoin, Xcoin) despite its fake privacy theater and rejection of Monero's military or better grade crypto.

Exhibit C is BolehVPN's lawyer wittering on about obvious scams like Zcoin and Zcash, as if one of those scams is better than the other.

AirVPN.org and Cryptostorm.is are both world class options if you want a real VPN that is not associated with scumbags like BolehVPN, Dash, Roger Ver, Zcoin, and Zcash.

Can someone please elaborate what this might mean in detail?

" Full TOR support on Zcoin with the new Bitcoin Core with also ability to restrict to exclusive use of TOR nodes ". Would that mean access to users in TOR blocked countries can still use TOR via the ZCoin wallet to transact with ZCoins?

If not what is  the significance?

What this means is if you only want to communicate to nodes and peers on TOR, then you can specify this.

Users in TOR blocked countries probably wouldn't want to use this or they can do this through TOR with obfs4 bridge.

We just completed our first mint and spend tx on main net with the new core Cheesy

Just a few more clean up !

We've also redone our OP. Hope you like it!

Our spend transaction on new core:

Some development updates:

Poramin has just pushed in our private repo the fixes needed to implement the Zerocoin improvements and fixes.
Tim Ruffing has pushed the the fixes on libzerocoin as well.
Tim is now looking through Poramin's code to ensure it works as intended and Aizensou and SN are working to integrate the Zerocoin improvements into the new core upgrade 0.13.

There will be an academic paper published as well to detail these fixes so that other Zerocoin implementations (if there are any other original implementations) can fix them independently and contribute to Zerocoin research.

Our new Zerocoin code will be open sourced in due time but may not be done immediately.

We are still weighing our options here as a lot of hard work and resources was put into this and all these fixes are backend which are not quite visible to the user but are important to improving the Zerocoin protocol and its security.

No Open Source ?

Can you expand on this , it's too serious to be mentioned lightly

There was some debate as to whether to allow other coins to immediately take advantage of the improvements we are making to Zerocoin and we know there are a quite a few coins out there just waiting for us to release this. Hence we were thinking maybe to delay the open sourcing by a few months and this would be balanced as the academic paper detailing these fixes would allow others to be aware of the issues and just not the code to immediately implement it. These type of steps aren't unprecedented as coins such as Dash initially closed source their Dark Send feature and NEM still has its NIS infrastructure remain closed source despite commitments to open source it.

However after discussion our team remains committed to open source and the changes we do to Zerocoin will be available when the new code goes live. We remember that without Bitcoin's open source and the researchers' work in coding the initial libzerocoin, there will be no Zcoin. So no need to worry about it, the releases we make will be all open sourced and subject to public audit/scrutiny.

Good news. In the end it's the only way to go. Open source also attracts new devs and community. I think a growing ecosystem is very crucial to the success of the coin.

If anyone wants to see how Zerocoin transactions look like on the blockchain:

Check out a sample mint transaction where 50 coins go into a blackhole.
http://explorer.zcoin.io/tx/b827e91bee75e4abae8590206b088f05f6b9c563dc56e5e71c42da9523ebcccd
https://chainz.cryptoid.info/xzc/tx.dws?b827e91bee75e4abae8590206b088f05f6b9c563dc56e5e71c42da9523ebcccd.htm

This is a sample spend transaction where 50 coins come out from the blackhole and have no linkage with its mint transaction or any history at all.
http://explorer.zcoin.io/tx/d75cd4bfae85bc278900eb4728f71eedea1dec2a16d3f18551dfcd43b413ac07
https://chainz.cryptoid.info/xzc/tx.dws?d75cd4bfae85bc278900eb4728f71eedea1dec2a16d3f18551dfcd43b413ac07.htm

The point is that the 50 coin from the Zerocoin spend transaction could have come from any of the people who minted 50 coins giving it very high anonymity.


So does this mean that the five 100 XZC transactions that I minted will enable others to also use that quantity of coins to mint/spend? And if so, will my coins that went through the mint and spend function get any confirmations then? Its been over 2 months now at zero confirmations, and I would like to know if there is any chance of them coming back/getting confirmations?

Thanks for your time.

They always come back... but wow, 2 months is bad. The artificial limit of 1 spend per block, which was put in place because confirming spends put too much performance strain on pools, is probably what's to blame here.
As I understand it Znodes will be there exclusively for this purpose - to confirm zerocoin mints/spends - so at the latest when they launch is when you should get your confirmations.

For a brief overview of how different privacy blockchain mechanisms stack up (including Zerocoin as used in Zcoin), read the post I made here:

Any update? This coin is sitting in my wallet in the last 8 months. I need to  know this is been worked on otherwise..... Please dev what is the latest?

https://twitter.com/zcoinofficial/status/902733399026044928

Cheesy

Core upgrade is still being tested to make sure it's ready for release.
The core upgrade is actually very big and addresses many of the complaints and user experience issues with Zcoin and greatly improves reliability, improves TOR support and a huge number of other things.
Remember Znodes REQUIRES the core upgrade.

Zerocoin and libzerocoin fixes/improvements coming soon too.

There's some background work we are doing on MTP. Basic CPUminer and Nvidia miners are done but still awaiting the final paper but we want to have all the basics ready to do the necessary modifications once the final paper from the MTP authors are out. We are hoping it won't be too drastic of a change and merely parameter adjustments.

Has there been any discussion about how many ZCoin will be required to run a Znode?
