Topic: [ANN] Zcoin (XZC) - Implementing ZKP privacy without trusted setup - page 164. (Read 663229 times)

Hi,
I was waiting for the price to drop. I believe this coin has a good future: its MCap is 10x less than its competitors, and it should not be the case.

Anyway...I am in now :-)

I would like to see some hashrate comparison on ZCoin, not easy to find.

Especially CPU comparisons would be interesting

I 've tried with an Intel i3 7100T @3.40 Ghz ( 4-threads, not sure if it's quad core too),  and it mines at 280 KH/s , while a GTX 1080 is about 2x faster but it consumes 180/200 W while an i3 consumes like 70 W if i'm right, it's like 1/3.
EDIT: i was wrong, it consumes 35W ( http://www.cpu-world.com/Compare/489/Intel_Core_i3_i3-7100_vs_Intel_Core_i3_i3-7100T.html )

So my CPU has better performance/consumption ratio BUT not better hashrate.

Maybe you tried with an i7 and it outperforms even a 1080 ?

Which processor did you try and what hashate did you get ?

I realized I get way better hashrate using my CPU than my graphics card which is great, it's really hard to find coins that are CPU mining friendly these days and once MTP is implemented hopefully Zcoin will get more attention.

Nice to see that 17 bitcoin buy order on Bittrex, someone wants to get some Zcoin in a big way and at a lower price.

Bootstrap?

http://znode.io/

The development team should try to contact the Korean and Japanese markets, the two countries have a very large bitcoin trading volume. Will contribute to the development of zcoin    Trading volume is too concentrated in btc38

The latter. They might not be able to provide a bootstrap, but really, nothing about this project is more important than the tech.

seems like a big price move in to negative territory. Looking for support level

Price is dumping quite significantly, any rumors behind this or just shaking weak hands? I'm guessing the latter.

18 connections to network
literally just spent a week getting synced
gets stuck again an hour later
...
 

how come after a few days of finally catching up my wallet always falls out of sync and the network is too slow for it to ever catch back up, super annoying??
i literally just downloaded the full blockchain 2 days ago, it took 3 days, finally got it to sync, now its stuck again at block 47013
and i need to go through this whole 4 day process again?
why does this coin constantly get stuck ......

it's quite long for MTP officially released I'm really impatient for this coin. I just thought it was released one month ago.
I need the exact time for this algo? this delay will decrease the trust from the investors in the future.

Thanks for sharing this post about the difference between privacy on the blockchain and hiding your ip address. it's very good article

Note that MTP although reference design is 2 gb only, quoting Dmitry: The design goal of MTP is to create a PoW which would handle 4,6,8,10 GB fast enough (within a few seconds), which I think is impossible for CPU-based Equihash solvers.

It's actually not that long of an ETA and it's totally worth the wait, better buy it now while it's cheap  .

We hope this post sheds some light on the difference between IP protection and privacy on the blockchain.

If the work progress in accordance with the current, MTP may be in November to launch the mainnet,waiting time is very long. According to the road map, this year also need to complete znode, this year's road map do not know whether to finish on time.

Preimage to be revealed in the fullness of time.

Core Upgrade - 13 August 2017

We are happy to announce that Zcoin is almost ready to be deployed on Bitcoin Core 0.13 and will be released soon. One of the benefits of being on a Bitcoin base means we can adopt benefits of Bitcoin improvements relatively easily.

The upgrade of the Bitcoin Core from 0.8 to 0.13 is a culmination of several months of work and improves on many aspects of Zcoin with node connection reliability and sync speeds drastically improved. Sections of the Zerocoin code had to be rewritten to accommodate the core upgrade and opens the door to a whole range of improvements that we can adopt from light wallets to hardware wallet integration.

Some other improvements from the core upgrade:

• Support for blockchain pruning
• TX malleability fixes
• Memory usage optimizations
• Privacy: Stream isolation for Tor: This release adds functionality to create a new circuit for every peer connection, when the software is used with Tor. The new option, -proxyrandomize, is on by default.
• Hierarchical Deterministic Key Generation
• The core upgrade also allows us to work on implementation of Znodes. We will post an update once we upload the code on Github and also have the binaries available.

MTP

We are very pleased that has been a lot of academic debate on MTP the first being Dinur & Nadler's paper which we had patched a quick fix to it as a temporary solution. It was this paper that prompted us to launch our USD10,000 MTP Audit and USD2,500 MTP Implementation bounties to further encourage research into MTP and also prompted a slew of changes to our MTP code.

Since then, we have also been given a draft copy of research from Fabien Coelho at Zeronote Skunkworks that brings new memory hard PoW proposals to improve MTP and to counter known attacks to the scheme and is currently awaiting feedback from the authors of MTP.

We have also received on the 11 and 12th August several submissions from Marc Bevand to the  MTP bounty which require further investigation and also further scrutiny into the proposed fixes. You can view his submissions here which are currently being validated.

Alex Biryukov (one of the authors of MTP) has mentioned in light of Dinur & Nadler's paper, that MTP needs further work  and we have been informed that they are planning to continue work on MTP in September and October which aims to address these new academic papers and research and to further improve on MTP including proof size optimizations.

As such, although we are technically ready to migrate MTP in its current form to mainnet, in light of the above discoveries, the responsible thing to do is to hold off on deployment on mainnet until the revised paper is out and there is confirmation that the attack vectors are closed as opposed a temporarily patched MTP that will be almost certainly be changed again. We apologize for the late notification but it was not a decision we took lightly but we are thankful that the research came to light before deployment of MTP on main net.

MTP in its current form is completely functional and continues to be able to be tested on our Testnet. You can compile zcoind from our Github mtptest branch and also mine with its inbuilt miner. You can also ask from our Slack if you need binaries to the MTP testnet or get some testnet ZCoins.

You can view our Testnet explorer here: http://testnet.zcoin.io:3001/

We remain committed to MTP as long as it remains a viable PoW and we continue to refine our code to make it easier for third parties to work and read with. We thank you for your patience and understanding especially when developing cutting edge technology.
