Privacy-enhancing Technology: Zerocoin Protocol

In Bitcoin, all transactions are broadcasted on a public ledger. Research has shown that external information, such as publicly announced addresses, can be used to link identities and organizations to transactions. The default reuse of bitcoin addresses exacerbates this problem. Furthermore, the same type of mechanism used to break privacy in social networks, such as the analysis of social network topology, can be used to break privacy in the Bitcoin network.



Bitcoin and preceding alternative cryptocurrencies have attempted to solve this problem through the use of transaction mixers or ring signatures. However, there are a number of drawbacks to these proposed solutions. For one, a malicious or compromised member of a mixer or ring signature can break privacy. Furthermore, the anonymity set is a key metric to understanding how private a cryptocurrency is. The anonymity set in formerly proposed solutions is limited by the size of the mixing cycle or ring signature. Each mixing cycle or ring signature is limited by the number of transactions per cycle, which is transitively limited by the the block size of the cryptocurrency. Thus, the anonymity set in previous attempts at privacy tends to only be a few hundred transactions.

With Zcoin, the anonymity set is on a dramatically higher magnitude. Instead of having an anonymity set limited to the few hundreds, Zcoin has an anonymity set that encompasses all "minted coins" in the Zcoin system. The magnitude of the anonymity set is on the order of millions, rather than hundreds - it makes all previous alternative cryptocurrencies aimed at privacy obsolete.

Zcoin solves the privacy problem found in all previous cryptocurrencies. Zcoin implements a protocol called ZeroCoin, which allows users to have complete privacy via Zero-Knowledge cryptographic proofs. Zero-Knowledge proofs allows one to show ownership of a Zcoin coin without having to reveal which coin one owns. The original Zerocoin paper can be found here

the coin fork the zerocoin?

im ready for translate bonties :)

I join here what for, god luck.

I am not the developer.

Go to https://zcoin.slack.com and maybe ask there.

Lol in wallet mining ?

another fucking scam that's trying to capitalise in on the fucking Zcash hype

what algo is this ?

I believe is Scrypt-N.

They state Scrypt-N on the homepage, but it seems to be lyra-2 when you look at the (rather old) codebase..

Another coin that wants to ride on the waves of zcash :)

Why can't they even wait for ZCASH to launch first and see the success before all these copy cat coin flying arround. It will be interesting to see what happen to these coins in general

Yes, today's second zcash hype clone coin. Don't buy , it is a scam.

Its some special Lyra2 algo. Can't use Lyra2RE, so only CPU mining for now.

looks very similar to this project:  https://bitcointalk.org/index.php?topic=1604526.0

I am not the developer of this coin. Please stop PM asking about Bounties and such. I just found this on Reddit and it wasn't posted here before.

There was a fork that changed the algo from Scrypt-N to lyra2 due to ASICS dominating the network.  It's a lot different than zcash.  Similar name though.

Also, the dev was on Let's Talk Bitcoin the other day and created Vertcoin.

Selling ZCOIN @ 0.01  btc each.

The developers of this coin used a trusted setup to initiate the zerocoin protocol instead of opting for the trustless RSA-UFO system outlined by the anoncoin developers.. IMO this coin was dead before it was launched. I stopped mining this coin as should everyone else. The possibility exists that the devs could mint an unlimited amount of zcoin and dump it into the market if the coin ever gained any kind of market share. Unless you trust that they won't.

"When a zerocoin is minted, the coin is added as a member to the set of all zerocoins by way of a one-way cryptographic accumulator. In order to prove later that a given zerocoin belongs to this set, during the initial setup of the accumulator, it is necessary to define a number N (or a set of such numbers) that is the product of at least two distinct prime numbers; this number becomes the accumulator modulus for the Zerocoin implementation. If the prime numbers are large enough, it would be infeasible for any party to factor N. However, any entity that knows all the factors would be able to bypass the security of the system and forge zerocoin membership proofs; it is impossible to verify that the factors were not saved by the generating party after multiplying together to form N. Anoncoin solves this setup problem by using RSA UFOs (generalized RSA moduli of unknown complete factorization) for the accumulator moduli which can be generated in a trustless manner, meaning there is never a time when the factors are known to any party; the setup does not require any trusted third parties."

-https://wiki.anoncoin.net/RSA_UFO

Additionally, the circumstances behind the launch of the coin are also questionable. No ANN made by the devs on these forums where the majority of the altcoin community reside. Ethereum launched an ANN thread here so that should mean something. The article on bitcoin.com is also questionable as it doesn't mention anything about the trusted setup. Either the author of the article is ignorant or is in on it. The lack of an ANN thread here makes me lean to the latter. This coupled with the launch of an ASIC friendly algo to instamine block 0-500 then switched to an algo that can't be used at present by any GPU or mining pool software. For me, there are too many red flags here to consider mining or investing. People on these forums love to get scammed, so help yourself.

its great algo lyre2 cpu mining

ZCoin (XZC) Trading thread..

https://bitcointalk.org/index.php?topic=1634491.0

Where we can minning Zcoin? pool?

lol, listed in novaexchange https://novaexchange.com/market/BTC_ZCOIN/

where can I get the wallet Zcoin

there

https://github.com/zcoinofficial/zcoin/releases

I think ZCOIN price will reach 5-10 usd in mid term.
It looks a great crypto. The first Zero proof knoweledge crypto.

Anyone having to always re-index the db after every launch of wallet?

Nova price is near 0.002. And it's low.

I was bored and fiddled a bit around with this coin, which has serious issues, here are some of them:


1. The Algo is set to self-destruct itself after a certain time where miner's Memory is exhausted or the share finding is simply taking so long that the coins retargeting feature is exhausted.

2. The Blockchain is resyncing everytime you restart the client from scratch

3. There's still lots of debugging code activated which floods the debug files.

4. The zerocoin implementation doesn't really seem to work, did anyone tried this and got it working ?

5. Blocktime is too slow, its like 50 blocks in 12h


Nevertheless, here's a Pool and an external CPU miner which should at least be as fast as the in-wallet miner:

Pool: https://xzc.suprnova.cc

Miner: https://github.com/ocminer/cpuminer-xzc

I've hacked the miner so that the "lyra2rev" Algo works with XZC's ridiculous implementation of crazy Lyra2 - so use "-a lyra2rev2" for XZC mining, of course, the normal Lyra Algo's are broken in this miner now.

And no - I don't have a Windows version nor am I able to compile one.


Have fun :)

Ocminer, can you tell me the command to start the miner in Ubuntu 16.04?

Thanks

Yes, I just fixed the Getting Started page on the pool:

Thanks

I dont know how to compile your wallet,some file is missing from the link to download.Any ready cpu miner.

very helpful owner and supranova really works great for mining good luck hope i can get some of it even i use my old computer.

You mean the wallet or the CPU miner ?

I just noticed you might get an error on some ubuntu systems when compiling the miner from scratch you'd have to add:

./configure --with-curl --with-crypto

in order to get it working correctly

Cpuminer in windows can work or it just in linux version.

Also windows, you just have to compile it

I dont know how to compile.Plesae send instruction.

It's all in the README:

Basic Windows build with Visual Studio 2013

All the required .lib files are now included in tree (windows only)
AVX enabled by default for x64 platform (AVX2 and XOP could also be used)
Basic Windows build instructions, using MinGW64:

Install MinGW64 and the MSYS Developer Tool Kit (http://www.mingw.org/)
Make sure you have mstcpip.h in MinGW\include
install pthreads-w64
Install libcurl devel (http://curl.haxx.se/download.html)
Make sure you have libcurl.m4 in MinGW\share\aclocal
Make sure you have curl-config in MinGW\bin
Install openssl devel (https://www.openssl.org/related/binaries.html)
In the MSYS shell, run:
for 64bit, you can use ./mingw64.sh else : ./autogen.sh # only needed if building from git repo
LIBCURL="-lcurldll" ./configure CFLAGS="-march=native"
# Use -march=native if building for a single machine
make

Pool Efficiency   29.23%, is there any problem or just stats messed up because of low hashrates?

Thankks

Some folks are trying to mine with scrypt and/or any other algo

Can you compile and post a binary? I am getting some dependency errors.


Or help me compile properly. I am getting the CANNOT FIND -lpthreadsGC2 when the pthreadsGC2.dll is in MinGW/bin/

The last time I did anything @ windows was when Windows 7 came out :)

I can tell you anyhting or compile anything under Linux but I'm sorry, I can't help for Windows.

Yeah it compiled in Ubuntu no problem just trying to get it for Windows.

Also when you were writing this algorithm, is it really Lyra2 or something else? It looked like some pyminer.py was doing the mining and the algorithm was more along the lines of SHA256 than Lyra2.

Hmm I've tried to get a VM running to compile the miner but hey.. It's freakin' harder to get the build environment going under windows than getting a stratum pool going for zcash :)

This algo is pure Lyra2 with some crazy values.. Yes I used python for testing and then switched over to C(++) as testing scripts are written in a snap in python.

Whereas Vertcoin uses some special "light" version of Lyra2(RE) it was a chained algo (like X11) were Lyra2 was one of the algos in the chain with quite light values, so it wasn't so hard to mine.

Here, I'm not sure if the devs really know what they were doing, they dropped all the chained algos and cranked the Lyra2 "hardness" waaayy beyond maximum and that makes the algo so slow. As they are also using the block height as a difficulty factor in the algo, it gets harder with every new mined block. At some point blockchain height will reach a value where it will be too hard to mine and the chain will stall - it will probably be forked before that happens.

When you are testing in Python, do you copy over the exact code to C or do you have to modify it a bit?

Because I always wondered how people test all those C algos for CPUs or CL kernels for GPUs since they would have to compile the entire program just to debug.

 

Somebody sent me a compiled version of the Miner:

https://github.com/ocminer/cpuminer-xzc/releases

However - Please Virusscan the Miner, I cannot guarantee for the file !

@adaseb:
The good thing about python is, it can use c modules, so yes, I simply copy over the code 1:1 and modify input and output ... Thats about it.
Then you use an input string like "deadcafebabedeadcafebabedeadbeefbeef" and let it run through your hashing function in python which spits something out
like 00abcdef012309aaabbbcc313921aaaaabbbb33232323 - this is the hash which you then compare with your stratum module and if both hashes match - you're basically done and got a new algo ready. (this was a veeery shortened version of whats actually going on.. Sometimes it takes 2-3 days until that stuff is good.. with A LOT trial and error :))

Virus Total 9/55

https://www.virustotal.com/en/file/e99e5f9a0b1584f9ddc30b6e649a9abfd7293957ec054b816571c7a22d522f8b/analysis/1475712845/

Yes, but those results seem to be the BitcoinMiner Results.. i'm not 100% sure but they look "ok" to me.

Can anyone tell if he's mining with the Miner on windows ? all good ?

Stratum connection failed:

Me was minning on the miner all is good.

I updated the original post with more info. If you have anything you want me to add then PM me or post here.

I figured it was good when the original cpuminer got like 48/55 haha. I used it last night and this morning I only had 2 XZC pending in my account.

Could just be the diff growth though.

what pool

Suprnova

really do solo mining?cpu i7 3630qm I get 0.03 kH/s on the miner for the pool.I think it is very little for 4 hours 0.7 XZC or is this normal?

Maybe waiting for the gpu miner.

Probably won't be available until some decent exchange lists this coin and it develops a modest market cap. Too much coding for now.

mining rate of 1kh/s is normal? and what a day it is the coin?

how many of my shares is one share in the pool?
I find the shares and the pool shows zero

1 share from the miner = 256 shares in the pool, but the important factor is your overall difficulty, not shares.

I find the shares and the pool shows zero
I don't know what your math but it seems that for some blocks no payout

Look in "Statistics-> Round Transactions" and find your username there.

Yes, "Shares" is 0 for some rounds, but you still have reward because difficulty is calculated, not the shares, thats what I've tried to explain you.

Since the dev posted an official ANN, I will lock this one.
