Just find that this one lacks one bit. Apply also to onetime's version.

Edit. You got it first Speedie.

I’ve heard some chatter and misconceptions about the difference between Darkcoin vs Zerocoin, so here’s a write up about the pros and cons of each approach and what they do differently.

Darkcoin

First off, most people start by asking is DarkSend actually real and does it work? Yes! Checkout the development progress here: https://bitcointalk.org/index.php?topic=467857.0

DarkSend is based off of Greg Maxwells original idea called Coinjoin, with some added improvements and decentralization. The decentralized approach is important because the logic is self contained in the client, which is managed by the users themselves. This is a trustless solution.

Darkcoin uses the base transaction layer to sign it’s transactions in much the same way that Bitcoin does. The mathematics are tried and true and have been used for years in computer security and banking.

Transactions will be grouped together and the same cost as sending transactions on the normal network. Both DarkSend and normal transactions will be available to choose from, but at some point we might default to DarkSend (and go Dark).

It’s also worth noting that this approach doesn’t bloat the blockchain at all either. Transactions are the same size as the would have been.

Zerocoin

The approach Zerocoin takes is to use some exotic mathematics to hide the identity with a zero-knowledge proof. This allows a higher quality of anonymity, but also could have some unforeseen hole that will be exploited later.

Checkout this link to see the mathematics I'm talking about: https://github.com/Zerocoin/libzerocoin/blob/master/AccumulatorProofOfKnowledge.cpp

Zerocoin's proof of work is in the 344 byte range, which was reduced from 50kb in Mathew Green’s original work. These proofs must be stored in the blockchain for each transaction that goes through the network for confirmation purposes and the ledger history, so this will cause a lot of bloat. There is also a need for these proofs to be processed by the networks nodes, being larger will cause more intense CPU usage with smaller transaction rates.  

Mixing Services - (Fedoracoin, Anoncoin)

The revolutionary feature of Bitcoin was not the currency, but the decentralized ledger. Mixing services are great at what they do, but any hosted service is inherently centralized and requires an amount of trust of that entity. Services setup in a centralized way can also be compromised without users knowledge.

---

I think the Darkcoin approach has the best mix of features, with the least risk and it’s decentralized. So we definitely have our place in the market.

EDIT: I accidentally copied misinformation from a bad source on the internet, I was looking for original sources this morning trying to vet my post and found it was wrong. Sorry!

It's not in the native client, it's a browser extension and it's not decentralized. In the world of crypto decentralized solutions will always win, we need all of this technology to be trustless.

Appreciate those posts eduffield.

Have you by chance expounded upon the "encrypted transaction network", or at least gave a brief outline/framework somewhere? I'm curious what your vision is for this. I think I've read every post in this thread but I may have missed it.

I can do the website up if needed as that's my day job. New to mining learned a lot off this thread. Unfortunately can't afford any GPU miners and using EC2 is not profitable. Only way I can contribute to the community and happy to help. Might be even able to move to my VPS if hosting is an issue (that said if it attracts any DDOS attacks I might have to shut it down as to not affect my clients)

I'm not dead set on how I want to implement this yet, and have a few separate ideas.

Before implementation: proxies have always been supported, which would do the same thing. They just require a bit more work on the users part to setup.

Implementation #1: Building in something like tor to use an existing network to secure communication between the nodes and yourself. The problem is this causes everything to slow down substantially.

Implementation #2: Turn the Darkcoin network into a proxy network and pick a node to securely relay through. This could even have N hops before reaching an exit node and would only work for internal system messages.

Implementation #3: Unencrypted relaying using a "Pass this message on to 1 node (and tell them to do the same) you're connected to or if random number > X broadcast", so the message would hop multiple times before it was actually broadcasted by the exit node. You would never know who the original client was because N hops would be random.

Implementation #4+? I'm open to other ideas.

any community ami's for amazon ec2 for the rest of the world setup?

I'm having trouble doing it myself.  I don't know putty, having trouble getting minerd loaded properly.
I setup a few with the tuto that send you in previous post..
I can help you but be more specific of your problems or where yo re blocked..
Updated with the version 1.3 of minerd.. It s working on amazon.

If you succeed to connect to your instance via putty just follow those step :

sudo apt-get update

sudo apt-get install -y build-essential m4 libssl-dev libdb++-dev libboost-all-dev libminiupnpc-dev git automake libcurl4-openssl-dev

git clone https://github.com/elmad/darkcoin-cpuminer-1.3-avx-aes

cd darkcoin-cpuminer-1.3-avx-aes

chmod a+x autogen.sh

./autogen.sh

./configure CFLAGS="-O3 -march=native"

make


The one thing that is giving me fits is having a .sh script start right after re/boot. I tried using

#!/bin/bash
cd ~
./wnc.sh

in the user data (kind of a cloud sript, I guess) but it seems to work intermittently. I know there is some way to tie in to init.d, but my attempts have not worked.

I adjusted the colors and altered the design in the center of the logo.

(The subtle blurred separation in the dark diagonal bar across the center is intentional to represent anonymized un-linked transactions.)

-onetime




EDIT:      

This is my fav so far, I like the clean / polish of it, and the dark blue. Nice touch with the blured seperation.  Thanks to all who are helping this coin!

I like it too. The binary word at approximately 8 o' clock is malformed though (7 digits not Cool. Maybe this would be better:

use crontab!

crontab -e

then add

@reboot ~/wnc.sh

When host reboots it will start that. Put that in the users crontab, the one you login with.

Network hash rate dropped quite a bit

Except one hell of a jump after alpha tests tonight  Grin

I'm happy it dropped  Grin

More coins for me to mine !!

hehehe Be nice for it to dip below 75 for a while... Smiley

OK, cool. I'll give that a shot right now.

EDIT: nope, it still doesn't work. ... Maybe it has something to do with the way amazon initializes their AMIs? I can't believe there is such a simple way to do this in windows and not in Linux... I must be missing something somewhere...

EDIT EDIT: I take that back - it works on some instances and not on others... seems like it might not work as well (or as fast?) on the tiny instances....

Man, I really should get back to work! Tongue

Tbh I think the darkcoin coin image looks too much like a tiddlywink lol, it looks like it's made of plastic, which is of low value.  If it could be made more substantial looking, more heavy/sold and made of a precious metal rather than plastic people would find it more desirable.

Any bounties for DRK if I could get a big crypto merchant to accept it? I'm asking because A: I like where this currency is going and B: I cant seem to mine fast enough so a bounty would help jumpstart...and I know a few owners.

Time to stock up some darkcoins, looks like it's bouncing back from the dip... I wished I've bought more while it was @ 0.0005... but hey, never too late.
