Network hash rate dropped quite a bit

Not so strange. Myself I've been getting almost no new coins at all with the recent difficulty and moved all cpu's to RieCoin instead. I might consider moving gpu's to DRK if MAX continues to drop though..

I wasted 6 hours mining maxcoin, max keiser needs an ass kicking.

I'm sure we'll get the Max bump soon enough

this isn't good enough.. I'll improve it later. the top font looks unprofessional.

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.)

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!

[Lebubar]

Yes it's really nice.

Only small thing with the 00110 : pixelized? aliased?

Expect one hell of a jump after alpha tests tonight  

THIS is the news, as much as I like logo design talk.  THIS is what's getting me excited!  Great work!!

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

01100100 01100001 01110010 01101011 01100011 01101111 01101001 01101110

So right now this is about the same profitability as Max?  Is C-Cex the largest exchange?  I don't see much volume there.

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!

And what is the difference between Darkcoin and DarkWallet's Coinjoin implementation?

And what is the difference between Darkcoin and DarkWallet's Coinjoin implementation?

is darkwallet running already? i thought its just a project.

[eduffield]

And what is the difference between Darkcoin and DarkWallet's Coinjoin implementation?

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.

its pretty much complete the dev. team is just finishing some last minute bugs.

can i use the same signature as you?

Yes but maybe they have some specs released?

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.

[essjayeire]

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)

PM me

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.
