I just setup a block explorer using Abe, check it out:

http://explorer.xcoin.co/

it returns quark blocks and addresses...

fixed, they were actually Xcoin blocks/addresses... just the first letter was set incorrectly

So, HUGE progress this morning! I have a proof-of-concept of the anonymous transactions working on testnet! Here's some screenshots, these were 3 separate transactions sent to 3 different addresses, at separate times.

Notice how you can't tell who is sending to who. Soon all blocks will only have 2 transactions, 1 for the creation event and a merged transaction with everything else.

Thank you for the tip, eduffield ! Grin

Anyone looking for a pool, come over to http://xco.lotterymining.com !  We're a small pool, and I would like to see it grow for two reasons.  First, to have a more steady income, and second, to make Xcoins well diversified to avoid the pitfalls of having one group getting close to the 50% mark, destabilizing the currency's integrity.

Don't forget, There is a 20 XCO reward for the first (20? I think) people to join and mine for at least a week!  Plus, a lottery drawing every week of which an extra 100 XCO has been donated for the first 4(If I remember correctly) weeks!  First drawing will be January 28th, but you have to be actively mining to play!  Also, remember 50% of the fees go toward the lottery and are paid out to the lucky winner each week.  So come join the fun, and build up our pool!!!

Also, remember;  a smaller pool gives larger rewards, but less frequently.  It all adds up to the same thing, but we'd like to grow so that we get rewarded more often.  Please check us out Cheesy  (BTW, it's not my pool, I'm just in it Smiley )

That's so cool you got it working, but could you explain to those of us that aren't knowledgeable what it all means please?  I understand how it's supposed to work, I just don't understand how to read the chart,  Cheesy  Tongue

I also feel that if you were to explain it, there would be great interest from the public!  Thanks!

What is the status on GPU mining of this coin?

As it is 11 hash functions, it should not be probably that hard, quark uses 9 rounds from 6 hashes and there is already a GPU miner for it - not a good one though, it is closed-source, steals 12.5% of the generated coins and does not give that much of an advantage over CPU as there is for example for SHA256, but it is a proof that GPU mining is possible.

Anybody tried either working on GPU miner or at least examined the feasibility of creating one?

CACHe mining pools : http://cach.catcoin.cz - 1.5% fee, early payouts (buffer used to pay even for unconfirmed blocks - get your mined coins up to 4 days earlier than from other pools!), http://pool.cachecoin.net - 0.8% fee.

I'm sure people have tried. And some might even have it working. But they're probably not giving it away.

you're right, they aren't .. I thought about trying this one. http://satoshibox.com/52e574504c347bf1200041a7  , I got lucky with the protoshares gpu miner I bought last time, I wonder how many people picked up this one so far.

Bitcoin is often promoted as being somewhat anonymous, but the main problem is that if I know your address, I can literally tell everyone you've ever paid. Imagine everyone you met, was able to see everything you bought in your checking account. That's pretty much the situation Bitcoin and other alt-coins are currently in. We need to move quickly to a anonymity-by-default approach.

There are many solutions out there for fixing this and we know how to implement them. But, the developers are very scared of implementing these fixes, with the possibility of bringing down a 10+ billion dollar economy.  So it will take years at the very minimum to do this.

So, that's where XCoin comes into play. I want solve many of these problems that Bitcoin and other alt-coins experience, making XCoin the beta to Bitcoin. The goal is to be years ahead in development, with cutting edge features that would be insanely difficult to pull off in their codebase.

So what progress was made this morning? I implemented a rough version of CoinJoin. The idea behind what I'm working on was originally put forward by Gregory Maxwell  and it's a great idea (if you want to read more, the original post is here: https://bitcointalk.org/index.php?topic=279249.0).

In short, transactions in the Bitcoin Blockchain are stored like this:

"User1 paid User12 the amount 1.2BTC"
"User4 paid User2 the amount 1.2BTC"
"User11 paid User3 the amount 1.2BTC"

In XCoin they'll look like this:

"Debit User1 the amount 1.2XCO, Debit User4 the amount 1.2XCO, Debit User11 the amount 1.2XCO"
and
"Credit User12 the amount 1.2XCO, Credit User2 the amount 1.2XCO, Credit User3 the amount 1.2XCO"

Notice, in the XCoin you can't tell who paid who. But in Bitcoin the parties are linked together. This will be a large step forward to providing anonymity by default.

Wow, it's that open eh?

Still, this example implies that one could still link up the amounts of the transactions to find the end users.  How unique are transaction amounts, and how hard would it be to hide that level?  Is there a breaking up of the payment so that the amounts are harder to compare or something?  Or am I missing something due to the simplification of the explanation?  

At the xcoin explorer site http://explorer.xcoin.co/block/00000000068ff1c40a8cc39b920bc49fcf841fd131805558450efaf8072f5b9c, I can understand this one transaction, I think?  A block was found, created a payout of 122 coins to address 1, which paid out to two other accounts, presumably a pool minus fees?  Is that what I'm seeing?

Now on your sample explorer, it is indeed more complex looking to me.  But I'm not the sharpest tack in the box, LOL.  Could you explain a bit more what is happening?  Thanks!

Yes, you could still use the transaction amounts to track money through the system. This combined with some logic to use common transaction amounts or some other logic like that in the wallet could definitely help. Even with the problems, having coinjoin implemented directly into the client is a huge step in the right direction.

Yeah, it looks like a pool found a block and then sent it to another address, then kept 3XCO for fees?

retarget every 576 block may not be the best according to today standards (with huge miners and multipools coming to rape a coin, mining many easy block and then leaving the coin when the difficulty skyrockets), perhaps consider lowering it while it is still possible (maybe set the retarget to lower value from date like 14 days from today, thus giving people time to upgrade their wallets). 576 blocks (1 day) is not that bad, but if some multipool pumps the difficulty 10 times and leaves, that 1 day of blocks will need to be mined for 10 days by the rest of the miners - some of them possibly leaving and waiting for the diff to go back down again, so it will be even more than 10 days being stuck at some high difficulty.

I definitely agree with you for the most part and I've thought quite a bit about this. Most of the coins having issues are scrypt-based right? So it's the same algorithm and thus it's easy to swap in and out of different coins for a site like middlecoin. However, xcoin is a new algorithm that takes a specialized client, so the people mining it must take some level of effort to set it up.

Also, it even possible to setup a site like middlecoin for CPU coins with unique algorithms? You would technically have to have all of minerd versions for every algorithm on the client's computer and it would have to turn them on and off depending on which one it (the site) wanted to mine. It seems possible, but it definitely doesn't exist yet.

So, while we had a huge rush in the beginning. I believe it should be a slow and steady rise from here on out. However, I could be wrong, who knows. In the case, I'll be more than willing to update the client and lower the retarget to 4 hours or something.

There will allways be the initial rush for new coming coins, but so far i actually think we should stick to the retarget we have.. just me 2 cents  :-)

You're right, due to the algorithm being unique (at least for now), it cant' be picked by multipools with current protocol.

Though with relatively small change of protocol and some universal miner that can do several coin types (sha/scrypt/scrypt-jane/prime/quark/....) that would be possible, but as scrypt coins are now sort of majority in altcoins, I think it is not worth the effort for many to create such an universal miner.

It still leaves the coin a bit vulnerable to sudden spikes, like now.
The diff is supposed to go from 6.1 to 0.7, pretty big downspike (because of the initial rush fading), but goes actually only to 1.5 because of maximal adjustment is 4-times larger or smaller. This leaves us with 2x supposed difficulty for 2 more days ....
In the future there could be more spikes (if you publish a new cool feature or otherwise ignite some interest, people will rush in, mine until the diff skyrockets and then maybe many of them leaves once the hype fades, many of the rest leaving too when the coin becomes too hard to mine, leaving only the core miner stuck with difficulty 10-20 times of what it should be)

This coins has quite a potential for this due to new unique algorithms, so is could be easily hyped ... possibly hyped to death
