I say we just call it X-11. Sounds like a top secret project or something. Or we could just call it CPUcoin  Great idea! You win the 1000XCO prize. I bought X11coin.com and I'll point everything over later. What's your X-11 address? |

We're decided we're going to be changing the name of XCoin to something else. It's already kind of confusing to search for XCoin on Google and we want to differentiate ourselves from the other company using the name.
We thought it might be fun to actually let the community suggest the future name for XCoin. Any ideas?
Ps. The blockchain will stay intact, and it's merely a domain name change, some strings in the client, and the images.
Ps2. The addresses will still start with X, so keep that in mind for the suggestions
The winner gets 1000XCO! Let the competition begin.

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. |

9 blocks till RETARGET (0.74 difficulty)

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

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?
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. |

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. http://www.xcoin.co/coinjoin1.pnghttp://www.xcoin.co/coinjoin2.pngThat'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,  I also feel that if you were to explain it, there would be great interest from the public! Thanks! 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. |

XCoin (XCO)
 Proof-of-concept for COINJOIN technology We're happy to announce we've made huge progress in implementing coinjoin technology as the default method for storing transactions in the blockchain. We 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.   This is just the beginning of our plans, checkout our thread for more information: https://bitcointalk.org/index.php?topic=421615.0 |

it returns quark blocks and addresses... fixed, they were actually Xcoin blocks/addresses... just the first letter was set incorrectly |

Done! Happy for a tip XkGF4JLWG3Jfksyy1hz289vuAQmzeRHjqq  Haha, ok I'll bite. 20 XCO for an upvote&comment on the post above. I'll send out the coin when I get home tonight. Post back when you finish with your address! LOL, thanks  I really don't need to be bribed 'cause I actually like the plan for this coin. I'm trying my hand at remaking the logo (actually, I like the coin, and am only trying to make it look more realistic, and then I'm going to try my hand at animating it, but I'm not fast at this stuff and have kids, etc... LOL... so may not get it done in time, but will try. I actually just remade the logo this morning, check it out here: http://xcoin.co/xcoin_500px.pngI'm a software engineer, not a designer though. Maybe we should have a contest or something |
