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.

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://bitcointalksearch.org/topic/coinjoin-bitcoin-privacy-for-the-real-world-279249).
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.
