Here is my implementation of the Distributed Trade processing. http://mymastercoins.com/Orders.aspx?CurrencyID=2Some notes CFSID = Currency for Sale ID. Available = No of Test MSC left for sale. If BTCDesired = 0. Set all Available to 0 (for that Currency). Buying If AmounttoPurchase > Available AmountPurchased = Available Comments are very welcomed =) This is pretty nice. I notice that completed transactions all show as "Waiting for payment" The seller ID's with links are a cool touch - do the existing ID's reference anything specific? |

I'm having probs with the the qtbindings when installing. QT 5 would not work for me at all so trying now with QT 4 and from what I can tell I'm getting stuck at the smokeqtsql install:

I've spend some time trying to package it but ran into a lot of problems. I will try it again but I didn't want to 'waste' too much time on packaging while I was still adding in features.
Of course. Will try to get it running using the readme. If you have any problems let me know. I am on OS X myself so I should be able to make it work for you  Will try to keep my noob questions to a minimum...but have never dealt with QT before..is QT 5 ok or must be QT 4? Asking because I'm getting build errors..jsut trying on OS X for now..will try ubuntu as well. |

Hey Maxmint just a quick follow up since I don't think you read the development thread (often). Zathras pointed out that the actual Bitcoin payment also needs an output to Exodus. This means yesterday's trade is not actually valid. Just so you know why you might be down 1 test coin later today  Thanks for the note, I'll make another transaction later. Also, I'm closely following the dev thread now FYI maxmint - I went ahead and sent you the 0.1 test msc separately since you did pay me and its good practice for me to put the tools to use.. |

I saw that also but could not figure out how to sign the raw transaction. Would be nice if blockchain.info could also be used in addition to the console but I couldn't find a way to do it. |

I guess something is not quite right. My purchase of 0.2 Test MSC on 18xEZx3po1iJWP5H2aM3Do11dCGQyaebnT is not showing up at masterchest.info but does show up at mastercoin-explorer.comAlso, masterchest.info does not yet recognize tx c7103de53a8ea3a20cec9a74543132f98302f75ab1868092e911dd5516f322a5 (sorry if I'm pointing out the obvious Zathras) |

Good news! I will update my codebase and know that I can move forward in safety now Funny...I think I was in the middle of a transaction as you updated the codebase as I saw the previous purchases vanish from one moment to the next. I've completed a new order against my original sell and it went through just fine by adding the amount to Exodus. Let me know if anything looks odd. Will it be somehow possible to set up bids? Or can purchase offers only be made against existing sell offers? Just wondering if it would be usefull to setup multiple offers to create data points for anyone looking to develop a ticker with bid, ask, depth charts etc.. |

Maxmint - that looks like my sell offer--just haven't gotten around to completing the test purchase as work has been nuts. If you do happen to complete the purchase before reading this, I'll send back the btc.
Thanks, but no need to send back – it's just small amounts. Also, I wanna buy your shiny Test Mastercoins [/quote Haha- ok. We'll have the distinction of the first person to person exchange. I think we need to move this kind of discussion to a testing specific thread as I'm sure there will be much more and posting here might be to distracting. |

Yes, that is exactly it. It recognised your payment as a valid one and is now waiting for the payment from the address that send the Purchase Offer. You might need to lock your unspent outputs to make sure the payment comes from the right address. Also note that you need to pay in time, the time set out by the original Selling Offer. Hope this explains it a bit more. Thanks for the explanation. The timeout is specified in number of blocks, is that correct? And does Mastercoin-explorer mark an purchase offer invalid if it is not paid within the required timeframe? The timeout is indeed specified in the number of blocks. If all goes well it should indeed change the status to expired and flag it as invalid if you don't pay within the proper timeframe However this is not instant when a block if found but happens on a 15 minute interval, it might be a bit lagging. My first purchase offer expired, I definitely waited longer than 6 blocks. But I made another purchase offer and paid right after creating it, so the timeout should be no problem. However, it's marked as expired: http://mastercoin-explorer.com/transactions/ee77b1382633f8a5def69b444d319548b304ad93d8bb73505f7ff1c5755fac18What am I missing here?

I saw on grazcoins site, the buy and sells created so far show up as Unknown.

Sadly from what I could find out Blockchain.info doesn't let you sign raw transactions. So for now creating either a Selling/Purchase offer requires either a Mastercoin wallet or a way to sign a raw transaction.
Ah..that's what I was guessing also after digging around. I'll try with another instance/qt-client later - just think its kinda fun that way vs. same console. Thanks for clarifying the time limit. I guess I'm wondering what the effects of this could mean compared to traditional, centralized exchanges. It seems like it could make for some pretty interesting market scenarios (manipulations?) and trading strategies if one can keep an eye on expirations/completions of other trades and offers for a given currency/share. |

Accepting / Buying an offer is harder with Bitcoind since you need to lock all outputs that are not coming from the address you want to buy from.
So..I have some time to mess around a bit and trying to buy the test coins from my sell offer. Have some basic questions I hope you don't mind answering. I made a purchase offer and verified the transaction using mastercoin-explorer. I'm buying using an address at blockchain.info and sell is from qt wallet so I'm a bit unsure of how to apply the steps in this scenario. Is it possible to send an acceptance message using the tools available at blockchain.info? or are both parts of the transaction only possible currently with bitcoind/qt on either side? Also, when I set the sell, I put a time limit of 6 blocks. Can you explain the function of the time limit? Sorry if this was explained elsewhere and I missed it or its just simply common knowledge I lack - I want to make sure I'm not making wrong assumptions. |

I'm happy to report that the first distributed Mastercoin to Bitcoin transaction using the Mastercoin protocol has been done.
Congrats Tachikoma, this is just awesome! It's just incredible how fast this is evolving. Is the "Create new Selling offer" tool on your site already functional for public use? In theory, yes. I used this myself to create the transactions. It does require some knowledge of bitcoind/qt command-line though, I've written some instructions here if you want to give it a go. Also remember I'm only allowing test Mastercoin transactions. However the Bitcoin you are using to send the messages is always real so be careful you are not using high values for your offers if you decide to create one. Really cool Tachikoma - decided to give it a try. I was able to set up a sell offer no problem: mastercoin-explorer and blockchainReally gotta get some sleep so didn't actually try to buy them from myself. Also, I'm a little curious to see how expired offers are handled and represented. FYI - I noticed on your instruction page you indicate "broadcastrawtransaction" rather than "sendrawtransaction" which I'm guessing is what you meant. |

Awesome job Tachikoma! This is really exciting!
Can you modify the order book to distinguish test MSC transactions?

This is the transcript: According to Canadian media, the world's first Bitcoin ATM will be launched in Canada this week. With the hand scanner, users can exchange between Canadian Dollar and Bitcoin with the ATM. Before this, people could only exchange Bitcoin on the Internet. Bitcoin is a virtual currency. It can be used to buy goods on the Internet, and even pay house rent. Accodring to the latest market information, one bitcoin can exchange approximatly 1200 CNY If you like this news or the transcript, please consider to donate a few bitcents to the address below. We are seeing interest from China in the MasterCoin project as evidenced here: https://bitcointalk.org/index.php?topic=265488.msg3429668#msg3429668Maybe you could assist transcribing the mastercoin instructions into Chinese? |

Does anyone have guidance for setting up mastercoin advisor in Mac OS X and/or Ubuntu?
To answer my own question in case anyone else is interested and is pretty much a novice to this stuff as I am, yes, MasterCoin Advisor works perfectly fine in Mac OS X. As JR explained, running his tool requires python 2.7 and pycrypto. Python is native to Mac OS X. The easiest process I found to get things working in Mac OS X (Mavericks) is: 1. Download/install latest XCode 2. Download/install latest XCode command line tools (in my case, the latest version released in October 2013 for Mavericks) 3. Download/install paramiko https://pypi.python.org/pypi/paramiko/1.12.0 Install for this is easy - from directory you can type: sudo easy-install ./4. Download JR's MasterCoin advisor https://github.com/dacoinminster/MasterCoin-Adviser/blob/master/MasterCoinAdvisor.pyAnd that's pretty much it. Been wanting to test sending coins around and was getting stuck setting things up so was pretty excited once I got things going. So maybe this will help others. Sorry this is way too trivial for this thread and probably not the best place to post. I was going to put this in the buy/sell thread but that's been getting cluttered with other non-trade related discussion as is...maybe its time for a How to send MSC/Troubleshooting thread? |

Edit: Couldn't help myself and added the top 50 to Mastercoin-explorer. It might be a tad slow since it's not being cached and the lookup is very inefficient but it works for now. Yes, very cool Tachikoma, thanks! Would it be possible to also get a column showing each addresses percentage of all Mastercoins? You ask, I code. Refresh the page. 5 wallets (people?) control 60% of all Mastercoins. Still not seeing the percentages but I could tell from the values its pretty top heavy...the new 1 percenters? Will be interesting to watch how these distributions change once a proper exchange mechanism is put in place. |

Here is a CSV of each address and their balance. Seeing this overview I spotted a transaction that is being parsed wrong so that's worth something. Edit: Couldn't help myself and added the top 50 to Mastercoin-explorer. It might be a tad slow since it's not being cached and the lookup is very inefficient but it works for now. Very Cool! Thanks Tachikoma! Didn't realize the number of wallets with MSC was so low. |

Could be mine. Earlier this week I mistakenly used a web wallet for a transaction that was refunded to me. Though being a web wallet I didn't receive the refund. Total amount was .99 btc that got broken up into several pieces. Just decided to treat it like a ticket as well as a small gift to fellow bitcoiners. Makes me wonder how often this happens.
At any rate, if it was mine, enjoy!
