I was wondering if any of the ewallet providers have some form of dead man's switch. Let's say Bob has 200 BTC in an ewallet, and another 5000 offline somewhere. Could Bob set up a system so that, if he dropped dead, his wife or kids would get an email with detailed and fool-proof instructions as to how to retrieve both amounts?
The better question is, why do you not trust your wife enough to tell her NOW: honey, on this here piece of paper there is stored 5,000 bitcoins. Because Bob just wants his bitcoins to be divided among selected people after he dies, not share them with the person who happens to be his wife right now:) |

How do you solve getting to the secluded bitcoind to command it to sent bitcoins out? IMO, the best solution is to walk a request to the box. You can also have the box connect out to a web server that provides it with transfer requests that then just have to be manually approved at the box. The most common transaction will be to move coins to the cold wallet, so all you need is an amount.
The secluded server will have a payment processor that will access the production database from behind a firewall, verify transactions for fraud and send the payments out.
Polling another box? Connections allowed only from select IPs?
While nothing should be allowed to connect in to the wallet box, processes on the wallet box can still reach out to other boxes.
Thanks for the replies. I guess most newly incoming bitcoins can go straight to the cold wallet and have the exchange run on a manually updated hot wallet. It's more the hot wallet I'm trying to understand. It is needed for the exchange to instantly process transactions directed by customers. So there'll always be a kind of command path going from website to wallet, no matter how far away you hide the hot wallet, and we'll have to trust that path we setup ourselves. A good hacker will find that path and command the bitcoind. So there's actually no need to trust our path if we can't trust our website. Now, of course you can have the hot wallet pull for commands and transactions, but then.. how do you trust the content of those commands and transactions? Because, basically, that is that same public website with input from customers. If we can't trust the website giving commands into the hot wallet, [edited:]how can we trust that same website to collect and offer the hot wallet valid and intended commands to pull? |

The system was connected to from one of our other boxes which was accessed through a virtual console. The wallet box had all public ports blocked but was able to be connected to from a few of the other boxes.
Thanks for confirming. This is why I prefer no incoming connections allowed on the secure box. If you must have occasional ssh, you can have it enabled on boot and then login to disable it. That way you can reboot first if you must login. How do you solve getting to the secluded bitcoind to command it to sent bitcoins out? |

Are those Korean salarymen?
Chinese prisoners mining WOW gold while taking a break from their mundane Bitcoin Magazine duties. Seems they like spending time digging gold in WOW more than spending time on their Bitcoin Magazine duties:) |

Since the machine is obviously connected to the net, you could potentially be ordering and paying on your way to the machine. Just as you step up, the item is right inside that awesome door.
Or pre-order and reserve your item using your 'vendingmachine app' online or on your mobile, lock the buy with a one time pincode you decide on, pick it up when you want by entering that same pincode at the vending machine. |

on the subject of QR codes, you could just print a separate code above each item in the vending machine, then all a customer has to do is scan the code and push 'confirm' and the machine will vend whenever it receives a payment on the particular account.
Of course this means if you ever change prices you need to re-print codes with the correct payment value on it, but it does mean that no codes need to be entered into the machine at all.
I love that idea! Point your camera at the product, confirm payment, and you're done. Something like this has been done and very smart as well: http://www.youtube.com/watch?v=o9zcs1dg8qoBitcoin integration should be a breeze. |

Governed by math,
controlled by no-one,
freedom to spend.
I would make that Governed by math, Controlled by you, Spent in freedom or spent with privacy? but that's of lesser concern to people and less true because of transaction tracking |

Here is the word cloud from episode 1
That word cloud is awesome! It so reflects and attracts to the content. You should make these clouds links to every corresponding archive. And use the overall cloud on all episodes on your main page. Cheerfuller colors as well:) |

Regarding the live stream idea - This would be ideal, and Atlas and I have discussed it (he thinks we should do it as well) - I actually have been down that road before with one of my other shows a few years back, and it was a real nightmare logistically speaking. I'm not opposed to it, but I ain't gonna be the one working the technical side this time around, so the live stuff will have to wait until we can hire someone to do our technical backend for it (which is going to take a bit of work from you guys in terms of donations lol) But once we build up a little bit of a warchest there are several things we'd like to roll into.
If you'd like, I can hook you up with streaming. Been doing this for over 5 years. The only thing you'd have to do, is get your final audio output connected to some software that records your output and streams it to the server. Server has triggers on live stream starting and stopping which means you can auto-msn (and with some extra work, auto-twitter:-)) the start and stop of your broadcast if you want to. The connected stream is also recorded so when the stream stops, it's available for download/streaming as an archive instantly. Techie short specs: output mp3/ogg/theora into Icecast2. None of that future flash and silverlight shize, just plain direct links to streams themselves, usable on all OS platforms! Just PM me if interested to read more and see live working demo. |

Good show, way better then that Wegner guy.....sitting round with laptops and skyping chile is not production value!
Donation sent. Please, please, please do what you can to gather the scraps of valuable information together for your show so that when we hear it the topics are new and interesting. I'd also suggest you nab Bitcoin project seniors and give em a good talking to! :p
Good luck with the project guys.
I second that! |

How did the miner lose his bitcoins?
He was too busy with the dollars he saw!

Smooth!
Which font type did you use?
I like it.

If you could make a good site then why not sell stuff for USD? That is why my hopes are for a) remittances (shady/ hugely bloated / noncompetitive industry) b) poker (illegal in usd) c) drugs (illegal in USD) d) sexcam (paypal won't handle it and it could dramatically reduce the costs of entry for individual providers and cut out gouging middlemen)
For other commerce, bitcoin has wasted rewards on early adopters that could have been shared with adopting merchants (under alternative currency generation rules). On the plus side, further growth in the shady stuff could bootstrap future growth in the legitimate stuff.
I've been lurking this forum since February and the above words are like poetry to me! They so simply express what I've been thinking all these past months! |

Got 0.00* bitcoin at Mt.Gox.
Wonder if I can get it out. It wouldn't let me before.
The 0.00* got stuck while getting out all of my coins.
I guess it only pays out rounded to 0.xx

Folks, in the grown-up world, trades are unwound when the market malfunctions.
Kids, in the grown-up world, centralized currencies are used for trades. |
