You could also use a P2SH-style transaction, moving the data into the scriptSig:
Using P2SH at least means the unspent txout is small, and does not carry the extra data. |

This conference had essentially two strands: technical aspects and social aspects. This worked well, but it would be great to have business aspects as a third strand at future conferences.
+1 agreed... |

Is there currently a GUI that supports multisig? Is it a part of bitcoin-qt 0.7?
It is only RPC at this point. |

But even after that, there's a big hurdle for client developers, because signature collection is going to be a pain in the ass. That's why I created BIP 10 (and already use it for offline transactions), but it might need to be expanded or supplemented with more user-friendliness. Ugh... For the audience (I'm sure etotheipi already knows this) "pain in the ass" might be more specifically translated as: it is an Out Of Band problem. You definitely need to collect together the keys somehow. |

Maybe the "major announcement" will end up being Jeff's work on speeding up the initial download of the block chain.
Appreciate the thought but (a) I.B.D. speed-up was the work of many people, not just me, and (b) it has already been stated in this thread (or linked to, I forget) that the announce is not some technical software feature found in the Satoshi reference client. |

I'm sure uploading a video on youtube cost at least 100$
Probably far more than that, if you include obvious costs external to the youtube upload, like the videographer's time. |

We need someone recording every talk and quickly uploading it on youtube as it end.
Sounds like a great idea for next year: pay some bitcoins for this service, rather than complaining about not getting something for free. |

So... the fact that Gavin was invited to give a talk to the CIA over a year ago didn't mean Bitcoin was already on their radar?
CIA != Fed I know a lot of people see "the government" and instantly assume that a presentation at government office A will instantly result in the entire federal workforce becoming aware of said presentation's contents, but that's not how real life works  In 2010, the federal government workforce numbered at 4.4 million people. And most of those are hunkered down in their little slice of government, not talking to other branches. |

Thanks Jeff!! Any change we see the actual recording of the talk? The conference organizers recorded all the talks, and hopefully will have them up on youtube $Sometime. |
|

All the talks were recorded, and should be posted $Somewhere, $Sometime.

sipa's presentation at Bitcoin Conference 2012 including some information, because his "ultraprune" branch slated for 0.8 will specifically index unspent txout's. Not quite the information you wanted, but it is worth a look for you.

This is sadly already common in the poker world, HYIP forums, etc. It was only a matter of time  I think somebody has already tried DDoS+ransom on MtGox, a while ago, IIUC. |

But, as a percentage of total transactions using each currency, Bitcoin illicit goods trading takes the cake.
Evidence, to back up this hand-waving? |

Bitcoin companies that are large enough to end up in the crosshairs of regulators need to comply with all the rules which make Bitcoin necessary in the first place or else risk being shut down.
Indeed. It's a temporary problem that will go away when most people get their bitcoins via trade instead of buying them on an exchange and spend them instead of selling them for other currencies.
Yep, do something productive and get paid in bitcoins. That is how the bitcoin economy is built. |

Seriously? One name that's something in bitcoin, say it. Who's there?
Even if you disregard Nefario (GLBSE) and Intersango (libbitcoin), there's Tony Gallippi from BitPay, the guy from Butterfly Labs, Stefan Thomas (bitcoin-js), Pieter Wuille (core dev team), Jan Moller (BitcoinSpinner), Jim Burton (MultiBit), Vladimir (Bitcoin Magazine), Juraj Bednar (he's been promoting Bitcoin in Slovakia), the guys from Bitcoin Austria, and tons of people I didn't have time to meet or whose names I forgot. Of the core dev team there's myself and Pieter (sipa), and I think Nils (tcatm) is coming too. |

When I query the daemon, I expected it to use an IPv6 connection however the system shows that an IPv4 connection is used to query the daemon. Using "bitcoind -onlynet=IPv6 getpeerinfo" makes no difference, the communication is still using IPv4. How can I use the client to query the daemon using IPv6?
hmmm, I think the HTTP client internal to bitcoin did not get updated to make IPv6 connections. Worth filing an issue at github. |

Custom binary protocol using Google Protocol Buffers would be much preferred. You write Protocol buffers by Google is interesting concept which may fit the needs, except that only C++, Python and Java are supported.
Your list of supported languages is woefully incomplete, and therefore, does not support the argument. PB are supported for: C, C++, Python, Perl, Java, PHP, Ruby, and Haskell at a minimum. Any language used by the bitcoin community is highly likely to be supported by PB. Furthermore, PB encoding is strict and well debugged, unlike any newly created protocol (including my own binary protocol from years ago) and this new protocol. Something for ASIC miners should be bandwidth and CPU efficient, and text/JSON is not that. This has already been shown to be a problem in bitcoind, where pool server operators replaced the default JSON hex decoding routines with a faster routine, to decrease CPU usage associated with useless text encode/decode. PB is used in thousands of apps, including most of the Google applications we all use (like search). |

Pretty much everybody on the speakers list will be there, at least, including me About to board my BOS->London flight right now... |

well, the documentation seems to suggest that you must enable ipv6 by including USE_IPV6=1, but the build file has USE_IPV6:=1 as default. i tried changing that to USE_IPV6=- and USE_IPV6=0, still results in same error
Try commenting out the entire line |
