Use this Python code:
$ python
>>> "%x" % int("".join([str(int(c) - 1) for c in "6132235463233123456522124112542554365223124562346652123111266"]), 6)
Replace the string "613...." with whatever you want. I'm assuming that each digit represents a dice roll from 1 to 6.

https://github.com/darkwallet/python-obelisk/See examples/ directory. This is a collaboration between Pablo Martin's ZMQ/Obelisk implementation, and Robert Williamson's blockalchemy library with code from ThomasV's Electrum. Obelisk is a scalable blockchain query infrastructure. See the setup guide. There is a public server available at 37.139.11.99:9091 but I wouldn't use it for anything production (besides testing). A pure Python library is great because it can be deployed easily without requiring dependencies. This allows code to be ported across many platforms such as the mobile phone with Kivy, desktops or any platform running Python. Features: * Blockchain queries and navigation through Obelisk servers. * Construct & sign transactions. * BIP32 hierarchical wallet. * Traverse the blockchain using a syntax similar to Django ORM / SQL alchemy. Use cases: * Website payment backend (store and manage the keys yourself). * Wallet software.

Ah man I was an early adopter but I spent now millions worth of BTC already. Was having trouble even affording socks this summer. But had lots of fun along the way and there's more cool stuff to do. Bitcoin is not even 1% yet of its potential.

oh this is wicked! this is exactly what I wanted! can I include them in the project?

Just got sx built under Ubuntu, thanks! Just wondering how portable 'sx' is to windows? Do I need cygwin, or is it possible to compile with VC++? Any build instructions anywhere (or pre-built binaries)?
never done it, but when our infrastructure is more setup (after crowd funding) we will be deploying/testing/making builds. |

Sorry about your dog. I'm powerless to help here. If it's any consolation, I spent this summer going through a lot of hardship like cold and sickness due to lack of money. Patrick has no reason to steal and he's not like that.

hey, that email is just a bunch of whining. I reimplemented Bitcoin because all the internal parts are highly connected. Your validation code is linked to blockchain, network and script subsystems. It was a purely technical decision. In the beginning (early 2011) I started by refactoring the Satoshi codebase (made Python bindings and improvements in a custom fork) but the entire thing is total crap and tightly coupled. I decided if Bitcoin is the future then we need a solid foundation to build upon. Rewriting Bitcoin from scratch by comparison is not a big deal in the long perspective.
his complaint is invalid. satoshi is not a god. we write code, improve the software and move forwards. Bitcoin is not some mythical codebase.
The blockchain is bigger since it is optimised for servers. I'm thinking primarily about scalability then performance. bootstrap.dat is supported thanks to Robert Williamson. I'm working on supporting luke-jr's eloipool but a lot of the mining stuff is new to me and I'm preoccupied with dark wallet this month.

The script subsystem only requires the tx you are signing.
The point is more succinct - avoid extending the Bitcoin standard.
I would also like a SIGHASH flag where you can specify a specific output to sign (so you can specify change address with pledges for SIGHASH_ANYONECANPAY), but I don't think it's a good idea to change Bitcoin's current design. More dependencies and execution paths = poor design = insecure code. We should be taking things out, not putting in.

But I don't find them malicious, just incompetent.
... corrupt lovers of power and control freaks. That has not been my experience. I'm sure that many elected officials have that mindset, but my family members in the FBI for example are more like boyscouts. They want to do good. Sometimes it does not work out though. Take the disastrous drug war. Which has caused so much suffering. I approach such problems with engagement. And I see it working in places like Colorado and Washington state. Don't fight the government, make it do your bidding. I've had many many experiences with police. 80% are just doing a job to pay rent (so was Hitler's SS) and 20% love their job, going way beyond the call of duty to enforce laws and get at 'bad types' they don't like (sometimes bending or breaking the law). They break into houses, arrest people for assault, beat people up (off camera), follow and harass you, ... they are not all good people and I don't support their work which is mostly being a pawn of powerful interests that collaborate with wealthy groups to fuck you. Here's 3 PRISM slides from the NSA:    I don't know what more kind of proof people need that the police are corrupt, and we don't need to help make their work easier with applying law to bitcoin (in their own interpreted way). you know the blacklist in the UK which was originally only for child porn and now blocks 'hate speech', copyright infringement, 'bad porn' and the pirate bay was originally formed as a consensus amongst ISPs after the metropolitan police put pressure on Demon internet. the same steps are now happening with bitcoin and it's looking semi-legit with people justifying it. but even a cursory look at internet history will show you what the slippery slope this is and we must fight hard against this tooth and nail. not later, but now. now is the time to fight for your freedom, not later once everything is compromised. |

You guy really need to read the senate testimony. Not one law enforcement agency or regulator blamed bitcoin the protocol for anything.
...
knuckleheads...
did you see the task force? http://www.wired.co.uk/news/archive/2013-09/13/digital-economy-task-forceThe Task Force, which launched in August, is not solely focussed on child exploitation. It has developed working groups that aim to combat a range of illicit activities, to safeguard human rights and to encourage inter-agency coordination and law enforcement. The report detailed how criminal and terrorist organisations have turned to digital currency to reap profits from drug trafficking, prostitution and the dissemination of child abuse images.
Steve Rubley, managing director, Government Segment for the Legal business of Thomson Reuters points out that the digital economy provides a plethora of new opportunities and is central to how business is conducted but there are also "dark corners" where drug cartels can easily launder money and human sex traffickers operate in near obscurity. this is pandering in the hope of being spared from harsh treatment. nothing good will come of this. bitcoin is what it is: world changing technology. the printing press fundamentally altered old power structures against their will. so too will bitcoin. we haven't even begun to explore the possibilities it brings. we don't need to ask permission. the market is here and won't be stopped. we need to be bold and brazen in how we nurture this early and exciting technology. it is a tool of the black market. it will transform humanity for the better. government education begins and ends with those statements - nothing more. we don't need anything the legacy system has to offer. sooner or later, the people will come around as the pull of bitcoin will be too strong. from the ashes of a corrupted system rises a bold new paradigm for global humanity. |

This is fantastic news. I was expecting it for a long time, actually at the Amsterdam conference last week I was talking to a member of the Dutch police who had taken part in a panel, and mentioned I was waiting for DPR to show up in a US court at some point. I didn't think it'd happen a week later, but this outcome was eventually inevitable.
The point I made to Niels (the police guy) was that DPR had way too much confidence in the technologies he was using to keep him safe. I said I understood Tor and Bitcoin very well and there's no way I'd treat either of them as a silver bullet. And that's assuming NO mistakes. I didn't even know how I'd cash out. The best some people listening in could offer was "find someone who would help you cash out that's not an exchange". But where would you find someone capable of sinking non-trivial amounts of Bitcoins for dollars, outside of an exchange?
It's hard to tell from the documents to what extent he cashed out. Perhaps those details will come at trial. But given he was living with flat mates I guess his lifestyle was cheap and he probably didn't ever cash out into dollars in a big way - obviously lacking any fake IDs he didn't have any way to use the exchanges. This is also very good news. It is a strong argument that Bitcoin is not some super trivial way for criminals to make wild profits - despite the huge sums being quoted by the FBI agent, those are theoretical amounts of dollars he could have obtained if he'd had some way to do so, not amounts he actually made (given the tiny size of the Bitcoin economy).
By the way - I'm amazed at how many people are surprised that a drug dealer with extreme anarcho-capitalist tendencies turned out to be not a swell guy! Imagine that!
mike, your bitcoin users are silk road users. why are you helping the police? they don't use bitcoin. are you going to quit your job at google now it's public they are collaborating with the NSA. or does google pay too well? how much is the NSA offering bitcoin developers? behind closed doors we don't know what's happening and who at which corporation is now being tasked to write code against bitcoin users to protect their business interests or even with a hefty salary from law enforcement themselves. |

I've worked with Animazing before on Electrum and he's a solid developer you want in your community.

Sorry but I don't think this is worth hard forking Bitcoin over. For validating a signature we currently need only the input (if it's signed). This change increases the number of dependencies for signature checking code. Namely Bitcoin validation nodes now need to fetch the previous output. This could seriously complicate the design and functionality of Bitcoin nodes if widely used. It is a good idea, but there are many ways to improve Bitcoin. I'm not sure Bitcoin is made for these things and should stay more simple and focused (like UNIX vs the other operating systems). http://www.gwern.net/Bitcoin%20is%20Worse%20is%20Better?2Bitcoin works because it doesn't try to do much. If we want to maintain a decentralised and open Bitcoin, I think it's a bit of a slippery slope to throw every feature we get excited about into Bitcoin. |

The risk is bigger than you realise. It isn't even overt mailicious features that don't require changes to Bitcoin itself, but small corruption of Bitcoin in deep underlying hard-to-perceive ways. It's not only bugs but the values of the programmers and how they mold the software. For instance there are deep issues in the protocol where the decision is not always clear (and the community is ignorant of them). If you work for a corporation, your choices are going to be different to the guy running black markets and doing p2p trades. You just both value different feature sets and the software optimised in a different way. From this article: https://letstalkbitcoin.com/the-regulation-of-bitcoin/"If development is too centralized, with a small core infrastructure, then businesses will put real pressure to have features that destroy the integrity of the Bitcoin network. The excuse will be to protect themselves from liability. Self-censorship.
And what they demand does not have to be protocol changes. They will demand features in the software they use. Software which remains compatible with the network, but works against the interests of individuals, small businesses and the black market.
The possible malicious scenarios are endless. Stuff like p2p blacklists to create a ‘legitimate’ walled garden, or tracking technologies like large databases of IP addresses to triangulate where transactions came from. At the other end of the spectrum, is putting development effort into diversifying the ecosystem to protect against censorship and proxy relay nodes, anonymizing mixers, small privacy tweaks and other technologies. That’s where developers who believe in Bitcoin should devote time to. Corporations are powerful enough. To developers: serve your community." Blacklists from both the merchant and the miner (prefer to build off blocks with txs containing whitelisted addresses) will push Bitcoin users towards monitoring. We need a strong hard push against this stuff right now. We need to be vocal and build tools for black markets. Pretending we are friends of the NSA is not helping our cause. |

This is a really cool project and I think you can go either further.

I would like if we're altogether to organise an assembly for discussion of these ideas.
