When M-Pesa integrated Bitcoin payments through Kipochi, there was a lot of hype about the effect Bitcoin going to have on the African remittance sector. But unfortunately, the service died down only a few months after it started.
Kipochi as a service was a failure but the idea of a SMS network being developed in Africa like 37coins piqued my interest |

A hard fork is a change of the Bitcoin protocol that is not backwards-compatible; The example from 2012 your mentioning is from March 2013 and was a Chain Fork which resulted in a new client that did not recognize previous Bitcoin transactions An explanation of what happened is in this link https://bitcoin.org/en/alert/2013-03-11-chain-forkSimply put the reason for reverting back was that the new client was not compatible with the old one so the community decided to revert to the original chain and abandon that fork. http://bitcoin.stackexchange.com/questions/9986/how-is-a-hard-fork-resolvedTo simplify it a bit more Miners control the network and can decide on any changes to it with the majority of mining power Edit Found a Reddit think this is simple enough if your still a bit lost feel free to ask http://www.reddit.com/r/Bitcoin/comments/1a51xx/now_that_its_over_the_blockchain_fork_explained/The programs that read the blockchain, the bitcoin ledger, disagree. Due to a bug in 0.7, it says that HIS is the correct version of this ledger and 0.8 says that HIS is the correct version. Miners (the people who add pages to the blockchain) are told to switch to the 0.7 program so that this version gains more support and the other one is discarded. (orphaned). Regular users are not affected. Their transactions are included in both ledgers and don't need to change any programs. During that time, though, there is a slight chance of a double-spend ocurring. That is why people recommended merchants and exchanges to wait until there is one single blockchain again before processing purchases and merchandise. @ In regards to op there would be two ledgers recording transactions at the same time Both would disagree and state their version is correct and miners would make the final decision The network does not shut down it's just that their are two chains recording the transactions and not willing to agree with each other on the outcome This is resolved with one chain becoming longer than the other The problem with the 2013 fork was that 0.8 and 0.7 both thought their version was correct and could not resolve the issue This was solved with miners deciding to use 0.7 over 0.8 which then led to 0.8 accepting the changes and not disputing the transactions. |

Well the US was expecting the private ventures to make them space capable by now
The problem with killing the shuttle program is that they didn't adopt the capsule program
Proving that the Russians were right that a capsule is better than the reusable shuttle in terms of cost at least but not size.

Reeds rings a bell with me now I know why
Glad to hear they are also taking Bitcoin and now I can get bling with BTC
The large and well-known jewelry store chain has teamed up with Coinbase to allow for bitcoin acceptance both on their online store and all 64 retails locations sprinkled throughout the United States.
Customers will be able to purchase gold ingots and fine jewelry and watched using the digital currency, complete with GIA grading reports, according to today’s announcement.

The fact that they hit 48% tells me the average miner doesn't much care about it.
Because it's a non-issue. And if it becomes an issue, they will obviously move, as their profits rely on the success of bitcoin. Well I think this opinion might be partially correct that said I read a few threads on Gigahash abusing its power when it last had greater than 50% of the network by reversing bets. That said the network should correct itself if it is abused again so a non-issue but with a caution involved in it. That said there is more incentive to leave the system working as it is than to double spend on it and lose more than you would gain |

Fair point Byrant, I just went with those two since they are the typical ones on the table when your talking about the NPT and Non-Proliferation.
Non-Proliferation of Nuclear Weapons must mean that none of the world nations can possess nuclear weapons. It is hypocrisy from the part of Russia and the US, when they say that other nations can't have nukes and only they can have them. It is hypocritical that is why the NPT has had a resolution for them to denuclearize their own arsenals every 5 years Which the US and Russia did by decreasing total units but also updating and modernizing their arsenals That said the NPT is non binding and attempts to make it binding would result in states leaving the treaty so its complex. Pretty much can sum it up here http://www.armscontrol.org/act/2013_12/How-Divergent-Views-on-Nuclear-Disarmament-Threaten-the-NPTConsequently, nuclear-weapon states consider nuclear disarmament and the achievement of a world without nuclear weapons to be a long-term aspirational objective at best. Thus, pending the achievement of perceived global preconditions for nuclear disarmament, these countries are prepared to take only limited and gradual disarmament steps without fundamentally reassessing the role of nuclear weapons or altering the nuclear strategic balance. At the same time, nuclear-weapon states focus on the prevention of further proliferation of nuclear weapons, which they see as the only real challenge to the integrity of the NPT. This is not only their clear priority, but they argue it is a necessary precondition for more-substantial nuclear disarmament steps. The perspectives of most non-nuclear-weapon states regarding the urgency of nuclear disarmament are quite different. Among these countries, nuclear weapons and nuclear deterrence are widely seen as a high-risk approach to national and international security. According to this view, humanity escaped unharmed during the Cold War period and thereafter as much by luck as by design. Moreover, the concepts of nuclear deterrence and the necessity of nuclear strategic stability, which were merely transferred to the 21st century with little change, look increasingly anachronistic 20 years after the end of the Cold War. This lack of adaptation to new realities might be seen not only as a missed opportunity but also as a serious misjudgment and a key driver and incentive for proliferation. Arguably, there is a direct relation between the continued reliance on nuclear weapons by nuclear-weapon states and the quest for these weapons by other states. This link can only be broken by a collective and sincere move away from nuclear weapons. Most non-nuclear-weapon states that are not part of “nuclear sharing arrangements” or “nuclear umbrellas” consider nuclear weapons to be highly dangerous in themselves. They view retention of and reliance on nuclear weapons as outdated, while seeing disarmament as an essential element of preventing the proliferation of nuclear weapons. The mere existence of nuclear weapons results in a permanent risk of devastating consequences for the entire planet. Such an existential threat to all humankind should no longer be handled by a few states as a national security matter to the detriment of the security interests of the vast majority of states. So it's a fundamental shift in the approach between the Nuclear Weapon States and the Non Nuclear Weapon States on Non-Proliferation |

yeah finally i am confirmed by XBTec with bitcoininformation hold his escrow, everything will be fine;D i have bad experience with updown.bt before  I think OP should remove BTCX2 campaign in his list since they are PONZI operator with their link listed in OP post, did we facilitate people to support ponzi indirectly ? Well the forum allows it and this is meant to be a comprehensive list of all signature campaigns So picking and choosing doesn't make sense to me Rather a warning or an * before a signature campaign or a Joining is not Recommended measure seems like a strong enough action to me and to let the users decide if they want to join that campaign or not. |

The problem is not all nations are transparent about their facilities and capabilities
Having enriched uranium for medical usage (nuclear medicine) requires 20% purity
That said once at 20% it becomes much easier to get to 90% nuclear grade than it is from that 3% to 5% enrichment
No need to single out North Korea or Iran, when none of the nuclear powers themselves (including India and Pakistan) are transparent about their facilities and capabilities. How can the US or Russia blame the DPRK, when the former is having thousands of nuclear weapons compared to the few dozen under the control of the latter? Fair point Byrant, I just went with those two since they are the typical ones on the table when your talking about the NPT and Non-Proliferation. Technical list is India, Israel, Pakistan, North Korea, Iran and Previously Libya to complete that list http://en.wikipedia.org/wiki/Treaty_on_the_Non-Proliferation_of_Nuclear_WeaponsI could go on a rant about how Israel's policy of ambiguity is a problem since they don't officially say we have nukes but also don't say we do not have nukes as well. Or India having Nukes making Pakistan want to have nukes as well due to their tensions to have a power balance but that said I agree with you having the nuclear chip on the bargaining table is a weapon that larger states simply do not want little or unstable states to be able to wield. Heck could even say Gaddafi following the USA and disarming his nuclear arsenal led to his downfall as without the nuclear deterrent they were not afraid to invade and take over the country Disarmament in 2003 http://en.wikipedia.org/wiki/Disarmament_of_LibyaInvasion and Takeover in 2011 with a civil war ongoing to now because even though Gaddafi was controversial he was the balancing pin between all different ethnic groups. Carrying on one DPRK missile launched would destroy a big area of Japan or South Korea and do massive damage (Not China though lone buddy/sort of), but that attack would be suicidal and that is what scares large states that one missile can be a giant threat and as a result slows nuclear proliferation even for peaceful purposes, since they assume not all actors are rational. Or governments change why South Africa abandoned its program once Apartheid failed and the ANC was to come into power. That said Solar is a neat solution to those energy problems just not scalable or low enough in cost yet (even with the recent US Solar Bankruptcies to Chinese Firms), but Geothermal seems like the most efficient one in the long run if technologies can improve stored energy forever (well a long time) from the Earth. However there is always room for a more diverse set of energy options but that Geopolitics still gets in the way. |

I am a bit jealous of the earliest adopters but they took the risk so they get the biggest reward This just goes to show that people of all ages strike it rich Just hope that is also myself in 5 years with Bitcoin  But 1000 to 100,000 must have sold around the 90 to 250 dollar range Still it is neat to see he has enough to pay his employees in Bits and launch his company Thanks for sharing this |

Thanks for sharing the full article I liked his opinion it does take time to develop an understanding of Bitcoin but once you do there is no reason not to believe in its potential.
It was the best performing asset of 2014 has a market potential far larger than Tesla and is in itself an innovating development let alone all the utility it can provide.
Simple but forward it is making money better by improving it let the bears join the bulls.

5 years from now people will be saying: You remember 5 years ago in 2014 you could buy 1000 bits/1 mBTC for less than a dollar, I wish I had bought a couple mBTC's back then, I'd be rich now!
Or maybe by then the dollar has already collapsed
I decided when I got into bit coin this past March that in 5 more years I would not be one of the people having to say that again. I m still slowly but surely collecting them and plan to be envied rather than feel envy. That makes sense there is a lot of money going into Bitcoin and the ultra rich and technologically proficient people are already launching several companies into this industry so I can see where this logic comes from. Also want to be one of those that has no regrets about getting a few mbtcs now and not regretting it in 5 years time. |

The biggest risk is that governments are concerned some of the byproducts from the reactors are then moved and converted into nuclear weaponry
The nuclear waste or the nuclear fuel can't be directly converted to nuclear weaponry. The Uranium fuel used in nuclear reactors is Low-enriched uranium (LEU), which contains 3% to 5% U-235. (The remainder is U-238, which is not radio-active). For creating nuclear weapons, you need Highly enriched uranium (HEU), which contains 80% to 90% U-235. Converting the LEU to HEU is a very complicated process, and only a very few nations in the world currently possess that technology. The problem is not all nations are transparent about their facilities and capabilities Having enriched uranium for medical usage (nuclear medicine) requires 20% purity That said once at 20% it becomes much easier to get to 90% nuclear grade than it is from that 3% to 5% enrichment That is why governments are concerned with Breakout which is the ability to get to weapons grade rapidly before any counter response can be done simply put the centrifuges just need 3 months from 20% http://www.iranwatch.org/our-publications/articles-reports/irans-nuclear-timetable___ Increasing the percentage of U-235 becomes progressively easier, as explained in a 2012 glossary by the Washington Institute for Near East Policy and Harvard Kennedy School. If the aim is to reach 90 per cent, getting to 3.5 per cent requires some 75 per cent of the work, and once 20 per cent is attained, nine-tenths of the job is done. For this reason, when in February 2010 Iran began enriching to 20 per cent alarm bells rang. This dramatically shortens the time needed – in theory – to produce a bomb's worth of weapons-grade uranium. Iran could, in theory, produce weapons-grade uranium from its stockpile of uranium enriched to five per cent using its existing enrichment facilities at Natanz and Fordo. But it would take considerably longer than with 20-per cent and crucially, the International Atomic Energy Agency, the UN watchdog, would notice any such "break out" long before it is completed. __ http://www.telegraph.co.uk/news/worldnews/middleeast/iran/10436068/Iran-nuclear-talks-what-you-need-to-know-about-uranium-enrichment.htmlNewer reactors have less of this risk but older reactors even CANDU can enrich to that level easily Take the Chalk River Facility the North American Source for Radioactive Isotopes it enriches to 20% and no one is concerned but if you put one of those in Latin America some people would worry about the facilities security from Terrorist Attacks and the risk they move to weapons grade weaponry depending on the transparency they provide. The reason their are inspectors checking those facilities or negotiating at the NPT every 5 years (Non-Proliferation Treaty) As an aside that does not mean sanctions on innocent civilians and student bank accounts is the solution either in regards to Iran. Economic warfare is still warfare |

nevermind the cost, it's human life that gets fucked over from the radiation poisoning. the more nuclear reactors you have, the more likely it's going to explode in your face. in the past 35 years, we've had at least 2 of them.. and almost a case in philadelphia as well.
and if you have a population that has been exposed to the radiation, you'd need to quarantine them.. otherwise they'd mix genes with other people and make babies with 3rd eyes.
The Chernobyl disaster was caused by the security lapses on the part of the Soviet authorities. But now the technology has advanced and there are no chances of any such disasters occurring again. There are hundreds, if not thousands of nuclear reactors operating across the world, and every year they save the lives of hundreds of thousands of people, who would have other wise died due to respiratory illnesses caused by the thermal power plants. The biggest risk is that governments are concerned some of the byproducts from the reactors are then moved and converted into nuclear weaponry Also how to dispose of nuclear waste Glassification processes etc how long it takes for spent fuel to cool down example Fukushima reactors Although countries like Japan have the tech and could go nuclear or China which is nuclear there are concerns about giving it to other countries Iran nuclear program/ sanctions and poor economic well being of its citizens as a consequence North Korea Nuclear Armed and Independent but based on the reports we have sucks to live there No New Nuclear Reactor has been built in the USA since 1977 because of increasing costs as more and more safeguards are put on them and people protest the idea. The only reason nuclear has been able to maintain its share of the energy grid is because of efficiencies found in reactors From 30% efficient in the 1970s to 90% efficient in 2000 http://www.world-nuclear.org/info/Country-Profiles/Countries-T-Z/USA--Nuclear-Power/That said until the Geopolitics is solved nuclear probably won't sell well for some time yet. |

The man with 1 billion bitcoin
It was Wednesday afternoon and bitcoin just rose to $1 when the man decided to take a walk to the park.

Try to do a mosaic of the QR code of your bitcoin address, it will take days to complete but maybe someone will reward you...  That would be something, never heard of a working mosiac QR code I know that you can get them in large corn gardens to work though So it would be neat |

Well actually I guess if you get food poisoning you shouldn't blame the Yelp users but look at the Kitchen of those restaurants
Anyways guess it serves as a warning be careful of what you eat

Thinking five years from now I expect to see this in every store in the world and bitcointalk being a busy forum talking about technology and general stuff.
Kind of curious though what the forums will be like 5 years from now
Reddit Facebook Twitter Style or 4chan
Best case a Github
