The article says: " Mazières’s new cryptocurrency protocol, called SCP, is being adopted by a nonprofit called Stellar to replace a Bitcoin-inspired system meant to make financial services cheaper and more widely accessible in the developing world (see “Bitcoin-Inspired Digital Currency to Power Mobile Savings App”)."
How can they think to replace bitcoin? I think they are only joking. SCP = Stellar Consensus Protocol Stellar team paid Mazières’s as a consultant for his contributions to the project. Edit: Spelling |

Great idea, can't wait to see how this plays out. I think we all need to consider using Bitcoin/Blockchain to replace/improve existing infrastructure. I created some similar software using Django about a month back, not centered around Message Boards/Forums but it utilized a similar idea that if a person is holding Bitcoin it can help provide some 'guarantees' that the likely hood of something happening is higher.

all good things must come to an end
my only advice to josh is don't pickup the soap
(come to think of it better if you pick it up because i have this strange feeling that you will enjoy it.)
Stop posting Altcoin junk in the Bitcoin general discussion. Paycoin is and was and has always been just a generic clone coin. People have been losing Bitcoin to Altchains for along time now, nothing new here. |

Hello,
I was wondering if there is any way for me to create a private key using only my fingerprint and a password. Do you guys know if there is already a website to do so ?
Thanks.
That is a pretty cool idea, I have not heard of anyone doing this yet. The biggest thing is how much Entropy a Fingerprint actually has. Some quick research shows that it should be possible to generate a series of numbers from a fingerprint 'reproducibly'. If you set a specific % matching thresholds 'noise' in the software capturing the fingerprint, lowering the threshold to generate a number from a fingerprint does reduce the amount of entropy available. Some estimates 40 - 80 Bits of Entropy. Kind of a wide range, but should still be large enough source for private key generation. Here is some information posted a year ago by someone that is relevant: http://www.reddit.com/r/crypto/comments/1fpobr/how_many_bits_of_security_in_a_fingerprint_as_in/Enhancing security and privacy in biometrics-based authentication systems - http://www.cedar.buffalo.edu/~govind/CSE717/papers/CancelableBiometrics.pdfHow to Generate Strong Keys from Biometrics and Other Noisy Data - http://www.cs.bu.edu/~reyzin/fuzzy.htmlEdit: Fixed Spelling |

I have my coins in cold storage with addresses generated using bitaddress.org offline. I have AES encrypted digital copies of the key pairs and kept them on usb sticks using gpg. The private keys have never been on an internet enabled machine.
I am interested in purchasing a metal cold storage wallet for long term physical storage of my coins securely. I am worried about leaving the data on usb devices over many years in case it degrades.
Something which has caught my eye which is metal bitcoin wallets which are nigh on indestructible. They seem to use BIP38, which encrypts the private key with a passphrase and returns a 6P address and QR code which can be swept easily into modern wallet software once decrypted. This seems an elegant solution and cooler than a usb stick and messing around with gpg on a linux offline laptop.
My question is how can I get a BIP 38 encrypted private key from a private key I have generated using dice or a mycelium entropy?
Obviously as this is for cold storage funds it must be secure..
Thanks
EDIT: i would have thought this was possible with bitaddress.org but although i can enter dice rolls and keys into it, it wants to generate new key pairs before it applies the BIP38 encryption.
https://github.com/bitcoin/bips/blob/master/bip-0038.mediawiki - Here is the actual BIP it has alot of great information. You could try using this JS Library: http://cryptocoinjs.com/modules/currency/bip38/var Bip38 = require('bip38');
var privateKeyWif = '5KN7MzqK5wt2TP1fQCYyHBtDrXdJuXbUzm4A9rKAteGu3Qi5CVR'; //Your Private Key generated from Dicerolls
var bip38 = new Bip38();
var encrypted = bip38.encrypt(privateKeyWif, 'TestingOneTwoThree', "1Jq6MksXQVWzrznvZzxkV6oY57oWXD9TXB");
console.log(encrypted); // => 6PRVWUbkzzsbcVac2qwfssoUJAN1Xhrg6bNk8J7Nzm5H7kxEbn2Nh2ZoGg

I saw that Braintree Bitcoin bilboard, SF certainly does have a number of places that accept BTC. (Not quite enough to randomly walk around and find them) Was this basically what you saw: https://pbs.twimg.com/media/CBdk1zAUsAEllD9.jpg:largeI think their are two or three of these located throughout SF. I know their was one on Lombard Street for a few months. A number of the food Trucks around Market District also accept Bitcoin. I haven't been down to LA or San Diego this year, but I imagine they are probably further behind SF in regards to adoption. I get a strong feeling that SF is quickly becoming the first/official Bitcoin hotspot. Almost every reputable Bitcoin Startup hiring is looking for people in SF. Kinda funny but I was having lunch about 4 Months ago and saw Gavin + several other Bitcoiners stop in for a bite to eat. |

I'll bite, bored at work a little bit. I am as we speak generating word lists for the 4 Character key, lets see how long it takes to even generate all the keys (16 Core Machine). I haven't setup an automated way to Decrypt the key with my word-list yet, so I might just donate the list with the key when it finishes being generated. Started Generating the word list at 10:45 am Edit: Added timestamp |

I call this FUD The OP, and the person posting to twitter need to invest more time researching the Network. I doubt they have spent hundreds of hours reading material, watching videos, and writing computer code to interact with the Network in any shape or form, to develop original abstract thoughts on the technology and how it can play out in our society. However they are certainly quick to inform others on their baseless uninformed opinion. I have always wondered why people are so quick to accept the given 'truth'. Sounds like someone who likes watching television and blindly accepts what they hear as factual. Bitcoin's fundamental solution is going nowhere, it will only be improved and matured as we have seen over the past 5 years. FUD  |

ESPN.com's Brett McMurphy reported on Wednesday night that Bitcoin was dropping out of its sponsorship deal with the bowl in St. Petersburg, Florida after only one year.

I've heard that the CEO of Bitcoin is a real bad ass - http://media.giphy.com/media/zqhZB6bo5FgoE/giphy.gif - (Hank Scorpio from Simpsons GIF) Seriously, I don't really think Sports were a good venue for a Bitpay sponsorship. It would be been much more ideal for them to sponsor some e-sporting event. |

This is actually pretty cool, I remember seeing Attitude Seeds Advertisements in older Hightimes Magazines, they have been around for years. If I recall correctly purchasing Cannabis seeds is legal in most countries? As long as you never intend on germinating them? I might be wrong  Edit: Grammar |

Hey all,
Wondering if any of you know some good Bitcoin YouTube vids that are about an hour long to show at an office lunch and learn. It shouldn't be too technical but should also show what the power of the blockchain is capable of.
Could be a panel discussion, interview, etc.
Any ideas?
Thanks!
Here is a recent 15 minute video I think is pretty insightful, it was a presentation entitled 'Bitcoin: The new Gold Standard', presented by Xapo's Wences Casares. It does not drill down into much detail. But it should give a good over view of what problem Bitcoin is solving, how money/ledgers have been used in history. https://www.youtube.com/watch?v=yPIvqJsCOSoWinklevoss brothers made a decent presentation that is pretty high level 'business oriented' - http://www.slideshare.net/winklevosscap/the-internet-of-moneyTheir exist tons of good materials, above are two I can think of that seem to be a bit less technical but get across good information regarding the technology.

Let's cut the crap. Most of us are just waiting for Bitcoin to finally hit $100 to buy a huge quantity. Am I right or talking out my ass?
Probably going to wait for a lower price than 100, I really think it can fall much further. I have been researching on what % of the currently circulated coins are controlled by how many addresses, how many users etc... Surprisingly less than 16000 addresses control like 67% of all the coins in circulation. Less than 120k Addresses control 93% of all coins, in my mind this means their are less than 120k Bitcoin users that can significantly affect the price. 16000 that can really move the market price down.

Can't really speak to collaboration, second one is more funny: Adam Back has answered a few questions of mine in the past. One day in SF, I was dining upscale Chinese and in walks Gavin + a few guys working on the Lightning Network. |

I actually think it should reside in the Altcoin Subforum as well TBH.
It's not about Stellar. "First provably safe" implies that security of Bitcoin is questioned. Anyway, I noted your opinion, next time I'll be more explicit in an OP. If its not about Stellar, can you make sure to remove the Bright Red Text marked "Stellar" Seems like your advertising that consensus protocol over Bitcoins. |

Just that this probably belongs in the Altcoins subforum and that I still wouldn't touch Ripple or Stellar with someone else's bargepole. Just can't seem to shake the shady impression I get from them. Plus the fact that their whole approach is to jump in bed with the banksters first and worry about what's best for everyone else later. Yuck.
It doesn't belong to Altcoins subforum. They say that Bitcoin security is weak because it's unknown who miners and what their intents are. I actually think it should reside in the Altcoin Subforum as well TBH. Stellar is a clone of the Ripple Source code with modifications, just like Altcoins: Litecoin/Darkcoin etc. Their is no way that storing value on Stellars Network is more Secure than the storing that value on the Bitcoin network currently. The cost to weaken Stellars Network and the cost to weaken Bitcoins network are not comparable. Stellar's Coin Distribution is a bit better than I actually thought it would, after looking at their information online. However their currency appears too be centrally distributed and determined by some central authority other than 6% of the currency. (50% for the world via the direct signup educational program, 25% for nonprofits to reach underserved populations via the increased access program, 20% for the bitcoin program, 5% for operational costs and their is a fixed 1% inflation rate so your Stellar depreciates in value overtime.) I think Doomad is right, we are just seeing 'Altcoins' with larger funding these days. I remember a year or so back these altcoins did-int have any companies/money behind them and most petered out quickly. I have a sinking feeling we are just now starting to see some of these massive overfunded scam coins come to fruition, Paycoin was a recent one I saw some newbies jump into thinking that its something innovative/new. Another piece of information to anyone still reading, Stellar is created by an ex Mt. Gox employee, who knows, with Stripes involvement/funding it might actually be a moderately successful altcoin and end up like: Litecoin, Monero, Ripple, etc. and satisfy some need. Edit: I had no idea Stellar was a fork of Ripple, thought it was a fork of Bitcoin. |

Please consider this, the top 1699 Richest Bitcoin Addresses, everyone at least owns 1k bitcoin! http://bitcoinrichlist.com/top100?page=17According some analysis, their hoarding is still increasing. Most of the newly minted coins probably just go to their wallet! But I do agree you conclusion! The more users, the more scarcity of bitcoin will become! I agree a few participants in the network will own a disproportionate amount of the coins, in my mind anyone who has more than 7 has more then their "share". If anyone owns more than 7 Right now they have purchased more than their given ratio, the reason this is ok now is not many users buy more than 1 Coin so theirs always 1-6 BTC available for the richest to purchase up. When we get more users, their ability to purchase whole BTC's will be impeded severely as more participants change the ratio of available coins to users. Thank's for linking this, I have been to this site a few times before in the past, looks like the UI has been updated a bit. I guess it did not occur to me to look at it and take any of these numbers into consideration. I wish the site had a restapi or something to query, but its easily parse-able. I think the real reason I avoided looking at individual addresses is its not quite indicative of how many coins are available to a given user in the network. Looking at those numbers it is surprising to me that we only have 15k Addresses with more than 100 Coins, this will allow me to create a more tailored distribution model Bitcoin currently has though. |
