1  Bitcoin / Armory / Failed import of private key on: April 13, 2013, 05:05:18 AM
I'm trying to import the private key from a Bitcoin Wallet address. The private key is as follows (don't worry, I'm deleting the address from my wallet): Kz9Eyg1rL27RnkUmmkofeyxdbWSn7ARQTdCiVKHLKxdhrMGNj

When I try to import that into my Armory wallet, I get the error message:

The private key you have entered is actually not valid for the elliptic curve used by Bitcoin (secp256k1). Almost any 64-character hex is a valid private key except for those greater than:


Please try a different private key.

This imports fine into applications such as, however, and even display the correct public address. The associated public address is: 1N6TrY9HKhwS4G1AmAB1V7BjckqD7BtT2F
2  Bitcoin / Press / 2013-03-14 Digital Cash Finds Foothold In NH on: March 14, 2013, 10:39:02 PM
Back at the Pao Cafe in Newmarket, Matthew Carrano says he’s more than happy when his customers pay in Bitcoin:

“I believe in Bitcoin as a long term money supply. I don’t know if you’ve seen it, but Bitcoin has gone up in value versus the dollar quite a lot. I don’t have a lot of Bitcoin customers but when I do I’m content to hold on to the Bitcoin.”
3  Economy / Services / Porcupine Freedom Festival in NH Accepting BTC for Registration on: February 12, 2013, 03:46:58 PM
The annual Porcupine Freedom Festival (PorcFest), put on by the folks from the Free State Project in New Hampshire, is now accepting bitcoins for the registration fee (35 USD). Last year, PorcFest was one of the biggest celebrations of real-world Bitcoin commerce the world has seen, and this year it will take on a whole new level.

Check out the thread from last year, and come join us in the White Mountains of New Hampshire.
4  Bitcoin / Armory / Encrypted Paper Backups on: January 30, 2013, 10:58:53 PM
I know this has been discussed before, but here's why I think encrypted paper backups would be a good idea. Possibly the most realistic failure mode is that the original binary wallet will get corrupted. You could make a few copies on flash drives, but those aren't that reliable either. You could put it on the cloud, but that opens up some more risk. Of course that's why we have paper backups. But I personally wouldn't want to put an unencrypted paper backup in a safety deposit box in a bank. I do think that's a pretty good place for an encrypted paper backup, though.

I don't expect to forget my password anytime soon, so if my digital backups fail, I can always go get that paper. I'll also keep my unencrypted paper backups, in case I do forget my password, but I feel I have to be much more careful with those. Since I don't want to make multiple copies of the unencrypted paper backups, they're more susceptible to loss and damage.
5  Bitcoin / Armory / 2-of-3 Paper Wallets on: January 29, 2013, 02:48:17 AM
I've been playing around a lot with Armory as an offline wallet, and the one thing that would make me sleep better would be a 2-of-3 series of paper wallets. Right now you can only print a single wallet page, so if somebody breaks in to your house and gets it, they have all your coins. If Armory used something like ssss-split to print out three pages, where any two of them were needed, you'd be able to put them in three different places, making it very unlikely any thief would get to two of them. At the same time, you could lose one of three and still be able to reconstruct your wallet.

Does anybody else feel this would be a cool feature?
6  Economy / Trading Discussion / Dwolla Begins PayPal-Style Account Suspensions on: January 25, 2013, 06:30:29 AM
It's getting harder and harder to use fiat money to buy bitcoins:

Dwolla has moved beyond closing the accounts of those it can prove are operating unlicensed exchanges and has begun closing the accounts of private individuals based on a mere affiliation.

It’s not just some random Bitcoiner they began with, either. On Wednesday, January 23rd Dwolla suspended the account of StompRomp founder Josh Harvey. Here are the circumstances...

10  Bitcoin / Press / 2012-12-05 - Custom Chips in a Bitcoin Gold Rush on: December 05, 2012, 07:05:51 AM
The emergence of bitcoin-mining ASICs is part of a computational arms race rooted in the complex cryptographic scheme designed by Bitcoin’s anonymous inventor, known only by the online name Satoshi Nakamoto. Under Nakamoto’s rules, which are what allow the currency to function without control by a central bank, miners run free software that communicates over the Internet to maintain a distributed global log of all Bitcoin transactions.
11  Bitcoin / Press / 2012-12-03 - Bitcoin Virtual Currency Newest Payment Option on: December 03, 2012, 06:56:37 PM
One example of a successful offering in the online poker world is Switch Poker which started giving patrons the option of Bitcoin currency about a year ago. The poker room has stepped it up a notch and will be offering a Bitcoin only sector. This move is in response to those players who are devotees of the virtual currency who wanted to be able to leave there accounts in Bitcoin money to play.

Online gaming sites are not the only business converting to the optional currency. Recently the popular WordPress online publishing service announced it would begin accepting Bitcoin as payment for various upgrades. Andy Skelton a spokesperson for WordPress said, “PayPal alone blocks access from over 60 countries and many credit card companies have similar restrictions … “

Overall quite positive. Some strange beliefs about fiat currencies, though:

The idea that BItcoins are safer because they are not connected to the gold standard currency world is disputed by some who think that Bitcoin is destined to fail.
12  Bitcoin / Press / 2012-11-29 - Dollar-Less Iranians Discover Virtual Currency on: November 30, 2012, 02:36:08 AM
Anyone in the U.S. downloading songs, which fetch .039 bitcoins or 45¢ each, risks violating U.S. sanctions. That doesn’t bother Rafigh, who’s studying computer engineering as well as playing music. “Bitcoin is so interesting for me,” Rafigh wrote in an e-mail. “I wish the culture of using digital money spreads all over the world, because it does not have any dependency on anything like politics.” Rafigh has translated some bitcoin software into Farsi for his friends. “I love Iran, and if bitcoin is good for me, it can be good for more Iranians like me.”

A spokesperson for the company said, “It turns out that poker players like Bitcoin! We have had many requests for Bitcoin only tables so that players can play poker with their Bitcoins without needing to first convert them to Euro on the site and then back to Bitcoins to withdraw their winnings.

17  Bitcoin / Press / 2012-11-16 - Miner problem: big changes are coming for Bitcoin on: November 16, 2012, 10:11:53 PM
Miners have dutifully generated just under half of the total Bitcoins that will ever be mined. But the mining industry is about to be thrown into turmoil due to two major changes expected to hit, entirely coincidentally, around the same time. One is the introduction of application-specific integrated circuits, or "ASICs," designed specifically to mine Bitcoins up to 1,000 times faster than current technology. The other is a deadline hard-coded into the Bitcoin software. When the total number of Bitcoins reaches 10.5 million in about one week, the block reward will suddenly be cut in half — a protection built into the currency in order to prevent inflation.
18  Bitcoin / Press / 2012-11-16 - A win for Bitcoin legitimacy: WordPress on: November 16, 2012, 10:08:36 PM
Some new quotes from WordPress in here:

WordPress said it decided to start accepting Bitcoin because of its “role” as a universal currency. PayPal and a number of credit card companies actually restrict transactions in certain parts of the world due political circumstance, high criminal activity, and more.

Currently, few legitimate businesses accept Bitcoin, which has primarily been used for black market (aka mostly illegal) transactions. And since banks aren’t involved with Bitcoin transactions, purchases don’t leave a “paper” trail for law enforcement agencies to track criminal activity.

U.S. federal government isn’t too fond of Bitcoin — and with good reason. A universal currency like Bitcoin could hypothetically destabilize a government’s capability to regular its finances. And if that happens, it could disrupt their authority.
But despite any negative connotation attached to Bitcoin in the past, WordPress’ intentions seem entirely pure.

“I think the technology is value-neutral,” WordPress creator and Automattic founder Matt Mullenweg told VentureBeat via email. “I’m sure many people use paper dollars and euros for bad things as well, but that doesn’t mean they’re intrinsically bad (or good).
19  Bitcoin / Press / 2012-11-16 - WordPress to accept bitcoins due to credit card blocks on: November 16, 2012, 10:03:45 PM
WordPress said Thursday it will accept bitcoins, opening up the blogging platform to payments from users in countries not supported by PayPal or credit card companies.

WordPress is free, open-source software, but the company Automattic offers paid-for features such as blog designs, custom domains, hosting partnerships and anti-spam measures.

As with many Web-based services, payments for those features are dependent on credit card transactions and eBay's PayPal service. But WordPress wrote on its blog that PayPal doesn't serve more than 60 countries, and credit card companies have restrictions due to political, fraud and other reasons.
20  Bitcoin / Press / 2012-11-16 - WordPress Brings Bitcoin to the Blogging Masses on: November 16, 2012, 09:49:33 PM
Upgrading your blog no longer requires a credit card or PayPal account. Starting today you can raid your virtual piggy bank to pay for WordPress upgrades with the digital currency Bitcoin.
The move makes WordPress one of the largest, most reputable online services to accept the fledgling Bitcoin currency.
