It's practically impossible for regular people to buy Bitcoin

Paranoia appears to be the order of the day, given what we know about the NSA and GCHQ thanks to Edward Snowden. Absent from the stories so...
How do you encrypt a file such that it can be decrypted after a date, but not before? Use serial computations for proof-of-work using successive squaring, chained hashes, or witness encryption on blockchains.
2011 essay on how Bitcoin’s long gestation and early opposition indicates it is an example of the ‘Worse is Better’ paradigm in which an ugly complex design with few attractive theoretical properties compared to purer competitors nevertheless successfully takes over a niche, survives, and becomes gradually refined.
The new Snowden revelations are explosive. Basically, the NSA is able to decrypt most of the Internet. They’re doing it primarily by cheating, not by mathematics. It’s joint reporting between the Guardian, the New York Times, and ProPublica. I have been working with Glenn Greenwald on the Snowden documents, and I have…
Random numbers are critical for cryptography: for encryption keys, random authentication challenges, initialization vectors, nonces, key-agreement schemes, generating prime numbers and so on. Break the random-number generator, and most of the time you break the entire security system. Which is why you should worry…
The founder of Liberty Reserve , a digital currency that has evolved as perhaps the most popular form of payment in the cybercrime underground, was reportedly arrested in Spain this week on suspicion of money laundering. News of the law enforcement action may help explain an ongoing three-day outage at…
I won’t discuss anything in this post. I’m tired of discussing technical things with people with skewed opinions and monetary interest. I’ve talked enough in the Bitcointalk forum…
Wow, what the heck is going on with Bitcoin? When I started this post, the value of a single bitcoin had surged upwards of $250. It’s corrected a bit since then (down $100 or so), but it̵…

On a NIST-sponsored hash function mailing list, Jesse Walker (from Intel; also a member of the Skein team) did some back-of-the-envelope calculations to estimate how long it will be before we see a practical collision attack against SHA-1. I’m reprinting his analysis here, so it reaches a broader audience. According…
NIST is about to announce the new hash algorithm that will become SHA-3. This is the result of a six-year competition, and my own Skein is one of the five remaining finalists (out of an initial 64). It’s probably too late for me to affect the final decision, but I am hoping for “no award.” It’s not that the new hash…

I've mentioned Bitcoin a number of times on this blog. It is something our firm is watching closely. We thought briefly about making a Bitcoin specific investment earlier this year but ended up deciding to sit on the sidelines for now. We are quite taken with the idea of a currency that is not controlled […]
Digital, but still a barbarous relic.
TL;DR Bitcoin is not inherently anonymous. It may be possible to conduct transactions is such a way so as to obscure your identity, but, ...
