We’ve got a Butterfly Labs Bitcoin miner, and it’s pretty darn fast
Apparently, I’m a Bitcoin miner now, and it looks like I’m actually pretty good at it. Ars is currently in possession of one of the elusive but very real Butterfly Labs Bitcoin Miners. It’s a tiny little black box that fits in the palm of my hand, and it contains a specialized ASIC adept at chewing through SHA-256 cryptographic functions—exactly the kind of calculations necessary to bring more Bitcoins into the world. Turns out, it’s very good at what it does: it computes hashes at the rate of about 5.3 billion per second.
