Our vision is to enable extremely low-cost access to deep space. We are developing the CubeSat Ambipolar Thruster (CAT), a new rocket propulsion system powered by the Sun and propelled by water, which will push small spacecraft like CubeSats around and far beyond the Earth. New propulsion technologies can cost billions of dollars and take a decade to build and launch. CAT will be one of least expensive and most rapidly developed deep-space-capable systems ever built.
Sheep Marketplace closed down over the weekend after someone got away with 96,000 bitcoins - and angry users are chasing him around the internet.
All day, we’ve been chasing the scoundrel with our stolen bitcoins through the blockchain. Around lunchtime (UK), I was chasing him across the roof of a moving train, (metaphorically). I was less than 20 minutes, or 2 blockchain confirmations, behind “Tomas”.
He was desperately creating new wallet addresses and moving his 49 retirement wallets through them, but having to wait for 3 or 4 confirmations each time before moving them again. Each time I caught up, I “666”ed him - sent 0.00666 bitcoins to mess up his lovely round numbers like 4,000. Then,all of a sudden, decimal places started appearing, and fractions of bitcoins were jumping from wallet to wallet like grasshoppers on a hotplate without stopping for confirmations.
He was tumbling our stolen bitcoins a second time, and a tumbler is unbeatable….
Unless you guess which one it is, nearly all the coins belong to the person you’re tracking, jump in with him, and get jumbled up through the same wallets using the same algorithm. I was hopping from foot to foot shouting “come on!” at my laptop, waiting an age for 6 blockchain confirmations to get 0.5 btc into “bitcoin fog”. My half a bitcoin got sliced and diced through loads of wallets and I followed the biggest chunk with blockchain.info - along with 96,000 stolen ones!
