‘Dark Wallet' Is About to Make Bitcoin Money Laundering Easier Than Ever

``If, say, Alice is buying alpaca socks from an online sock seller and Bob is buying LSD on the Silk Road, Dark Wallet will combine their transactions so that the blockchain records only a single movement of funds. The bitcoins simultaneously leave Alice's and Bob's addresses and are paid to the sock seller and the Silk Road. The negotiation of that multi-party transaction is encrypted, so no eavesdropper on the network can easily determine whose coins went where. ''
