Countless individuals and companies have lost their bitcoins due to compromised private keys. Multisignature transactions offer a solution to this problem. They just need to be user-friendly. That is the idea behind Cosign, a multisignature wallet being developed by the Bitcore team. It should be just as easy to spend multisignature bitcoins as regular (“single signature”) bitcoins, except other people (or computers) have to sign the transactions before they are valid. The way this works is that when someone from a, say, 3-of-5 multisignature wallet wishes to spend bitcoins, they can spend the bitcoins just like normal. This provides another layer of protection for theft. Though easy to use, Cosign takes every measure to retain the full security of multisignature transactions.

Dark Wallet Will Make Bitcoin Accessible for All—Except the Feds. Bitcoin, the digital currency once known for powering the black market of the deep web, has officially caught the attention of the proverbial Man. The US government is working to regulate and control the crytocurrency; law enforcement is confiscating millions of virtual coins used for illegal transactions; and venture capitalists and entrepreneurs are chomping at the bit to profit from the hype.
While capitalist society embraces the futurist money, the bitcoin community is left at something of a crossroads: Do you play nice with the establishment, or reject it and dive deeper into the underbelly of the web? The developers of Dark Wallet wholeheartedly subscribe to the latter mindset. The group, called UnSystem, are self-proclaimed cryto-anarchists led by Cody Wilson—who you may remember as the creator of the controversial 3D-printed gun. The group launched an Indiegogo campaign yesterday to raise $50,000 to build Dark Wallet, which they expect to launch early next year.
