  • Blockchain, the key technology behind Bitcoin, is a new network that helps decentralize trade, and allows for more peer-to-peer transactions. WIRED challenged political scientist and blockchain researcher Bettina Warburg to explain blockchain technology to 5 different people; a child, a teen, a college student, a grad student, and an expert.

    Check out WIRED's guide to blockchain:

    I don’t understand it completely but I can’t get whether is it a good thing we don’t know the person or bad ? Will this make fair trade easier or harder because we don’t have the whole story

    But how can we make sure both persons hold their word? That the other person actually sends the stuff and the other actually pays for it?

    14:35 I dont want my wallet doing anything on its own. I appreciate you addressing an intellectually challenging topic but I'm disappointed you somehow dressed this up as something a 10 year old could understand. Or want or need to understand.
