Interview: How Bitcoin Created a Decentralized Crypto-Currency. Bitcoin is an open source, peer-to-peer electronic currency created by Satoshi Nakamoto and maintained by a small team of developers. As part of what's turning into an ongoing series on the distributed Web, I talked to contributor Gavin Andresen about how the software works. This is a technical overview. If you're interested in an economic or political look at the software, you can read the Wikipedia entry or Niklas Blanchard's essay on the project. Klint Finley: Could you give us a brief overview of what Bitcoin is for the unfamiliar?

Gavin Andresen: Sure. Bitcoin is the first peer-to-peer currency - it is money created by people instead of by a central bank or government. And how does it work? Everybody trying to create bitcoins and everybody trading bitcoins is connected by a peer-to-peer network. The really novel idea is a mechanism for preventing bitcoins from being spent more than once WITHOUT relying on a central authority. Why is that? But what if the IRC server gets shut down? Quantum money from Knots. Peter Shor who developed a quantum algorithm for factoring primes, is now discussing quantum money. Money, either in the form of bills or information on a computer, should be impossible to copy and also should be verifiable as good money when tendered to a merchant. Quantum mechanics may make this possible to achieve with far greater security than can be achieved without quantum mechanics.

Quantum money is a cryptographic protocol in which a mint can produce a quantum state, no one else can copy the state, and anyone (with a quantum computer) can verify that the state came from the mint without sending the money back to the mint. I will present a concrete quantum money scheme based on quantum superpositions of diagrams that encode knots. This scheme is hopefully secure against computationally bounded adversaries.
