Bitcoin P2P Currency

Open source innovation: Bitcoin

Alternative currencies for e-commerce have been attempted many times, but never one quite like Bitcoin. Its creator, Satoshi Nakamoto, has dubbed it a "cryptocurrency," because it relies on public/private key cryptography to facilitate electronic trading in a completely anonymous, secure, peer-to-peer fashion.

Bitcoin P2P Cryptocurrency

Bitcoin is a peer-to-peer network based digital currency. Peer-to-peer (P2P) means that there is no central authority to issue new money or keep track of transactions. Instead, these tasks are managed collectively by the nodes of the network. Advantages:

• Transfer money easily through the Internet, without having to trust middlemen.
• Third parties can’t prevent or control your transactions.
• Bitcoin transactions are practically free, whereas credit cards and online payment systems typically cost 1-5% per transaction plus various other merchant fees up to hundreds of dollars.
• Be safe from the instability caused by fractional reserve banking and bad policies of central banks. The limited inflation of the Bitcoin system’s money supply is distributed evenly (by CPU power) throughout the network, not monopolized by the banks.

Bitcoin is an open source project created by Satoshi Nakamoto, and is currently in beta development stage. Bitcoin development is hosted at SourceForge.

Anonymous internet banking

Anonymous Internet Banking is the name given to the proposed use of strong financial cryptography to make electronic bank secrecy (or more precisely pseudonymous banking) possible. The bank issues currency in the form of electronic tokens that can be converted on presentation to the bank to some other currency. This concept has a long history in which free banking institutions have issued their own paper currency often backed by a physical commodity.

[...]

Examples of anonymous internet banking services that have already been implemented include:

• Bitcoin: open source peer-to-peer electronic cash system that's completely decentralized, with no central server or trusted parties.
• eCache: an anonymous bank operating over the Tor network.
• Pecunix: an (optionally?) anonymous digital gold currency.
• Yodelbank: an anonymous bank built on top of various digital gold currencies which ended operations during November 2005.

Peer-to-peer

A peer-to-peer, commonly abbreviated to P2P, is any distributed network architecture composed of participants that make a portion of their resources (such as processing power, disk storage or network bandwidth) directly available to other network participants, without the need for central coordination instances (such as servers or stable hosts).^[1] Peers are both suppliers and consumers of resources, in contrast to the traditional client–server model where only servers supply, and clients consume.

Digital Ants Protect Computers

clipped from www.treehugger.com New Biomimicry in Digital Security - Ants Swarm to Protect Computers Science Daily reports that biomimicry is playing a key role in upcoming computer security technology. By looking at the way ants call for backup and overpower invaders through sheer quantity of soldiers, security experts have devised a "digital ant" that will help human operators more quickly spot threats to computer systems. clipped from www.telegraph.co.uk Ants inspire new computer antivirus software Scientists have studied the behaviour of ants to develop a new generation of antivirus software for computers. clipped from www.wfu.edu Computer science professor Errin Fulp works with graduate students Brian Williams (center) and Wes Featherstun (far right), who worked this summer at Pacific Northwest National Laboratory developing a new type of computer network security software modeled after ants. Computer security mimics nature Unlike traditional security devices, which are static, these “digital ants” wander through computer networks looking for threats, such as “computer worms” — self-replicating programs designed to steal information or facilitate unauthorized use of machines. When a digital ant detects a threat, it doesn’t take long for an army of ants to converge at that location, drawing the attention of human operators who step in to investigate. The concept, called “swarm intelligence,” promises to transform cyber security because it adapts readily to changing threats.

“Cloud” a Digital Sculpture in Heathrow Terminal 5.

A digital sculpture for British Airways Heathrow Terminal 5, whose surface is covered with flip-dots that can be individually addressed by a computer to animate the entire skin of the sculpture.

clipped from www.thinkartificial.org Created by Troika, an art and design studio in London, “Cloud” is a digital sculpture housed at the luxury lounges in Heathrow Terminal 5. It’s a smooth-shaped object suspended in the air, covered with 4638 “flip dots” - motorized metal patches that change orientation to produce various patterns. clipped from www.youtube.com clipped from troika.uk.com TROIKA // TROIKART / TROIKA DESIGN / TROIKA COMMUNICATIONS / news / about / clients / press / contacts / clipped from troika.uk.com The sculpture is located in Terminal 5 in the atrium hall which leads to the British Airways First Class Lounges. The brief from British Airways was open and simple: to create a signature piece that will mark the entrance of the First Class Lounges and signify the transition between the busy shopping floor and the calm and serenity of the lounges.
