Bitcoin (www.bitcoin.org) is a peer-to-peer currency. Peer-to-peer means that no central authority issues new money or tracks transactions. These tasks are managed collectively by the network.

Bitcoin (www.bitcoin.org) is an Internet based virtual currency. Bitcoin is a unique currency because transactions that take place in the Bitcoin network do not go through any central agency. Instead, Bitcoin transactions are transmitted and verified in a peer to peer network consisting of computer systems running the Bitcoin node software, which is open source. Every transaction on the Bitcoin network is recorded within each network node. Bitcoin transactions are usually fully verified within 1 hour, are irreversible and are not susceptible to double spending (e.g. sending the same bitcoin to 2 people at the same time). Since Bitcoin is open source and the transaction verification cost is spread among a large number of nodes in the network, transactions are nearly free to process. Also, because Bitcoin does not go through a central agency, it can be implemented in an application with no institutional restrictions that are found with other proprietary online payment systems.

WHO should attend?

Anyone who is interested in learning and playing with Bitcoin. We encourage innovators and developers who like to be hands on in leveraging this powerful new method of payment on the Internet to create something amazing at this Hackathon.

Bitcoins are an excellent choice for developers looking for a better way to do micropayments or international remittances. Due to the extremely low cost of transacting in bitcoins, an entity that wants to remit money to a number of contributors from a variety of other countries only has to get bitcoins to do so.

The Bitcoin Challenge...

Everyone is welcomed to bring their own ideas, Jordan & the Bitcoin hackathon team will also throw out various challenges. Here are some examples of various Bitcoin Challenges, you can read up on them to get a headstart (more to share at event)

- Write a mobile application that can use a credit card to buy Bitcoins.   

- Write a simple Bitcoin economy search engine that can be used to find goods and services that are for sale in Bitcoin. Using the search engine back end API, sites should be able to display products that can be purchased using Bitcoin. 

- Write a web plugin that can automate the process of using the Amazon wishlist to buy products from Amazon using Bitcoin.   

- Add a Bitcoin betting feature to an existing open source board game (e.g. Chess), that allows two players to place bets against each other, with the winner automatically receiving the Bitcoin payout from the other player’s bet.  - Write a simple web app that allows someone to post a project description and a Bitcoin address to receive donations. The app should display the amount of Bitcoins that have been donated to the project. 

-Write a simple version of CodeCoin for the programming language of your choice. CodeCoin allows someone to upload a specification for a small program written in a particular language along with a suite of pre-set unit tests and specified run time constraints as a 'code challenge'. Additionally, they send a certain amount of Bitcoin to an escrow Bitcoin address that is tied to the code challenge. CodeCoin then automatically  tests submitted programs and dispenses Bitcoins to successful  submitters.

The Pieshare Prize

We will be using a pre-alpha preview of the PieTrust reputation system to collectively decide how to distribute the prize pool. All participants will use the PieTrust system to give their opinion on all the projects, and PieTrust will tell us how to divide the money.
