Net Currency Bitcoins



A hacker group has recently claimed that it has stolen Mitt Romney’s tax returns. The files were allegedly obtained from the Tennessee office of the big accounting firm, PricewaterhouseCooper, on August 25.

The hackers have threatened to make the files public on September 28 — unless they are paid $1million in Bitcoins, the online currency. Bitcoins are difficult to trace or identify.

Bitcoin is a decentralised digital currency. It is money that can be transferred directly from one person to another on the Net, without going through a bank or clearing house. It is the cheapest way to move money around because you just have to pay a voluntary fee.

You can use them in every country, there are no prerequisites or set limits and your account can never be frozen. Anybody can generate Bitcoins on the Internet by running a free application called the Bitcoin Miner.

Mining requires a certain amount of “work” for each block of coins. The amount that is mined is automatically adjusted by the network so that only a limited and predictable number of coins is generated. They are then stored in your digital wallet.

When you transfer Bitcoins, an electronic signature is added. Bitcoin verifies transactions with a state of the art encryption that is used in military and government applications. After it is verified it is permanently and anonymously stored in the network.

Bitcoin is open source. Unlike a normal bank, the Bitcoin database is a decentralised database. No individual owns it. It is maintained by a community of open source developers.

If the Bitcoin idea takes root, it will revolutionise business on the Net and beyond it just the way Steve Jobs and Steve Wozniak changed computing with their personal computers, or the web changed publishing.

Bitcoins have a checkered past. Where the Euro failed, it is really conditioning people to a single world economy as well as currency. There is still a lot of work to be done on it and many questions are unanswered.

For example who determines the mining work that is required to make them? How secure is it? Wouldn’t it be easy to hack and manipulate accounts if you are careless?

Even with all these questions, it has a devoted following among libertarians and techies. Above all, trading in Bitcoins is becoming popular even in India.
