The below article comes from New Scientist. And if you think that Bitcoin is just about money, think again. The technology around Bitcoin may be far more, for a lack of a better description at the moment, robust.

Bitcoin is money – people can use it to buy anything 
from pizza to plastic surgery. The meteoric rise of the online currency 
has caused everyone from financial regulators to law enforcement to the 
US Senate to stand up and take notice.
 But a growing group of computer scientists think this is just the 
beginning. They are convinced that Bitcoin's real value is not in 
providing the world with a currency free from government intervention, 
but in the technology which underpins it, a secure system of verifying 
transactions that they believe has the potential to vastly disrupt the 
way we exchange goods and services around the world.
The secret to Bitcoin's rampant success is
 the "block chain" – a secure digital ledger that tracks coins across 
the internet. It records every single transaction of the currency, and 
those transactions are then 
mathematically verified by the computers of Bitcoin users
 around the world. Anyone who holds bitcoins also has an exact copy of 
the block chain, making it virtually impossible to create a forgery. 
This eliminates the need for trusted third parties, like PayPal and 
Visa, to take part in financial transactions.
Now the block chain is being applied 
beyond the movement of money using a technique called "colouring" 
bitcoins. It has the potential to transform commerce. Take the buying 
and selling of real estate, for example. In a statement before the US 
Senate Committee on Banking, Housing and Urban Affairs on 19 November, 
Anthony Gallippi, CEO of Bitcoin payment firm BitPay, described how 
co-opting the block chain could do away with the gaggle of fees and 
legal manoeuvrings that usually accompany home sales.
"The biggest upfront costs for consumers 
trying to buy a home are the closing costs, which include fees for 
deeds, titles, stamps, title insurance, and other redundant tasks to 
record the sale in different record books," Gallippi said. "Bitcoin can 
replace thousands of dollars in closing costs with a single transaction 
that costs 5 cents. By reporting deeds and titles on the block chain, 
the information would be public record forever, for pennies, and 
eliminate the need for title insurance."
Indelible record
Colouring bitcoins is a way of digitally 
labelling a bitcoin or a fraction of one with information about a 
transaction. When the labelled coin changes hands, it gets indelibly 
recorded in the block chain. It's the equivalent of recording the sale 
of a flock of sheep by writing a message to that effect on a $1 bill, 
and giving that to the buyer – only with Bitcoin, that record is 
mathematically confirmed nearly instantly by computers all over the 
world.
A few researchers have already done this. Amos Meiri, a computer scientist with the social stock-trading firm eToro,
 based in Cyprus, says he ran a proof of concept last year. He 
transferred a Bitcoin, coloured to represent a sum of gold, through the 
block chain. Through an organisation called Colored Coins, Meiri and others plan to launch a beta version of software that executes this process in the next few weeks.
"I'm able to issue one coloured coin which
 resembles 1000 shares of stock, and sell it to you," Meiri, says. "When
 I sell it to you I give you all the rights for voting and dividends 
without paying a commission to stock markets or brokers. We basically 
put another layer above Bitcoin. Instead of holding the currency, you'll
 be able to hold and trade gold, Apple stock, your own car."
Others are building similar services. Mike Hearn,
 a computer scientist based in Zurich, Switzerland, has developed an 
application called PayFile which uses Bitcoin's block chain to keep 
track of a user's downloads, and pay for bandwidth automatically as they
 go. Hearn says PayFile is more a demonstration of what the Bitcoin 
ledger can do, rather than a fully fledged commercial service, but says 
it points to a future where the block chain will be used for all sorts 
of transactions.
 All I have to say is wow, if you cannot see the disruptive innovation aspects in that.
