In practice, digital counterfeiting is much easier. Satoshi's solution was what has become known as the blockchain: It's like a giant interactive spreadsheet everyone has access to and updates to confirm each digital credit is unique. It is this technology that programmers are now working to deploy for uses that go far beyond Bitcoin. Satoshi does not appear to have been looking to solve this problem when he created Bitcoin. Satoshi and the blockchain really solved that problem in an elegant and unexpected way.
The breakthrough means that, theoretically, any act of commerce on the Web can be decentralized and stripped of a controlling authority. Perhaps the most straightforward example of a post-Bitcoin service using Satoshi's blockchain is Proof of Existence. Neither its contents nor your own personal information are ever revealed — rather, all the data in the document gets digested into an encrypted number.
Proof of Existence is built on top of the Bitcoin blockchain there's a 0. A slightly more politicized application of the blockchain is a project called Namecoin. But three years ago, engineers developed Namecoin, which serves as a new domain-name system for registering Web addresses that end in ". Again, blockchain technology makes it so that something that previously required a centralized authority can now be managed via community.
You may have heard this before, but Luria explained why the blockchain is the true threat: Most processors use hub-and-spoke models, he said, which are able to charge fees for crossing jurisdictions, and for smaller transaction amounts. Decentralizing and distributing the network gets rid of all that. A startup called Ripple represents the most active threat to the mega-processors.
We profiled Ripple, and the group that created it, last month. Computers all familiar with each other on Ripple's network mutually agree on changes to its blockchain Ripple calls it a "ledger".
This allows transactions to be processed instantly and without a third party. It's even faster than the Bitcoin network, because everyone using the Ripple ledger gets their own copy of the whole ledger, in contrast with the nodes on the Bitcoin network all sharing a single one.
The blockchain is even stalking credit-card companies. Even sending money through Venmo, the app that lets you text your friends for picking up dinner that one time, still takes five days to clear. Of course, it's possible the existing financial behemoths could adopt their own blockchain technologies. He calls such futuristic entities distributed autonomous corporations.

Incidentally, he said having a conference called Inside Bitcoins was akin to having a conference called Inside AltaVista. There are, of course, loads of technological and regulatory hurdles that must still be overcome for all of this to materialize. And there are plenty of things that could be reset on a blockchain. But investors don't seem too concerned: He refers to this moment as the blockchain cycle: Our fund was built during social. Our fund was built during social and the emergence of mobile.
Our fund was built during the mobile downturn. And our fund will be built during the blockchain cycle. I am looking forward to it. We'll leave you with an extremely futuristic example of how the blockchain could be deployed. In a talk given last fall at the Turing festival , Mike Hearn, a former Google employee who quit his job to work full-time on Bitcoin, laid out this scenario: A something Scottish girl named Jen wants to meet up with her friends downtown.
She doesn't own a car — no one does in the future — so she dials up a cab through a network Hearn calls TradeNet. Metronome will be launched in early December with an auction of 10 million coins. The founders will be issued two million coins from that batch as compensation for their work in developing the software.
Subsequently, the cryptocurrency plans to issue 2, new coins daily. Based on calculations by American Banker, this should enable the currency to reach a supply of above 30 million in the next 20 years. That self-assessment may be a tad enthusiastic. Bloomberg has also listed a couple of challenges for the token, such as an increasingly crowded cryptocurrency ecosystem and zero users at start.
