NEW YORK (MainStreet) If you think of Bitcoin as a currency, something you merely get from an ATM, you're missing the point. Bitcoin is actually a protocol, an open source cryptographic system that can operate on a peer-to-peer network.
Yes, it can be used to create a commodity people call "virtual money." A single bitcoin is merely a long encryption key whose identity is verified by being added to the ledger of Bitcoin transactions, a process called "mining."
There can be only 21 million individual encryption blocks, according to the protocol. Thus the supply of bitcoins is controlled.
It's this control that makes Bitcoin into what some call a "virtual currency" that can be traded, exchanged for other goods and services and used to create a virtual financial system outside any government regulation. But it is, in fact, a digital commodity.
From a regulatory perspective, the difference is important.
Bitcoin fans like to point to a 2006 interview with Milton Friedman, where he proposed that a computer control the money supply to limit its growth, as their inspiration for a Bitcoin-based currency.
At the heart of the protocol is the block chain, a database of unique, encrypted identifiers. Right now the technology is being used to identify individual Bitcoins.
But a block chain can be attached to anything, Schmitz says. You can attach a block chain to any copyrighted work, so digital property can be identified when someone pirates it. It can be attached to legal documents, authenticating them even in a digital form.
The block chain is, in short, an identification technology.
Thinking of Bitcoin as "virtual money" is like thinking of a 1979 Apple II as a Visicalc machine, or thinking of a 1985 Macintosh as a desktop publisher. It's confusing an application with the platform it rides on.
