Scalability The core Bitcoin network can scale to much higher transaction rates than are seen today, assuming that nodes in the network are primarily running on high end servers rather than desktops. Bitcoin was designed to support lightweight clients that only process small parts of the block chain (see simplified payment verification below for more details on this). A configuration in which the vast majority of users sync lightweight clients to more powerful backbone nodes is capable of scaling to millions of users and tens of thousands of transactions per second. Scalability targets VISA handles on average around 2,000 transactions per second (tps), so call it a daily peak rate of 4,000 tps. PayPal, in contrast, handles around 4 million transactions per day for an average of 46 tps or a probably peak rate of 100 tps. Let's take 4,000 tps as starting goal. Current bottlenecks Today the Bitcoin network is restricted to a sustained rate of 7 tps by some artificial limits. The protocol has two parts.

Bitcoins: Why They're More Than a Bubble The volatile rise-and-fall of Bitcoin has prompted lots of stories explaining why the online virtual currency is a classic bubble. Many compare it to tulip mania in 17th century Holland, where prices of rare tulip bulbs soared to absurd heights and then crashed, ruining the speculative investors who had bought them. But the Bitcoin phenomenon is more than a bubble. The scale of the recent boom-and-bust has been staggering indeed. Such monumental appreciation and volatility are clearly the result of speculation — people buying the online currency just because they think its value will rise, not because they want to use it to purchase goods and services.

Amazon’s new “virtual currency” of dubious benefit to customers Straight from Amazon's press room comes the news that Amazon has officially launched Amazon Coins, which the company excitingly claims are "a great way for customers to save money when they buy apps, games and in-app items" for Kindle Fire users. To help everyone start using Amazon Coins, Amazon has deposited 500 of them into the accounts of all existing and new Kindle Fire users in the US. Amazon Coins were initially announced back in February, with the company saying they're primarily designed to benefit developers and consumers. "For customers, Amazon Coins is an easy way to purchase apps and in-app items on Kindle Fire, and for developers it’s another opportunity to drive traffic, downloads and increased monetization," proclaims this morning's press release. The biggest problem is the inevitable misalignment between "coins" purchased and "coins" used. From Amazon's perspective this is fabulous.
