Mark Frauenfelder: A Typical Day in a Blockchain-Enabled World Circa 2030

Let’s follow Crowley the Crocodile as he goes about his day in the year 2030, from the moment his bitcoin-powered bioalarm clock wakes him, until he eats his late night pizza ordered using a rating service that runs without human owners.

A blockchain is an online database that stores information across a network of personal computers, making it not just decentralized but distributed. This means no central company or person owns the database, yet everyone in the network can use and help run it, but not tamper with it.

The most popular use of blockchain technology today is bitcoin. The bitcoin blockchain manages around 200,000 bitcoin transactions a day, moving the equivalent of US$150 million around the world without the need of banks or other financial intermediaries.
