The Blockchain Gang, Part 3

Columnist: Michael E. Duffy
Feb, 2018 Issue

For the past two months, I’ve been writing about cryptocurrencies like Bitcoin, so-named because the blockchain technology that underlies them is based on cryptography (encoding data so that only people with the proper keys can read it). Bitcoin and other cryptocurrencies like Ether and LiteCoin work like cash, in that they are anonymous.

The Blockchain Gang Part 2

Last month, I introduced the idea of “distributed ledger technology,” which is another name for the blockchain, a way of accounting for transactions without a central trusted authority. The most well-known public blockchain is associated with the Bitcoin digital currency, and is used to keep track of transactions of that asset without a central bank.

The Blockchain Gang

There’s a lot of hype around blockchains these days. It all started with Bitcoin—a form of digital currency, which doesn’t require a central bank to operate. Bitcoin is like cash: it’s anonymous, and using it carries no transaction fees (unlike credit cards). Bitcoin (and to a lesser extent other digital currencies) has grown in popularity since that time, and increased in value. If you had bought a single Bitcoin in June of 2013, you would’ve paid $128.10. On October 1 of this year, that same, single bitcoin was worth $4,280.11, a 3,300 percent increase. (Bitcoin has been around since early 2009. In late 2009, the first exchange of real dollars for Bitcoins valued a Bitcoin at about 10 cents.)
