Inside Bitcoins

Electronic money is not a new idea. The Electronic Fund Transfer Act was passed by the U.S. Congress and signed by President Jimmy Carter 35 years ago (1978). Other forms of electronic money include payment processors, direct deposit, and digital currencies such as Bitcoin. What distinguishes Bitcoin from other electronic money is that it is a cryptocurrency... Will Bitcoin replace the dollar, euro, yen, franc, kroner, et al? Possible, but most authorities seem to be saying it is doubtful. more

Breaking the Mold: Reclassifying Over a Billion .XYZ Domains for Alternative Uses

Three years ago, my team and I launched .xyz with the mission of bringing competition, choice, and innovation on the internet. .xyz was probably the only domain extension that had no built-in meaning, included very few domains priced at a premium, and relied on low margins and high volume. We brought with it the message that .xyz was for every website, everywhere. And instead of targeting one vertical, we connected with the next generation of internet users... more

Are Blockchains the Most Expensive Database Ever Invented?

One of the oft-made claims about Bitcoin and its blockchain transaction ledger is that they make transactions really cheap, so you can pay someone anywhere in the world for free, or close to it. But when you look closer, is that really true? Not by a long shot. Bitcoin transactions are stored in a large shared database called the blockchain. more

Liberty Reserve Now, Bitcoin Next?

The papers have been abuzz with the shutdown of Liberty Reserve, an online payments system, due to accusations of large scale money laundering via anonymous transactions. Many people have noted similarities between LR and Bitcoin and wonder whether Bitcoin is next. I doubt it, because with Bitcoin, nothing is anonymous. more

Bitcoin: The Andromeda Strain of Computer Science Research

Everyone knows about Bitcoin. Opinions are divided: it's either a huge bubble, best suited for buying tulip bulbs, or, as one Twitter rather hyperbolically expressed it, "the most important application of cryptography in human history". I personally am in the bubble camp, but I think there's another lesson here, on the difference between science and engineering. Bitcoin and the blockchain are interesting ideas that escaped the laboratory without proper engineering - and it shows. Let's start with the upside. more

The Great Forking Bitcoins of China

Let's say I'm with the Chinese government and decide that I am tired of people evading currency controls and money laundering using Bitcoin. So we adjust the Great Firewall of China to block port 8333. We also add some proxies that allow some uncleared transactions from outside to flow into Chinese networks but not the other way and keep track of which ones we let through. Since a large fraction of the miners are inside China, and all of the hard currency exchanges are outside, this will cause a pretty serious fork. more

Blockchain Technology Can Solve Some of Africa's Problems

Lately, the word blockchain is gaining a lot of attention from businesses, investors and governments, especially around how it could transform how we do business today. As the world looks up to Blockchain technology for radical transformations in many industries and sectors, I want to take a look at how it could help governance in Africa.
The African continent is plagued with corruption, bad governance, mismanagement and lack of accountability. more

The Top 10 .Brand Moments of 2017

Each year in December, I sit down and take a moment to reflect on how the .brands space has progressed in the previous 12 months. Most folks will understand that starting a movement to create the next evolution of the internet with 'digital superbrands' was a little slow at first. Slowly but surely, that has started to change and especially in 2016, it really felt like people were starting to 'get it' -- both in terms of brands themselves, and the media and consumers. more

Why Bitcoin Will Not Solve the Caribbean's Financial Inclusion Woes

There's a deluge of hype around Bitcoin and blockchain technologies right now, and policymakers and regulators in the Caribbean are doing their best to wrap their heads around the advantages and disadvantages of this virtual currency. Similar questions are being contemplated in the ICTs for development (ICT4D) community, taking into account that electronic money (e-money) platforms such as Safaricom's M-PESA have essentially solved the financial inclusion quandary for millions of people in Kenya. more
