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

Why Is It So Hard to Run a Bitcoin Exchange?

One of the chronic features of the Bitcoin landscape is that Bitcoin exchanges screw up and fail, starting with Mt. Gox. There's nothing conceptually very hard about running an exchange, so what's the problem? The first problem is that Bitcoin and other blockchains are by design completely unforgiving. If there is a bug in your software which lets people steal coins, too bad, nothing to be done. 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 Solution to Financing Smart Cities?

One of the most difficult elements in the development of smart cities is how to finance them. Local government doesn't have the money for it and while state and federal governments might have more money to spend there is no way that their current tax funds could pay for even a fraction of the investments that are needed. Indeed the reality is that in order to create a smart city... massive up-front investments are needed. more

What Do Bitcoin, Cloud Computing and the New gTLDs All Have in Common?

I am a student of life, learning one hard lesson at a time. In fact, I actually dropped out of my last year of college to start a tech company in a new space called the internet. I was an entrepreneur running an online service prior to the advent of the world wide web in 1992, back when Pine, Usenet, and Gopher ruled the information superhighway. Over the last 25 years, I have learned a great deal about technology adoption cycles by launching six internet companies, each at the forefront of a new technology wave. more

Thoughts on the Open Internet - Part 5: Security

Any form of public communications network necessarily exposes some information about the identity and activity of the user's of its services. The extent to which such exposure of information can be subverted and used in ways that are in stark opposition to the users' individual interests forms part of the motivation on the part of many users to reduce such open exposure to an absolute minimum. The tensions between a desire to protect the user through increasing the level of opacity of network transactions to third party surveillance, and the need to expose some level of basic information to support the functions of a network lies at the heart of many of the security issues in today's Internet. more

Blockchain of Things Goes Global at ITU-T Dubai Meeting

Today, one of the world's largest Internet companies, Alibaba, together with a compelling array of other providers, vendors, and government bodies for the first time called for a visionary multilateral technical and operational "framework for a Blockchain of Things." The exceptionally thorough and comprehensive 23-page document, SG20-C.008, was submitted into the upcoming ITU-T SG20 Internet of Things (IoT) Study Group meeting at Dubai, 13j23 March -- the first group gathering in the organization's new 2017-2020 study period. 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

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

The Great Domain Correction of 2017?

There were only 1.8 million registered .com names when I joined the NSI (Network Solutions) Marketing Team in the summer of 1998. ICANN was formed just a few months later. By the time we were acquired by Verisign in June of 2000 there were roughly 14 million names in the .com database. I recall predictions that one day there would be 100 million registered .com names. Some thought that was a craaaazy number and wanted to know what we were smoking. 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
