The Ever-Evolving Problem of DNS Abuse

For several years, many within ICANN circles have raised concerns about the escalating nature of domain name system (DNS) abuse. While some strides were made toward a safer DNS, new data - this time from a comprehensive study of DNS abuse by the European Union - demonstrates that abuse remains a frustratingly obstinate problem that requires urgent attention. We've seen some registries and registrars testing innovative industry-led initiatives in an effort to address the issues. more

Blockchain’s Two-Flavored Appeal

A recent story in Medium describes yet again quite well why blockchains don't solve any real problems: Blockchain is not only crappy technology but a bad vision for the future. So what is their irresistible appeal? Bitcoins remind me of a story from the late chair of the Princeton University astronomy department. In 1950 Immanuel Velikovsky published Worlds in Collision, a controversial best-selling book that claimed that 3500 years ago Venus and Mars swooped near the earth... more

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

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

Web3 - What Brand Protection Pros Need to Know

Avivah Litan, the storied Gartner analyst, laid it down succinctly for insiders in her blog two and one-half years ago. She said, "Web 3.0 will transform us from Web 2.0's monetization via surveillance capitalism and advertising to monetization built directly into the protocol that is equally available to any connected user." Translated, that means we'll control our destiny by owning and managing our credentials for logging into systems, content, financial resources, and, importantly, our data. And, we are told, blockchain technology will enable all that. more

Internet Governance Outlook 2020: The Next Generation of Players and Problems Is Coming

The beginning of a new decade is always an invitation to have a broader look into the future. What, in the next ten years, will happen in the Internet Governance Ecosystem? Will the 2020s see the usual swinging pendulum between more liberal and more restrictive Internet policies in an interconnected world? Or will we move towards a watershed? more

Hackers Hijack DNS Server for Cyrptocurrency Wallet BlackWallet, Over $400K Stolen From Users

Unknown hackers (or hacker) have hijacked the DNS server for BlackWallet.co, a web-based wallet application for the Stellar Lumen cryptocurrency (XLM). more

Protecting Your Brand in the New World of NFTs

Months ago, while watching a Saturday Night Live skit about non-fungible tokens (NFT) featuring a parody of Janet Yellen speaking to a high school economics class, I realized what an NFT is and how they work. What they represent, how they are minted, and how their value is exchanged became clear while watching Pete Davidson in a boy wonder unitard rap about the latest crypto-phenomena. It was only later that I realized that NFTs have plenty of practical applications. more

There Is No Artificial Intelligence

It seems like most new technology today comes with a lot of hype. Just a few years ago, the press was full of predictions that we'd be awash with Internet of Thing sensors that would transform the way we live. We've heard similar claims for technologies like virtual reality, blockchain, and self-driving cars. I've written a lot about the massive hype surrounding 5G -- in my way of measuring things, there isn't any 5G in the world yet, but the cellular carriers are loudly proclaiming its everywhere. more

A New Project Called Handshake Wants to Decentralize DNS, Says It’s Unlike Previous Attempts

An entity called the Handshake Network claims its newly developed open source project offers advantages over the traditional naming and signature systems. more

The .BEST New gTLD: Second Interview

This is a one hour podcast giving all details about what the .BEST social network is going to be and how users will be able to generate an income from it... Cyril Fremont gives lots of details on how his social network, focusing on reviews, is going to be different from Google Reviews, Facebook, Yelp and TripAdvisors. If one would be tempted to think that ... well, "that's just going to be another social network", then, I strongly suggest to listen carefully the part of the interview on the decentralization of this network. more

Is Blockchain Causing More Cybersecurity Attacks in the Financial Industry?

There's a lot of misunderstanding about blockchain. A recent study by HSBC, for example, found that 59 percent of customers around the world had never heard of it. Yet, while that alone is quite telling, it's probably more alarming to consider the fact that very same poll revealed that 80 percent of people who had hard of blockchain did not understand what it is. This level of confusion isn't confined to the general population either. 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
