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

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

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

Kelly's Case Updated: A Need for Further DNS Registrar Industry (Self-)Regulation

After ten hectic days, the young Clemson civil engineer turned MBA entrepreneur -- who turned a passion for helping equestrians care for their horses into a website enterprise -- had the HorseDVM.com domain, and its IPR returned to HorseDVM LLC. Ultimately, however, it was the registrant who realized the registrar had wrongfully sold him the domain and the unfairness of what had occurred, who facilitated the return. The culpable registrar ultimately did nothing but unfailingly support its auction subsidiary's sale... more

What Does Blockchain Have to Do With Voting?

Apropos of recent news stories about a blockchain-based voting system that was hacked before its first election, someone asked: "Perhaps final recognition that a lot of blockchain is hype? Or simply an interesting side-story?" A blockchain can ensure that the lies you see are the same lies that were published, but that doesn't have much to do with voting. more

Thoughts on Libra

I worry that Libra's financial inclusion might come with an attendent loss of privacy or autonomy. After months of speculation, Facebook on Tuesday announced Libra, a cryptocurrency with the mission of enabling a simple global currency and financial infrastructure that empowers billions of people. more
