Data objects are different than physical objects. Data files can be fragmented and distributed across storage locations, then re-assembled instantly as needed. Even on my laptop, files are stored in different parts of a hard disk (or flash drive) as fragments. Networks of personal computers can also host distributed file fragments. The most recent innovation…More

History is my witness
Independent Russian news website Meduza has operated in Latvia since 2014. It aims to provide independent reporting and commentary about Russia for Russians. It is inevitably critical of Putin’s government. Since launching its attack on Ukraine the Russian government blocked Meduza in a raft of measures to silence criticism. Meduza is blocked from its main…More
Greening the blockchain
While the 2021 United Nations Climate Change Conference COP26 takes place in Glasgow this week, attention turns to the energy waste of cryptocurrency transactions. A substantial part of the cost resides with the “proof of work” (PoW) process by which validating nodes on a blockchain compete to solve a numerical puzzle the solution to which…More
CryptoArt 101
Now that the worth of my Bitcoin wallet has risen to double figures (in £s) I’m ready to invest in some digital art. Digital artworks are static or moving digital pictures, such as animated GIFs, though the category could include any digital asset: video, sound file, music score, computer code, 3D computer model, etc. In…More
Digital cash 101
Bitcoin is a cryptocurrency, i.e. it is digital money that purportedly carries some of the benefits of cash. You can buy things with it, give it away, invest it, and stash it without involving a bank. But unlike cash, there’s no physical paper or coinage. You could try to design your own banknote, or make…More
Pseudo-crypto currencies
I heard about onecoin through the BBC Podcast called The Missing Cryptoqueen by journalist Jamie Bartlett and producer Georgia Catt who investigated the scheme and the damage it has wrought to individual lives. As I listened to the first episode of the podcast I thought I was hearing a mockumentary, or a mystery story in…More
No interpreter required
If only people speaking different languages could communicate without the need of an interpreter. I’m thinking of the Trump-Putin encounters with translators present. Only unscrupulous leaders would bar their translators from disclosing to other trusted officials what was said. But I’m also thinking of Leon Battista Alberti’s justification of his cipher technique, which was to…More
Cooperation and complicity
The Barras is a market in Glasgow that is (or was) notorious as a site for hustlers. It attracts both bargain hunters and spectators. Ten years ago a group of us conducted a study of the area, mainly to consider its soundscape. On more than one visit we observed a familiar scenario involving the sale…More
Challenges of the sharing economy
Architectural Research Quarterly just published an article by Tolu Onabolu and me called “Blockchain for architects: Challenges from the sharing economy.” Our tagline is: “Cryptocurrencies, blockchain technology, and other aspects of the sharing economy offer benefits and challenges for architecture. They also furnish metaphors about urban living.” The article derives from speculations in this blog…More
What’s wrong with the sharing economy
The so-called sharing economy has come under a lot of criticism lately. Think of the apparently (almost) unregulated and unfair practices surrounding Uber, the global car hire (taxi) firm that designates its drivers as self-employed. Passengers like Uber. Once subscribed, you book a car and driver via your smartphone. You track your nearest available ride…More
