Romancing the blockchain
The blockchain idea is addictive for some. It’s technically fascinating, mysterious and counter-intuitive. It depends on cryptography to function, and inherits the fascination many of us have with cyphers and codes. Who can resist the lure of a secret message? The way blockchain platforms function also mystify with their abstruse methods and terminology: proof of … Continue reading
Architecture and espionage
The Spy Museum near Potsdamer Platz in Berlin features cumbersome cold-war surveillance and bugging devices, and retells the story of spying and secret communications dating back to Ancient Egypt. Architecture is always there as a stage setting for covert operations. After all, spies inhabit the shadows. I recall from previous reading that Odysseus disguised himself … Continue reading
The death of a public life
You can be excused for thinking that social media presents imperfect insights into human nature. US political comedian Bill Maher excoriated the public personas social media users present online — their polite, politically correct, family-friendly, “prissy” avatars, whose great “super power” is that they remember birthdays! “If you want to know who someone really is … Continue reading
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 … Continue reading
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 … Continue reading
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 … Continue reading
Encrypted city
Urban metaphors are powerful in the world of computing. The reverse is also true. Computing brings metaphors to bear on how we think of cities — as flows of data, networks, circuits, grids and an Internet of things, as if cities are made up of bits, memories (RAM), sensors, actuators, and with communication systems, inputs, … Continue reading
Share city
In his book on the “sharing economy,” Arun Sundararajan maintains that commerce is shifting “away from traditional corporations and toward a crowd of entrepreneurs we find through a digital marketplace” (6). Within the constellation of these new (shared) business models he places Airbnb, a platform that allows individuals to capitalise on their own under-utilised domestic … Continue reading
How smart are smart contracts?
Blockchain technologies such as bitcoin, support peer-to-peer monetary transactions, where lines in a shared ledger indicate payer, payee, date, amount and the goods or services to be exchanged: as is the case in a line in a bank statement. But, instead of a text line indicating the product being exchanged, what if that line included … Continue reading

How do signatures function? A signature is a sign, seal, or mark on a document indicating its authenticity, as when a painter signs a painting, or someone signs a letter or legal document. The signature and the thing it marks is meant to be a one-off. The signature marks an original document, before the thing … Continue reading
