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
Crypto-conspiracy
CryptoArt is a term applied to artworks that are bought, sold and authenticated on a blockchain. In this sense, CryptoArt is no more a genre, sub-genre, style or movement in art than auction art, gallery art or collectible art. “Art” is not a protected or regulated noun and invites appendage to many other nouns. A … Continue reading
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 … Continue reading
Beyond averages: DCT graphics
The visual field is full of smooth curves. Shadows don’t have sharp edges but fade out. Colours blend, sometimes imperceptibly. At some level of detail, most things transition smoothly, but to varying degrees. The variation across such transitions is noticeable in a high quality digital photograph, i.e. a pixel image. Here is a random row … Continue reading
What a calamity!
Calamity, cataclysm, catastrophe, crisis, catalysis and cacophony bear no common etymology as far as I can see, though they sound as though they should. A calamity derives from the idea of a corn harvest gone bad. A cataclysm is a deluge. A catastrophe is an overturning. A crisis is a moment of decision. A catalysis … Continue reading
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 … Continue reading
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 … Continue reading
Sociable encryption: The secret of the five keys
Will encryption save us? Social psychologist Shoshana Zuboff explains in detail the methods employed by Google and other digital giants to track our clicks, sell our data, and auction targeted advertising slots to monetise our private on-screen experiences. Our online behaviour is the resource. We are the product, not the consumer. Google’s clients are advertisers … Continue reading
Nested parentheticals
Sometimes it’s hard to get back on track. People tell stories and construct arguments with subplots and digressions. It’s fine for stories to wander. But for coherence we expect the story-teller to return to the main point, to rewind the string they just unravelled back into a neat ball. One of Trump’s improvised speeches illustrates … 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
