Here are three pieces that have been open in my browser for a few days now, while I kept postponing the urge to write something substantial about each of them. Instead, I’ll simply present them for your consideration, with a paragraph or two on selected areas of possible interest.
First, Bruce Schneier on blockchains, and how it’s debatable that they live up to what many consider one of their key promises: to “displace, reshape, or eliminate trust“. Schneier is an American cryptographer who has written extensively on security issues (his work on airport “security theater” is well-worth reading), and he certainly speaks with authority, even if you might not agree with his analysis.
