Well, call it what you want, but our HOA just replaced the perfectly good paper ledger for the neighborhood pool schedule with some newfangled 'blockchain technology.' So now, instead of just signing your name, you need an app with a digital key to book a lane. How’s that common sense? A simple paper list never got hacked, and my 70-year-old neighbor can’t even get in for her morning swim because her phone ‘isn’t synced.’ We’re solving problems that don’t exist again.
