David Chaum invented blind signatures in 1982 — a cryptographic trick that lets a bank verify a coin without knowing who spent it. His DigiCash system in the 90s was functional, private, and decades ahead of its time. Banks licensed it, then quietly let it die. How much of our digital future was buried not because it failed technically, but because it succeeded politically?
