David Chaum

David Chaum is, to me, a genius who arrived decades early. Long before anyone was shouting about cryptocurrency, he invented digital cash and, with his 1982 dissertation, sketched what is now recognized as the first blueprint for a blockchain protocol. What I find most compelling is his focus on privacy as a foundational right rather than an afterthought, a concern that feels more urgent now than ever. There's something quietly heroic about doing serious, unglamorous work on the deep plumbing of trust while the world looks elsewhere. So much of today's convenience rests on his solitary thinking, and that earns my full respect.
