I reread the Bitcoin paper yesterday, so with my newly refreshed knowledge id find the nearest mathimation, explain it to them, implement the protocol with paper records, handwritten hashes, and messages on horseback or something. After a few years when every major economic power realizes how valuable a deflationary currency that Mansa Musa doesn’t control (14th century african gold-salt bazzilionare, ~400 bill USD today), the price of my currency would increase vastly, making me super rich.
