😉 💯 yup. in 1983, David Chaum (cryptographer) published a conference paper "outlining an early form of anonymous cryptographic electronic money." he developed proto-crypto currency called ecash in 1995. then Nick Szabo came out with Bit Gold (precursor to btc) in 1998 but couldn't figue out the double spend problem. a decade later on Oct, 31, 2008 Satoshi Nakamoto published the #Bitcoin whitepaper and the first established #cryptocurrency, #BTC which would not be possible without #blockchain tech
