Not all crypto transactions. Some blockchains effectively use advanced cryptography to obscure sender, recipient, & amount beyond any known methods of revealing them. Zcash & Monero are the leaders here. Zcash, used with its fully ‘shielded’ addresses, is theoretically strongest; Monero probably enough against most realistic threats – but maybe a very-deep-pocketed nation-state could decode some flows. But neither creates an ‘open Venmo’ or Bitcoin-like full public record of payers/payees/amounts for casual analysis by anyone. [Disclosure: I’m a compensated advisor to the company, now a nonprofit, that initially launched Zcash.]
