Using a pseudonym, which is a fictitious name or alias. Pronounced "soo-
don-a-miss." For example, cryptocurrency transactions are pseudonymous because the aliases are the sender and recipient's public keys, not their names. However, if someone is able to match a public key to a person's name, then all the transactions ever made by that person are visible. Contrast with anonymous, which means nameless. See
