Vitalik: ETH addresses have "statefulness", which is a key difference from "pure encryption"

Vitalik Buterin, co-founder of Ethereum, wrote on X platform that thanks to zkemail, tlsnotary, anon aadhaar, any form of identity verification can be converted into an ETH address and then inserted into other tools (such as multi-signature, DAO authorization, etc.). One key difference between ETH addresses and "pure cryptography," which is also where blockchain provides its value, is that ETH addresses can have "statefulness," so details such as key revocation can be abstracted.
