Vitalik: The "statefulness" of ETH addresses is a key difference from "pure encryption"

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