1. Security

Aspect	Traditional	ZKP
Credential Exposure	Password sent over wire (HTTPS mitigates).	Secret never leaves client—proofs only.
Server Breach	Hashed passwords stolen → Offline cracking (bcrypt slows this).	Stored hash stolen → Useless without secret (preimage resistance).
Replay Attacks	Mitigated by tokens expiring or nonces in OAuth.	Nonce per proof—replay blocked.
MITM	HTTPS protects; plaintext password risk if TLS fails.	HTTPS still needed; proofs leak less info.
Trusted Setup	None—simple crypto (SHA, bcrypt).	ZK-SNARKs need trusted setup—leak risks forgery.
