Encrypted is not enough. The metadata matters too.
The question you should ask any secure messenger is not only ‘can someone read my messages?’ but ‘can someone prove who I talked to, and when?’ Zbelthas Chat is built around that second question.
Zero metadata
Even encrypted messengers usually leak who talks to whom and when. Zbelthas Chat is designed so that information does not exist on our side — not stored, not logged, not knowable.
Glossary: zero metadata →Perfect forward secrecy
Every message gets its own short-lived key, negotiated with ML-KEM. If one key is ever compromised, past and future messages remain safe.
Glossary: pfs →No phone, no email
You connect with a cryptographic identity you control. No SIM swap, no email account takeover, no "verify with SMS". Your social graph is yours.
Glossary: sovereign id →ZeroMetadataMessaging
Communication that leaves no trace. Every message encrypted before it leaves your device, decrypted only by the intended recipient. No central servers to subpoena, no metadata to analyze, no phone number required, no backdoors to exploit.
What is zero-metadata messaging? Traditional apps store who you talk to, when, and how often — even if messages are encrypted. Zbelthas stores nothing. No contact lists, no timestamps, no read receipts. If it doesn't exist, it can't be subpoenaed.
No server ever sees plaintext. No metadata is logged.
Mathematically unbreakable forward secrecy
Every message encrypted before it leaves your device using a fresh ephemeral ML-KEM key. Compromising one session key reveals nothing about past or future sessions — mathematical guarantees, not promises.
Past sessions stay private
Ephemeral keys are deleted immediately after use. Even a full device compromise cannot decrypt previously sent messages.
No behavioral fingerprint
- No message timestamps stored
- No contact list on servers
- No read receipts logged
- No typing indicators transmitted
No central servers to attack
Messages route through a distributed P2P network. No single server stores your conversations — even temporarily. One subpoena, one hack, one rogue employee — none of it can expose what was never stored. No subpoena can retrieve what doesn't exist.
No phone number
Cryptographic identity derived from your keys. Your identity permanently linked to a key pair — not your phone number. No personal information required to create an account or start communicating.
Messages that disappear
Set per-message or per-conversation expiry. Deletion is cryptographic — not just a UI toggle. The key is destroyed; the ciphertext becomes meaningless.
Mathematically impossible
The architecture makes backdoors structurally impossible. If a backdoor exists for one, it exists for all — including hackers and hostile nations. We chose mathematics over compliance theater.
