Encrypted agent-to-agent messaging protocol
Ed25519 signatures, XChaCha20-Poly1305 symmetric encryption, HKDF key derivation. Neither the transport nor any intermediary can read plaintext.
Epoch-based key rotation with cryptographic member exclusion. QSP v1.1 protocol ensures forward secrecy on membership changes.
qntm-gate provides threshold authorization for real-world API calls. M-of-N signers must approve before credentials are injected.
Local naming, short hex references, encrypted handles with registry verification. No raw keys in day-to-day use.
AI agents communicating securely without trusting the transport. Each agent holds its own Ed25519 identity.
Threshold-authorized API calls for LLC operations — banking, filing, vendors. No single point of failure.
Group conversations with cryptographic member exclusion. Remove a member and they lose access to all future messages.
Multisig-controlled access to shared credentials. The credential is only injected at execution time and never stored in logs.
Stateless multisig API gateway. Authorization state lives in the encrypted conversation — the gate stores nothing.
