It combines messaging, voice calls, file sharing, crypto wallet functionality, and Mini Apps in a single, cross-platform experience - with Post-Quantum Cryptography (PQC) and no central servers. Unlike traditional messengers that rely on central servers to store keys and mediate authentication, Spixi users hold and control their own encryption keys locally . Every conversation is uniquely encrypted, and identities are proven cryptographically without passwords, central accounts, or third-party trust. --- 🚀 Why Spixi? ⚛️ Post-Quantum Resistant Security - Hybrid key exchange ( RSA + ECDH + Kyber/ML-KEM ) ensures confidentiality even against future quantum threats. 🔒 True End-to-End Encryption - Dual encryption (AES + ChaCha20-Poly1305). Keys never leave the user's device, and each contact-pair uses unique cryptographic keys. Only the sender and intended recipient can ever decrypt a message. 🧬 Self-Authentication, Not Server Authentication - In centralized systems, a username and password authenticate you to a server, which then manages or even stores your keys. In Ixian, your cryptographic address is your identity , and you sign messages yourself with your private key. No servers vouch for you - your identity and communication security are entirely under your control. 🕸️ Decentralized by Design - Runs peer-to-peer over Ixian's DLT and S2 overlay network .
