Offline Protocol is built with security-first principles, ensuring confidentiality and trust even in hostile environments.

Core Security Features

End-to-End Encryption

AES-256 encryption secures all messages.

ECC Key Exchanges

Lightweight, secure session establishment using elliptic curve cryptography.

Public/Private Key Pairs

Keys are never transmitted—only generated and used locally.

Zero-Knowledge Proofs

Validate actions without revealing sensitive data.

Fraud Prevention

Replay Attack Protection

Unique message signatures prevent duplication or tampering.

Device Authentication

Lightweight cryptographic challenges secure relay nodes.

Merkle Tree Structures

Enables efficient, tamper-resistant transaction validation.

Consensus on Reconnect

Local transactions automatically sync globally once internet access returns.
