Quantum International Corporation Launches GhostLine - A Serverless, End-to-End Encrypted Messenger for Truly Private Communication

Denver, Colorado--(Newsfile Corp. - November 15, 2025) - Quantum International Corporation (OTC: QUAN) today announced the launch of GhostLine, a groundbreaking private messaging platform that operates entirely in the browser - requiring no downloads, accounts, or central servers. With GhostLine, two users can connect directly using secure, one-time connection codes to exchange end-to-end encrypted text, images, and voice messages that disappear without a trace once conversations end.

"Privacy should be effortless," said the CEO of Quantum International Corporation. "GhostLine demonstrates that users can enjoy real-time, encrypted communication without centralized systems or personal data exposure. When a conversation ends, it's gone - forever."

Technology and Innovation

GhostLine sets a new standard for lightweight, secure, and ephemeral communication through several key innovations:

• Serverless Architecture: GhostLine runs as a fully static web application. All messages travel directly between users' browsers over encrypted peer-to-peer connections - no message storage or third-party servers.

• One-Time Connection Codes: Users connect securely using short alphanumeric or QR codes, without revealing personal information.

• End-to-End Encryption: Each session uses ephemeral keys generated with modern cryptographic standards (ECDH P-256 and AES-GCM).

• Ephemeral Messaging: Messages and images self-destruct after a user-defined timer or upon being read, leaving no residual data.

• Identity Verification: Users can confirm the authenticity of their connection via a simple safety fingerprint.

• Encrypted Voice Calls: GhostLine supports direct, private voice communication over the same secure channel - right from the browser.

Designed for Privacy-First Users

GhostLine serves individuals and professionals who need temporary, secure, and anonymous communication, including:

• Journalists, investigators, and researchers conducting confidential exchanges.

• Professionals and consultants handling sensitive or regulated information.

• Teams managing short-term projects that require non-persistent communication.

• Individuals seeking private, ephemeral conversations without data trails.

Availability

GhostLine will be available worldwide beginning November 15, 2025. The platform runs entirely in modern web browsers - no installation or registration required.
