What is Threema?

Threema is an instant messaging app designed with a strong emphasis on minimizing user data collection. The platform ensures that all communications are shielded by end-to-end encryption, safeguarding user privacy at every turn. During the initial setup, users generate a unique Threema ID and have the choice to link a phone number or email address if they wish. Unlike numerous free messaging apps that depend on user data for ad revenue, Threema follows a paid subscription model, deliberately avoiding the collection of any personal information. In stark contrast to services like WhatsApp, which gathers metadata that can jeopardize user privacy, Threema places a high priority on maintaining confidentiality. The app includes options to conceal sensitive conversations, securing them with a PIN or biometric authentication for added safety. Users can also engage in calls without revealing their phone numbers, thus ensuring that these voice communications remain secure due to the robust end-to-end encryption. Furthermore, Threema is known for its exceptional quality in voice and video calls, which significantly enriches the overall user experience. As a legitimate Swiss company, Threema operates its servers from Switzerland, which provides a strong framework for data protection. All development and customer support activities are handled in-house, showcasing a dedication to quality and user privacy. Moreover, Threema fully adheres to GDPR regulations, further solidifying its commitment to safeguarding user rights and data. This comprehensive approach to privacy and security makes Threema a compelling choice for individuals who prioritize their digital safety.

What is Solarium?

Solarium functions as a fully decentralized, encrypted messaging platform that is resistant to censorship, leveraging the capabilities of the Solana blockchain. Currently, it is in its alpha stage, operating on the Solana developer network. Each message sent through Solarium is protected by end-to-end encryption, using the XChaCha20-Poly1305 symmetric encryption algorithm, which relies on a shared 256-bit content encryption key (CEK) for all communications within a defined channel. Notably, the messages themselves are not directly signed; instead, when the data is decrypted, it does not reveal any sender identification. The sender's signature is associated with the blockchain transaction that integrates the message into the channel, thereby maintaining user anonymity. This innovative design not only prioritizes user privacy but also underlines the platform's dedication to secure and confidential communication, paving the way for a new standard in digital messaging. As the platform evolves beyond its alpha phase, it aims to introduce additional features that further enhance security and user experience.
