Obsidian Secure Messenger (OSM) client
Our flagship application, The Obsidian Messenger, is scheduled for a beta release on Android, 24th December 2017. Learn more about our upcoming release!
Obsidian Platform is looking to help foster startups that seek to develop applications or services that focus on data protection and user privacy.
Obsidian Platform only works with organisations that share our philosophy that want to do good, by helping others. We advocate for data protection and privacy for every human being.
We actively open source all our technology whenever possible. We also plan on organising free hackathons and meetups to help push for a world where the best technologies can be built and evolved together.
Getting started with Obsidian is as simple as downloading a Wallet (available for Linux, Windows and Mac OS). We offer supporting documentation through our Github Wiki.
Our most recently published white paper, “A Decentralised Messaging and Payment Protocol”, lays out our vision for how Obsidian will enable users to send money like messages, and send messages like money. Building on the ideas presented in our ICO white paper, it also lays the foundation for two upcoming documents.
The ObsidianXXL is a dashboard that is actively being developed and is currently available as a beta to download! This dashboard can be used by anyone on the network to easily view your running node information remotely.
A concise overview of the Obsidian opportunity: the problems we’re addressing, the technology we’re using, and the benefits to those willing to invest and trade ODN coins on the crypto-markets.
Obsidian enables the most secure digital conversations, without requiring user accounts or phone numbers that could involuntarily reveal your identity or messages now or in the future. This is increasingly important.
- For Everyone – to obtain a high quality of communication, without self-censorship
- When Journalists talk with sources securely
- Enabling free scientific collaboration
- For ordinary people in non-free countries, to build a civic society
- To help environmental activists and whistle-blowers expose malpractices
Obsidian advances state-of-the art applied cryptography, providing an edge over currently feasible and future attacks.
- Applies best-in-class and less common hashing algorithms such as BCrypt with 2n rounds, SHA256 and SHA512 in combination for slow and entropy-preserving key derivation, to protect against the use of rainbow tables and against brute-force and dictionary attacks on passphrases.
- Uses pure 256 Bit random keys and 128 Bit seeds on compressed message payloads, together with multiple AES 256 Bit encryption rounds, to make enigma-style known plaintext attacks slow and practically infeasible – providing quantum-computing secure symmetric encryption.
- Uses advanced Elliptic Curve Cryptography developed by Daniel J. Bernstein and Tanja Lange, to provide unparalleled security for ephemeral Diffie-Hellmann key exchange.
- Uses 128 MACs to protect against man-in-the-middle attacks and message authentication.
In the physical world, we are used to enjoying anonymous communication in public places: to freely exchange ideas and opinions with people we’ll never see again. Obsidian brings anonymous communication to instant messaging.
- Obsidian is the only messenger that doesn’t use your phone number or ever accesses your address book.
- Obsidian allows you to create 10-digit one-time Identities, which you can backup and restore, or delete forever.
- Obsidian Identities cannot be reverse-searched, as can be the case for phone numbers or email addresses.
- When you lose your device, your Obsidian Identity and those of your contacts are encrypted (like all messages, pictures and files), and cannot be uncovered without entering your passphrase.
- Decentralised Obsidian messaging nodes are to be run globally by the community, and are much to difficult to target for surveillance compared to a single company.
Obsidian is designed to be an app for daily use: emphasising constant privacy rather than the occasional desire not to share.
- Send all message types with delivery and read receipts.
- Send text, pictures, recorded video and audio, and all types of files.
- Export and decrypt all types of sent and received files.
- A password, protected with special brute-force protection, is needed to start Obsidian.
- Your Obsidian app data folder is 100% encrypted for your safety, providing peace of mind for when you lose your device or when using services like iCloud backup.
- Give yourself and your contacts creative names and profile pictures, without regret – they’ll never be shared, they are encrypted on your device and are just there to make your world pretty!
- Undelivered messages are dropped after 7 days by the network and by default, all data older than 30 days is deleted on the device to reduce possible damage should security ever be breached.
- Obsidian doesn’t offer audio or video calls. Both are only possible with encryption that is an order of magnitude less secure, and that can be broken – disclosing IP addresses and thereby location to both communication partners.
The Obsidian messaging app will receive platform integrations while remaining true to its concept of a privacy sandbox.
- The Obsidian messaging app will be integrated with the Obsidian ODN wallet, to allow for ‘sending money like messages’ in a seamless experience.
- Provide an anonymous bot API for the Obsidian network, to allow private user-to-bot communication, e.g. to query services like medical expert systems.
- The bot API targets 3rd parties to offer services on the Obsidian network for free and against payment in ODN.
- The app will integrate with the decentralised Obsidian messaging nodes, rewarding them for transport – while still allowing a free quota of messages and keeping the Obsidian blockchain free from traces of messaging traffic.
Obsidian is currently in development for Android, iOS and Windows 10. Obsidian is designed for use with smartphones, tablets and PCs.
- A first Android release of Obsidian v. 1.0 is expected to be released on December 24th 2017.
- Obsidian v. 1.0 will offer 75% or more of the features described in this section.
- First versions for iOS and Windows 10 will be released in Q1 2018.
- The source code of the Obsidian messenger is currently not available.
- However, a security review by a reputable researcher will be published as soon as the apps are deemed mature enough.
- Once Obsidian has established a certain market position, the source code will be published under the GPL, together with the full decentralisation of the Obsidian project.
