Hey friends if you are trusting your privacy to telegram you are sadly uninformed. Telegram has been compromised by governments and is not a safe store of information or files anymore. Also Obsidian requires no identifying information including your phone number. Also remember that Obsidian is a platform and this is just it's first application.

Very well said and concise description of the project. There are a lot of finer details which I think are worth noting such as the fact that the level of encryption that The Obsidian Platform is utilizing is second to none. 

The Obsidian Messenger (OSM) is the first App built on the chain although the messages don't actually travel on it as You mentioned in the above explanation (they are P2P off chain). The messenger platform offers end-to-end-message encryption with perfect forward secrecy (PFS)
relying on Elliptic Curve Diffe-Hellmann (ECDH). Obsidian IDs are identifers related to Curve25519
signing keys, offering 128 bits of security. The messenger platform requires no user identifers, such as
an e-mail address; Obsidian IDs are unrelated to authenticated user identities.

Maybe your wondering what the heck im talking about ? lol. heres a more simple explanation:
Diffie-Hellman is a way of generating a shared secret(key) between two people in such a way that the secret(key) can't be seen by observing the communication. That's an important distinction: You're not sharing information during the key exchange, you're creating a secret(key) together.

This is particularly useful because you can use this technique to create an encryption key with someone, and then start encrypting your traffic with that key. And even if the traffic is recorded and later analyzed, there's absolutely no way to figure out what the key was, even though the exchanges that created it may have been visible. This is where perfect forward secrecy comes from. Nobody analyzing the traffic at a later date can break in because the key was never saved, never transmitted, and never made visible anywhere.

This project is such a drak horse and has huge potential that will only start to be realized on the 24th of Dec so I encourage eveyone who sees this to take a few mins of your time to check it out. You will not regret it.
