For @bluesky + @at_protocol devs, this means you can add secure, encrypted group messaging to your apps today.
How it works:
• Your XMTP Inbox signs approval of your DID
• Your DID's data repository stores the Inbox ID + signature

Quantum computing isn’t just sci-fi; it will break the cryptography we rely on for messaging.
While applications like Signal can protect at the application level, there has been no quantum-level secure open messaging protocol for developers.
XMTP is this solution for the world.

To build a new communication network that requires global trust, you have to open source everything. True security comes from transparency.
This is why XMTP's node software is open source—anyone can inspect, & verify every line of code. No more blind trust in a black box.

XMTP is more than a protocol, it's a network of apps & identities.
Meaning, the 2.2M identities on XMTP-- across @base, @ensdomains, @LC, @unstoppableweb & FIDs-- can use any app, such as @CoinbaseWallet, @family, or @converseapp_ (+ 60 other apps)
This is true ownership.
