Identity keys are now detached from users, ensuring that order identity keys are encrypted. This means that even in the event of a database leak, there is no direct correlation between users and their orders. By implementing this separation, we enhance user privacy and security, making it significantly more challenging for unauthorized parties to link sensitive information back to individual users. This approach not only protects user identities but also fosters trust in the platform, as users can engage with confidence knowing their data is safeguarded.

Mostro has implemented a new end-to-end encrypted chat for its Bitcoin P2P exchanges, designed to resolve disputes without compromising user privacy. Using advanced cryptography (DHEC), each transaction generates a unique *shared master key* known only to the buyer and seller. In case of a dispute, either party can voluntarily hand over this key to a mediator, allowing them to decrypt and review only that specific conversation, which is unalterable and cannot be deleted by scammers. This innovative feature ensures the availability of verifiable evidence for fair resolution, avoiding the need for centralized message storage and protecting the overall privacy of communications on Mostro.

Keys management on Mostro is based on a security system as simple as exchanging wrapped gifts and changing safe combinations: each message between the user and the platform uses ephemeral keys that function as *disposable locks* while each buy or sell order is linked to a different key derived from a unique seed, ensuring that the information and transactions are always protected.

Over the past year, Mostro has made significant strides in key management (rotating keys for each trade and improving privacy), standardizing orders on Nostr through the new NIP-69, and consolidating its ecosystem thanks to participation in the b4os residency, the creation of the Mostro Foundation, and the development of libraries (mostro-tools) and new clients (a mobile app and the Mostrui terminal interface). All of this aims to provide a privacy-focused, user-friendly peer-to-peer exchange platform, supported by HRF, Opensats, and other contributors.
