RoboSats v0.8.8-alpha: Garage Key, encrypted Nostr chat, and security fixes

RoboSats has released v0.8.8-alpha, an update packed with features aimed at enhancing the privacy, security, and user experience of its non-KYC Bitcoin Lightning exchange. A standout new feature is "Garage Key," which provides users with persistent session IDs without requiring the storage of personal data in browser history or cookies. This innovation significantly boosts user privacy by making sessions less trackable while maintaining convenience for returning traders. Furthermore, the update integrates encrypted chat functionality powered by Nostr, a decentralized social protocol. This allows users to communicate securely and privately during peer-to-peer trade negotiations directly within the RoboSats platform, reducing reliance on third-party messaging services and fortifying user anonymity. The release also includes critical security fixes, addressing various vulnerabilities to strengthen the platform's overall resilience and protect user funds and data. These developments collectively underscore RoboSats' commitment to providing a robust, private, and censorship-resistant marketplace for Bitcoin exchange on the Lightning Network, aligning with core Bitcoin principles of financial sovereignty and personal privacy.
