Bull Bitcoin has introduced Recoverbull, an open-source protocol aimed at enhancing the security of hot wallet backups. This innovative system allows users to store encrypted backup files on cloud services such as iCloud or Google Drive, while keeping decryption keys on an anonymous key server. The protocol is designed to be user-friendly, enabling non-technical users to create backups in just two minutes using a simple password. Recoverbull employs a 2/2 isolated storage system and limits key recovery attempts to thwart brute-force attacks, ensuring robust security. By maintaining anonymity and preventing key exposure to service providers, Recoverbull offers a secure and efficient solution for managing hot wallet backups.
