- Introduced the Blossom package, implementing essential features for handling blob storage, including upload, retrieval, and deletion of blobs. - Added authorization mechanisms for secure access to blob operations, validating authorization events based on Nostr standards. - Implemented various HTTP handlers for managing blob interactions, including GET, HEAD, PUT, and DELETE requests. - Developed utility functions for SHA256 hash calculations, MIME type detection, and range request handling. - Established a storage layer using Badger database for efficient blob data management and metadata storage. - Included placeholder implementations for media optimization and payment handling, setting the groundwork for future enhancements. - Documented the new functionalities and usage patterns in the codebase for better maintainability and understanding.
