BlackHole

About

BlackHole is a high-performance, decentralized file transfer service that leverages blockchain technology for enhanced security and privacy. Originating from the United States, it operates on a freemium and open-source model, offering a comprehensive product portfolio including unlimited storage, secure file sharing with password-on-link options, file compression, data streaming, and a Windows Explorer Extension. It is available across Mac, Windows, and Online platforms, positioning itself in the File Sharing and Security & Privacy sectors. While praised for its clean user interface, security, and privacy features, user feedback also highlights challenges such as slow upload speeds, a potentially messy account creation process, and difficulties in syncing multiple devices. The project maintains an active presence on GitHub (github.com/blackholeorganization) and Twitter (twitter.com/alternativeto).
