The Block is available as a native app on all major desktop platforms: Windows, Mac, and Linux. The app includes support for themes and even comes with two themes built in. Users can bookmark searches, sellers, and items, for later use. Privacy level settings let users chose the arrangement that works best for them; for instance, users can chose between using their own copy of the Ethereum blockchain, or a remote copy maintained by the BitBoost developers. Users can be known to other users by their Ethereum address, or they may choose an alias.
