Inspired by BitTorrent Sync, VoidData is three things:
First of all, it is a simple database using a key-store model. No SQL processing is possible in an attempt to reduce bloat. Secondly, it has a GUI for management of said data. Primarily for debugging purposes, it also acts as a scratchpad for the data you can access. Thirdly (and most prominently), VoidData enables cloud data storage via peer-to-peer transfer of data.
The last part is what makes VoidData really unique. The principle is to allow you to store instances of data with other VoidData users in exchange for storing some of their data. This can be done securely (storage-only), cooperatively (multi-user) or trusted (ring-of-trust secure storage).
VoidData intends to support peer cloud storage first, followed by the GUI and finally advanced encryptionfor security. In short, don't store secure information publicly until release!
