"Bitcoin (SV) is the most secure hard disk that will ever exist. And BitDB is the memory that lets you make the most out of it."
Introducing BitDB. A Random Access Memory (RAM) for Bitcoin (SV).
BitDB solved the missing link, where developers build their own databases just to build apps. Resulting in a volume of inconsistent databases and incompatible apps. Imagine Facebook doesn't work with Twitter, or Uber doesn't work with Grab and Careem.
BitDB is a Universal Bitcoin (SV) Database that enables developers to focus on building compatible apps. A precursor to the world of MetaNet.
