# ThreeFold grid inspired by nature

![](img/nature_twin_.jpg)

- Just like we have trillions of cells in our body, so can billions of twins live next to each other
- Each twin has memory, knows how to communicate, has knowledge, history, ...
- Twins like cells cannot live without a body = TFGrid.

## This approach scales for ever

![](img/unlimited_3nodes.png)

- There can be unlimited amounts of TFNodes as well as Executors (Digital Twins and Web4)
- There are no bottlenecks nor centralization points
- Our peer2peer network technology takes care of routing and security issues between the Twins and the TFNodes. The shortest paths is always looked for.


## ThreeFold is compatible with the current IT world.

While we push for a new possible, in the meantime our TFGrid infrastructure is compatible with the existing IT and internet ecosystem.

- any workload which can run inside linux can run on top of our TFGrid
- any web developer can create apps (experiences) on top of the Digital Twin
- just like kwatth is used as a measurement of capacity for solar panels we have [CU](tfgrid:cloudunits), [SU](tfgrid:cloudunits) and [NU](tfgrid:cloudunits), which are called cloudunits.
- TFT is required to buy CU,SU,NU
