## TF Validator Cluster

In version 4.0 we will have minimum 9, maximum 30 Protectors (commercial partners from different continents) who run a TF Validator Cluster.

Each TF Validator Cluster has following functions

- consensus chains e.g. the TFChain for 3.x Grid, TF Validators for 4.x grid
- TF explorers (interfaces to allow us to digest and find the relevant information easier from the TFGrid)
- TF Hub's (conversion service from docker to deduped filesystems as used for our compute workloads).
- a node for the Bridging functionality (INCA support on multiple chains)
- CI/CD Service for TFGrid code (Continuous Integration, Continuous Development)
- All necessary webservices (websites, manuals, UI)
- TF Marketplace & Components as relevant for the TF Liquidity Pool.
