 The TFChain Blockchain will keep a record of all Entities, Twins, Nodes and Farmers in the TF-Grid network. This makes it easy to integrate the Smart Contract on TFChain as well since we can read from that storage in runtime.

-#### Reliable Message Bus
-
-The user sends the contractID and workload through the RMB to the destination Node.
-
-RMB is our Reliable Message Bus, workload definitions don't get registerd on the TFChain but directly send peer2peer, this is more secure and private, the smart contract still controls the overall process.
-
-The Node reads from the [RMB](https://github.com/threefoldtech/rmb) and sees a deploy command, it reads the contractID and workload definition from the payload.
-It decodes the workload and reads the contract from chain using the contract ID, the Node will check if the user that created the contract and the deployment hash on the contract is the same as what the Node receives over RMB. If all things check out, the Node deploys the workload.
-
 #### consumption reports
 
 The Node periodically sends consumption reports back to the chain for each deployed contract. The chain will compute how much is being used and will charte the user in TFT.

 Following benefits
 
 - IT workloads can be deployed 100% deterministic, this means all specific properties of the workloads like necessary files, network bridges, processes, ... are all known at build time, this leads to good security and predictability.
-- Consensus can be required for deploying a workload on the ThreeFold grid.
+- Consensus can be required for deploying a workload.
 - Auditing and full transparancy on what has been deployed by who at what time.
