+# TFGrid release 3.0
+
+TFGrid 3.0 will be released gradually during Q3/Q4 2021. 
+
+## What's new ?
+
+TFGrid 3.0 is a full redesign of the ThreeFold Grid architecture. The main purpose of this redesign is to decentralize all the components that the Grid is built with. 
+
+### TFChain 3.0
+
+A decentralised chain holding all information on entities that make up the ThreeFold Grid. It runs on Parity Substrate blockchain infrastructure. 
+
+Features :
+- Your identity and proofs/reputation on our blockchain
+- All info about TFGrid (nodes, farmers, …)
+- A Graphql interface to be able to query the blockchain
+- Support of side chains (unlimited scalability, allow others to run their own blockchain)
+- TFT exists now also on TFChain (allows us to work around Stellar scalability issues)
+- Bridge between TFT on Stellar and TFT on TFChain (one way to start)
+- Blockchain based provisioning process
+- TFChain API (javascript, golang, vlang)
+- Support for 'Infrastructure as Code' : IAC frameworks 
+   - Terraform
+   - Kubernetes, Helm, Kubernetes
+   - Ansible (planned for Q4 2021)
+- Use RMB = peer2peer secure Reliable Message Bus to communicate with Zero-OS
+
+### Proof of Utilization
+
+- Resource utilisation is captured and calculated on hourly basis
+- Resource utilisation stored in TFChain
+- An automated discount system has been put in place, rewarding users who pre-purchased their cloud needs. Price discounts are applied, in line with amount of TFT you have in your account and the period you are holding these TFT.
+E.g. if you have 12 months worth of TFT in your account in relation to the last hour used capacity you get 40% discount, 36 months results in 60% discount. 
+
+### New Explorer UI
+- An updated User Interface of the TF Grid Explorer, nicer and easier to use
+- It uses the Graphql layer of TFChain
