 ## Roadmap
 
-0. Initial project setup and integration with [lean-quickstart](https://github.com/blockblaz/lean-quickstart)
-1. Load network configuration and genesis block
-2. Connect to P2P layer and listen for new blocks
-3. Compute next chain state from received blocks
-4. Receive attestations from peers and apply fork-choice rule
-5. Produce and broadcast attestations for the head of the chain
-6. Build new blocks and broadcast them to peers
+The initial project setup and integration with [lean-quickstart](https://github.com/blockblaz/lean-quickstart) are complete.
+
+### Listen for new blocks
+
+This milestone focuses on connecting to other clients and listening for new blocks through gossipsub.
+
+- Connect to other peers via libp2p ✅
+- Respond to STATUS messages from other peers 🏗️
+- Listen for new blocks in gossipsub
+
+### Compute current chain state
+
+This milestone focuses on computing the chain state from the gossiped by peers received.
+
+- Generate initial state from genesis configuration
+- Implement state transition function
+- Transition state on each new block
+
+### Apply fork-choice rule
+
+This milestone focuses on choosing the head of the chain based on gossiped attestations.
+
+- Listen for attestations in gossipsub
+- Implement fork-choice rule
+- Apply fork-choice rule based on received attestations
+
+### Produce blocks and attestations
+
+This milestone focuses on performing the duties of a validator.
+
+- Produce and broadcast attestations on each slot
+- Compute current proposer for each slot
+- Build and broadcast new blocks when proposing
