-## Roadmap
-
-**1. Block Subscription - Mid September**
-   - Libp2p discovery and block retrieval
-   - SSZ + snappy
-   - `on_block` callback: Save the latest block in fork-choice store, conduct basic checks. GetHead returns the last obtained block.
-   - Beacon API: Return block root (`GET /beacon/states/{state_id}/root`)
-
-**2. Checkpoint Sync - October**
-   - Libp2p primitives for sync
-   - Support checkpoint Sync from a known provider
-   - Sync from the latest finalized block
-   - BeaconAPI: Return headers for head block
-   - EngineAPI: Validate incoming blocks
-
-**3. Attestations - Mid October**
-   - Libp2p attestation retrieval
-   - Basic beacon state representation
-   - Store attestations (last message sent by each validator)
-   - `on_attestation` callback for attestations sent via Gossip
-   - Process attestations from blocks
-   - Beacon API: Return head block root (`GET /beacon/states/head/root`)
-
-**4. Deposits - November**
-   - BLS signature checks
-   - Update consensus state view of deposit contract (`process_eth1_data`)
-   - Process deposit operation to update validator list (`process_deposit`)
-   - Verify block signatures (`verify_block_signature`)
-
-**5. Slots and Fork-choice - Mid November**
-   - `on_tick`/`process_slot` in state transition; a GenServer that calls this periodically
-   - `on_block`: Add slot-related checks and epoch calculations (excluding finalization)
-   - Get-head uses the messages
-   - Block header validation
-   - EngineAPI: Process execution payload
-   - BeaconAPI: Ensure getting head values point to the heaviest
-
-**6. Finality and Slashing - Mid November**
-   - Epoch processing
-   - `on_block`: Prune fork-choice store; reject blocks before finalization
-   - Add RANDAO mix to the beacon state
-   - BeaconAPI: Retrieve finality checkpoints, randao mixes
-   - Process attester slashings and proposer slashings
-   - EngineAPI: fork-choice updates
-
-**7. Rewards, Shuffling - December**
-   - Process rewards `on_epoch` for a checkpoint
-   - Handle Deposits and Withdrawals
-   - Implement RANDAO
-   - Calculate committee for a given state
-   - Conduct shuffling
-   - Integrate with Grafana
-   - BeaconAPI: Retrieve randao mix for a given block 
-
-**8. Validator Features - Mid December/January 2024**
-   - Create attestations
-   - Monitor for slashings
-   - Create slashing proofs
-   - BeaconAPI: Post blocks, slashings, voluntary exits, and withdrawals
