https://github.com/ethereum/eth2.0-pm/issues/64

----------------------------------

Nimbus team

Core:
- Most of 0.8.1 implemented except SSZ
- On the verge of important changes:
  - SSZ
  - unit testing coverage of most state transition functions
- Issues with justification and finalization
- Genesis bootstrap by Web3
- Libp2p testnet running for 2 weeks
- Updated build so that the go-lip2pd is automatically downloaded

Support:
- Focus on metrics
- Async:
  - fix locking
  - Implementation of sync channels

Eth1:
- Promising speed, 400k/blocks per hour until block 1.3 M
- We hired Andri Lim for Eth1, he has been a very long-time bounty contributor
