Nimbus
Audit:

- Trail of Bits
- NCC
3 phases, 2 weeks audit, 2 or 3 weeks fixes.
- Networking
- Beacon Core
- Validator Core
=> Fresh take on audits, similar to Eth2, have multiple auditors in collaboration
=> Fixing issues as they are raised
Beacon core:
- Reducing memory usage (smarter caching), below Lighthouse
- Sync speed, not satisfactory yet
Networking:
- Attestation not properly propagated (biggest issue on Altona)
- several improvement like better handling stale connections
- Discv5 fixes
Beacon/Validator split:
- Fix finalisation issues
Crypto:
- Key management EIP2333
-> Wallet implies to hold withdrawal keys
-> deposits compatible to the Ethereum Launchpad
- Reviewed BLS backends
- Updated to Milagro to use Miracle/core following license change
- BLST wrapped

Research updates
Joseph: Everybody should put some resources to attacking the attacknets
Leo: Snappy compression ratio and blocks/s speed with snappy

Will run different clients on the same network

More gossipsub changes will be introduced later
Verification, sequence numbers will be standardised (currently some propagated, dropped or randomized depending on the client)
——————
Vitalik: how to kickstart phase 1 implementation?
Danny: currently clients focused on shipping
