2020-09-03 Eth2 Call 47.txt

Agenda: https://github.com/ethereum/eth2.0-pm/issues/178

Nimbus:

Audit:
- Highlighted several potential for malicious attestations or blocks
  to exhaust the system memory, so now use bounded buffer and explicit drops
  when late
  
Current focus:
- Log file filling disk -> moving default logging for something suitable to end user
  - also differentiating own attestations/blocks vs the noise of the network
- DB filling disk: working on pruning
- NBC RAM usage: still having a resource leak, likely libp2p or asynchronous timers holding objects forever.

Multinet scripts:
-> small network with 8x64 LH, 8x64 nim, 8x64 pry
