#52 call - https://github.com/ethereum/eth2.0-pm/issues/191
Nimbus
Networking:
- Improve tracking of resources: streams, channels
- Gossipsub audit fixes (done late because 1.1 was not tested enough during its allocated phase)
Core:
- Toledo
- Documentation
- Infura HTTPS support (instead of just websocket)
- Faster ETH1 chain sync/monitoring
- Pre-release 0.6 “Hope” 2 days ago https://github.com/status-im/nimbus-eth2/releases/tag/v0.6.0 with prebuilt Linux binaries and a new release planned today.
- Gradually moving users away from makefiles and will provide precompiled executables
for all major platforms (Windows, Linux, Mac and also ARM builds).
Release management:
- Preparing for mainnet
- Creating sanity checklists
- Creating mailing list
- Monitoring
- Support/coverage plan
- Lessons learned in directory renames (consistency) and permission changes (security)
that were holding databases or were used in systems scripts
- Used to have a way to create deposits and validator keys from Nimbus
To avoid confusion and fight scam attempts, this is now undocumented and developers-only. This way, user message can be “there is only one blessed way to deposit”.
The Nimbus book will redirect to the official launchpad

Testing and release updates
BeaconFuzz:
found 2 consensus vuln on Prysm
- off by one in attestation processing
- wrong epoch when validating proposer slashings
Teku
- spec divergence on slashing similar to Prysm
Working with EF new team member for larger scale fuzzing
Custom fuzzing engine
for now mutation based buzzer is working
Blog post coming soon
Justin:
2 more people joining EF, still looking for security people at the EF
More RFP on testing coming up (networking, chaos testing, …)
——
Testnets: Toledo
including epoch with 100% attestations and participation
New testnet: Pyrmont
Need feedback from client if they can confirm Tuesday.
All OK for clients but couple days might be better.
==> Wednesday
-> mention on discord to not create too much validators.
Sunsetting Medalla, no one against
Vitalik: What testnet should we point people to?
-> Pyrmont. Will be 100k validators controlled by implementers/EF and then opened to public.
—> Have a way to update all users if something happens 1 hour before genesis

Chat
From lightclient to Everyone: (3:48 PM)
re phase 2: is there an appetite to make a backwards incompatible change to the VM (to wasm or something else) in the next 3-5 years?
From Alex Stokes to Everyone: (3:50 PM)
one option on that front: deploy the new vm in a rollup and consider enshrining it as it demonstrates suitability
