Testing and Release updates
Eth 1.0 release candidate WIP
Zinken
Networking tests defined by YAML
Beacon Fuzz, new blogpost: https://blog.sigmaprime.io/beacon-fuzz-08.html
BLS differential fuzzing:
- 2 critical bugs on BLST, patched (atm targeting the Rust bindings)
Differential buzzer on AWS, 2 small differences between clients
Less and less exploitable bugs between clients
Plan to crate their own custom fuzzer engine.
-> can rotate/swap BeaconState with more granularity
-> Fuzzing speed, can have the BeaconState in memory instead of disk IO
-> Both diff and mutation based fuzzing in the same target
