  • SRE team is shaping RPC-as-a-Service prototype, redis is setup, authorization server is prototyped;
  • SRE team also spent lots of time investigating betanet incidents caused by sharding rollout;
  • Core team also added extra tests for sharding upgrade, and synced with Aurora and Indexer to make sure they are not affected;
  • Core team merged parallelization of block catchup and state split;
  • Node Experience made progress on fuzzing runtime, including fuzzing contract deployment;
  • Node Experience added code for better handing missing chunks and faster history replay. Node Experience also added monitoring for NayDuck.

Challenges and Blockers

  • Contract Runtime is blocked on rolling out the new gas counter because it leaks into the protocol spec. However, they found a better approach that does not leak;
  • We are still blocked on publishing nearcore crates;
