Brief Summary

• Cost of the callbacks for cross-contract calls is reduced by 99.3% (by 4.7Tgas). This is not enabled on Mainnet yet;
• Rust SDK book is available here https://www.near-sdk.io/ ;
• MetaBUIDL Hackathon deadline extended by 1 week;

Results

• Core implemented state splitting for re-sharding during block catchip and syncing;
• Core drafted a new more efficient state design;
• Node Experience collected wallets with sufficient tokens to run Chunk-Only producers;
• Developer Platform merged “extension system” for the CLI;
• Developer Platform added support of successful/failed callbacks to Rust SDK;
• Developer Platform released runner-js v0.6.0;
• Developer Relations are collecting community feedback on near-runner;

Challenges and Blockers

• Aurora is still blocked on Contract Runtime team improving performance of Wasm execution, see the project board here;
• Improvements to the fees are in general blocked on several weird behaviors that need to be thoroughly investigated: IO costs seem to be inconsistent, potentially because of the underlying Rocksdb; Loading of Wasm module depends on the number of Wasm functions.
