Overall Activity in the Past Quarter
The community continues to discuss Sawtooth-related issues on Rocketchat. Live working sessions have also been used on a monthly basis to discuss the future of Sawtooth, with participation from the community.
Sawtooth Updates:
- A memory leak was discovered in Sawtooth Sabre caused by the version of wasmi pulled in. The leak was improved by updating wasmi from 0.4 to 0.9. This update also provided a small performance increase.
Current Plans
The following work is currently in progress:
- Rewriting the Sawtooth CLI in Rust
- Refreshing the Sawtooth website and documentation
- Move portions of Sawtooth Sabre to Hyperledger Transact
- Migrate to Github Issues, away from JIRA.
- Add a receipt store trait that will be implemented with LMDB, SQLite and PostgreSQL backends.
The following work is currently planned:
- Create a new consensus library that will be used by the Sawtooth validator
- Initialize a Sawtooth service for Splinter
- Improve Sabre performance
Plans will continue to be developed as part of the working sessions.
