Sawtooth Sabre v0.7.2 - 06/24/2021

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.
