Hyperledger Sawtooth

Project Health

The primary focus of the last quarter was on adjusting the relationship between Sawtooth and Transact to move more functionality from Sabre and Workload capabilities into Transact.

Due to end-of-year holidays, fewer contributor meetings were held this quarter, but the meetings which were held had active discussion on Sawtooth's relationship to other projects and progress on Sawtooth's documentation effort.

Questions/Issues for the TSC

No new issues.


  • Sawtooth Library v0.6.4 -  10/25/2020
  • Sawtooth Library v0.6.5 -  11/12/2020
  • Sawtooth Sabre v0.6.1 - 11/12/2020

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.

The Sabre Transaction family version has been updated to "1" and is now backwards compatible with older versions, allowing it to accept transactions from versions 0.5 and 0.6.

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

The following work is currently planned:

  • Rename 'master' branches to 'main', as suggested by HL.
  • Migrate to Github Issues, away from JIRA.
  • Create a new consensus library that will be used by the Sawtooth validator
  • Initialize a Sawtooth service for Splinter

Plans will continue to be developed as part of the working sessions.
