Hyperledger Sawtooth https://sawtooth.hyperledger.org/

In the last quarter work was done to simplify some aspects of Sawtooth Sabre in preparation for it being moved to Transact. SQLite, PostgreSQL and LMDB support for ReceiptStore in sawtooth-lib has been stabilized. The design can be found here .

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:

  • Stabilized SQLite and PostgresSQL support for the ReceiptStore in sawtooth-lib
  • Removed smart permission and Pike from Sabre. Pike has been moved to Grid and had a major update, and Smart Permissions are currently not used anywhere but did rely heavily on Pike.
  • Community bug fixes

Current Plans

The following work is currently in progress:

  • Move portions of Sawtooth Sabre to Hyperledger Transact
  • Migrate to Github Issues, away from JIRA.
  • Rewriting the Sawtooth CLI in Rust
  • Refreshing the Sawtooth website and documentation

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.

Do we have a data matrix about how many enterprise customers using Sawtooth? We have data & stories about Hyperledger fabric , Indy, Aries but Hyperledger Sawtooth DLT we don't have such data. I have faced such questions from the community about Sawtooth as project in production deployment.

I don't know whether this is right place to ask this question.

Probably a question to the Hyperledger staff? What is the source for data and stories about other projects?

On top of my mind, I know personally following projects are using Hyperledger Sawtooth - Indian CBSE 10th and 12th results are captured on it, BondEvalue, Panini's NFT, Tel Aviv Stock Exchange etc.

As I mentioned on the TSC call, there are examples in the community about people sharing what they've built with Sawtooth.  Here is the recording of a presentation about an NFT marketplace built with Sawtooth that was shared at the Media and Entertainment SIG.  I think there's a question here of how to better surface things that are happening across the community so people can find out about this if they aren't actively involved in a specific group.
