Overall Activity in the Past Quarter

Artifact related traits Artifact, ArtifactStore, ArtifactCreator, ArtifactCreatorFactory were added to sawtooth-lib along with the initial traits and structs for a new publisher design.

Sabre performance was improved by implementing state caching in Transact for large pieces of state, such as smart contracts.

Sawtooth Seth has been archived. 

The community continues to discuss Sawtooth-related issues on Discord. The monthly live working sessions continue and now primarily focus on design documents for Sawtooth 2-related work.

Current Plans

The following work is currently in progress:

• Add support to Go SDK for writing consensus engines
• Add Go devmove consensus example
• Merge transaction execution components from Transact into the Sawtooth library
• Merge some Sabre smart contract engine into Sawtooth library
• Create a new consensus library that will be used by the Sawtooth validator
• Sawtooth 2 component designs
• Rewriting the Sawtooth CLI in Rust (paused)

The following work is currently planned:

• Initialize a Sawtooth service for Splinter

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