Project Health

Health is good. In the last quarter there were 2 releases and the Sawtooth Sabre transaction handler was moved over. This allows for simplification of dependencies for projects using Transact and Sabre.

Releases

Since project creation, the project has had 30 releases. The current release is 0.4.3. The releases are available on crates.io: https://crates.io/crates/transact/versions

Overall Activity in the Past Quarter

Continued incremental improvements to the initial code base. Additional activity shown below. The primary method of discussion has been moved to Discord.

Additional work:

  • Moved Sawtooth Sabre (wasm engine) into Transact. The Sawtooth Sabre transaction processor now pulls in the transaction handler from Transact. (not released)
  • Transact workload improvements
    • Reduced the CPU usage
    • Added remaining duration of the run to the logs
  • Stabilized the "workload-batch-gen" feature in libtransact

Current Plans

Next steps include:

  • Add state caching to improve read performance with large state values
  • Re-evaluate threading model for batch scheduling and execution
  • Setup a documentation site to help explain/advocate the project

Future:

  • Add a next-generation smart contract API / simplified smart contracts (cross-project with Sawtooth, in progress)
  • Further develop the Transact SDK for JavaScript
