Releases

Since project creation, the project has had 20 releases. The current release is 0.3.7. 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 continues to be held in RocketChat.

  • Experimental support of SQLite and Postgres merkle-radix tree has been added. Along with state pruning.
  • An example application that uses the command family workload to submit transactions directly to sabre was added.
  • Improved workload command rate submission to be more accurate.
  • Modified workload to handle a TooManyRequests response and slow the submission rate until able to submit transactions again.
  • Added `command` as a workload type to the transact workload subcommand.

Current Plans

Next steps include:

  • Move Sawtooth Sabre (wasm engine) into Transact
  • Complete and stabilize SQL database support
  • Reorganization of the project's crate structure
  • 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
