Project Health

Health is good. In the last quarter there was one release. This release includes a number of fixes to the stability of the SQL-backed merkle state implementation, including stable behavior of the merkle tree after state pruning has been applied.  It also includes changes to support using the SQL-backed merkle state in the context of a wider transaction.

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:

• Fix state pruning when using SqlMerkleState
• Allow the use of SqlMerkleState with-in existing transactions
• Stabilize the "state-merkle-sql-in-transaction" feature by removing it
• Make updates necessary for the eventual stabilization of the "playlist-smallbank" feature

Current Plans

The Transact team is investigating merging libtransact into sawtooth-lib in order to simplify the overall dependency tree. sawtooth-lib did not exist when the Transact project was created, but might now be a good fit.

Future:

• Re-evaluate threading model for batch scheduling and execution
• Setup a documentation site to help explain/advocate the project
• Add a next-generation smart contract API / simplified smart contracts (cross-project with Sawtooth, in progress)
• Further develop the Transact SDK for JavaScript
