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

Additional work:

  • Added a new, experimental, version of the state traits, which better support different threading models
  • Added state caching to SqlMerkleState in order to improve read performance of large values

Current Plans

Next steps include: 

  • Fix state pruning when using SqlMerkleState
  • Allow the use of SqlMerkleState with-in existing transactions
  • 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
