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)
