• Commands
• Testing a contract
• Creating Naïve impementation for a trustless service like Corda contract

Implementing contracts and flows

• Constraints (transaction level, value level)
• Typical contract patterns
• Transactions, the TransactionBuilder
• Deployment, implementation
• Introduction to Flow programming
• Further development and extension of the previous implementation with naïve Flow.

Advanced Corda programming
