Summary

We conclude our chapter on advanced smart contract and application development topics for Hyperledger Fabric. Let's recap a few of our key learning points:

• We started the chapter by continuing our examination of the fundamental operations an application can perform:
  • Query a ledger
  • Submit a new transaction
  • Listen for ledger notifications
• We then took a deeper dive into advanced topics, including how to customize how the application interacts with the network using strategies and handlers. We saw how they allow applications to incrementally increase their influence over how the SDK interacts with the network without ever worrying about the network details.
• Our extensive tour of private data collections allowed us to design networks that support privacy and verifiability.
• We looked at both state-based and collection-based endorsement and saw how they complement contract-based endorsement.
