Summary

We've reached the end of our journey on smart contract development in Hyperledger Fabric. Let's spend a few moments recapping the key steps:

• We started by examining the central concept of a multi-party transaction, which represents the mutual agreement by a set of organizations in a network consortium to a change to a set of business objects.
• We moved on to see how transactions involving these business objects were stored in a distributed ledger replicated across all network organizations, and how it held both the transaction history of these objects and their current value.
• We discussed how smart contracts operate within a consensus framework, and the operations that need to happen for a smart contract to generate a multi-party transaction that is stored in the ledger.
• We examined the important interplay between a smart contract and the ledger's current value in generating a transaction response expressed as before- and after-images...
