Key Components - Hyperledger Fabric Internals Documentatio

Note: when we use the term upgrade in Hyperledger Fabric, we're referring to changing the version of a component (for example, going from one version of a binary to the next version). The term update, on the other hand, refers not to versions but to configuration changes, such as updating a channel configuration or a deployment script. As there is no data migration, technically speaking, in Fabric, we will not use the term migration or migrate here Hyperledger Fabric Components Like all blockchain-based technologies or platforms, Hyperledger Fabric is built upon a few central components: a distributed ledger for all data recorded about the transactions multiple peers (or nodes What is Hyperledger Fabric?
