Fabric, being a permissioned platform, enables confidentiality through its channel architecture and private data feature. In channels, participants on a Fabric network establish a sub-network where every member smart contract (chaincode) and data transacted, preserving the privacy and confidentiality of both. Private data allows collections between members on a channel, allowing much of the same protection as channels approved the upgrade. Simpler endorsement policy and private data collection updates Fabric lifecycle allows you to change an endorsement policy or private data collection configuration without having to repackage
