HFCP Hyperledger Fabric Certified Practitioner

In Hyperledger Fabric, the enterprise blockchain is a permissioned network where nodes are distributed among the member organizations that participate in the blockchain network. This is in contrast to a public blockchain where anyone can participate anonymously. In a permissioned blockchain like Hyperledger Fabric, the participants are known entities within a business network, such as enterprises or organizations, that have specific permissions and roles within the network. This setup enhances security and trust as each participant is vetted and authorized to take part in the network operations. The architecture of Hyperledger Fabric is designed to support such a governance model, where multiple organizations can interact in a secure and regulated environment, maintaining their own ledgers but sharing data that require consensus across known entities.
