permissionless blockchain, virtually anyone can participate, and every participant is anonymous. In such a context, there can be no trust other than that the state of the blockchain, prior to a certain depth, is (BFT) consensus protocols that do not require costly mining. Additionally, in such a permissioned context, the risk of a participant intentionally introducing malicious code through a smart contract is diminished or what Fabric calls “chaincode”, functions as a trusted distributed application that gains its security/trust from the blockchain and the underlying consensus among the peers. It is the business logic

an implementation of distributed ledger technology (DLT) that delivers enterprise-ready network security, scalability, confidentiality and performance, in a modular blockchain architecture. Hyperledger required by competing businesses and regulated industries that exchange assets on a common network. Security & Membership Services - Permissioned membership provides a trusted blockchain network, where participants cipher text.
