Consensus algorithm

With respect to participating in consensus, the two platforms under discussion are at opposite ends of the spectrum. Ethereum is a public and permissionless blockchain, whereas Hyperledger Fabric is a private and permissioned blockchain. This means that the consensus algorithm used for these platforms differs in complexity (namely, cryptographic difficulty) and execution. Because trustless operations can be performed on the Ethereum network, it requires certain PoW (for example, cryptographic hashing) by miners to keep the data in the ledger consistent. In contrast, Hyperledger Fabric's interpretation of consensus is more refined due to its operating in permissioned mode, which provides more fine-grained access control ...
