Consensus is not only reached on the ledger/block level like Ethereum, but differentiates itself on the entire transaction, starting from a client proposing a transaction and endorsement by the network to ordering, validating, and committing the data to the ledger. As I explained previously, in Hyperledger Fabric's mode of participation, there are various types of nodes with each playing different roles and performing different tasks in the process of reaching consensus. With Ethereum, the roles and tasks of participating nodes are identical.
The current implementation of Hyperledger Fabric uses a ...
