The Consensus Protocol upgrades a blockchain, which guarantees a sequential, unambiguous transaction ordering. Blocks ensure that the blockchain is integral and uniform across a network of distributed nodes. Different blockchain implementations use different consensus protocols. This paper offers a brief overview of the most important discrepancies between the Hyperledger Fabric and Ethereum distributed ledger technologies (DLT). © 2021 IEEE.eninfo:eu-repo/semantics/closedAccessdistributed ledger technologies (DLT)EthereumHyperledger FabricOrdering Service (OS)Conference Object10.1109/HORA52670.2021.94612942-s2.0-85114448451N/A
