Performance Evaluation of Hyperledger Fabric

Blockchain technologies to mitigate COVID-19 challenges: A scoping review

“…For example, Bitcoin was reported to have a 10-minute delay to confirm a transaction and a maximum throughput of 7 transactions per second [46] . Some private blockchains (such as Hyperledger) allow for more customization of different parameters to enhance the blockchain performance in different applications [47] .…”

Transparent Data Dealing: Hyperledger Fabric Based Biomedical Engineering Supply Chain

“…Execute-Order-Validate architecture is a new approach to the transaction that enable HF to operate uniquely from other blockchain platform. Indeed, based on the consensus protocol, transactions are ordered in HF [14]. Then, in the execution phase, each peer executes transactions sequentially in the same order.…”

“…• Solo: It has only one ordering node that makes it a single-point-of-failure. Thus, solo ordering service is not suitable for business [14]. However, it could be employed for non-critical operation such as education or product development.…”

“…• Kafka: Kafka follows the leader and follower approach, where the leader orderer sends the transactions to the follower orderer nodes. The choice of the leader is made dynamically, and as long as the majority of the nodes is up, the system is built to sustain using the Crash Fault Tolerant (CFT) mechanism [14]. The HF also has the option that supports multiple orderers, but the downside is the challenge to deploy [17].…”

“…• Raft: It is a new ordering service of HF and possess similar characteristics to Kafka and also has the same concepts i.e., follow the leader and follower methods. However, Raft is relatively simple to set up [14].…”
