What consensus algorithm does Hyperledger Fabric use?
Hyperledger Fabric utilizes a modular architecture that allows for different consensus algorithms to be plugged in. The consensus mechanisms used by Hyperledger Fabric include Solo, Kafka, and Raft, each suitable for different use cases and environments. Solo is mainly for development and testing, Kafka for high-throughput production environments, and Raft for production environments requiring high availability and fault tolerance.


When was the proof of stake consensus algorithm introduced?
The proof of stake consensus algorithm was introduced as a category of consensus algorithms for public blockchains, depending on a validator's economic stake in the network. It was proposed as an alternative to proof of work, aiming to address issues such as energy efficiency and centralization risk.
