Hellerstein, Heidi Howard, and Ion Stoica. 2024. Read-Write Quorum Systems Made Practical. WebA quorum system is a collection of sets (quorums) every two of which intersect. Quorum systems have been used for many applications in the area of distributed systems, including mutual exclusion, data replication, and dissemination of information. Given a strategy to pick quorums, the load LS is the minimal access probability of the busiest element, minimizing …

WebRaft is a consensus algorithm designed as an alternative to the Paxos family of algorithms. It was meant to be more understandable than Paxos by means of separation of logic, but it is also formally proven safe and offers some additional features. Raft offers a generic way to distribute a state machine across a cluster of computing systems, ensuring that each … Web2012 ACM Subject Classification Theory of computation æ Distributed computing models Keywords and phrases Blockchain, Stellar, Byzantine quorum systems 1 Introduction Blockchains are distributed databases that maintain an append-only ledger over a set of potentially Byzantine nodes. The nodes use a Byzantine fault-tolerant (BFT) consensus
