Consensus protocols are the basis for the state machine replication approach to distributed computing, as suggested by Leslie Lamport [2] and surveyed by Fred Schneider. [3] State machine replication is a technique for converting an algorithm into a fault-tolerant, distributed implementation.
It is a distributed algorithm that coordinates all the processes that participate in a distributed atomic transaction on whether to commit or abort (roll back) the transaction. This protocol (a specialised type of consensus protocol) achieves its goal even in many cases of temporary system failure (involving either process, network node ...
The problem of voting for a single value by a group of independent entities is called Consensus. By extension, a series of values may be chosen by a series of consensus instances. This problem becomes difficult when the participants or their communication medium may experience failures.
The Paxos consensus algorithm by Leslie Lamport, and variants of it such as Raft, are used pervasively in widely deployed distributed and cloud computing systems. These algorithms are typically synchronous, dependent on an elected leader to make progress, and tolerate only crashes and not Byzantine failures.
These algorithms typically do not work well for larger read sets, as they do not easily reach a global optimum in the assembly, and do not perform well on read sets that contain repeat regions. [1] Early de novo sequence assemblers, such as SEQAID [ 2 ] (1984) and CAP [ 3 ] (1992), used greedy algorithms, such as overlap-layout-consensus (OLC ...
Raft 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. [1]
WASHINGTON (Reuters) -The United States issued fresh sanctions on Wednesday on several Russia-based entities over their involvement in the Nord Stream 2 gas pipeline, the State Department said ...
Originally developed in 2019 by Microsoft [2] under the name Coco and later rebranded to Confidential Consortium Framework (CCF), it is an open-source framework for developing of a new category of performant applications that focuses on the optimization of secure multi-party computation and data availability.
