On the Practicality of Practical Byzantine Fault Tolerance [PDF]

open access: yes, 2012
Byzantine Fault Tolerant (BFT) systems are considered by the systems research community to be state of the art with regards to providing reliability in distributed systems. BFT systems provide safety and liveness guarantees with reasonable assumptions, amongst a set of nodes where at most f nodes display arbitrarily incorrect behaviors, known as ...

An improved PBFT consensus algorithm based on grouping and credit grading

open access: yesScientific Reports, 2023
To improve the blockchain consensus algorithm practical Byzantine fault tolerance (PBFT) with random master node selection, which has high communication overhead and a small supported network size, this paper proposes a Byzantine fault tolerant consensus

Improved Fault-Tolerant Consensus Based on the PBFT Algorithm

open access: yesIEEE Access, 2022
Nowadays Practical Byzantine Fault Tolerance (PBFT) algorithm has become the most extensive consensus algorithm in the alliance chain. However, the PBFT algorithm is usually only applicable to small networks due to high communication complexity and poor ...

Efficient Quantum-secure Byzantine Fault Tolerance Consensus Mechanism Based on HotStuff [PDF]

open access: yesJisuanji kexue
The public-key digital signature used by Byzantine fault tolerance consensus mechanism in the classic blockchain exposes vulnerability to quantum computers that have the exponential acceleration of computing power,and therefore have security risks.To ...

Entangled state testing in the quantum Byzantine agreement

open access: yes网络与信息安全学报, 2016
In distributed computing,Byzantine agreement is a practical method to solve its fault-tolerance problem.There is a variation of the Byzantine agreement which is called detectable Byzantine agreement.This kind of protocol is unsolvable by classical means ...

High throughput Byzantine fault tolerance [PDF]

open access: yesInternational Conference on Dependable Systems and Networks, 2004, 2004
This paper argues for a simple change to Byzantine fault tolerant (BFT) state machine replication libraries. Traditional BFT state machine replication techniques provide high availability and security but fail to provide high throughput. This limitation stems from the fundamental assumption of generalized state machine replication techniques that all ...
