SG-PBFT: a Secure and Highly Efficient Blockchain PBFT Consensus Algorithm for Internet of Vehicles
The Internet of Vehicles (IoV) is an application of the Internet of things (IoT). It faces two main security problems: (1) the central server of the IoV may not be powerful enough to support the centralized authentication of the rapidly increasing connected vehicles, (2) the IoV itself may not be robust enough to single-node attacks.

Optimistically Batched PBFT Consensus
In the current technological landscape, a topic of significant interest is Distributed Systems, a concept where a system is built up by separate sub-processes which to the user exhibits a unified front. Due to the fragmented nature of distributed systems, the concept of partial failures exists, where one node in the system may act maliciously and cause

An Improved Scheme for PBFT Blockchain Consensus Algorithm Based on Ring Signature [PDF]
The alliance chain is a kind of blockchain that allows authorized nodes to join in the network.However,when the network condition is poor,the nodes will join and exit dynamically.Therefore,on the basis of ring signature theory,ElGamal digital signature ...

Workload-based randomization byzantine fault tolerance consensus protocol
This paper introduces a new Byzantine fault tolerance protocol called workload-based randomization Byzantine fault tolerance protocol (WRBFT). Improvements are made to the Practical Byzantine Fault Tolerance (PBFT), which has an important position in the

Genome-wide identification of the PEBP genes in pears and the putative role of PbFT in flower bud differentiation [PDF]
Although Phosphatidylethanolamine-binding protein (PEBP) genes have been identified in several plants, little is known about PEBP genes in pears. In this study, a total of 24 PEBP genes were identified, in which 10, 5 and 9 were from Pyrus bretschneideri

Data Privacy Security Mechanism of Industrial Internet of Things Based on Block Chain
In order to solve the problem that data of the industrial Internet of Things (IIoT) is easily tampered with and therefore, the authenticity of data may be questioned, a data-privacy security mechanism of the IIoT based on blockchain is proposed.
