Improved Consensus Protocol for IoT Trust Management Systems
ABSTRACT With the rapid development of the internet of things (IoT), the security collaboration between devices poses higher demands on traditional trust management. Blockchain technology, due to its decentralisation and tamper‐proof characteristics, has become an effective solution for building trustworthy IoT systems.

Experiences with Fault-Injection in a Byzantine Fault-Tolerant Protocol [PDF]
The overall performance improvement in Byzantine fault-tolerant state machine replication algorithms has made them a viable option for critical high-performance systems. However, the construction of the proofs necessary to support these algorithms are complex and often make assumptions that may or may not be true in a particular implementation ...

Byzantine Fault-Tolerance with Commutative Commands [PDF]
State machine replication is a popular approach to increasing the availability of computer services. While it has been largely studied in the presence of crash-stop failures and malicious failures, all existing state machine replication protocols that provide byzantine fault-tolerance implement some variant of atomic broadcast.

Serein: A parallel pipeline‐based DAG schema for consensus in blockchain
As the core technology of blockchain, consensus mechanisms play a crucial role in ensuring the consistency and reliability of blockchain systems. In a decentralized and open system environment like blockchain, traditional consensus algorithms are often ...

Components of the Plonk System. ABSTRACT The promise of blockchain applications is transformative in terms of certificate verification and managing digital identities in the various fields, such as education, healthcare and land records. Nevertheless, current blockchain‐based certificate solutions have serious shortcomings: most are based on simple ...

Non-determinism in Byzantine Fault-Tolerant Replication
Service replication distributes an application over many processes for tolerating faults, attacks, and misbehavior among a subset of the processes. The established state-machine replication paradigm inherently requires the application to be deterministic.

Study of Blockchains’s Consensus Mechanism Based on Credit
Practical Byzantine fault tolerance (PBFT) is one of the most popular consensus protocols of the blockchain. However, in the PBFT, the enthusiasm of reliable nodes cannot be stimulated effectively, and a large amount of communication resources are used ...

Generalized Paxos Made Byzantine (and Less Complex)
One of the most recent members of the Paxos family of protocols is Generalized Paxos. This variant of Paxos has the characteristic that it departs from the original specification of consensus, allowing for a weaker safety condition where different ...

Two-layer grouped Byzantine fault tolerance algorithm for UAV swarm
To reduce the communication complexity and improve the robustness of blockchain network, a two-layer grouped Byzantine fault tolerance algorithm for unmanned ariel vehicle (UAV) swarm was proposed.First, nodes were divided into several groups according ...
