This paper proposes a Hybrid decentralized Practical byzantine fault tolerance Blockchain Framework with two-step verification for OpenStack message queue service. ... Additionally, a reduction in the security vulnerability in the OpenStack message queue information with saving the message queue information into each node by blockchain-based decentralized data duplication ... HdPBF for OpenStack message queue PBFT Blockchain Framework The Blockchain Framework in this paper divided version 0.6 of the Hyperledger Fabric based on PBFT and upgraded the RocksDB  , which is ...doi:10.1186/s13673-020-00238-6 fatcat:hgqxwadykndgbjhhh3ruifygjq
We propose a blockchain interoperability solution for permissioned blockchains based on the publish/subscribe architecture. ... Finally, we present a list of possible directions for future research. Our survey identifies the lack of a detailed performance evaluation for DAG-based distributed ledgers presented so far. ... For example, Tendermint combines PoS and PBFT; EOS takes a hybrid design combining PBFT and DPoS. Both target on improved performance and enhanced security. ...doi:10.7939/r3-28re-v088 fatcat:b5545e3or5f4bneuo5inbhdr6e
The component is typically triggered by the occurrence of some event (possibly a message on a message queue) and may trigger some other event to have its output data consumed. ... the OpenStack Controller. ...doi:10.5281/zenodo.5561042 fatcat:o5ecnvwvifhmveigarvfgih3l4
SUPERCLOUD state-machine replication will use Hyperledger fabric open-source blockchain as its envelope, which is first discussed in Chapter 2. ... This deliverable introduces the processing functions for data management in the SUPERCLOUD. ... for the blockchain. ...doi:10.5281/zenodo.263831 fatcat:ksk4ze2tuncfbexjzsorjnoabe
We conduct an analysis and discuss how the new system breaks out the Blockchain Trilemma, which claims that it is almost impossible for a ii ... In this thesis, we first conduct a comprehensive literature review on both distributed ledger technology applications in IoT and the performance evaluation of such decentralized systems. ... In particular, I would like to thank my dear wife for her encouragement and support for my research. ...doi:10.7939/r3-21yj-3545 fatcat:ntnuqb2morgphj225jbusmflj4
