Youngjong Kim, Jinho Park
2020 Human-Centric Computing and Information Sciences  
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 [18] , which is  ...

Analysis and Design of Open Decentralized Serverless Computing Platforms

Sara Ghaemi
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.  ...
