Concurrent execution of transactions in a peer-to-peer database network

Mehedi Masud, Sultan Aljahdali
2011 International Journal of Intelligent Information and Database Systems  
Transaction execution in a peer-to-peer database network specifies an update made to a peer's instance is applied to the peer's local database and propagated to related peers.  ...  Reference to this paper should be made as follows: Masud, M. and Aljahdali, S. (2011) 'Concurrent execution of transactions in a peer-to-peer database network', Int.  ...  In a peer-to-peer database network, when a user submits a transaction T i to a peer P i , the transaction is executed at P i and appropriate actions are performed in its local database DB i .  ...

A distributed database view of network tracking systems

Jason Yosinski, Randy Paffenroth, Oliver E. Drummond
2008 Signal and Data Processing of Small Targets 2008  
In many decentralized tracking systems, trackers communicate with their peers via a lossy, bandwidth-limited network in which dropped, delayed, and out of order packets are typical.  ...  Using the two-phase commit algorithm, a well known technique for resolving transactions across a lossy network, we describe several ways in which one may build a distributed multiple hypothesis tracking  ...  The two-phase commit protocol allows all peers in a distributed database to agree either to commit or to abort a transaction.  ...

Blockchain for Artificial Intelligence

Avi Garg
2017 International Journal for Research in Applied Science and Engineering Technology  
A peer-to-peer model training can also be implemented using a blockchain network. The blockchain database can be helpful in improving the quantity and quality of data.  ...  It is a decentralized way to store value transactions across the nodes in the network. Every node in the network has access to the ledger.  ...  In a traditional system transaction system, during a transaction, a centralized authority is required to process the transaction.  ...

Reasonableness discussion and analysis for Hyperledger Fabric configuration [article]

Song Hua, Shenbin Zhang, Bingfeng Pi, Jun Sun, Kazuhiro Yamashita, Yoshihide Nomura
2020 arXiv   pre-print
Fabric has various components such as peer, ordering service, chaincode and state database. The structure of Fabric network is very complicated to provide reliable permissioned blockchain service.  ...  Generally, developers must deal with hundreds of parameters to configure a network. That will cause many reasonableness problems in configurations.  ...   State database security CouchDB is implemented as a separate database process in the outside of peer.  ...

Performance Tuning and Scaling Enterprise Blockchain Applications [article]

Grant Chung, Luc Desrosiers, Manav Gupta, Andrew Sutton, Kaushik Venkatadri, Ontak Wong, Goran Zugic
2019 arXiv   pre-print
In this paper, we first develop a methodical approach to performance tuning enterprise blockchain applications to increase performance and transaction capacity.  ...  As enterprises begin to adopt blockchain technology to solve business problems, there are valid concerns if blockchain applications can support the transactional demands of production systems.  ...  The current state of the blockchain is stored in a state database (stateDB) that the peer connects to (each peer has a state database).  ...

Research Paper on Land Registry Maintenance System Using Block Chaining Technology

Shloka P Turakhiya
2019 International Journal for Research in Applied Science and Engineering Technology  
Block chaining technologies are very safe in recent years. The block chain is a distributed digital ledger,DEcentralized , and keeps track of all transactions made through peer -to-peer network.  ...  Simultaneously attacks are also raising, therefor it's hard to manage database. Block Chaining is best solution for database management .  ...  The database is encrypted and stored in a distributed way. Databases are transaction updates every 10 minutes.  ...
