Optimizing Blockchain Consensus: Incorporating Trust Value in the Practical Byzantine Fault Tolerance Algorithm with Boneh-Lynn-Shacham Aggregate Signature
...Show More Authors

The consensus algorithm is the core mechanism of blockchain and is used to ensure data consistency among blockchain nodes. The PBFT consensus algorithm is widely used in alliance chains because it is resistant to Byzantine errors. However, the present PBFT (Practical Byzantine Fault Tolerance) still has issues with master node selection that is random and complicated communication. The IBFT consensus technique, which is enhanced, is proposed in this study and is based on node trust value and BLS (Boneh-Lynn-Shacham) aggregate signature. In IBFT, multi-level indicators are used to calculate the trust value of each node, and some nodes are selected to take part in network consensus as a result of this calculation. The master node is chosen from among them based on which node has the highest trust value, it transforms the BLS signature process into the information interaction process between nodes. Consequently, communication complexity is reduced, and node-to-node information exchange remains secure. The simulation experiment findings demonstrate that the IBFT consensus method enhances transaction throughput rate by 61% and reduces latency by 13% when compared to the PBFT algorithm.

What linguists mentioned about the infinitive and its use in the linguistic levels of speech, whether with its verb, or what was mentioned in the difference between the infinitive and the noun of the source, are matters that are related to the phenomenon of hearing in speech, a need necessitated by the nature of the linguistic law and its connection with the Arabic dialects, which proceeded in the linguistic levels to form Phenomenon inherent in the use of the source and the name of the source

It is known that the distinguished scholar and writers in any kind of science leave an important impact on those who come after them, so they are an indispensable source in that science that draws from them who is later in time than them, and this is what we have seen in this research; The scholar Muhammad bin Shuraih al-Ra’ini (d.476 AH) and his book          (Al-Kafi in the Seven Readings) were admired by everyone who wrote about the readings after him. The great scholars of the readings, such as Ibn al-Bathish (d. 540 AH), Ibn al-Jazari (d. 833 AH), and Ibn al-Banna’ did not dispense with him. (d.1117 AH) in terms of reading, isnad, and the way of narration, their books were full of men

LA PESTE : PROJET IDEOLOGUIQUE
...Show More Authors

Nous tenterons dans ce travail de proposer une des lectures possibles de
l’oeuvre camusienne, en l’occurrence La peste. Il s’agit, pour nous, de lire ce roman
sur une portée idéologique. Et ce qui justifie notre tentative, c’est Camus lui-même
qui voudrait qu’on lise son roman " sur plusieurs portées " lorsqu’il déclare : « La
peste, dont j’ai voulu qu’elle se lise sur plusieurs portées, a cependant comme
contenu évident la lutte de la résistance européenne contre le Nazisme»1.
