‘Our Team Consists of True Leaders in Their Respective Academic Disciplines
The HSE International Centre of Decision Choice and Analysis studies a wide range of methods for analysing decision-making and possible scenarios for the development of natural, socio-economic, and political phenomena using various mathematical models. The application of advanced mathematical methods to forecasting helps to prevent negative outcomes and avoid erroneous decisions. The HSE News Service spoke to the centre’s director, Prof. Fuad Aleskerov, about its work.

Optimizing multi-party agreement protocols

P. 55–58.
Fedotov I., Anton Khritankov, Barger A.

Blockchain technology has developed rapidly over the last few years. A Blockchain network uses the multi-party agreement concept to reach an agreement on the transaction confirmation. As the technology is new, tools and techniques for blockchain verification are still under development. We explore optimization techniques of weighted multi-party agreements with stochastic properties in the current work. We represent a multiparty agreement as a discrete-time Markov chain and specification in a probabilistic linear temporal logic form. We demonstrate how to change the protocol parameters to satisfy the specification and illustrate the work of algorithms in experiments. Finally, we discuss the usage of proposed algorithms in the Hyperledger Fabric framework.

Automated Verification of Multi-Party Agreements and Scheduling of Sending Messages in Distributed Ledger Systems
Fedotov I. A., A. S. Khritankov, Obidare M. D., Programming and Computer Software 2023 Vol. 49 No. 5 P. 448–454
Multi-party agreements are used in distributed ledger systems and blockchain networks to reach an agreement on changes in the system. When one of the network participants proposes a transaction to be recorded, it should be first confirmed by certain network participants. A multi-party agreement or consensus determines who exactly these participants are. Based on the ...
