Unobtrusive monitoring: Statistical dissemination latency estimation in Bitcoin's peer-to-peer network

David Mödinger, Jan-Hendrik Lorenz, Rens W. van der Heijden, Franz J. Hauck, He Debiao
2020 PLoS ONE  
Measuring the dissemination latency requires many connections into the Bitcoin network, wasting network resources. Some third parties operate that way and publish large scale measurements.  ...  For risk estimation and usability aspects of Bitcoin applications, it is necessary to know the time required to disseminate a transaction within the network.  ...  Conclusion In this paper, we showed that overall dissemination times of transactions in the Bitcoin network can be estimated using the minimum number of connections required by the Bitcoin reference client  ...

A blockchain-based technique for making swarm robots distributed decision

E V Melnik, A B Klimenko, D Y Ivanov
2019 Journal of Physics, Conference Series  
The paper considers the problem of distributed decision making in the robot swarm.  ...  The decision making process is organized by means of distributed ledger usage.
