This year the team of cryptocurrency Dash and Laboratory studies of the blockchain when Arizona state University announced a partnership on a 350 thousand US dollars.
In the framework of this partnership, a study was conducted “Distribution of units with respect to the network Nakamoto”, highlighted a number of scaling issues and the potential of blockchain Dash.
In each simulation Dash is used at least 6 000 nod – the researchers felt this number suitable for the current network conditions and for situations that are waiting for the Dash within the next few years. In order to obtain the necessary variability, each simulation had to last long enough to create at least 700 units.
The researchers proceeded from the fact that all network members mainile blocks of the same size. The most important limiting factor they have considered the network bandwidth and therefore focused on three different protocols of distribution blocks.
“We simulated a network of Dash using the three Protocol distribution blocks: a) traditional distribution, in which the block extends as a whole, b) a compact distribution (Cor16)) ultrascope distribution (Tsc16)”, – stated in the study, which is sponsored by Dragan Boskovice, Nakul Chawla and Darren Tapp.
The researchers came to the conclusion that when using ultrascope distribution network Dash will work more efficiently if you increase the block size to 10 MB, and when using compact distribution if you increase the block size to 6-8 MB.
The researchers also concluded that when using a compact and UltraScale protocols realistic to use units larger than 10 MB, but while maintaining a reasonable level of orphan blocks (approx. — refers to blocks that do not fall into the main blockchain cryptocurrency).
At the same time, the study authors determined that when using the traditional Protocol blocks larger than 896 KB unprofitable, because the transaction fee in this case does not provide miners adequate remuneration with an increased level of orphan blocks.
“As the network scale should be considered an economic incentive for miners from inclusion in the unit of a larger number of transactions. Assuming that the size of the fee is 0.1 DASH for MB, the economic level of orphan blocks is increased by 2.15% for MB, and the reward for mining is 1.67 DASH, we can assume that the blocks are above a size 896 KB mine will be unprofitable”, – added the researchers.
Therefore, with regard to the use of the traditional Protocol for the distribution blocks, the researchers recommend that the limitation on the block size does not exceed 5 MB, and I advise you not to expect that miners will be willing to generate blocks of more than 890 KB.
In the future within the framework of this partnership, researchers at the University of Arizona plan to work on simulations with a more three-dimensional blocks, and to create an independent test network for emulation of network Dash.
