Abstract:

Thanks to the opportunities provided by developing technology, there had an increase in the transactions carried out using the internet. This development also led to an increase in data. This situation created the need for new technology for businesses to store, share, control, and manage data securely. One of the current technologies that can be used in this context is the blockchain structure. The blockchain structure is a technology that can be used in many areas, and the most popular usage area today is cryptocurrencies. In this study, it is aimed to estimate Polkadot cryptocurrency, which is one of the essential sub-cryptocurrencies. In the study, the data between 20.08.2020 and 27.02.2023 are used. According to these data, it aimed to estimate the daily average Polkadot value as the output value. Clusters for input values are created in two different ways. In the first input values; number of Polkadot YouTube search, number of Polkadot Google search, and Polkadot volume are used. Unlike the first input values, Ethereum, the leader of the alt cryptocurrencies, is added in the second input value. In this study, which consists of two different input structures, to estimate the daily average values of the Polkadot currency, an estimation study is carried out using multi-layered sensors in artificial neural networks and a long-short-term memory structure, which is one of the deep learning methods. When the results are examined, it is determined that the values of 4 input sets in the obtained artificial neural networks gave better results with a correlation coefficient of 0.93.
