Ein Blick auf aktuelle Entwicklungen bei Blockchains und deren Auswirkungen auf den Energieverbrauch

Abstract: Zusammenfassung Der enorme Stromverbrauch von Bitcoin hat dazu geführt, dass in Wissenschaft und Praxis oft eher undifferenziert Diskussionen über die Nachhaltigkeit von Blockchain- bzw. Distributed-Ledger-Technologie allgemein geführt werden. Allerdings ist die Blockchain-Technologie bereits heute alles andere als homogen – nicht nur hinsichtlich ihrer Anwendungen, die mittlerweile weit über Kryptowährungen hinaus in Wirtschaft und öffentlichen Sektor reichen, sondern auch bezüglich ihrer technischen Charakte… Show more

“…Sedlmeir et al [7] undertake a basic comparison of different DLT architectures with the conclusion that the energy consumption differs significantly depending on the design chosen. A further study by the same authors [18] refines previous models for Bitcoin's power consumption, such as the one by Vranken [19], and emphasizes that the driving forces behind power consumption are the Bitcoin price and the availability of cheap electricity. Eshani et al [20] use a linear regression model to predict Ethereum's energy consumption based on the observed hash rate and difficulty level; however, the use of simplistic interpolation techniques alone is likely not an appropriate method for PoW blockchains [10].…”

“…Some authors have focused on the price of the Bitcoin and analysis of financial bubbles (Agosto and Cafferata 2020;Azamjon et al 2016;Gibbons 2018, 2019;Butek 2016;Deutsch 2018;Fantazzini and Kolodin 2020;John et al 2022;Kiffer and Rajaraman 2021;M'bakob 2024;Phiri 2022;Prasad 2022;Riposo 2023;Sedlmeir et al 2020;Wu and Hossain 2023), and others on the prediction of future developments (Cuthbertson 2024;Katanich 2024). Some researchers' works compare the development not only of Bitcoin but also of other cryptocurrencies (Albrecher et al 2022;Bakhtiar et al 2023;Cengiz 2021;Gkillas and Longin 2019;Katanich 2024;Kawaguchi and Noda 2022;Lucking et al 2019;Rashid et al 2023;Sen and Jena 2022;Singla et al 2023;Touloupou et al 2022;Trucíos and Taylor 2023;Vaddadi et al 2023;Yuan et al 2022).…”
