Thereby, underlying consensus algorithms are the core mechanism to achieve consistency in distributed infrastructures. Their application aims for transparency and accountability in societal transactions. As a result of missing reviews holistically covering consensus algorithms, we aim to (1) identify prevalent consensus algorithms for public blockchains, and (2) address the resource perspective with a sustainability consideration (whereby we address the three spheres of sustainability). Our systematic literature review identified 33 different consensus algorithms for public blockchains. Our contribution is twofold: first, we provide a systematic summary of consensus algorithms for public blockchains derived from the scientific literature as well as real-world applications and systemize them according to their research focus; second, we assess the sustainability of consensus algorithms using a representative sample and thereby highlight the gaps in literature to address the holistic sustainability of consensus algorithms.}, language = {en} } @article{EigelshovenGronauUllrich2020, author = {Eigelshoven, Felix and Gronau, Norbert and Ullrich, Andr{\´e}}, title = {Konsens-Algorithmen von Blockchain}, series = {Industrie 4.0 Management : Gegenwart und Zukunft industrieller Gesch{\"a}ftsprozesse}, volume = {36}, journal = {Industrie 4.0 Management : Gegenwart und Zukunft industrieller Gesch{\"a}ftsprozesse}, number = {1}, publisher = {Gito}, address = {Berlin}, issn = {2364-9208}, doi = {10.30844/I40M_20-1_S29-32}, pages = {29 -- 32}, year = {2020}, abstract = {Neben dem enormen Kursanstieg des Bitcoins in den Jahren 2017/2018, stieg im gleichen Maß auch die ben{\"o}tigte Rechenleistung und der damit verbundene Elektrizit{\"a}tsbedarf, um Bl{\"o}cke innerhalb der Bitcoin-Blockchain zu verifizieren.
