  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. Aus diesem Problem ableitend besch{\"a}ftigt sich dieser Beitrag mit der Fragestellung, welchen Beitrag unterschiedliche Konsens-Algorithmen innerhalb einer Blockchain zur Nachhaltigkeit liefern. Im Ergebnis liegt ein {\"U}berblick {\"u}ber die meist genutzten Konsens-Algorithmen und deren Beitrag zur Nachhaltigkeit vor.},

  abstract  = {Blockchain has the potential to change business transactions to a major extent. 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.},
