Ethereum als eine stark befahrene Autobahn und Transaktionen als Autos
|
||||||
|
(Erklärung erdacht durch ein LLM). Rollups Vorgang:
|
||||||
|
\begin{itemize}
|
||||||
|
\item Sammeln von Transaktionen: Anstatt dass jedes Auto (Transaktion) auf der
|
||||||
|
Hauptautobahn (Ethereum) fährt, werden sie auf einem Parkplatz (Rollup)
|
||||||
|
gesammelt.
|
||||||
|
\item Verarbeitung außerhalb der Kette: Die Transaktionen werden in diesem
|
||||||
|
separaten Bereich verarbeitet, abseits der Autobahn.
|
||||||
|
\item Komprimierung: Nach der Verarbeitung wird eine \emph{mathematisch
|
||||||
|
äquivalente} Zusammenfassung aller dieser Transaktionen erstellt, fast wie
|
||||||
|
eine Liste der Autos, die durchgefahren sind.
|
||||||
|
\item Rückmeldung: Diese Zusammenfassung wird dann an das Ethereum-Netzwerk
|
||||||
|
gesendet und nimmt dabei viel weniger Platz ein, als wenn jedes Auto einzeln
|
||||||
|
auf der Autobahn gefahren wäre.
