* The state store process is related to graph theory in the sense that the Ethereum blockchain can be thought of as a directed graph, * where each block represents a node and the links between blocks represent directed edges. * In this context, rolling back the state of Ethereum to a previous state can be thought of as traversing the graph in reverse, * from the current state to a previous state. * The process of reverting the state involves undoing the changes made in the blocks that have been added to the blockchain since the previous state. * This can be thought of as "reversing the edges" in the graph, effectively undoing the changes made to the state of Ethereum. * By thinking of the Ethereum blockchain as a graph, we can use graph theory concepts, such as traversal algorithms, * to analyze and manipulate the state of the blockchain.
