The random variables that randomly configure block proposers, aggregators, and validators in blockchain systems are not explicitly mentioned in the provided search results. However, in blockchain systems, various factors such as network latency, computational power, and stake size can influence the selection of block proposers, aggregators, and validators. These factors can be considered as random variables that affect the configuration of these roles in the blockchain network. If you have specific aspects or theories related to this topic, feel free to ask for more information.
