These tasks may include validating transactions, checking whether the block conforms to the blockchain protocol, calculating block rewards, and more. The BeginBlocker event allows developers to intervene in this stage, such as adding custom logic or filters to determine which transactions should be included in the upcoming block. In summary, the BeginBlocker event plays a crucial role in blockchain systems, providing the necessary preprocessing for creating valid blocks."}]}],"pr":"828c397d1c94cba60257bd3451944b9cf51b1d650573ce4357f81cd53f24b403"}
