This approach prevents double-spending attacks, ensures the integrity of transaction order and data, and combines other security measures such as digital signatures and timestamps to achieve the goal of rent-free accounts in blockchain networks."}]}],"pr":"e6d16f859be260e67de11008f474d42f97b6240a5efdbcf07af9a4ae60b10405"}
