Virtual blocks do not exist in actual physical blocks but are used to simplify the  operation and understanding of blockchain networks. Through virtual blocks, we can better analyze and study the topology, transaction relationships, and security issues of blockchain networks."}]}],"pr":"615da0a96cb3baf98f5e8206e3a8cecf278b0b4298b31b6fca78be803ba9708b"}
