Read propagation  refers to the ability of multiple nodes in a distributed system to respond to read requests simultaneously, thereby improving query performance. Write propagation refers to the ability of write requests to be performed simultaneously on multiple nodes, thereby increasing write throughput. Hybrid mode combines read propagation and write propagation to improve both query performance and data reliability and fault tolerance. In blockchain systems, these data synchronization patterns help enhance system performance and scalability. However, in practical applications, it is also necessary to consider issues such as network bandwidth consumption and data consistency."}]}],"pr":"cbdeecd320de71171d1eca5ba907a353b50d1dce8aec55ed7afaffc6dc6f3e20"}
