The IAVL+ tree is a self-balancing binary search tree, which is used to store and query state root hashes in blockchain efficiently. It has high write and query  performance and can maintain consistency in a distributed environment. The Simple Tree is a simple unbalanced tree also used for storing data in blockchain, but its performance is relatively low, mainly used for lightweight query operations. These two data structures play essential roles in blockchain, providing efficient solutions for storing, retrieving, and validating transactions and state information."}]}],"pr":"9221149a861c6fc35fac4029935bf0b4b7dc0ed83b32256f7df637ac3b11b0ec"}
