Hash Tree: In a hash tree, each node stores a hash value of the combination of its child nodes. The root node stores the hash value of all the nodes beneath it. This type of Merkle tree is used in the Bitcoin blockchain to verify transactions.↵↵2. Pattern Tree: A pattern tree is a Merkle tree where each node stores a pattern of its child nodes' hash values. The root node stores the pattern of all the nodes beneath it. This type of Merkle tree is used in some privacy-preserving blockchain solutions, such as Monero.↵↵In both types of Merkle trees, the main purpose is to provide a secure and efficient way to verify data integrity and authenticity. The hash tree is used to verify transactions in a blockchain, while the pattern tree offers additional privacy features by obfuscating the details of individual transactions.","a":"There are two main types of Merkle tree structures in blockchain: Binary Merkle Tree and Compressed Merkle Tree. The Binary Merkle Tree is a Merkle tree organized in a binary tree structure, where each node can  have at most two child nodes. The Compressed Merkle Tree is an optimized version of the binary Merkle Tree, which reduces storage and computational costs by reducing the storage space of nodes. In blockchain, both types of Merkle tree structures are used to quickly verify the integrity and authenticity of transaction data."}]}],"pr":"030d87f5d27765094f407891b2338e01ee5db682a666040e33961230fc524a67"}
