It is a binary tree consisting of a root node, a set of intermediate nodes, and a set of leaf nodes. The lowest leaf nodes contain the stored data or its hash value, each intermediate node is the hash value of its two child nodes, and the root node is also composed of the hash values of its two subnode contents. In blockchain applications, Merkle trees are widely used to store and validate transaction data. For example, in Bitcoin and Ethereum, the transaction data of each block is organized into a Merkle tree structure."}]}],"pr":"40fc099f07d5fbc3bdce42c284bc979a4d78eb0f984f7cd54a1af730a59b8bed"}
