The  leaf nodes of the Merkle tree store the hash values of the transaction data, while the non-leaf nodes store the hash values obtained by hashing the combination of all the leaf nodes below them. The height of the tree is log2(n), where n is the number of transactions. The root hash value (Merkle Root) of the Merkle tree is used to represent all transactions in the block in a concise manner, and serves as a part of the block header. Through the Merkle tree structure, the amount of calculation required for verification can be greatly reduced, requiring only"}]}],"pr":"5fbd4c06499fb2ec4368f1f69eabef1d0b3a785cabfbf0f7939298859b66ea31"}
