Question about Merkle trees and blocks There is something I cannot understand about Merkle trees. I understand how they are calculated and etc., but I cannot understand how they are used on a blockchain. If a block stores only the Merkle root, how can a blockchain explorer let you search and view specific transactions? I think this requires that a block must store the whole array of transactions, not just the Merkle root. Please help me understand this. Thanks in advance.
The block header contains the merkle root, but the full block itself contains all the transactions, in order of their appearance as merkle leaves.
