🔥 Hard-core technical knowledge: Merkle trees
The beauty of a Merkle tree is that a single short root hash can “lock in” a huge number of transactions, and any tampering—even with just one transaction—will be detected.
Light wallets rely on the data provided by the nodes they connect to. For large payments, it’s worth cross-checking a few block explorers to confirm.
The header of every $BTC block records a Merkle root that summarizes all the transactions in that block.
