¿Qué es Merkle root?
A single hash in the block header that commits to every transaction in the block, built by hashing transactions together in pairs up a tree.
Because the root depends on every transaction, altering any one of them changes the root and therefore the block hash. The tree structure also allows a compact proof that a specific transaction is in a block without downloading the whole block.
That property is what makes lightweight verification possible for wallets that do not store the full chain.
