What is the Merkle root of a bitcoin block?

For a bitcoin block to be valid, the block's header must hash to an output that is within a certain range of values (defined by the current network difficulty). The merkle root is one component of the block header, so in effect the merkle root is a cryptographic commitment to the transactions included in the block.

What is the Merkle root of a transaction?

Every transaction has a hash associated with it. In a block, all of the transaction hashes in the block are themselves hashed (sometimes several times — the exact process is complex), and the result is the Merkle root. In other words, the Merkle root is the hash of all the hashes of all the transactions in the block.

How does bitcoin use Merkle trees for verification of transactions?

This tutorial is written to simplify the understanding of how bitcoin uses merkle trees for verification of transaction into a block. A merkle root is created by hashing together pairs of TXIDs, which gives you a short yet unique fingerprint for all the transactions in a block.

What happens if you change the Merkle root?

Changing any single transaction (or the order of transactions) would alter the merkle root, and thus alter the block's hash (which, by overwhelming probabilty, would make the block invalid). With respect to A: To do this, wouldn't you just look at the list of leaf hashes to determine whether H (D) is there? Why do anything with the Merkle root?
