Blockchains store a lot of information. A Merkle Tree is like a super efficient filing system for this data. Imagine each piece of information is a document, and the Merkle Tree is a filing cabinet. It uses a special coding system (hashes) to organize everything. The cool thing is, even if one document gets changed, the whole filing system reflects the change. This lets you quickly verify the integrity of the entire blockchain by just checking a single code at the top (the root hash). It's like a security measure to ensure everything on the blockchain is accurate.
