Merkle Trees and Patricia Tries

  • Topic

Merkle Trees, named after the computer scientist Ralph Merkle, are binary hash trees that enable efficient verification of large datasets. They employ a top-down approach, where each non-leaf node is the hash of its child nodes, and the root represents the entire dataset. Merkle Trees are widely used in blockchain technology to ensure the immutability and consistency of data blocks, making them a vital component in securing distributed ledgers.
