Read More is a methodologyMethodology refers to practices, processes, rules, or guidelines used in systems development. Read More used to validate data structure and ensure data authenticity. The primary goal of this methodology is to organize large amounts of data to reduce the amount of work required to verify it. A Merkle Tree is created by hashing each nodeA computer that connects to a blockchain network. Read More in a dataset. Nodes are organized into a tree structure to compute the hashA “hash” is a fixed-length alphanumeric code that is used to represent words, messages and data of any length. Crypto... Read More of the entire tree (root). If data in a node changes, the root hash changes. As a result, only the root hash must compute to confirm the integrity of the entire dataset.
BlockchainsA blockchain is a distributed database that is shared among the nodes of a computer network.

Read More another transaction’s hash value and then hashes them together to create a combined hash value (i.e., hash values “AB” and “CD”’ combine to create the hash value “BCE”). The combined hash represents the paired hashes of the two transactions. This process of pairing hash values continues with each transaction added, culminating in a final hash value for the blockGroups of data within a blockchain. On cryptocurrency blockchains, blocks are made up of transaction records as users buy or sell... Read More (the Merkle root).
