A Merkle Root is a cryptographic hash that summarizes all the transactions in a block. It is derived from a structure known as a Merkle Tree, which organizes and verifies large sets of data efficiently.In a Merkle Tree, transactions are split into pairs, and each pair is hashed together to create a parent node. This process continues until a single hash, the Merkle Root, is formed at the top. This root represents all transactions in the block, allowing for quick verification.When someone wants to check if a specific transaction exists in a block, they don’t need to examine the entire block. Instead, they can follow the path from the transaction upwards through the tree, hashing pairs along the way. If the final hash matches the Merkle Root, the transaction is confirmed as part of that block.The Merkle Root enhances data integrity and efficiency in blockchains, making it easier to secure and verify transactions without requiring comprehensive data access. This feature is crucial for maintaining the decentralized and secure nature of blockchain technology.
